1 INTRODUCTION

This user documentation is designed to be a reference for the quality of water (QW) programs 

within the National Water Information System (NWIS). If you are a new user, the “Introduction” 

and “Getting Started” sections may be the right place for you to start. If you are an experienced 

user, you may want to go straight to the details provided in the “Program” section (section 3). 

Code lists and some miscellaneous reference materials are provided in the Appendices. The last 

section, “Tip Sheets,” is a collection of suggestions for accomplishing selected tasks, some of 

which are basic and some are advanced. These tip sheets are referenced in the main text of the 

documentation where appropriate. 

1.1 NWIS Description

As part of the U.S. Geological Survey (USGS) program of disseminating water data to the 

public, the Water Resources Discipline (WRD) maintains a distributed network of computers and 

fileservers for the storage and retrieval of water data collected through its activities at 

approximately 1.5 million sites. This system is called the National Water Information System 

(NWIS).

The NWIS is a distributed database in which data can be processed over a network of 

workstations and fileservers at USGS offices throughout the United States. The system is 

composed of four subsystems: the Ground-Water Site-Inventory System (GWSI), the WaterQuality System (QWDATA), the Automated Data Processing System (ADAPS), and the WaterUse Data System, which is composed of the Aggregate Water-Use Data System (AWUDS) and 

the Site-Specific Water-Use Data System (SWUDS).
QWDATA: Section 1.1 NWIS Description

Water Quality 2 NWIS User

• Many types of data are stored in the NWIS distributed and local databases, including: 

• site information, 

• time-series (flow, stage, precipitation, chemical), 

• peak flow, 

• groundwater, 

• water quality, and 

• water use.

The NWIS structure and the types of data available in its subsystems are shown in the figure 

below.

Water Quality 3 NWIS User

1.2 QWDATA System Description

NWIS provides for the use of one or more logical water-quality databases within one database, 

all accessed using one copy of the NWIS software. A logical water-quality database consists of a 

water-quality file (QWFILE), a station file (SITEFILE), and shared reference files. The 

QWFILE is a keyed-indexed file of database tables managed by a UNIX-based software system. 

This system allows records to be retrieved efficiently based on the values of selected data 

defined as KEY elements: agency code, site ID, begin date, begin time, end date, end time, and 

medium code. The SITEFILE is accessed for selecting water-quality records by SITEFILE data 

elements, such as site ID, site type, and location. Reference files, such as the parameter code file 

and the geologic-unit code file, are implemented as database tables and are used for checking the 

validity of data entry values. 

Each water-quality record to be stored is initialized by “logging in” the data, and this is typically 

done when field data are available. When a sample is logged in, a record number that is unique 

within each logical water-quality database is automatically assigned to each analysis. The record 

number may be used later to access the analysis for updating or viewing. Personnel who have 

access rights for entering data may log in analyses.

1.3 User Access and Setup

User access is controlled internally by USGS policies and procedures.

2.1 Terminology

2.1.1 Sample

An environmental sample is the portion of a media such as water, sediment, tissue, etc. collected 

from a site during a specific date and time or a range of dates for analysis. A sample in the 

database is uniquely identified by the key variables pertaining to sample collection: agency code, 

station number, begin date, begin time, end date, end time, and medium code. The results of the 

chemical analyses and physical determinations for an environmental sample are generally stored 

as one sample. The key variables are sometimes adjusted to separate samples that are 

hydrologically related but that cannot be stored as one sample. For example, quality-control 

(QC) samples are stored as separate samples using one of the designated QC medium codes. 

Samples from different depths or cross sections may use time to “off-set” samples that were 

collected at the same site on the same date. 

2.1.2 Result

Values derived from chemical analyses or physical determinations of a sample are stored in the 

database as results. Results are uniquely identified for each sample by a parameter code that 

defines the property or constituent measured. 

2.1.3 Parameter Code 

Parameter codes are five-digit codes used to identify the constituent or property measured in a 

sample and the units of measurement. Some parameter code definitions include information 

about the methods used to measure the constituent or property, but this level of information is 

not currently consistent in the naming system.

2.1.4 Record 

A record is equivalent in a numbered database to a single, uniquely identified sample. 

2.1.5 Record Number 

A record number is an eight-digit number that is automatically assigned to a sample when the 

sample is logged into the database. The number is composed of a three-digit water year that 

omits the millennium, followed by a 5-digit sequential number; for example, 00200075 is the 

75th sample entered in water year 2002. The record number is equivalent to the key variables 

that uniquely identify a sample and can be used instead of the key variables in most of the NWIS 

QW programs. These numbers are unique only within a database and must be used cautiously in 

an NWIS installation of multiple databases. When retrieving data from multiple databases within 

an NWIS installation, the table-retrieval program will accept a file that consists of rows listing 

the eight-digit record number followed by a two-digit database number. The two-digit database 

number will be used only by the table output and retrieval programs in QWDATA. 
QWDATA: Section 2 Getting Started

Water Quality 5 NWIS User

2.1.6 Site

A site is the physical location where a sample is collected or a measurement is made. 

Information about a site must be stored in the NWIS SITEFILE before any other data can be 

stored for that site. Equivalent terms: station. 

2.1.7 Station Number

A station number is typically an 8- to 15-digit number assigned to a sampling site when it is 

established in the NWIS system (Novak, 1985). The eight-digit numbers are generally 

downstream order numbers that increase in the downstream direction and are used for surfacewater locations on streams or rivers. Additional digits can be added to the eight-digit 

downstream order station numbers (up to a maximum of 15-digits) to achieve some sequencing. 

The 15-digit numbers are generally a combination of the latitude, longitude, and sequence 

number of the location. A sequence number is used to separate locations that are very close to 

each other. Equivalent terms: site ID or station ID. 

2.1.8 WATLIST 

WATLIST is an output file produced by batch input programs that contain (1) a listing of the 

records that were updated; (2) a cation-anion balance table, if the balance can be computed; (3) a 

listing of any generated error messages; and (4) a listing of chemical verification messages. 

2.1.9 Time Definitions

QWDATA requires the entry of a time datum during login of a sample. To simplify the 

discussion within this documentation and between sub-systems of NWIS, the following 

definitions have been established.

Time zone—a geographic polygon where time is observed using a particular offset (in hours) 

from Coordinated Universal Time (UTC). 

Time datum—a variable that combines the time zone and the daylight-saving time usage 

associated with a time measurement.

Watch time—the time-of-day used by the person making and recording a measurement or 

setting up an instrument to record measurements. The time-of-day recorded on field notes is 

converted to and from UTC within the database by using a watch-time datum.

Site-default time datum—the time datum normally used by a USGS office when recording time 

at a data-collection site. The date of the time measurement must be taken into account to 

determine the site-default time datum, since daylight-saving time is (typically) only in effect 

during the summer. Note: the time-zone component of the site-default time datum may, or 

may not, be the same as the time zone in which the data-collection site is physically located. 

Similarly, the daylight-saving-time component of the site-default time datum may not agree 

with the daylight-saving policy of the region surrounding the site.
QWDATA: Section 2 Getting Started

Water Quality 6 NWIS User

Locally observed time datum—the time datum that is commonly used by the populace near a 

data-collection site. (One might conceptualize this as the time datum used in the local television 

listings.) Conversion of a time measurement (in UTC) by using the locally observed time datum 

generates a measurement time-of-day that would be readily intelligible to a non-technical reader 

near the data-collection site.

An example is included to clarify the distinction between the site-default and the locally 

observed time datums. An office in the Eastern Time zone chooses to operate all gages in 

standard time year-round, even though the State where the office is located employs daylightsaving time. The site-default time datum in this case is EST, and the locally observed time datum 

is EDT for summer time dates.

Water Quality 7 NWIS User

2.2 Using the Interactive Programs

All interactive programs can be accessed from the main QWDATA menu. To start QWDATA 

type “qwdata” at the UNIX prompt, and then the main menu will appear. Detailed information 

about each of the menu options within QWDATA is available in Section 3 of this documentation.

2.2.1 Answering Prompts

When YES/NO questions are asked throughout the programs, an answer of “Y,” “y,” “YES,” 

“yes,” “N,” “n,” “NO,” “no,” or a blank will be accepted; any other answer should receive an 

error prompt and a repeat of the question. Similarly, where you may answer a prompt with 

“QUIT,” “Q,” “q,” or “quit” also will be accepted. Several programs request a numeric response 

to select an Option (1, 2, or 3). When numeric data are requested, it is not necessary to enter final 

decimal points; however, embedded decimal points must be entered. 

2.2.2 Cursor Control

Cursor control screen movement allows you to navigate from item to item, screen to screen, and 

to other parameters in the interactive programs. The valid cursor control characters and options 

are:

Enter Action

^D (Ctrl-D) Skip to next block

# Delete (clear) value

/ Move back one field

/x Continue at item number x

/+x Move forward (x) items, default x is 1

/-x Move back (x) items, default x is 1

/@ Continue at item with string @ in label

/p Back up to previous page (screen)

/n Advance to next page (screen)

/d Delete current parameter

/a Insert new parameter

/c Cancel editing of current record

/q Skip remaining items

To exit from the QWDATA system and discard the work of the current menu option, you can use 

Control-C. This will result in a query to be sure that you want to exit the software. 
QWDATA: Section 2 Getting Started

Water Quality 8 NWIS User

2.2.3 Default Values

You can use a carriage return to accept a default answer to a query in the interactive programs. 

The default answer is identified by “<CR> =” in angle brackets at the end of the query. Default 

values for data entry are shown in the entry forms and will be used if you do not change them. 

2.2.4 Mandatory Fields

Information that is required to store or retrieve data from the database is highlighted in the 

interactive screens.

2.2.5 Help with Valid Codes 

You may enter a “?” in a field to obtain help on the information expected for that field. Where 

help is not available, a message stating that help is not available will appear.

2.2.6 Boolean Logic 

In programs where criteria can be set to select sites, samples, or results, the default logic is for 

multiple criteria to all be “true” for a site, sample, or result to be selected. In some programs an 

option is provided for you to specify that if any of the criteria are “true,” then you should select 

the site, sample, or result. In these programs you select either “AND” or “OR” as the logic. 

“AND” Boolean logic expects all criteria to be true. “OR” Boolean logic expects any criteria to 

be true. When you enter more than two Boolean conditions, the software combines the third (and 

subsequent) condition by enclosing the previously entered logical expression within parentheses. 

For example, “A or B and C” is evaluated to mean “(A or B) and C.” 

2.2.7 Command Line Processing

You can enter UNIX commands from the NWIS QW menu screen (but not while running menuoption programs). You cannot use the UNIX commands while you are accessing a data entry 

field in the software. Note: Some optional settings may not work when used from within 

QWDATA. An example is the “rm” command. If this command requires a confirmation of 

the action outside of QWDATA, it will not require one from within QWDATA. Shell 

redirection and pipe commands do not work with the UNIX commands entered from the 

QWDATA menu screens. 
QWDATA: Section 2 Getting Started

Water Quality 9 NWIS User

2.3 Site-Level Information 

Site-level information includes data associated with the site being sampled. Most information for 

a site is stored in the NWIS SITEFILE, which can be accessed from the Ground-Water SiteInventory (GWSI) System of NWIS. All documentation for GWSI is available at 

http://pubs.usgs.gov/of/2005/1251/. 

A site must be established in the SITEFILE before any water-quality information can be added. 

A site is established by using the GWSI entry programs as discussed in the GWSI user 

documentation. Review Section 3.7.2 of this user guide for additional details.

Basic site-level information can be retrieved from the SITEFILE through two QWDATA output 

programs. For example, if parameter codes 81024 (drainage area), 72000 (land surface altitude), 

or 72008 (well depth) are requested in output and the values are not stored with the water-quality 

record, the software will retrieve the stored results for these parameter codes from the SITEFILE. 

This is only possible with the “Water Quality Table by Sample” or “Flat File by Sample” 

options. Also, some alphabetic parameter codes are available for retrieving site-level information 

from the SITEFILE through QWDATA. Alphabetic parameter codes are listed in Appendix A, 

Table 13. 
QWDATA: Section 2 Getting Started

Water Quality 10 NWIS User

2.4 Sample-Level Information

A sample in the database is uniquely identified by the key variables pertaining to sample 

collection: agency code, site identifier code, begin date, begin time, end date, end time, and 

medium code. The automatically generated sample information, the mandatory sample 

information that must be entered, and the optional sample information that may be entered are 

described below.

2.4.1 Record Number (Automatic)

Record Number is an eight-digit number assigned to a sample when it is logged into the 

database. The number is composed of a three-digit water year followed by a five-digit sequential 

number; for example, 00200075 is the 75th sample entered in water year 2002. The record 

number is equivalent to the key variables that uniquely identify a sample and can be used instead 

of the key variables in most of the NWIS QW programs. These numbers are unique only within a 

database and must be used cautiously in an NWIS installation of multiple databases. 

2.4.2 Agency Code (Mandatory, Key Variable)

Agency Code is a five-character code that defines the agency responsible for the data stored for a 

sample. The default value is USGS_ (where “_” is a blank). The other options for agency code 

are on your local NWIS installation in the file /usr/local/nwis/support/aanwdx.all.agency.

2.4.3 Station Number (Mandatory, Key Variable)

Station Number is typically an 8- to 15-digit number assigned to a sampling site when it is 

established in the NWIS system. The eight-digit numbers are used for surface-water locations on 

streams or rivers and are generally downstream order numbers that increase in the direction of 

the drainage basin outlet. The 15-digit numbers are generally a combination of the latitude, 

longitude, and sequence number of the location. A sequence number is used to separate locations 

that are very close to each other.

2.4.4 Begin Date (Mandatory, Key Variable) and Begin Time (Optional, Key Variable)

Begin Date is the date the sample was collected (or the first date for a sample that is collected 

over multiple days). The format is YYYYMMDD.

Begin Time is the time the sample was collected (or the first time for a sample that is collected 

over a date or time range). The format is HHMM. Although this is an optional entry, it is one of 

the key variables used to identify a sample. If the field is not populated, then a null will be used 

on retrieval.

2.4.5 End Date (Optional, Key Variable) and End Time (Optional, Key Variable)

End Date is the last date of a sample that is collected over multiple days. The format is 

YYYYMMDD.

The End Time is the last time of a sample that is collected over a date or time range. The format 

is HHMM.
QWDATA: Section 2 Getting Started

Water Quality 11 NWIS User

2.4.6 Time Datum

Time Datum (see Section 2.1.9) is a required code that represents the time zone and daylightsaving time indicators that define the times entered in the begin date and end date fields. This 

field will be populated with the site-default time datum from the SITEFILE for the sampling site 

entered, but the field can be changed to any valid time datum. A complete list of valid time 

datum codes is available in Appendix J – Table 1. 

2.4.7 Time-Datum Reliability Code 

Time-Datum Reliability code is a required code that represents the reliability of the time datum 

entered for a sample. This field will be populated with “K” (Known), but it can be changed to 

“E” (Estimated) if desired. Descriptions of valid time-datum reliability codes are available in 

Appendix J – Table 2. 

The time-datum reliability code is used by QWDATA to determine when the time datum appears 

on some output formats. If the code is set to “K,” the time datum will appear on all output 

formats. If the code is set to “T” or “E,” the time datum will not appear automatically. Review 

Section 3.4.3.4 for additional details. 

2.4.8 Medium Code (Mandatory, Key Variable) 

Medium Code is the medium from which the sample was collected (i.e., surface water, 

groundwater, sediment, tissue, etc.). The medium code is a three-character code that contains a 

“super” medium, a submedium, and an indicator whether the sample is an environmental or QC 

sample. A complete list of the valid medium codes is in Appendix A, Table 1.

2.4.9 Sample Type (Mandatory)

Sample Type is the type of sample collected (i.e., regular, replicate, blank, or spike). The default 

value for this code is “9” (Regular). The sample type codes are in Appendix A, Table 4.

2.4.10 Analysis Status (Mandatory) 

Analysis Status specifies the level of security of the sample (i.e., unrestricted, internal use only, 

and proprietary). The default value for this code is “U” (Unrestricted) for regular samples and “I” 

(Internal use only) for quality-control samples. Proprietary samples should be coded with a value 

of “P” (Section 2.14). Samples coded with “U” will be released to the public. The analysis status 

codes are in Appendix A, Table 5. 
QWDATA: Section 2 Getting Started

Water Quality 12 NWIS User

2.4.11 Hydrologic Condition (Mandatory) 

Hydrologic Condition is the hydrologic stage that is represented by the sample collected (some 

examples are: normal, falling, rising and peak). The default value for this code is determined 

from the sample medium. The hydrologic condition codes are in Appendix A, Table 2. 

2.4.12 Hydrologic Event (Mandatory)

A Hydrologic Event is a natural or human-related occurrence that is represented by the sample 

collected, for example, storm, drought, snowmelt, or other choices. The default value for this 

code is determined from the sample medium. The hydrologic event codes are in Appendix A, 

Table 3.

2.4.13 Geologic Unit Code (Optional) 

A Geologic Unit Code is interchangeably referred to as the “aquifer code” and is an eightcharacter code that designates the aquifer associated with groundwater samples. The codes are 

defined in the “Catalog of Aquifer Names and Geologic Unit Codes.” Use Option 4 of the 

Support Files submenu to help find the appropriate code. Entries of geologic unit codes will 

default to capital letters if lowercase letters are input. 

2.4.14 Lab Number (Optional)

Lab Number is the analytical laboratory identification number given to a group of bottles from 

one field sample that are received together in a shipment. 

2.4.15 Project Number (Optional) 

Project Number is the nine-character project code associated with the sample.

2.4.16 Organism Code (Mandatory only for plant or animal tissue media)

Organism Code is a numerical code identifying the source organism of a tissue sample. The 

organism codes that can be used in the NWIS are a subset of the Integrated Taxonomic 

Information System (ITIS) described at http://www.itis.gov/. 

2.4.17 Body Part Code (Mandatory only for plant or animal tissue media) 

Body-Part Code is a numeric code used to further qualify the tissue analyzed for a tissue sample. 

The body part codes are in Appendix A, Table 14. 

2.4.18 Sample Field Comment (Optional)

Sample Field Comment is a text field to hold information from the field about a sample that 

cannot be defined by the coded information in the system. 

2.4.19 Sample Lab Comment (Optional) 

Sample Lab Comment is a text field to hold information from the lab about a sample that cannot 

be defined by the coded information in the system. 
QWDATA: Section 2 Getting Started

Water Quality 13 NWIS User

2.4.20 Sample Collecting Agency (Optional) 

The sample Collecting Agency is an alphabetic code identifying the agency primarily responsible 

for collecting the sample. Valid collecting agency codes are in Appendix K, Protocol 

Organization Codes. A default value for this field can be set in this file on your NWIS system: 

/usr/local/nwis/data/auxdata/qw.conf. For details about how to use the qw.conf file, see Section 

3.8.

2.4.21 Sample Customer Code (Not stored)

Each sample is associated with a “Customer code” (also known as a “user code”), which consists 

of two or three letters or digits. The customer code is not stored in the database, but it may be 

used in batch-file versions of sample data to indicate which office should receive the sample and 

result data after analysis by the laboratory. The list of valid customer codes is maintained by the 

USGS National Water-Quality Laboratory (NWQL) in Denver, and it USGS users on the internal 

network can retrieve it from the Water-Quality Data Transfer System (QWDX) by selecting the 

“Retrieve limited QWDX Reports” option, and then selecting on the “QWDX Customers (WSC, 

etc) Report” option.

2.5 Result-Level Information

2.5.1 Remark Code 

Remark codes provide additional information about the magnitude (or absence) of a value. View 

the remark code with the value to avoid misinterpreting the value. The remark codes are in 

Appendix A, Table 6.

2.5.2 Value Qualifier Code 

Value qualifier codes provide information about the process used to determine an analytical 

value and, often, the remark code associated with the value. Up to three value qualifiers can be 

stored with any single result. The value qualifier codes are in Appendix A, Table 11.

2.5.3 Data Quality Indicator Code

Data quality indicator codes indicate the review status of a result, control the ability of a batch 

input program to overwrite a value, and affect the inclusion of a result in output. The data quality 

indicator codes are in Appendix A, Table 9.

2.5.4 Null Value Qualifier Code

Null value qualifier codes identify a failed measurement due to a field, lab, or shipment problem. 

The null value qualifier codes are in Appendix A, Table 10.

2.5.5 Laboratory Standard Deviation

Laboratory standard deviations are usually determined by the laboratory as an explanation of the 

uncertainty associated with a result value. The laboratory standard deviation field (LSDEV) 

provides the ability to round values on output by using this information. For radiochemical data, 

the LSDEV field is used to store the 1-sigma uncertainty for the value, as described in the Office 

of Water Quality Technical Memo 2008.06. 

2.5.6 Method Code 

Method codes composed of five alphanumeric characters identify the analytical method used to 

determine a value. You can display method codes can by using the Support menu Option 8, 

Display the Parameter Method Table, which is described in more detail in Section 3.6.8. 

2.5.7 Preparatory and Analysis Dates 

Preparatory and analysis dates are two fields used to identify the dates (YYYYMMDD) of the 

preparatory step and analysis at the laboratory.
QWDATA: Section 2 Getting Started

Water Quality 15 NWIS User

2.5.8 Preparatory and Analysis Set Identifiers

Preparatory and analysis set identifiers are two fields used to store the set identification code (up 

to 12 characters) of the preparatory set and analysis set at the laboratory.

2.5.9 Report Level and Report Level Type Code 

The report level is the numeric value associated with the analytical method when the result is 

determined. The report level type is a code used to identify the type of report level used for the 

method. The report level type codes are in Appendix A, Table 12.

2.5.10 Analyzing Entity 

The agency, organization, group, or company that analyzes the result is known as the analyzing 

entity. An eight-character code is used to identify the entity that analyzed the listed result.

Analyzing entities can be displayed by using the Support menu Option 9, Display Analyzing 

Entity and Collecting Agency Codes, which is described in more detail in Section 3.6.9.

2.6 Parameter Codes

The parameter codes are five-digit codes used to identify the type of result stored. The codes are 

documented in the “NWIS Parameter Code Dictionary” (PCD). You can search the PCD or list 

parameter codes from Options 2 and 3 in the Support Files submenu of the QWDATA menu. 

Selecting the appropriate parameter code may require some verification with the laboratory. The 

schedules run by the NWQL will contain the parameter code for the data that will be generated; 

therefore, it may be useful to check the NWQL catalog of schedules for help identifying the 

parameter code(s) needed. Only numeric parameter codes can be used to enter results into the 

NWIS system.

2.6.1 Calculated Value Parameter Codes

Results may be determined during output for selected parameters by using algorithms stored in a 

reference table. The parameter codes for these calculated values are user-specified during 

retrieval. For the calculation to succeed, the parameter codes needed for calculation must be 

stored. Most calculated parameter codes available in an analysis can be retrieved using the alpha

code – CALCV. Algorithms for the calculated parameter codes can be viewed or output in 

QWDATA through Option 7 in the Support Files menu. Any of these parameter codes may also 

be used to store values in the database, if desired. See Section 3.6.7 for more details.

2.6.2 Water Science Center-Specific Parameter Codes

Twenty-six parameter codes (99900–99925) are available in the PCD for use by individual 

Water Science Centers (WSCs). A WSC-specific code is used to store results for constituents 

that do not have a valid parameter code. Storing results in QWDATA allows them to be stored, 

tabled, graphed, or exported for use in statistical programs. The first five codes (99900–99904) 

have default rounding codes of 2, the second five (99905–99909) have default rounding codes of 

3, and the remaining codes (99910–99925) have default rounding codes of 5. For more 

information about rounding codes, refer to Sections 2.7.1 and 3.6.8. If WSC-specific parameter 

codes are included in a publication-style table, the heading for each parameter contains seven 

characters per line and seven lines of text. The heading may be modified by using an editor to 

accurately describe the constituent. Exceptions apply to a table produced as described in Section 

3.4.7. An example of a WSC-specific code table output is below.

Because the definitions for these parameter codes are WSC specific and they are not stored in 

QWDATA, it is recommended that the database manager keep a log of the definitions applied to 

these codes. New parameter codes can be requested instead of using these codes. 

2.6.3 Fixed Value Codes

QWDATA contains many parameter codes for which the result is not the outcome of an 

environmental measurement but rather a qualitative scientific observation or description. These 

types of parameter codes are referred to as “Fixed Value Codes,” and they have a small number 

of valid results that are related to a description. For example, parameter code 01035 (the severity 

of detergent suds) has the following valid results.

0 none

1 mild

2 moderate

3 serious

4 extreme

In other cases the result is not the outcome of an environmental observation, but instead further 

defines the sample. For example, Parameter code 99111 (quality assurance data type associated 

with sample) has the following valid results. 

1 no associated quality assurance data

10 blank

20 blind sample

30 replicate sample

40 spike sample

100 more than one type of quality assurance sample

110 cross-section information stored

200 other

A complete list of parameter codes that have fixed values and the corresponding valid results is 

in Appendix B.

Water Quality 18 NWIS User

2.6.4 Alpha Parameter Codes

Alpha parameter codes, which may include both alpha and numeric characters, are used in 

QWDATA to retrieve sample and result-level descriptions as well as groupings of other codes. 

The descriptions include information stored with the sample such as date, time, and sample 

record number. An example of an alpha parameter code that represents a grouping of parameter 

codes is “ADDPC,” which adds all numeric codes to a retrieval. Another example of an alpha 

parameter code that represents a grouping of parameter codes is “CALCV,” which adds all 

calculated parameter codes to a retrieval. A complete list of alpha codes is in Table 13 of 

Appendix A.

For output in a by-result format, only alpha parameter codes may be used to define the columns 

in the output. For more information on this type of retrieval refer to Section 3.4.4. 
QWDATA: Section 2 Getting Started

Water Quality 19 NWIS User

2.7 Numeric Information

Values in QWDATA are stored in the database by using double-precision floating-point 

representation, which yields 15–17 decimal digits of precision. Data stored with the result value 

allows the software to reproduce the precision of the input data when the double-precision stored 

value is retrieved as unrounded from QWDATA. The retrieval programs available through the 

QWDATA menus provide more limited precision. Precision of results produced through 

QWDATA is limited by the internally defined width of the output field, the rounding method, 

and rounding criteria selected. Even when unrounded results are requested, precision is limited. 

In general, no more than 8 digits are provided with the retrieval programs in QWDATA. Results 

used in calculations, or retrieved through other interfaces (such as SQL or ODBC), will be 

double precision. 

2.7.1 Rounding 

Water-quality values from NWIS may be output as rounded or unrounded. The unrounded choice 

will output the values as they were received from the lab and stored in the database. There are 

two choices for rounding values: (1) allow the software to determine how to round the result by 

using an existing laboratory standard deviation (Section 2.5.5) stored with the result or the value 

in the rounding array for the specific parameter and method, or (2) use a rounding code stored 

with each value. See Section 3.6.8 and Tip Sheet 5.19 for details about rounding codes. 

You can select only one of the two rounding options above per retrieval for “Data Output”

Options 3, 4, 5, or 6 (see Section 3.4.7). Option 7 for “Data Output,” however, allows multiple 

rounding options (Section 3.4.7). 

The first one is called “default rounding” and the second one is called “user-defined rounding.” 

Some user-defined rounding codes have been set to odd values, sometimes by input from the lab, 

and they may produce unexpected results. The most conservative and consistent option for 

rounding values at present is default rounding. 

User-defined rounding can be used if a rounding code is stored with the result. If a rounding code 

is not stored with a result, the software will use the value from the parameter-method reference 

table. To add a rounding code, you can use “Modify Samples or Results” from the main 

QWDATA menu. Rounding codes can be added on a large scale by using batch files. 

Uncensored, non-zero concentration values that round to zero are, in general, converted to a null 

value on output, with the remark set to “M” (constituent identified in sample, but not quantified). 

Many uncensored measurements, however, may be reported as zero, and those values will 

remain zero in the output. An example of an acceptable rounded-to-zero result is water 

temperature. Censored, non-zero concentration values that round to zero are reported with the 

same number of significant figures that were originally entered with the value. 

A rounding code of zero is not accepted by the system. New interactive entries with rounding 

codes of zero (usually generated by the software) require you to select a different rounding code 
QWDATA: Section 2 Getting Started

Water Quality 20 NWIS User

before the value will be stored. New batch entries with rounding codes of zero will replace the 

zero with the appropriate rounding code for that parameter and method. 

Programs within QWDATA present result values using the various rounding options. The table 

below summarizes the rounding options used by the various QWDATA programs.

2.7.2 Scientific Notation 

During input, the field for entering values in QWDATA is limited to 8 digits and a decimal 

place. Scientific notation can be used to store values that will not fit in the field because they are 

very small or very big numbers. The format for storing scientific notation is the mantissa 

number, “E,” and the exponential power-of-ten value. For example, .000000000023 would be 

stored as 2.3E-11, and 48,900,000,000 would be stored as 4.89E10. In some cases, the PCD 

rounding specifications cannot accommodate very small and very large numbers on output. In 

those cases, user-defined rounding can be selected for output. 

2.7.3 Negative Values 

Negative values may be stored in QWDATA for selected parameters. The types of parameters 

that can have negative values generally are field constituents or properties (for example, air 

temperature, in degrees Celsius, parameter code 00020) and chemical constituents that are 

isotopes (for example, radium 226 dissolved, in picocuries per liter, parameter code 09503). 

Some of the WSC-specific codes (99900–99909) also will allow negative values to be stored. 

A complete listing of the parameters that allow negative values is in Appendix H.

2.7.4 Zero Values

Zero values in the database are processed in different ways. The software accepts zeros during 

processing for all parameters; however, a zero may or may not be a valid value from a scientific 

point of view. For example, zero for a temperature is a valid measurement. Laboratory methods 

for measuring chemical constituents, however, do not actually measure zero, but instead censor 

values that are less than some laboratory reporting level. 

For some chemical constituents, zero may have been incorrectly stored for historical data values. 

You may censor these zero values on output. If you select “User Specified” for “Censoring of 

Zero Values” in the tabling options menu, a zero value will be converted to a null value and a 

remark code of U (material analyzed for, but not detected) will be reported. Section 3.4.3.4

describes the tabling options in further detail. A reference list of parameters that are known to 

have zeros reported for some historical data is in Appendix I. 

In some cases, the rounding specifications for a parameter in the PCD do not go to a decadal unit 

that is small enough for some result values and may result in the value rounding to zero. This is 

because laboratory methods are not accurate to that level, even though a laboratory measurement 

was made and reported. In this case, during output processing a small number would incorrectly 

round to zero, even though a number may be stored. Values that belong to constituents that have 

reporting units that are used to quantify the abundance of an analytical constituent within some 

unit of area, volume, mass, or weight cannot be zero. Where the rounding procedures cause a 

non-zero value to round to zero, an “M” (presence of material verified, but not quantified) will 

be displayed on output for parameters with the units contained in the table below. The majority 

of parameters where a value that is rounded-to-zero is replaced by an “M” are measured with the 

units shown in the table below.

2.8 Text Fields for Comments

Text comments can be included within QW records at the sample level and at the result level. 

Each of these two levels has two categories of comments, those from the laboratory and those 

from the field. In general, messages from the laboratory are sent directly from the laboratory and 

should not be edited or altered, although there are circumstances where this might be necessary. 

Messages from the field can be used to include information relative to the entire sample or to a 

specific result that cannot be characterized in another field. The recommended maximum length 

of these comment fields is 300 characters. 

NOTE: Output from QWDATA in flat files or other tabular form generally is limited to displaying 

approximately 50 characters of these text fields. If your comment is longer than 50 characters, you 

will not retrieve the complete comment in output. (The WATLIST and publication-export outputs 

include the entire text field contents.)

To retrieve these text fields, the following alpha parameter codes can be used when retrieving 

records.

2.9 Validation

Chemical and data validation checks are performed by the data entry programs and the data 

review and batch processing programs. 

2.9.1 Data Entry Validation

Data validation checks are performed in the login samples program (Option 1, described in 

Section 3.1), modify sample and results program (Option 2, described in Section 3.2), and batch 

processing programs (Option 8, described in Section 3.8). 

Data validations are performed for the following sample header items (items with an “*” are 

validated against the NWIS reference lists).

• Station number (exists in the Site file )

• Sample has been logged into the database (date, time, medium code) 

• Sample collection start and end date and times (before current time)

• Time datum appropriate for location of sample 

• Medium code* 

• Sample type code*

• Analysis status code*

• Hydrologic condition code* 

• Hydrologic event code*

• Geologic unit code* 

• Organism code*

• Body part code*

Data validations are performed for the following result items (items with an “*” are validated 

against the NWIS reference lists).

• Parameter and method codes*

• Result value (if fixed-value code*) 

• Rounding (the entry must be in the following set: 1,2,3,4,5,6,7,8,9, ':' , ';' , '<' , '=' , '>' , '?' 

, or '@' )

• Remark code*

• Data-quality indicator code*

2.9.2 Chemical Validation

Chemical validation checks are performed in the data review programs (Option 3, described in 

Section 3.3) and the batch processing programs (Option 8, described in Section 3.8) and the 

results are printed in the WATLIST. The chemical validation checks are available in the sample 

list and/or cation-anion balance (Option 4, described in Section 3.3.4), chemical validation 

checks (Option 5, described in Section 3.3.5), and create or modify ion balance specification 

options (Option 6, described in Section 3.3.6). 

A detailed listing of the chemical validation checks in QWDATA is listed in Appendix M. In 

general these checks include the following items. 

• Field measurement results against general guidelines

• Chemical logic

• Bacterial logic 

• Comparisons between stored calculated parameters and current calculated values

• Comparisons between related constituents 

• Comparisons between unfiltered and filtered constituents 

• Comparisons between selected constituents and individual parameters that make up the 

sum of parts 

• Comparisons of constituents to alert limits in Appendix E

• Comparisons of constituents to custom, user-specified alert limits that are described in 

more detail in Section 3.3.5. 

• Calculation of a standard or customized cation/anion balance 

• The custom balance option is described in more detail in Section 3.3.6.

2.9.2.1 User-Specified Alert Limit Forms

The data review and batch-processing programs automatically compare selected constituent 

values to U.S. Environmental Protection Agency (EPA) Drinking Water Maximum Contaminant 

Levels and Secondary Maximum Contaminant Levels. Users also may need to compare results to 

other Federal, State, and local regulatory standards for waters used for specific purposes. Userspecified alert limit forms are used by data review and batch-processing programs in QWDATA 

to provide users with the option to compare results to these other Federal, State, and local 

regulatory standards.

2.9.2.1.1 List of User-Specified Alert Limit Forms Available

You can view a list of available user-specified alert limit forms by going to the following 

directory: /usr/local/nwis/data/auxdata/qw_alert_limits. In this directory are several files with 

the format alert.limitnn. The “nn” represents a two-digit number that identifies the form (e.g., 

alert.limit01). Use any UNIX editor to view the contents of these ASCII files.

2.9.2.1.2 Adding a New User-Specified Alert Limit Form

You can add new user-specified alert limit forms for use in QWDATA by creating a form using 

a specific format and storing it in the /usr/local/nwis/data/auxdata/qw_alert_limits directory. 

Create new user-specified alert limit forms if none of the available forms fit the data to be 

entered. Review the available user-specified alert limit forms prior to creating a new form to 

avoid duplicating forms. 

To make a new user-specified alert limit form, change directories to

/usr/local/nwis/data/auxdata/qw_alert_limits. Choose the user-specified alert limit form number 

to be used for the new form by listing the alert limit forms in the directory. Alert limit form 

names are in the format alert.limitnn where “nn” is the two-digit number that identifies the form. 

Choose a form number that is not already in use. Use any UNIX editor that produces an ASCII 

output file to create or edit an alert limit form file. Use the first line of the form to document the 

purpose of the form by placing a “#” character in the first column. Use additional lines for 

comments as long as a “#” character is in the first column of the line. Each alert limit line 

contains (1) parameter code, (2) logical operator for limit, (3) alert limit value, and (4) alert limit 

name. These values are separated by a <tab> character. An example of a user-specified alert limit 

form is shown Appendix G.

2.10 Field Forms 

Field forms are used by interactive entry of data and edit programs in QWDATA to provide a list 

of parameters that are routinely collected for a particular project, field trip, WSC water-quality 

field sheet, or data from a non-USGS laboratory. Field forms are a list of parameter codes and 

associated information that are accessed by various programs so that a user can enter efficiently 

field or laboratory data. Each field form is identified by a unique number that is part of the field 

form name. Entry programs for field and laboratory data are discussed in Sections 3.2.1 – Enter 

Field Results, 3.2.2 – Enter Laboratory Results, and Tip Sheet 5.2.

2.10.1 List of Field Forms Available

You can view a list of available field forms either by going to the directory where the forms 

reside or by listing them within QWDATA. To view the available forms in the directory where 

they reside, change directories to /usr/local/nwis/data/auxdata/qw_field_forms/. In this directory 

there are several files with the format field.parmsnn. The “nn” represents a two-digit number 

that identifies the form (e.g., field.parms01). Use any UNIX editor to view the contents of these 

ASCII files.

Another way to list the available field forms is within QWDATA during data entry. The prompt 

shown below appears during data entry after the login of a sample and when Enter Field Results

or Enter Laboratory Results has been selected.

 Enter field form nn, ?nn for detail of form nn, ? for list of forms available: 

At this prompt, you can enter a “?” and a list of available field forms will appear that includes 

the form number followed by either a form title or a list of parameter codes in that field form. To 

view the details of a specific form, enter a “?nn” at the prompt above, where “nn” is the field 

form number of interest. A list of parameter codes and associated information will be displayed 

for that field form.

2.10.2 Adding a New Field Form

You can add new field forms can be added to be used in QWDATA by creating a form using a 

specific format and storing it in the /usr/local/nwis/data/auxdata/qw_field_forms directory. 

Create new field forms if none of the available field forms fit the data to be entered. Review the 

available field forms prior to creating a new field form to avoid duplicating field forms. 

To make a new field form, change directories to /usr/local/nwis/data/auxdata/qw_field_forms. 

Choose the field form number you are going to use for the new form by listing the field forms in 

the directory. Field form names are in the format field.parmsnn where “nn” is the two-digit 

number that identifies the form. Choose a field form number that is not already used. Use any 

UNIX editor that produces an ASCII output file to create or edit a field form file. Use the first 

line of the form to document the purpose, by placing the “#” character in the first column. Use 

additional lines for comments as long as “#” is in the first column of the line. The format and an 

example of a field form are shown in Appendix G.
QWDATA: Section 2 Getting Started

Water Quality 29 NWIS User

You can enter any numeric parameter into a field form. Alpha parameters (such as GUNIT for 

geologic unit code) cannot be used in the form. Be sure that the final line of the form ends with a 

carriage return. If you do not include a carriage return, the last parameter will not be included 

during data entry. A maximum of 100 parameters can be included in any field form. 

As part of creating new field forms, you can create descriptions for the parameter codes listed. 

Be careful not to create descriptions that could cause confusion when compared to the definitions 

in the PCD. For example, a parameter described as “chloride, dissolved” in the field form and 

defined as “chloride, total” in the PCD could cause incorrect data storage and interpretation, as 

well as significant future confusion. Creating a new field form is discussed in Tip Sheet 5.3.

2.11 Multiple Databases

Users have access to multiple water-quality databases where each database file is associated with 

a generic filename and a database number. A database number is a two-digit number, ranging 

from 01 to 99. Regardless of the number databases that are implemented on each system, any 

user who has not been assigned an alternate database number in the database selection table will 

be associated with database number 01. Additional information and instructions for 

implementing and using multiple databases are in the manual for the nwdb command.

2.11.1 When to Use an Alternate Database 

Within NWIS, users have the option to create and use multiple water-quality databases. The 

decision to create and maintain an alternate database is one that should be carefully considered to 

ensure that the needs being met by an alternate database are sufficient to outweigh the problems 

associated with maintaining two or more databases.

Some of the issues involved with having more than one database are: 

• duplicate data stored in multiple databases require that updates be applied to more than 

one database to maintain data integrity; 

• only data from database 01 will be displayed on NWISWeb; 

• an alternate database that is created for a specific project might be abandoned if the 

project chief leaves; 

• alternate databases require increased data management responsibilities; 

• interactive and batch entry results require setting the proper database number prior to 

NWIS use; and 

• automated loading of NWQL results require setup and use of a separate NWQL user 

code.

Prior to the release of NWIS 4.1, one of the major reasons for the creation of alternate databases 

was to prevent the release of data for which there should be no public access; for example, 

proprietary data (either permanent or temporary), cooperator data, and QA/QC data. With the 

release of the 4.1 revisions of QWDATA, codes are available for restricting access within the 

same database; however, sample coding must be rigorously correct if proprietary and publiclyaccessible data are stored in the same database. If proprietary data are segregated into an 

alternate database, these data can be excluded safely and easily from unauthorized users, 

including NWISWeb. 

Other reasons for having an alternate database include testing, training, and organization. For 

example, much NAWQA data is kept in an alternate database, because NAWQA study units 

generally are not aligned with WSC boundaries, and the primary responsibility for serving data 

to the public lies with the WSC that has jurisdictional responsibility for the site where the data 

were collected.
QWDATA: Section 2 Getting Started

Water Quality 31 NWIS User

The NWIS Program office recommends that an alternate QW database be used for storage of 

QA/QC and proprietary data to protect these data from accidental release to unauthorized sources 

in response to a public inquiry, or the inadvertent inclusion of the data in a report or on 

NWISWeb. 

WSCs should avoid the situation where multiple copies of the same sample data are stored in 

separate databases on the same NWIS installation, because keeping the multiple copies 

consistently up-to-date is difficult.

2.11.2 How to Set Up an Alternate Database

If you determine that an alternate database is needed, the directions are located on the NWIS 

internal website. They are not duplicated here because of changes that might be required as the 

NWIS software changes.

2.11.3 What Software Works with Multiple Databases

Multiple databases can be accessed when retrieving records and when creating output tables. 

You can access these options through Options 3 – “Data Review” or 4 – “Data Output” from 

the main QWDATA menu (see Section 3.3.2).

2.12 Quality-Control Samples

The recommended procedures for storing quality-control (QC) samples in NWIS are described in 

this section. QC data provide information about the bias and variability in the environmental 

data; therefore, the QC samples need to be identified in a manner that relates them to 

corresponding environmental samples. In addition, the QC samples need to be stored separately 

from the environmental samples to prevent any unintentional retrieval of these types of data. The 

recommended procedures address both of these requirements. 

2.12.1 Definitions of Quality-Control Samples

Blank samples are taken to ensure that environmental samples have not been contaminated by 

the data collection process. Any measured value/signal in a blank sample for an analyte (a 

specific component measured in a chemical analysis) that was absent in the blank solution is 

believed to be due to contamination. Many types of blank samples are possible, each designed to 

segregate a different part of the overall data-collection process including sampling, filtering, 

preserving, storing, transporting, and analyzing. 

Blank solution — Solution that is free of the analyte(s) of interest. Such a solution would 

be used to develop specific types of blank samples as described below. 

Shelf (or hold) blank — A blank solution put in the same type of bottle used for an 

environmental sample and stored adjacent to an environmental sample in a 

storage area. 

Refrigerator blank — A blank solution put in the same type of bottle used for an 

environmental sample and stored adjacent to an environmental sample in a 

refrigerated storage area.

Trip blank — A blank solution put in the same type of bottle used for an environmental 

sample and kept with the set of sample bottles both before and after sample 

collection.

Sampler blank — A blank solution poured or pumped through the same field sampler used 

for the collection of an environmental sample. 

Filter blank — A blank solution filtered in the same manner and through the same filter 

apparatus used for an environmental sample. 

Splitter blank — A blank solution mixed and separated using a field splitter in the same 

manner and through the same apparatus used for an environmental sample.

Preservation blank — S blank solution treated with the same preservatives used for an 

environmental sample. 

Field blank — A blank solution subjected to the same aspects of sample collection, field 

processing, preservation, transportation, and laboratory handling as an 

environmental sample. 
QWDATA: Section 2 Getting Started

Water Quality 33 NWIS User

Equipment blank — A blank solution processed through all equipment used for collecting 

and processing an environmental sample (similar to a field blank, but normally 

done in the more controlled conditions of the office and not transported to the 

field).

Ambient blank — A blank solution put in the same type of bottle used for an 

environmental sample, kept with the set of sample bottles before sample 

collection, and opened at the site and exposed to the ambient conditions. 

Source solution blank — A blank solution sent to a laboratory to confirm that it is free of 

the analyte of interest.

Lab blank — a blank solution prepared in the laboratory and analyzed the same as an 

environmental sample. 

Blind sample — A sample submitted for analysis whose composition is known to the 

submitter but unknown to the analyst. A double-blind sample is one of known 

composition that is submitted to the analyst in such a manner that neither its 

composition nor its identification as a check sample is known to the analyst. A 

blind sample is one way to test the proficiency of a measurement process. Blind 

samples can be used to monitor the performance of an analytical system, check 

the analytical results of more than one laboratory, more than one analytical 

method, or the consistency of the same laboratory and method. Every blind 

sample analyzed should have an associated reference to the source and the 

possible dilution. Blind samples may be prepared from a reference material, as 

defined below. 

Reference material — A material or substance, one or more properties of which are 

sufficiently well established, to be used for the assessment of a measurement 

method or for assigning values to materials. 

Replicate (Duplicate) samples — a group of samples, collected so that they are intended to 

be essentially identical in composition. Replicate is the general case, for which 

duplicates are the special case and consist of two samples. Many types of 

replicate samples are possible, each of which may yield slightly different results 

in a dynamic hydrologic setting, such as a flowing stream. The types of replicate 

samples are:

Concurrent samples — samples collected by two or more people collecting 

samples simultaneously or by one person alternating sub-samples between two or 

more collection bottles;

Sequential samples — a type of replicate sample in which the samples are 

collected one after the other, typically over a short time; and

Split samples — a type of replicate sample in which a sample is split into 

subsamples contemporaneous in time and space. 

Spike sample — A sample to which known concentrations of specific analytes have been 

added in a manner that minimizes the change in the matrix of the original 

sample. Every spiked sample analyzed should have an associated reference to the 

spike solution and the volume added. 
QWDATA: Section 2 Getting Started

Water Quality 34 NWIS User

Spike solution — A solution with one or more well-established analyte concentrations that 

are added in known quantities to an environmental sample to form a spike 

sample.

2.12.2 Identification of Quality-Control Samples in NWIS

A system for identifying quality-assurance samples and maintaining the relationship with 

corresponding environmental samples has been established. The MEDIUM CODE, DATE, 

TIME, and SAMPLE TYPE are used in the following manner to clearly identify all QA data.

Blank 

• Use the actual STATION NUMBER, DATE, and TIME for blanks associated with a 

specific site and environmental sample. Use a laboratory STATION NUMBER, DATE, 

and TIME for blanks that are associated with many sites and/or environmental samples. If 

more than one blank is analyzed, increment the TIME by 1 minute for each blank. 

• Use a MEDIUM CODE of OAQ.

• Use a SAMPLE TYPE of 2.

• You may wish to use HYDROLOGIC EVENT and HYDROLOGIC CONDITION of X.

• Use 991xx parameter codes listed below to designate the type of blank solution, the 

source of the blank solution, and the type of blank sample. Use 992xx codes listed below 

to record a solution lot number. 

• If more than one blank is collected, use parameter codes 82073 and 82074 to enter the 

same STARTING TIME and ENDING TIME for each blank. Parameters 99109 and 

99110 can be used to enter the SAMPLE SET START DATE and SAMPLE SET END 

DATE for a blank associated with environmental samples collected on more than 1 day. 

Blind 

• Use the actual STATION NUMBER, DATE, and TIME for blinds associated with a 

specific site and environmental sample. Use a laboratory STATION NUMBER, DATE, 

and TIME for blinds associated with many sites and/or environmental samples. If more 

than one blind is analyzed, increment the TIME by 1 minute for each blind. 

• Use a QC MEDIUM CODE.

• Use a SAMPLE TYPE of 4.

• Use 991xx parameter codes listed below to designate the source of the reference material 

and the source code number. 

• If more than one blind is collected or if a blind is related to more than one environmental 

sample, use parameter codes 82073 and 82074 to enter the same STARTING TIME and 

ENDING TIME for each blind. Parameters 99109 and 99110 can be used to enter the 

SAMPLE SET START DATE and SAMPLE SET END DATE for blind samples that are 

associated with environmental samples collected on more than 1 day.

Water Quality 35 NWIS User

Reference Material

• Assign a laboratory STATION NUMBER.

• Use the DATE and TIME that material was created or received.

• Select a QC MEDIUM CODE.

• Use a SAMPLE TYPE of 6. 

• Use 991xx parameter codes listed below to designate the source of the reference material 

and the source code number. 

Replicate

• Use the actual STATION NUMBER.

• Use the actual DATE and TIME for the first sample, and increment TIME by 1 minute 

(or actual times if greater than 1 minute) for each additional sample.

• Select an environmental MEDIUM CODE for the first replicate and a QC MEDIUM 

CODE for the second and subsequent replicates. 

• Use a SAMPLE TYPE of 7 for every sample, including the first one. A SAMPLE TYPE 

of 5 (duplicate) has been used in the past for the special case of replicates consisting of 

only two samples. The SAMPLE TYPE of 7 should be used for all samples that fit the 

definition of replicate included in this documentation. 

• Use the 991xx parameter code listed below for replicates to designate which of the 

methods was used to create the replicates.

• Use the same STARTING TIME and ENDING TIME (parameters 82073 and 82074) for 

all samples.

• If the replicate samples will be stored in the regular database, use normal MEDIUM 

CODES (i.e., WG or WS) and a sample type of 7. 

Spike

• Use the actual STATION NUMBER, DATE, and TIME for spikes associated with a 

specific site and environmental sample. If more than one spike is analyzed, increment the 

TIME by 1 minute for each spike. 

• Select a QC MEDIUM CODE.

• Use a SAMPLE TYPE of 1.

• Use the 991xx parameter codes listed below to designate the source code number of the 

spike solution, the spike type, and the volume of the spike. Use an existing code (32000) 

to designate the sample volume.

• If more than one spike is collected, use parameters 82073 and 82074 to enter the same 

STARTING TIME and ENDING TIME for each spike. Parameters 99109 and 99110 can 

be used to enter the SAMPLE SET START DATE and SAMPLE SET END DATE for 
QWDATA: Section 2 Getting Started

Water Quality 36 NWIS User

blind samples that are associated with environmental samples collected on more than 1 

day.

Spike Solution 

• Assign a laboratory STATION NUMBER.

• Use the DATE and TIME that source was created or received.

• Use a MEDIUM CODE of OAQ.

• Use a SAMPLE TYPE of 8.

• Use the 991xx parameter codes listed below to designate the source of the spike solution 

and the source code number of the spike solution. 

Assign an ANALYSIS STATUS code of “I” (Internal-use only) to each QC sample to prevent 

the data from being inadvertently released to the public. The following remark codes have been 

added to the system to allow further identification of some types of QA data: 

 A Average value, and

 S Most probable value.

Parameter code 99111, quality-assurance data indicator, can be stored with environmental 

samples to indicate that there are associated quality-assurance samples. The fixed values for 

99111 indicate the type of quality-assurance samples associated with the environmental samples.

Several existing parameter codes in addition to 82073 and 82074 are mentioned in the 

identification of samples above that would clarify the nature of the sample (both environmental 

and QA samples). A list is provided below to encourage the use of these parameters. The 

definitions for the fixed-value parameters are in Appendix B.

2.14 Proprietary Data 

Proprietary data consist of information obtained by the USGS for which the Bureau’s rights of 

ownership are restricted in a manner that limits our ability to freely distribute the data. 

Proprietary data restrictions may include copyright protection, homeland security issues, or 

specific agreements with cooperators. Internal-use data include analyses for quality-control 

samples, and are generally not available to the public. However, the majority of data are without 

distribution limitations. 

Within QWDATA, the analysis status code (ASTAT) can be used to identify the distribution 

limitations of the sample and all associated results. The data quality indicator code (DQI) can be 

used to specify review status and control distribution of individual results within a sample. Three 

optional codes for ASTAT (Section 2.4.10) can be set by editing the existing record (described in 

Section 3.2.3) or setting ASTAT for multiple records at one time (described in Section 3.7.5). 

The DQI code is introduced in Section 2.5.3. Proprietary samples should be set with an ASTAT 

of “P.” Proprietary samples will not leave the WSC database. 

Details about the data flow related to proprietary data are available at 

http://water.usgs.gov/admin/memo/QW/qw07.04.html, and

2.15 Data Entry Options 

Two methods are available for entering data using QWDATA—interactive data entry and batch 

data entry. Interactive data entry is entering data using queries and entry screens within the 

software. Batch data entry is using files as input to put data into the database. Both methods can 

be used to enter or modify data in the water-quality database if you have the required security 

access. In general, use interactive data entry to enter sample information (record creation), enter 

field data, and modify existing records for relatively small changes. Batch data entry is generally 

used for entering or modifying large amounts of data, for example, the input of results from 

laboratories. You can use either method to remove data from the water-quality database.

2.15.1 Interactive Programs

Use Option 1 on the QWDATA main menu to interactively log samples into the database. This 

option can be used to enter sample information and field data. A record number (see Section 

2.1.5) is generated after the sample information has been entered. For specific information about 

using this program see Section 3.1, Option 1 – Login Samples. 

Option 2 on the QWDATA main menu contains options for entering field data and laboratory 

results and editing samples or results. Option 2.1, “Enter Field Data,” allows you to add field 

water-quality data to existing records in the QWDATA database. Option 2.2, “Enter Laboratory 

Results,” allows you to add laboratory data to existing records in the QWDATA database. This 

option was primarily designed for entering data from non-USGS laboratories; field data also can 

be entered using this program. Option 2.3, “Edit Samples or Results,” allows you to edit and 

delete sample and result information for samples that exist in the QWDATA database. For more 

information on any of these options see Section 3.2, Option 2 – Modify Samples or Results.

Entering field or laboratory results by using any of the above interactive programs is done by 

using field forms. You can customize these forms to provide parameters of interest for particular 

data entry needs. More information about field forms is in Section 2.10 and Tip Sheet 5.3.

2.15.2 Batch Programs

Option 8 on the QWDATA main menu contains options for entering data by using batch 

programs. The programs available from this menu work with files of water-quality data and are 

used for a variety of data needs. The most common application is entering data from laboratories, 

most typically the USGS National Water Quality Laboratory (NWQL). Other uses of the batch 

programs and files are outputting entire records or groups of records by specifying the record 

information and making large scale changes to water-quality data in the QWDATA database.

The batch file format is a tab-delimited format. This tab-delimited format uses a pair of files, one 

for sample information and one for result information. This format was designed to 

accommodate new fields introduced in NWIS 4.1 and is expandable for fields introduced in 

future versions of the software. The file format is discussed in Section 3.8 and example batch 

files are shown in Appendix F. In previous versions of NWIS (release 4.7 and earlier), a fixed 

format, known as the “1 and *(or star)” card format, was also accepted. Specifically, that singlefile format was designed for use with NWIS versions prior to version 4.1. Usage of the 1 and * 

format was discontinued at NWIS 4.8. 
QWDATA: Section 2 Getting Started

Water Quality 41 NWIS User

The programs available when using Option 8 can process data into the database for existing and 

new records, including USGS Laboratory data retrieved from the QWDX, produce batch output 

in the tab-delimited format, and review or edit a set of tab-delimited batch files. Detailed 

explanation of these programs is included in Section 3.8.

Water Quality 44 NWIS User

The options at the bottom of the screen allow you to move from item to item, screen to screen, 

and to other parameters. The valid cursor control characters and options are shown at the bottom 

of the screen and are described in Section 2.2.2, Cursor control and Tip Sheet 5.1. The items on 

the “Login Sample” screen are described below and on Tip Sheet 5.2.

(1) The cursor is initially positioned at the “U” in “USGS.” If this agency code is correct, accept 

it by entering a carriage return; if not, enter any valid agency code (for example, “USEPA”), 

followed by a carriage return. A list of valid codes is available in documentation for the 

Groundwater Site Inventory System. 

(2) Next, position the cursor to the first blank following “Station Number:” and the program 

waits for input. Enter the station number, followed by a carriage return. At this point the program 

checks to determine if the agency code and station number (also referred to as “station 

identification,” “site identification,” “or site id”) are in the SITEFILE. If the agency code and 

station identification are found in the SITEFILE, the station name is displayed and the cursor 

moves to the next item. If the agency code and station identification are not found in the 

SITEFILE, an error message is displayed and the cursor returns to the first blank following 

“Agency Code.” 

(3) When a station number has been accepted, the cursor is moved to the first “Y” following 

“Begin Date.” The begin date is a required item and must be entered in the correct format

(YYYYMMDD). The date is checked for validity, including if the date is less than or equal to 

the current date; future dates are invalid. If the begin date is more than 1 year prior to the current 

date, a message is displayed and you can reenter the date. 

Note: For sample composites, the full end date (year, month, and day as YYYYMMDD) must be 

entered. There are no restrictions on composites that span the end of the month. The only checks 

made on end date are to ensure that the date is valid and the end date is not earlier than the begin 

date. (If a composite spans more than 31 days, a warning message is displayed and you can 

change the end date).

(4–6) The next three items (“Begin Time,” “End Date,” and “End Time”) are optional and may 

be skipped by entering carriage returns. 

(7) The “Time Datum” is a required item and is checked against a list of valid codes. This field 

will be automatically populated from the SITEFILE settings for the site entered. Type a “?” to 

display a list of valid time data on the screen. Additional information for the time datum is 

available in Sections 2.1.9 and 2.4.6, and a list of valid time datum codes is available in 

Appendix J, Table 1.

If a time datum that does not match the SITEFILE setting for the site is entered, the following 

warning will appear at the bottom of the screen. 

Warning! Time zone does not match site file settings. Re-enter (Y/N)?
QWDATA: Section 3.1 Option 1 – Login Samples

Water Quality 45 NWIS User

This is only a warning, because the time datum entered is unexpected, and you are given the 

chance to change it. There may be a valid reason for the time datum to be different, and the 

software will store the time datum entered.

When a daylight saving time datum for a sample date that is not during the daylight saving time 

period is entered, the following warning will appear at the bottom of the screen. 

Warning! Daylight saving time not normally used on this date. Re-enter (Y/N)?

This is an unusual circumstance and most likely is a mistake; therefore, you are given an 

opportunity to change the daylight saving time datum. 

For composite samples that contain a time period that straddles the daylight saving time date 

change, the standard time datum is recommended. For example, if the begin date is April 1, 

2002, and the end date is April 30, 2002, the standard time datum should be used. 

Eastern Standard Time (EST) should be used in the Eastern Time zone. If a daylight saving time 

datum is used, the following warning will appear at the bottom of the screen.

Use standard time datum if Start/End date is standard time. Re-enter (Y/N)?

This gives you the opportunity to change the value entered. 

(8) The “Time-Datum Reliability” code is a required item and is checked against a list of valid 

codes. This field will be automatically populated as “K” (known). You can change the value to 

any valid code. If the code entered is other than “K,” the time datum stored with the sample will 

not appear in all output formats. You can display a list of valid reliability codes on the screen by 

typing a “?”. Additional information for this field is available in Section 2.4.7, and a list of valid 

time datum codes is available in Appendix J, Table 2. 

(9) The Medium Code is a required item and is checked against a list of valid medium codes. 

Type a “?” to display a list of medium codes on the screen. The cursor is repositioned in the 

space following the medium code after the list is displayed. Medium codes are described in 

Section 2.4.8 and a list is available in Appendix A, Table 1.

(10–13) Default values are included in the Sample Type and Analysis Status fields after the 

medium code is entered. The default values are listed in Appendix A, Table 1. You can replace 

the default values by entering the desired value. Entering a “?” for any of the items displays a list 

of valid codes on the screen. Valid codes for sample type, analysis status, hydrologic condition, 

and hydrologic event are available in Appendix A, Tables 2, 3, 4, and 5. 

(14) If the medium code is anything other than WG--Groundwater or WGQ--QA sample - 

Groundwater, the Geologic Unit Code item is skipped. Display a valid list of geologic unit codes

by typing a “?” and at least two characters of the geologic unit code or name. You can view valid 

codes by using the check support files, Option 6, described in Section 3.6.4. A complete list of 

valid geologic unit codes is in the file /usr/local/nwis/support/aageol.states.all.

(15) The Lab Number item refers to the lab identification number, which is established when the 

sample is received at the USGS National Water Quality Laboratory. Normally, you would not 

know the lab number when you login the sample, and leave this item blank by entering a carriage 

return. If you enter a value is during initial login, then that value will not be updated by 

subsequent lab-data input programs. 

(16) The Project Number allows you to enter a project identifier. 

(17) Samples with the medium codes BA--animal tissue, BP--plant tissue, BAQ--quality 

assurance sample-animal tissue, or BPQ--quality assurance sample-plant tissue automatically 

convert Organism Code to a required item. To search for valid organism codes, type a “?” and at 

least two characters that appear in the organism name, followed by a carriage return. To improve 

the results of the search, enter as many characters as are known; shorter entries could result in a 

long list of results. The organism codes can also be found in the Integrated Taxonomic 

Information System at http://www.itis.gov/. 

(18) Login of samples with medium codes of BA, BP, BAQ, or BPQ automatically converts 

Body Part Code to a required item. Display valid body part codes by typing a “?” followed by a 

carriage return; see Appendix A, Table 14. 

(19–20) If a sample comment (either Field or Lab) item has not been entered, an “N” appears 

between the “:” and the “Add?” query. If you enter a “Y” and a carriage return after the “Add?”

query, a separate editor will appear where you can enter the sample comment. The editor will be 

sized to the width of the screen. A carriage return will not result in a new line in the editor. A 

count of the characters available in the field is displayed in the upper right corner. The position 

of the cursor is displayed in the lower right corner. After entering the sample comment, type 

“CTRL-e” to save and exit the editor. If a sample comment item has already been entered, a “Y” 

appears after the “:” and the “Add?” query will appear as “Edit?”. If you choose to edit the 

existing comment by putting a “Y” after the “Edit?” query, then the comment is displayed in a 

separate editor and options are presented for edit, delete, retain, or cancel. Note: You may not 

enter comments directly in the login screen. If you enter anything other than a “Y” or “y” 

after the “Add?” or “Edit?” queries, the entry will not be accepted, and no change will be 

made to the comment field.

(21) The Collecting Agency is a field used to identify the code for the agency that collected the 

sample. You can display valid collecting agency codes by typing a “?” followed by a carriage 

return. Note: the result will be a long list of collecting agency codes and agency names, listed 

alphabetically by the code. To reduce the list, you can type in a question mark “?” followed 

by a partial name or a complete name, and all matches based on the short collecting agency 

code or agency name would be shown on the screen. For example, if you type “?WRD” then

any collecting agency with the word “WRD” in the collecting agency code or name would 

appear in the list shown on the screen. For this example, this entry would appear, “USGS-WRD

QWDATA: Section 3.1 Option 1 – Login Samples

Water Quality 47 NWIS User

A default value for the collection agency field can be set in the 

/usr/local/nwis/data/auxdata/qw.conf file. For details about how to use the qw.conf file, see 

Section 3.8. Valid collecting agency codes are in Appendix K, “Protocol Organization Codes.” 

Some protocol organization codes cannot be used for new data entry; the program will notify you

if the selected code is not valid for new data entry and a different code is needed.

After completing entry of the collecting agency code, you are prompted with an option to make 

changes to any of the previously entered items on the login sample screen. If any of the valid 

item numbers are entered, the cursor is repositioned at the selected item. Changes made to any 

entry are subject to the same edit criteria as during initial entry. A carriage return after the last 

item or a “/q” allows you to complete the login sample form.

Following completion of the sample-header information, the database is searched to ensure that 

the header information is new. The header information is a combination of the agency code, 

station number, medium code, dates, and times. If a record with the same header information is 

found, the entry is rejected with the following error message.

• That RECORD already EXISTS – RECORD NUMBER ######## 

• Re-enter(Y/N)? 

On completion of the login form, the next screen asks: 

• Do you want to enter any data for this record (Y/N)? 

If you respond with an “N” this step is skipped. If you respond with a “Y,” the following query 

appears.

• Are you entering lab (L) or field (F) data? (L or F, <CR>=F): 

If you choose “F” the field data entry screen is the same as described in Section 3.2.1.

If you choose “L” the laboratory data entry screen is the same as described in Section 3.2.2. 

After entering or not entering data, a record is created and the assigned record number is 

displayed. Many users write the record number on the National Water Quality Laboratory 

Analytical Services Request Form or water-quality field notes.

previous sample and entered a comment for the sample, then you are given an opportunity to 

retain or edit the sample comment on the next screen, where the previous sample information is 

redisplayed with prompts for the item numbers you wish to change.

The ability to edit the previous sample information allows for the rapid login (data entry) of 

samples with mostly repetitious information (e.g., samples at the same site that differ only by 

time, such as vertical measurements in a lake). An “N” causes a new input form to be displayed 

(without the previously entered values). The dialog proceeds as before, with the cursor 

positioned at the “U” in “USGS” of the agency code. A maximum of 500 parameters can be 

stored in a single QWDATA file record.

3.2 Option 2 – Modify Samples or Results

Option 2 of the main QWDATA menu has three options that can be used to modify samples or 

results through the submenus. The first option, “Enter Field Results,” is a program used to add 

field water-quality data to existing records in the QWDATA database. The second option, “Enter 

Laboratory Results,” can be used to add laboratory data to QWDATA. The third option, “Edit 

Samples or Results,” can be used to edit existing header information or results.

Note: A record must exist in the database before any of these programs can be used. The record 

number or agency, site number, date, time, and medium code must be known before any of these 

programs can be used. The program for logging in a sample is described in Section 3.1.

Example of the field-results data entry format (shaded values are mandatory).

The program begins at the first parameter with the cursor at the method “Meth” field. The 

options for moving around the screen from parameter to parameter and screen to screen are 

displayed at the bottom of the screen. They are also described in Section 2.2.2 and can be listed 

on the screen by typing the options “?/”. A description of each item in the field-data entry form 

follows. 

Meth: The method code is not a mandatory field for the result value, but the method code is 

validated when entered or edited. General information on the method code is in Section 2.5.6, 

and you can list method codes for a parameter on the screen by typing a “?” in the “Meth” field. 

Some method codes are not valid for new data entry, and a warning message will be displayed 

onscreen if one is chosen.

In QWDATA 4.6, analysis method codes were expanded from a one-character to a five-character 

alphanumeric code. Method codes can be displayed using the Support Files menu Option 8--

Display the Parameter Method Table, (see Section 3.6.8). If the method code is changed for a 

result, the following message will appear on the screen.
QWDATA: Section 3.2 Option 2 – Modify Samples or Results

Water Quality 52 NWIS User

You have changed the method code for an existing record.

Your options are: 

 1: Replace result_rd with selection from PMT

 2: Enter a new rounding code 

 3: Keep the existing result_rd

Enter 1, 2, or 3 (<CR>=1): 

This message is related to the link between the method code and the rounding behavior for that 

result. Option 1 (default) will change the rounding code for that result to the value derived from 

the parameter-method table. Option 2 allows you to enter any rounding code for that result. 

Option 3 will result in the rounding code remaining the same as it was prior to changing the 

method code. 

V: The value for the individual parameter. A decimal point at the end of the value is assumed for 

values entered without a decimal point. You must enter the decimal point for values that are not 

whole numbers. A carriage return with no data is interpreted as no data, and that parameter is not 

stored. Entering a “#” signifies a null value, and you are required to qualify the null value with a 

null-value remark code or null-value qualifier code. If a value exists for a parameter in the field 

form, entering a carriage return retains the existing value, entering a new value replaces the 

existing value, and entering “/d” causes the parameter to be deleted from the record. The “V” 

field can accommodate scientific notation.

Rd: The rounding precision is used to display the data. Rounding is described in Section 2.7.1. 

Note: Due to a nine-character field width restriction, the program is unable to display values with 

nine or more digits.

Rmk: Remark codes are used to qualify data values, as well as null values. Remark codes are 

listed in Appendix A, Table 6, described in Section 2.5.1, and can be listed on the screen by 

typing a “?” after the “Rmk” prompt.

DQI: The data quality indicator code is a mandatory entry for the result that indicates the review 

status of the result, controls whether the batch-update programs can overwrite the result, and 

affects whether the result will be included in retrievals. Valid DQI codes and meanings are listed 

in Appendix A, Table 9, described in Section 2.5.3, and can be listed on the screen by typing a 

"?" after the DQI prompt. 
QWDATA: Section 3.2 Option 2 – Modify Samples or Results

Water Quality 53 NWIS User

Null Qual: If the parameter value is entered as a null value, a null-value remark or a null-value 

qualifier is required. The valid null-value remarks and null-value qualifier codes are listed in 

Appendix A, Table 10 and described in Section 2.5.4. 

Val Qual Codes: The value qualifiers provide additional information about the result values, 

which may be used for interpretation and archival of the results. QWDATA can store as many as 

three value qualifiers for each result from the valid codes listed in Appendix A, Table 11, 

described in Section 2.5.2, and can be listed on the screen by typing a “?” after the Val Qual 

Codes prompt. 

Anl Ent: The analyzing entity is an optional field that identifies the agency, organization, group 

or company that analyzes the result, which can be added, changed, or deleted. You can display 

all analyzing entity codes by typing a “?,” followed by a carriage return. Note: the result will be 

a long list of analyzing entity codes and names, listed alphabetically by the code. To reduce 

the list, type in a question mark and a partial name or a complete name as input, and all matches 

based on the short analyzing entity code or name will be shown on the screen. For example, if 

you type “?NWQL,” then any analyzing entity with the word “NWQL” in analyzing entity code 

or name would appear in the list shown on the screen. For this example, this entry would appear 

“USGSNWQL – U.S. Geological Survey, National Water-Quality Laboratory, Denver, 

Colorado.” All analyzing entity codes can be found in Appendix K, “Protocol Organization 

Codes,” and they are described in Section 2.5.10. Some protocol organization codes cannot be 

used for new data entry; the program will notify the user if the selected code is not valid for new 

data entry and a different code is needed.

Result field comment: Result comments are used to describe any information that the user 

might want to associate with the result value. For example, if the pH meter could not be 

calibrated with buffer solutions and the pH value was suspect, that information could be stored 

with the pH value and other parameters, such as alkalinity and bicarbonate, which were 

measured using the same pH meter. A description of comment fields is included in Section 2.8. 

If you have not entered a result comment, an “N” appears after the “Add?” field. If you enter a 

“Y” and a carriage return, a separate editor will appear. The editor will be sized according to the 

width of the screen. A carriage return will not result in a new line in the editor. A count of the 

characters available in the field is displayed in the upper right corner. The position of the cursor 

is displayed in the lower right corner. Control “c” cancels the comment entry and control “e”

saves the comment and exits. You then receive the following prompt. 

Do you want to apply the comment to other parameters (Y/N)? 

If there is an existing comment, this result field comment will be appended to it.

If you answer “Y,” a new screen is displayed with four options. 

1. Enter additional parameter codes at the terminal, where you enter the parameter codes one 

at a time and use a carriage return to end the program. This brings you back to the field data 

entry form. The comment can be applied to as many as 500 parameter codes.
QWDATA: Section 3.2 Option 2 – Modify Samples or Results

Water Quality 54 NWIS User

2. Apply the comment to parameters contained in a file; enter the pathname of the file at the 

prompt. 

3. Update all parameters in a sample with the comment.

4. Update all the parameters in the sample but confirm each before updating. 

If a result field comment exists, then a new screen with three options is displayed for editing an 

existing comment. 

1. Edit the comment, 

2. Delete the comment.

3. Cancel the editing process. 

If the comment is edited, the four options (listed above) to apply it to other parameters are made 

available. 

When data entry is complete, you can exit the program by either using “/q” or inserting a 

carriage return after the last parameter in the form. The program provides an opportunity to 

modify the data by displaying the prompt: 

Changes? Enter item number to change or <CR> to continue. 

You can add additional parameters may to the sample without having to add them to the 

field.parmsnn file by entering “/a” at any time. A screen prompt will ask for numeric entry of 

the desired five-digit parameter code, which will be checked against the parameter entry flag in 

the Parameter Method Table (Section 3.6.8) to determine if the parameter is valid for entry. 

Some parameters are no longer valid for new data. If it is valid, the parameter appears at the next 

line, and the cursor is positioned to accept a value. 

As you enter each value, the following checks are made.

1. If the value is negative, the parameter code is checked against a list of codes for which 

negative values are permitted.

2. If the entry is invalid, a message is displayed and the value is rejected. Negative Values 

are described in Section 2.7.3 and listed in Appendix H. 

3. If the value is for a parameter that should contain fixed values, the fixed values file list is 

checked; if the value is invalid for that parameter, a message is displayed and the value is 

rejected. Fixed values are listed in Appendix B and described in Section 2.6.3. 

4. If the value for pH (parameter code 00400) is greater than 14, a message is displayed and 

the value is rejected. If the value for pH is outside the range of 4.5 to 9.0, a message will 

be displayed during data entry, but the value will be retained. 

When data entry is complete, the record is stored and the dialog restarted with the request for a 

record number or “Q” to end. You will need to run the Chemical Validation Checks program 

described in Section 3.3.5 to validate updates. General information about chemical validation 

checks is described in Section 2.9.2.

3.2.2 Option 2 – Enter Laboratory Results

The “Enter Laboratory Results” program is used to interactively enter and edit data from 

cooperator laboratories or USGS laboratory data that are not loaded into QWDATA from other 

programs. (The batch loading program for QWDATA is described in Section 3.8). Laboratory 

data values can be entered into QWDATA with this program as well as in the “Login Sample” 

program described in Section 3.1, and the “Enter Field Results” program described in Section 

3.2.1. 

The “Enter Laboratory Results” program uses a field form, which is a list of parameter codes and 

associated information in a file named field.parmsnn , stored in the directory 

/usr/local/nwis/data/auxdata/qw_field_forms/ , where “nn” represents the two-digit form 

number. Information about adding and designing a field form is available in Section 2.10 and Tip 

Sheet 5.3. 

After selecting Option 2, you are prompted to enter the record number for the sample or a 

carriage return to identify a sample by agency code, station number, start date, start time, end 

date, end time, and medium code. The record number and sample information are displayed and 

you are asked if this is the desired record. 

If this is not the desired record, or the record is not found in the database, you are given another 

opportunity to enter a record number or agency code, station number, dates, times, and medium 

code. To quit from this application, enter a “Q” in place of the record number. After the desired 

sample is displayed and accepted by typing a “Y” or a carriage return, you are prompted to enter 

a field form number. 

List available field forms to the screen by typing a “?” and carriage return. You can display 

detailed contents of the field form by entering “?#”, where “#” is the number of the field form. 

After the number of the desired field form has been identified and entered, followed by a 

carriage return, the program displays the parameter codes and names from the requested field 

form, with spaces for the entry of values and attributes. If the sample already contains data for 

any of the specified parameters, the stored values are displayed as shown below.

valid for new data entry and a different code is needed.

Result field comment: Result field comments are used to describe any field information that 

you might want to associate with the result value. For example, if the pH meter could not be 

calibrated with buffer solutions and the pH value was suspect, that information could be stored 

with the pH value and other parameters, such as alkalinity and bicarbonate, which were 

measured using the same pH meter. Description of comment fields is in Section 2.8. 

If you have not entered a result comment, an “N” appears after the “Add?” field. If you enter a 

“Y” and a carriage return, a separate editor will appear. The editor will be sized to the width of 

the screen. A carriage return will not result in a new line in the editor. A count of the characters 

available in the field is displayed in the upper right corner. The position of the cursor is displayed 

in the lower right corner. Control “C” cancels the comment entry and control “E” saves the 

comment, exits, and then prompts: 

Do you want to apply the comment to other parameters (Y/N)? 

If you answer “Y,” a new screen is displayed with four options. 

1. Enter additional parameter codes at the terminal, and type in the parameter codes one at a 

time. A carriage return ends the program, bringing you back to the field data entry form. 

You can apply the comment to as many as 500 parameter codes. 

2. Apply the comment to parameters contained in a file; the pathname of the file is entered 

at the prompt. 

3. Update all parameters in a sample with the comment.

4. Update all the parameters in the sample, but confirm each before updating. 

If a result filed comment exists, then a new screen with three options is displayed for editing an 

existing comment. 

1. Edit the comment.

2. Delete the comment.

3. Cancel the editing process.

Result lab comment: Result lab comments are used to describe any laboratory information that 

might be associated with the value. The prompts and screens are the same as the “Results field 

comment,” which is described above. Text fields for comments are described in Section 2.8.

When data entry is completed, you can exit the program by either using “/q” or inserting a 

carriage return after the last parameter in the form. The program provides an opportunity to 

modify the data by displaying the prompt: 

Changes? Enter item number to change or <CR> to continue: 

You can add additional parameters to the sample without having to add them to the 

field.parmsnn file by entering “/a” at any time. A screen-prompt will ask for numeric entry of 

the desired five-digit parameter code, which will be checked against the parameter entry flag in 

the Parameter Method Table (Section 3.6.8) to determine if the parameter is valid for entry. 

Some parameters are no longer valid for new data. If it is valid, the parameter appears at the next 

line, and the cursor is positioned to accept a value.

As each value is entered, the following checks are made:

1. If the value is negative, the parameter code is checked against a list of codes for which 

negative values are permitted; if the entry is invalid, a message is displayed and the value 

is rejected. Negative Values are described in Section 2.7.3 and listed in Appendix H.

2. If the value is for a parameter that should contain fixed values, the fixed values file list is 

checked; if the value is invalid for that parameter, a message is displayed and the value is 

rejected. Fixed values are listed in Appendix B and described in Section 2.6.3. 

3. If the value for pH (parameter code 00400) is greater than 14, a message is displayed and 

the value is rejected. If the value for pH is outside the range of 4.5 to 9.0, a message will 

be displayed during data entry, but the value will be retained. 

When data entry is complete, the record is stored and the dialog restarted with the request for a 

record number or “Q” to end. You will need to run the Chemical Validation Checks program 

described in Section 3.3.5 (Option 5 of Function 3, Data Review) to validate updates. General 

information about chemical validation checks is described in Section 2.9.2. 

3.2.3 Option 3 – Edit Samples or Results

The “Edit Samples or Results” program is used to modify the record header information for a 

sample, to modify the analytical results for a sample by adding, changing, or deleting parameter 

values or attributes, or to delete a sample record. 

After selecting Option 3, you are prompted to enter the record number for the sample, or a 

carriage return to identify a sample by agency code, station number, start date, start time, end 

date, end time, and medium code. The record number and sample information are displayed, and 

you are asked if this is the desired record. 

If this is not the desired record, or if the record is not found in the database, you are given 

another opportunity to enter either a record number or the agency code, station number, dates, 

times, and medium code. To quit from this application, enter a “Q” in place of the record 

number. After the desired sample is displayed and accepted by typing a “Y” or a carriage return, 

the following screen is displayed:

This option is used to create three types of files; (1) lists of sites that meet user-specified site 

selection criteria, (2) lists of sites that have water-quality data that meet user-specified site 

selection and sample selection criteria, and (3) lists of record numbers for water-quality data that 

meet user-specified sample selection criteria. These files may be used as input to other options in 

the NWIS-QWDATA system. The record number list file is required for Generating Output to 

Files (Section 3.4 – “Data Output”).

Sample selection is a two-step process. First, site numbers are specified using one of the first 

three options on the Select Sites or Samples submenu. By using Option 4, site selection is 

skipped—effectively selecting all sites in the database.

To be selected, a site record must satisfy all the selected criteria.

NOTE: These selection criteria are optional fields in the SITEFILE record. If the selected field has 

not been populated in a site record, that site will fail the selection criterion.
QWDATA: Section 3.3 Option 3 – Data Review Options

Water Quality 67 NWIS User

The speed of the SITEFILE retrieval will vary depending upon the amount of qualification by 

the selected criteria that you supplied. You will be given a warning and an opportunity to abort 

the SITEFILE search if the criteria are too general. If no site selection criteria are specified, the 

default condition is invoked and the selection criterion used is Agency code = USGS.

When the sort is complete or if the sort option is skipped, you will be prompted to enter a 

filename to hold the retrieved site numbers. The site numbers and associated location and other 

site information are saved in a file using a fixed-column format shown in Appendix C. 

If you choose not to specify site numbers in the Select Sites or Samples submenu, the program 

moves to the option to select water-quality records.

3.3.1.2 Selecting Water-Quality Records

After sites are selected, you may select water-quality records for the specified sites or you may 

return to the Data Review menu. To select water-quality records, a screen is displayed to specify 

selection criteria. If no water-quality record selection criteria are specified, by entering a <CR>

in the (1) DATE field, the program will use a default date range from 1776 to present—in effect, 

selecting all records in the database and a default sample analysis status code setting.

The default analysis status code (Appendix A) setting is determined by the types of databases

included in the retrieval. The default for an environmental database is to include all unrestricted 

samples; the default for quality-control databases is to include all unrestricted and internal-use 

samples. If a retrieval from multiple databases is made that includes both environmental and 

quality-control databases, then the default is all unrestricted and internal-use samples.

not being included in retrievals limited by date. The retrieval program will use the time variable 

set for the UNIX environment on the local computer system. To avoid missing samples in a date 

range, you could include an extra day on either end of the desired date range. The examples 

below demonstrate this behavior.

Screen for selecting water-quality records based on analysis status codes.

The default behavior is important to note for records retrieval. When querying QWDATA from 

an environmental database (typically numbered “01”), the program will include only records 

where analysis status is set to “U – unrestricted.” If you are searching for records from a QC 

database, the program will search for records of analysis status of either “U” or “I –internal-use 

only.” The only means of searching for proprietary samples from this menu option is to include 

records where analysis status = “P.” The default behavior will be followed unless you select 

different options at this menu. 

You will be notified that the database search has begun. After water-quality records are retrieved 

(and if the number of records retrieved are greater than zero), the number of records and the 

number of sites are displayed on the screen. Note the message line that indicates which analysisstatus codes are being excluded:

The user is notified of the number of water-quality records retrieved, 

which analysis status code types are excluded, and the number of sites 

for those records. The user is given the option to save a list of sites for 

which water-quality records were selected.

Users with read-only access to the database table being queried will not be able to locate records 

with an analysis status = “I”’ or “P.” 

If you specified a selection based on (4) PROJECT ID, then you will have an opportunity to 

enter up to 10 project-ID searches. The search text may use an asterisk (“*”) as a wildcard for 

matching multiple project identifiers. For example, the search text “4630148*” will retrieve any 

sample where the stored project identifier begins with these seven digits. Any lower-case letters 

in the search text are automatically converted to upper case before the search begins. Thus, this 

search criterion will not find samples with project identifiers stored with lower-case letters.

You may select more than one parameter code. Selection by parameter codes and values is the 

only selection that does not require that the specified criteria must be satisfied to qualify a waterquality record for selection. If you specify more than one parameter code, then for each 

parameter after the first, you will be asked whether the relation to the previous parameter is 

“AND” or “OR.” The “AND” or “OR” option in combination with the “NOT” option results in 

specific actions based on the rules of Boolean logic (Section 2.2.6 – Getting Started). Examples 

are shown in the table below.

3.3.2 Option 2 – Select Sites and Samples from Multiple Databases

Water-quality data from as many as five databases may be retrieved, as shown on the following 

screen. The multiple database retrieval option is most often used when data must be retrieved 

from the environmental database and the quality-assurance database. You may enter database 

numbers in any order. After the desired database numbers are entered, the user input is the same 

as that described in Section 3.3.1. The output to the screen informs you of the results of 

selections for each database that you had specified.

3.3.3 Option 3 – Produce Inventory of Samples

This option is used to produce a table of information for records that have been logged into the 

database for samples collected within a specific water year. This program has historically been 

identified as the “loglist” program. The table may be limited to a user-supplied list of up to 50 

station numbers, or a range of dates within the specified water year, or both. An example of the 

output from this program is included in Appendix C. This tabular output is written to a file, 

which you may print. Included in this output is information on the total number of parameters 

and the number of analyses in each parameter-sequence group. The parameter-sequence group 

codes, short names, and descriptions are listed in Appendix N. The number of parameters in each 

group includes only stored parameters. Calculated parameters or those accessed from the 

SITEFILE, ADAPS, or GWSI are not included in the parameter count. 

You will first be queried for the name of a file to hold the output. The filename may include the 

pathname if you do not wish to save the file in the current directory. If the specified file already 

exists, it may be either appended or overwritten, according to your response. Enter the water year 

next. Within the selected water year, the table may be restricted to specific station numbers and a 

range of dates. Station numbers may be entered interactively or from a fixed-column format file. 

Station numbers also are accepted in the format used to output stations under menu Option 3.3.1.

Sites also may be input interactively without an agency code.

of station numbers, or date range, or both. If you respond “NO,” you will be returned to the Data 

Review menu.

3.3.4 Option 4 – List Samples and Results

Sample information and analytical results for requested records can be displayed to the screen or 

a file. Records may be identified by record number or by agency, station number, date, time, and 

medium code. You will first be given the option to enter record selection information 

interactively or to input this information using an existing file. Note: The minimum identifying 

information needed to uniquely identify a sample is agency code, station number, date, and 

medium code.

To retrieve a record using sample identification information, all information that has been 

entered for a particular sample must be specified. The fields that could be completed are agency, 

station number, date, medium code, time, end date, and end time. For example, if all of these 

fields were populated for a particular sample, then all of the fields must be used to identify and 

retrieve the sample. Typically, samples are uniquely identified with agency code, station number, 

date, time, and medium code. 

If the list of records is to be entered from a file, you will be prompted for the filename and input 

format of either 1 for Record Number, or 2 for Agency Code, Station Number, Date, Time, 

and Medium Code.

option. Example output files are shown in Appendix C. 

1. List All Parameters and Results: If you choose to output all parameters and results, all 

results for the sample are written in the same format as the WATLIST report as shown in 

Appendix C. 

2. Create Cation/Anion Balance Table: If you choose to output a cation-anion balance table, 

there will be an option to create an output file containing the ion balance results. If you request 

such an output file, a tab-delimited “rdb” style file is created. An example output file is shown in 

Appendix C. A reference table defines the parameter codes that are used in all programs that 

produce an ion balance table (WATLIST, qwvalid, qwbal). This reference table includes: the 

parameter code; a flag indicating if the parameter is calculated; a multiplication factor to convert 

the result units to milliequivalents per liter units; the ion type (cation or anion); the group that the 

parameter belongs to (e.g., alkalinity, nitrogen species); a flag indicating if the parameter is a 

major ion, the hierarchy of similar parameters within a group (e.g., if multiple alkalinity 

parameters are present, which is used in the calculation); and the order of the ions in the table 

output. This table may be updated quarterly. A listing of these parameters is shown in Appendix 

L. 

You may request a customized ion balance calculation by specifying a user-specified table and 

by supplying a custom ion balance specifications file. This is the only program in QWDATA that 

allows users to customize the ion balance. This file gives the software explicit instructions on 

how to calculate the table, which parameters are considered cations or anions, what 

multiplication factor should be used, what order the parameters are to be included in the output, 

and the hierarchy of parameters within the same group. The format for this file is shown in 

Appendix C. You may create your own file or may modify the standard ion balance 

specifications file produced in “Data Review” Option 6 described in Section 3.3.6.

An example of output from this program is shown in Appendix C. Analytical results are included 

in this output and are unrounded. Cation and anion values are shown unrounded for the original 

parameter units; values calculated as milliequivalents per liter are rounded to 3 digits after the 

decimal in the output table and tab-delimited output files. Calculations of cation sum, anion sum, 

and percent difference are made using unrounded results. Results that have remark codes may be 

included in the cation-anion balance table and these codes may affect how the ion balance is 

computed, as shown in the following table.

3. Perform Chemical Logic Checks: Chemical logic checks are performed for specific samples 

when this option is selected. The chemical logic checks include the checks performed when 
QWDATA: Section 3.3 Option 3 – Data Review Options

Water Quality 86 NWIS User

batch processing programs are used and the results are printed in the WATLIST file (example in 

Appendix C). A detailed listing of the chemical validation checks in QWDATA is listed in 

Appendix M. In general these checks include: 

• Field measurement results against general guidelines; 

• Chemical logic; 

• Bacterial logic; 

• Comparisons between stored calculated parameters and current calculated values; 

• Both values are first rounded using default rounding as described in Section 3.4.3.4; 

• Comparisons between related constituents; 

• Comparisons between unfiltered and filtered constituents, 

• Comparisons between selected constituents and individual parameters that make up the 

sum of parts; 

• Comparisons of constituents to alert limits in Appendix E; and

• Calculation of a cation/anion balance.

• In NWIS 4.6, an option to specify the parameters used in calculating the 

cation/anion balance was added. This option is described in more detail in Section 

3.3.6. 

4. List Results that Exceed EPA Drinking Water Limits: Results for specific samples are 

compared automatically to the U.S. Environmental Protection Agency (EPA) Primary 

Drinking Water Maximum Contaminant Levels and Secondary Maximum Contaminant Levels 

when this option is selected. Results with remark codes of “E,” “A,” “S,” “V,” or “>” are 

allowed. The EPA Drinking Water Limits are listed in Appendix E. A warning message, which 

includes the parameter code, parameter short name, remark code, result, units, and alert limit is 

written for results that exceed the limit (example in Appendix C). The comparisons include the 

comparisons performed when batch processing programs are used and the results are printed in 

the WATLIST file (example in Appendix C).

5. List Results that Exceed User-Specified Limits: The data review and batch-processing 

programs automatically compare selected result values to the U.S. Environmental Protection 

Agency (EPA) Primary Drinking Water Maximum Contaminant levels and Secondary Maximum 

Contaminant Levels; however, users also may have the need to compare results to other Federal, 

State, and local regulatory standards for waters used for specific purposes. User-specified alert 

limit forms are used by data review and batch-processing programs in QWDATA to provide the 

user with the option to compare results to these other Federal, State, and local regulatory 

standards. 

You may add new user-specified alert limit forms to be used in QWDATA by creating a form 

using a specific format and storing it in the /usr/opt/nwis/data/auxdata/qw_alert_limits directory. 

Alert limit form names are in the format alert.limitnn where “nn” is the 2-digit number that 
QWDATA: Section 3.3 Option 3 – Data Review Options

Water Quality 87 NWIS User

identifies the form. Instructions for creating the user-specified alert limit form are found in 

Section 2.9.2.1.1, and an example of the form is shown in Appendix G. You should create new 

user-specified alert limit forms if none of the available alert limit forms fit the data to be entered. 

Review available user-specified alert limit forms prior to creating a new form so that duplication 

of user-specified alert limit forms is avoided.

Selected result values are compared to the user-specified alert limits when you select this option. 

You have the option to select one or more user-specified alert limit file number(s), or you may 

specify “all” to use all available files.

Enter alert limit file number(s), comma separated, or "all" to use 

all available files: (q to quit, ? to search, <CR>=none) 

A warning message, which includes the parameter code, parameter short name, remark code, 

result, units, and alert limit, is written for results that exceed the user-specified limit (example in 

Appendix C).

6. Perform Data Validation Checks: Data validation checks are performed for specific samples 

when this option is selected. The data validation checks include the checks performed when 

batch processing programs are used, and the results are printed in the WATLIST file (example in 

Appendix C). A detailed listing of the data validation checks in QWDATA is given in Appendix 

M. In general, these checks include: 

• Station number does not exist in the SITEFILE, 

• Invalid geologic-unit code, 

• Invalid sample type, analysis status, hydrologic condition, or hydrologic event codes, 

• Sample-preparation or sample-analysis date prior to sample-end date,

• Fixed-value parameter is incompatible with measurement-parameter attributes, such as 

remark code,

• Invalid fixed-value parameter value.

• A null-value remark code accompanies a non-null result value, and 

• Invalid method code.

3.3.6.1 Dump Standard Ion Balance Specification File

This option will provide a standard ion balance specifications file that you can be modify to 

create a custom ion balance specifications file, because both types of files use the identical 

format. It can also serve as a reference for the ion balance calculations within QWDATA. You 

may use the first line of the specifications file for a user-specified title for the output. You may 

also insert comments into any part of the file by entering a “#” in column 1 of the comment line. 

You have full control over how the custom ion balance table is calculated, including the 

precedence order in which parameters are used in the calculation. For example, if multiple 

parameter codes for chloride are included in the file, you must specify which codes should be 

used. A detailed description of the specifications file is in Appendix C.

3.4 Option 4 – Data Output 

Option 4 of the main menu accesses a submenu with options to output data (1) in tables for 

publication in reports, (2) in files that can be loaded into other applications, and (3) in files that 

can be used for the P-STAT statistical package. Tables for publication and files that can be 

loaded into other applications can be retrieved in two formats: by sample or by result. Additional 

information about tabling options can be found in Section 2 –Getting Started. To retrieve any of 

these output formats, a file of record numbers is required, and it can be produced using Option 1 

or 2 from the Data Output menu.

See description in Section 3.3.1. 

3.4.2 Option 2 – Select Sites or Samples from Multiple Databases

See description in Section 3.3.2. 

3.4.3 Option 3 – Water-Quality Table by Sample (Publication Format)

This option was used to prepare tables of water-quality data in the historical format required by 

the USGS for publication in the Water Science Center (WSC) Annual Data Report (ADR). 

Output for the ADR is now produced using Option 7 –Flat File with TAB delimiter (Publication 

Export), Section 3.4.7. The four table types described below are available with Option 3 as well 

as with Option 4 – “Water Quality Table by Result.”

1. Single-station format: Data for each station are tabled separately so that each new 

station starts at the top of a page. Currently this is the only format for surface waterquality data published with streamflow gage record in the WSC ADR.

2. Miscellaneous-station format: Data for all stations are tabled together. Each new set of 

parameters begins at the top of a page. Station numbers, names, and latitude/longitude are 

printed on a single line that precedes the data for that station. This is the most commonly 

used format for publishing miscellaneous records of surface-water quality.

3. Multiple-station format: Data for all stations are tabled together in sequence just as for 

the miscellaneous-station format. Station numbers and dates, if requested, are printed in 

the first columns of the table. This is the most commonly used format for miscellaneous 

groundwater data. 

4. Biologic data format: Data for each station are tabled separately so that each new station 

starts at the top of a page. For each sample, the output tabulates the taxonomic biological 

identification, counts, and percentage of population. This format was developed for and 

used to display data produced during the 1970s and early 1980s by the biologic section of 

the Atlanta Central Laboratory. 

3.4.3.1 Specify the Sample Records for Tabling

After selecting Option 3, you will be asked to provide the name of the file that contains the list of 

record numbers to be tabled. This list is usually generated by the “Select Sites or Samples” 

(Section 3.3.1) option or the “Select Sites or Samples from multiple databases” (Section 3.4.2)

option. A list also may be created by using an editor; the format for this type of input file is 

shown in Appendix G. Beginning in column 1, enter each eight-digit record number on a separate 

line. If the records are from multiple databases, the database number is a two-digit number in 

columns 9–10. After identifying and opening the input file, provide the name of a file that will 

contain the output table. If the specified output file already exists, you may replace the data in 

the file (overwrite), leave the file intact and add the new table to the end of the file (append), or 

type in a new filename.

That file already exists

Do you wish to re-use that file (Y/N)? y

Do you wish to over-write or append (O/A)?

You will be prompted to provide the name of a 

file that will contain the output table.

3.4.3.2 Specify the Table Definition

Assemble a “table definition” by selecting a table type and specifying output options. The table 

definition sets up the specification parameters that determine the table format. Enter the table 

definition either from an existing table definition file or by answering several queries. If you 

enter “Yes,” you are prompted to enter the file pathname. If the specified table definition file 

exists, the table definition is retrieved and displayed. You will be asked if this is the desired 

definition and, if so, if are changes to be made to the definition. 

If no existing definition is to be used, the following screen is displayed: 

TABLE TYPE (1,2,3,OR 4): 

DELETE COLUMN IF NO DATA (Y OR N): Y PRINT PARAMETER CODES (Y OR N): Y

LINES PER PAGE: 90 FOLDING OPTIONS (0,1,2,OR 3): _

Water Quality 93 NWIS User

If you are uncertain about the meaning of a field on the screen, entering a question mark (?) will 

produce an explanation of the field and the effect of each option to be displayed; the cursor then 

returns to the same field for entry of the option value. 

TABLE FORMAT (MANDATORY):

OPTIONS: 

1 -- Single Station.

2 -- Miscellaneous Station. 

3 -- Multiple-Station. 

4 -- Biologic Data. 

PLEASE ENTER 1, 2, 3, OR 4: 

When a "?" is entered in the table type field, a list of field 

options is displayed to the screen.

After you enter the table type code, default options are placed after the colon (:) in each 

succeeding field. Enter a carriage return to accept the default value.

• TABLE TYPE (1,2,3, OR 4) : Examples of each table type are found in Appendix C.

• DELETE COLUMN IF NO DATA (Y OR N): Y If none of the selected samples 

contain a result for one of the requested parameters, the columns associated with that 

parameter will be removed entirely unless you enter an “N” here. In that case, the column 

headings will be retained and the no-value indicator of “—“will be printed for each 

analysis. 

• PRINT PARAMETER CODES (Y OR N): Y Parameter codes will be included with 

the parameter name in the column headings unless you enter an “N.” 

• LINES PER PAGE: 90 This determines the number of lines printed per page of output. 

The default page length of 90 lines produces a page with the proper proportions for 

reduction to the standard WSC ADR page size. To modify the 90 lines per page, enter the 

appropriate number of lines, left justified. 

• FOLDING OPTIONS (0,1,2,OR 3) 

0 No folding, applicable to all table types 

1 Horizontal folding, 24–100 parameters per page, applicable to type 1 tables only 

2 Horizontal folding (obsolete, same as Option 1) 

3 Vertical folding, maximum of five parameters (including date), applicable to type

1 and type 2 tables only 

• REMOVE HEADING LINE (Y or N): N The top line of the table will include a 

heading line with the WSC code, “United States Department of Interior - Geological 

Survey,” and processing date unless a “Y” is entered here.

Each table type results in a different list of formatting options. Additional fields may appear as 

options, depending on the table type selected. 

If you select table type 1 (single-station format), two additional fields, REPORTING YEAR

and TABLE TITLE are added to the screen. 

• REPORTING YEAR (W=WATER,C=CALENDAR,BLANK=NO BREAK): Allows you 

to specify if pages should break with new headings or be suppressed at changes in the 

water year or calendar year. A <CR> enters the default (blank) and suppresses a page 

break.

• TABLE TITLE: Allows you to select any of the following 13 standard titles to be placed 

on each page of the table.

After the table definition has been defined for table type 1, processing passes to the next step—

storing the table definition. 

When you select table type 2 (miscellaneous-station format), available fields are the same as for 

a type 1 table, and processing passes to the next step of storing the table definition. 

When you select table type 3 (multiple-station format), seven additional fields are added to the 

table definition screen shown for a type 1 and type 2 table. 

• COUNTY SKIP OPTION: 

0 No skip; table is not sorted by county (default). 

L Sort by county; place three blank lines between counties; do not print 

county name.

P Sort by county; place a page break between counties; do not print county name. 

Q Sort by county; place three blank lines between counties; print county name. 

R Sort by county; place a page break between counties; print county name. 

NOTE: The alpha parameter code “CNTYC” must be included in the parameter list to use this 

option. If CNTYC is the last parameter in the list, county codes are used but not included in the 

table. If one of the skip options is invoked and CNTYC is not in the parameter list, it is added as 

the last parameter in the parameter code list. 

• LEFT-ADJUST LOCAL ID (Y OR N): N This is applicable only if you include the 

alpha parameter LOCAL in the parameter list; the local identifier (usually the well 

number) may be left justified under the column heading (Y) or printed verbatim with any 

blanks that may be included in the SITEFILE retained (N). 

• PRINT DATES (Y OR N): Y A column containing sample dates is printed unless you 

enter “N.” If the alpha parameter DATES is not included in the parameter list, it is added 

automatically after the last alpha parameter. If you select Option 1 for “Data for 

continuing pages,” this setting will be ignored. 

• CENTER STATION ID (Y OR N): N This option affects the alpha parameters STAID

(station identification number) and “SNAME” (station name). These values may be 

centered under their column headings (Y) or printed exactly as they are found in the 

SITEFILE, retaining any blanks (N).

• REPEAT DUPLICATE ID'S (Y OR N): N Values for sample identifiers STAID 

(station identification number), LOCAL (local station identifier), and/or LATLG 

(latitude-longitude) are printed for only the first line in a group of samples with the same 

ID. Samples must be sorted on one of these fields. These values may be printed for every 

sample by entering “Y.” 

• SKIP A LINE ON CHANGE OF STATION (Y OR N): N A blank line is inserted 

between every five analyses, regardless of station number. Enter “Y” to also insert a 

blank line between each new station number. This option is valid only if the record 

numbers are sorted by the alpha parameter STAID (station identification number).

After the table definition for table type 1, 2, 3, or 4 is completed, you may make changes to the 

definition. To do so, position the cursor on the first field after “TABLE TYPE.” You may enter a 

<CR> in fields that do not need to be changed and may retype the entry for fields that do need to 

be changed. This loop is continued until you are satisfied with the table definition and respond 

with a “No” or “N” when prompted to change the table definition. You may save the table 

definition for reuse on another table retrieval.

3.4.3.3 Specify Parameter Codes for Tabling

Parameter codes for output may be input from a file of parameter codes in a specific format 

Appendix G, or may be entered interactively. A maximum of 1,000 parameters may be included 

in a table. The number of requested parameters may need to be reduced slightly when required 

parameters are automatically included by the tabling software and the 1,000 parameter code limit 

is exceeded. For single-station format only, composites that span the end of a month are 

permitted and are printed with the proper dates. 

Next you are prompted to enter parameter codes for tabling. 

Select one of the following options to identify the columns in the 

table (parameter codes are used to identify columns): 

 1 -- Enter parameter codes at the terminal

 2 -- Enter a filename that contains a list of parameter codes

Enter option desired (1-2, or Q to quit): 
QWDATA Section 3.4 Option 4 – Data Output

Water Quality 98 NWIS User

If parameter codes are entered from the terminal, the following prompt appears.

Enter up to 1000 parameter codes:

(1) P: 00400 

(2) P: ________ 

Options: ? ^D # / /x /+x /-x /@ /c /q -- Enter ?/ for help

The next prompt is given the sequence number 2 and so forth until interactive entry is ended. 

End interactive parameter code entry by entering a carriage return <CR> for a parameter code. 

When interactive entry of parameter codes is completed, you are given the opportunity to make 

changes to any entry by entering the sequence number of the parameter code to be changed. 

Parameter codes are checked against the parameter code dictionary so that invalid parameter 

codes are rejected upon entry. If parameter codes 81024 (drainage area), 72000 (datum), or 

72008 (well depth) are included in the list of parameters and are not present in the water-quality 

record, they will be retrieved from the SITEFILE record. All numeric parameters contained in 

the parameter code dictionary are supported. Alpha parameter codes also may be tabled. A 

complete list of alpha parameter codes is available in Appendix A. 

During interactive session, a question mark entered for a parameter code allows you to display 

and search among all parameter codes with the same initial two digits, or to display the alpha 

parameter codes. If you enter a question mark, the software displays the following message. 

Need to qualify. Enter at least 2 lead chars of code (A for alpha parms):

Below are characteristics to remember about parameters used in publication table format.

• Parameters are placed in the table in publication order unless you choose to place them in 

the order they are supplied. If you select only one parameter to be included in the table, 

there is no option to place the parameters in publication order. 

• When the alpha parameter CALCV (include all possible calculated parameters) is 

specified in a by-sample format, all calculated parameters whose Group code identifies 

this subset (Section 3.6.7.2) are inserted at the point where the CALCV parameter was 

listed in ascending numeric order. 

• When the alpha parameter ADDPC is specified, all numeric parameters (including 

calculated parameters that have stored values) are printed in ascending numeric order. 

• When the alpha parameter ALPHA is specified, all possible alphabetic parameters are 

inserted at the point where indicated, and sorted alphabetically. See Appendix A for the 

few parameters not included; among them are ADDPC and CALCV. 
QWDATA Section 3.4 Option 4 – Data Output

Water Quality 99 NWIS User

• A maximum of 1,000 parameters may be included in a single table; the number of 

parameters may be reduced slightly when required parameters are automatically included 

by the tabling software.

• If an invalid numeric parameter is requested, an error message is written and the 

requested parameter is ignored.

• Date printing may be suppressed only for type 3 tables. If the alpha parameter DATES is 

not in the parameter list, it is automatically inserted as the first parameter.

• The vertical folding option is limited to five parameters (including DATES). If more than 

five parameters are listed when the vertical folding option has been specified, you will 

receive an error message and a parameter count. Parameters must be reentered from the 

terminal or reread from a file.

• Multiple occurrences of the same parameter are not permitted. If a parameter is entered 

more than once, the first occurrence is retained and the others are deleted from the list.

• When tabling records from multiple databases, the parameters MEDIM and DBNUM will 

be appended if not requested, for Output tables 3 and 4, Publication Styles only. 

• Parameters other than biological (taxonomic) parameters, and medium codes other than 

BH, BY, BE, BI, and BD will be omitted by the program for table type 4.

Enter item to change (1-12) or <CR> to continue: 

Screen with default specifications for specifying how 

parameter results will be printed in a table.

The default specifications are marked with an X as shown on the above screen. You can accept 

the default specifications by entering a <CR>. You can change each option by entering numbers 

1–12 to access one of the submenus described below. 

1. Limit Results by DQI Code:

This allows you to specify results that will be tabled according to the data quality 

indicator (DQI) associated with each result. By default, only results that are publicly 

accessible, or marked as historical, presumed satisfactory, or reviewed and accepted [DQI 

codes A, S, or R] will be tabled. By changing the default option, you may choose to 

include data that are in review, are reviewed and rejected, are from an unapproved 

laboratory or method, or are proprietary. Data that are marked proprietary shall not be 

published or made available to the public. If rejected results (DQI = Q or X) are included 

in water-quality table output, a “#” symbol will be included after (or behind) the value to 

indicate that the result has been rejected.

NOTE: If calculated values are included in the output, the DQI associated with the calculated value 

will be determined by the DQI’s of the parameters used in the calculation (Appendix D). The DQI for 

the calculated value will be applied from left to right in the following list:

X P O U Q I S A R

For example, if the parameters used in the calculated value had DQIs of P, S, and R, the 

calculated value would have a DQI of P applied at output. 
QWDATA Section 3.4 Option 4 – Data Output

Water Quality 101 NWIS User

NOTE: If results have DQI codes that indicate they are proprietary (P, O, X) or that they are 

awaiting review or from unapproved methods (I or U), the results may not be available for 

retrieval by all users. Only users with certain access will be able to retrieve results with 

these DQI codes.

qwtable -- select result inclusion by DQI

The following categories are available:

A – Historical

S -- Presumed satisfactory

R -- Reviewed and accepted

Q -- Reviewed and rejected

I -- In review

U -- Unapproved method

P -- Proprietary, unreviewed

O -- Proprietary and approved 

X -- Proprietary and rejected 

Enter ‘all’ or letters for categories desired, no space between:

2. Parameter Order:

Allows you to specify if data will be tabled in approved USGS publication order or in the 

order specified by the user on input. 

qwtable -- select constituent ordering

Do you want numeric parameters in “publication” order (Y/N, 

<CR>=Y)?

NOTE: If alpha parameter codes are included in the list of parameters to be included in 

the output and publication ordering is selected, the parameters will not be included in 

publication order. To include alpha parameter codes with publication ordering, include 

the alpha parameter codes at the beginning of the parameter list.
QWDATA Section 3.4 Option 4 – Data Output

Water Quality 102 NWIS User

3. Rounding of Result Values:

qwtable -- select rounding

You have 3 options for rounding of parameter values--

D --Default, use default rounding

U --User, use rounding stored with parameter

N -- None, output analysis value as stored 

Enter option desired (<CR>=D):

Default rounding (D) produces tables with each parameter value rounded using the 

rounding instructions array in the parameter-method table. A discussion of the rounding 

is included in the “Programs” section, “Support Files” (Section 3.6.8) and in Tip Sheet 

5.19, “How can I round my results in QWDATA output.” The precision of results is based 

on an analysis of the variability of replicate measurements. Lacking such an analysis, you 

should select the “Default” rounding when preparing tables of water-quality data for 

publication. The “Default” rounding is based on laboratory analysis of the most precise 

method currently available and uses precision data stored in the parameter-method table. 

User-defined rounding (U) produces tables with each parameter value rounded using the 

rounding instruction stored with the analysis at the result level. If this option is selected, 

and the rounding code is not stored with a sample, the software will use the rounding 

code stored in the parameter-method table. 

No rounding (N) produces tables in which each parameter is written as entered in the 

database. Calculated results (Section 2.6.1) are written with one more significant digit 

than would be produced if the result were rounded. 

Note: Due to a nine-character field width restriction, the program is unable to display 

values with nine or more digits.

4. Censoring of Zero Values: 

Selecting to censor zero values makes available three other options. Option 1 is the 

default— zero values are not censored. Option 2 allows you to censor stored zero-value 

measurements based on a reference list (Appendix I); zero values will be converted to a 

null value and the remark code will be changed to U (Analyzed for, but not detected) for 

parameters in this list. Option 3 allows you to enter parameter codes and values 

interactively, so that each parameter code and value pair can be set individually. Option 

4 allows you to enter a file that contains individual parameter code and value pairs; the 

file must be in fixed-column format (Appendix G). 
QWDATA Section 3.4 Option 4 – Data Output

Water Quality 103 NWIS User

The reference list (Appendix I) will also be applied to censor parameters not entered 

interactively or from a file. Note: this option does not apply to fixed-value parameter 

codes, where an integer is coded in place of a text explanation. 

qwtable -- set up user censoring of stored zero values

You have 4 options: 

1 -- no censoring of zero values

2 -- censor by reference list only

3 -- specify parameter code & value for selected parameters at the terminal

4 -- load a set of parameter codes with value from a file

Enter option desired (1-4, <CR>=1):

5. Recensoring of Values:

By selecting Option 5, six options are available for censoring data at a new censoring 

level (recensoring). Recensoring does not change anything stored in the database. In 

output tables, however, any stored values less than the recensoring value are displayed as 

recensored values and qualified with a “<” (less than) remark code. Recensoring may be 

useful for focusing the data user’s attention on the higher data values and away from 

visual differences that are not relevant to understanding environmental processes. Note: 

this option does not apply to fixed-value parameter codes, where an integer is coded 

in place of a text explanation. 

qwtable -- set up user re-censoring

You have 6 options for recensoring of constituents:

1 -- No recensoring

2 -- Recensor all constituents to a specified value

3 -- Recensor each constituent to the highest associated reporting level 

stored for the constituent-method

4 -- Recensor values for specified parameters and methods

5 -- Recensor each value that is below the associated reporting level

6 -- Recensor each constituent to the highest censored level

Enter recensor option desired (1-6, <CR>=1):

Option 1 (default selection) includes results in output as they are stored in the database. 

Results in the database are censored by the laboratory at a specified reporting level. This 

reporting level varies depending on the constituent and the analytical method. In addition, 

the reporting level can change over time due to the conditions under which the sample is 

analyzed or the chemical characteristics of the sample. 
QWDATA Section 3.4 Option 4 – Data Output

Water Quality 104 NWIS User

Option 2 allows you to recensor all constituents in the data output to user-specified 

value. The output will display all results that are below the selected recensoring level as 

less than the recensored value chosen. This option would most likely be used for 

comparisons among constituents, methods, and (or) laboratories. 

In the example below, the user has chosen a recensoring level = 10. The values in bold 

have been recensored for output. 

Parameter code Stored value Output

01020 2 <10

01046 3 <10

00915 10 10

00930 15 15

00940 22 22

In the example below, the user has chosen a recensoring level = 0.1. The values in bold 

have been recensored for output.

46342 <0.05 <0.1

77825 <0.1 <0.1

QWDATA Section 3.4 Option 4 – Data Output

Water Quality 105 NWIS User

Option 3 allows you to recensor all constituents to the highest stored associated reporting 

level for each unique constituent-method combination. This option references only those 

results in the selected records. If none of the measurements for a constituent-method 

combination are associated with a stored reporting level (e.g., data stored prior to NWIS 

4_1 or transmitted by a laboratory with no reporting level), then no recensoring is 

performed on those results. 

In the example below, parameter codes 01046(G0052), 46342(GC058), 77825(GC098), 

and 46342(GC065) have stored reporting levels, and the highest for each constituentmethod combination is used to censor results in the output. The values in bold have been 

recensored for output.

Option 4 allows you to specify a new censoring level for each constituent-method 

combination. You may do this interactively by entering the parameter code, method code, 

and recensoring value at the terminal or by using an input file. The input file must use the 

fixed-column format shown in Appendix G. This technique would most likely be used for 

spatial or trend analysis without regarding effects from compound interferences or 

changes in laboratory performance. This option provides the maximum amount of control 

over recensoring. Constituents not specifically identified in the user-specified recensoring 

limits will not be recensored. 

In the example below, the user has entered the following measurement-specific 

recensoring levels: 01046(G0051) = 5; 46342(GC058) = none; 77825(GC098) = 0.2; 

46342(GC065) = 0.15. The values in bold have been recensored for output.

Option 5 allows you to censor each result that is below the associated reporting level for 

that result. The most common application of this option is to remove the results coded 

with an “E” remark code that identifies results below the reporting level. This technique 

would be used to reduce the probability of false positive detections in the data reporting. 

If no reporting level is stored with the result, then no recensoring is performed on the 

value. 

In the example below, reporting levels for 01046(G0052) and 46342(GC065) affect the 

output of result values. The values in bold have been recensored for output.

6. Qualifiers in Output:

qwtable -- select value qualifier inclusion

Do you want to include value qualifiers (Y/N, <CR>=Y)?

Value qualifiers are codes used to provide additional information about the value reported 

by the laboratory. You may select to add or remove footnotes for remark codes and value 

qualifier codes with this option. The default for this option does not include value 

qualifiers in the table; however, they may be included if you specify them here. 
QWDATA Section 3.4 Option 4 – Data Output

7. Footnotes: 

qwtable – select footnote inclusion

Do you want to create footnotes for remark codes (Y/N, <CR>=Y)? 

Do you want to create footnotes for value qualifiers (Y/N, <CR>=Y)?

The default option will include only footnotes that define any remark codes that appear in 

the table.

8. Create a Parnames File:

qwtable – select parnames file creation 

Do you want to create a parnames file (Y/N, <CR>=Y)? 

A parnames file contains a listing of the parameter codes and names included in the 

output for the current retrieval. The name of the file will be the output file 

name.parnames. This file can be used as input for parameter names for another retrieval. 

9. Time Datum:

qwtable -- select output time datum

Such as:

GMT AST EST CST MST PST AKST HST

BST ADT EDT CDT MDT PDT AKDT HDT

Enter the acronym of the time-datum desired 

(<CR>=watch time):

This option allows for times in the output file to appear in any time datum chosen. The 

default option is to display the times using the watch time (Section 2.1.9), which is 

equivalent to the time datum entered during login of the sample.

NOTE: Time datum will appear in output for a sample if the time-datum reliability code is 

“K”; otherwise it will be blank in output unless the alpha parameter for time datum is 

specifically requested in the list of parameters.

Water Quality 110 NWIS User

10. Restrict parameters:

qwtable -- select publicly accessible parms

Do you want to limit parameters to publicly accessible 

(Y/N,<CR>=Y)? 

The default option will include only parameters accessible to the public (public retrieval 

flag = “Y”). If you select “None,” the retrieval will include parameters that are not 

accessible to the public (public retrieval flag = “N”). 

11. Display text for fixed values: 

qwtable -- select fixed value display

Do you want to display text for fixed values (Y/N, <CR>=Y)?

If you select the default option, text will not be included in the table for fixed values. 

12. Calculated-value precedence:

The following options will enable you to output values from the set of calculated 

parameters (Section 3.6.7, Appendix D) that may have stored values in the database or 

would have been computed by an algorithm. Remember that including the parameter 

CALCV in the by-sample layout will also impact this option. An example would be 

requesting CALCV with Option 3 below. That specific combination would be a 

“shortcut” to output all stored values from the algorithm list, without also including all 

numeric parameters with ADDPC.

qwtable -- select precedence for calculated parameters

The following precedences are available:

1 -- stored if available, otherwise calculated

2 -- Calculated if possible, otherwise stored

3 -- Only stored, never calculated

4 -- Only calculated, never stored

3.4.4 Option 4 – Water Quality Table by Result

This option produces a table of result-level data in columnar format. Each water-quality 

parameter for a particular sample is listed on a separate row, and result-level codes are listed in 

columns across the row. Appendix C has an example of this output. 

Upon invoking this option, you will be prompted to enter the name of the file containing record 

numbers and the name of an output file to which the table will be written. After entering these 

filenames, enter the table definition. These queries are described in detail in Section 3.4.3.1 and

Section 3.4.3.2. Note: This option cannot be used to make a type 4 – Biological table.

3.4.4.1 Specifying the Result-Level Parameter Codes

Next enter alpha (sample and result-level) parameter codes, which will comprise the table 

columns. You may enter these codes interactively from the terminal or from an existing file that 

contains parameter codes in fixed-column format. All valid sample and result-level alpha codes 

(Appendix A) and the code ALPHA, which brings in nearly all alpha codes, are acceptable 

entries. If you do not enter ALPHA, you must enter the alpha code PCODE so that parameter 

codes are printed. The parameter code REMRK is not normally included in the parameter code 

list. Remark codes will be automatically embedded in the output with the VALUE column. If the 

parameter code long name PLNAM is included in the list for output, the field will be restricted to 

54 characters in the table.

Select one of the following options to identify the columns in the table 

(alpha codes are used to identify columns):

1 -- Enter alpha codes at the terminal

2 -- Enter a filename that contains a list of alpha codes

Enter option desired (1-2, or Q to quit): 1

Enter alpha parameter codes (include “PCODE” for parameter numbers): 

(1) P: PCODE

(2) P: VALUE

(3) P: DQIND

(4) P: _________

After you have entered the parameter codes, they are checked against the parameter code 

dictionary to make sure that they are valid codes. During interactive input, parameter codes are 

checked before the next entry, and invalid entries must be reentered.

When processing is complete, the output filename is displayed, and you may repeat the steps 

described above for developing a “Water-Quality Table by Result.” (Section 3.4.4) table or 

return to the Option 4 -- Data Output (Section 3.4) menu. 

3.4.5 Option 5 – Flat File by Sample

If you select this option, you can output data to an ASCII file (flat file) that may be used to enter 

data to another application, such as a statistics or graphics application. This option is similar to 

the Water-Quality Tables by Sample (Publication Format) option (see Section 3.4.3), except 

that output is in ASCII file format rather than in table format. Examples of this type of output are 

in Appendix C.

3.4.5.1 Selecting the Output Format

Six format options are available for selecting the output format: fixed-column flat files with and 

without method codes, tab-delimited RDB files with and without method codes, or flat files with 

user-specified delimiters with and without method codes. 

qwtable -- Flat file (by sample)

You have 6 options for flatfile output:

1 -- Fixed column flat file (qwflatout)

2 -- Flat file with TAB delimiter (RDB format)

3 -- Flat file with user-specified delimiter

(Following options include method code in output)

4 -- Fixed column flat file (qwflatoutm)

5 -- Flat file with TAB delimiter (RDB format)

6 -- Flat file with user-specified delimiter

Enter option desired (1-6, <CR>=1):

If you select a fixed-column format (Option 1 or 4), data are output to equally spaced columns 

(Appendix C). If you choose a fixed-column format with method code included (Option 4), the 

method code is included adjacent to the remark code. For example, “<GC058 10.” indicates a 

less-than 10 value using method “GC058.” If you select delimited files (Options 2, 3, 5, or 6), 

you will be asked if the value and associated remark codes should be delimited. (Note: If you 

select “No,” the remark code will appear as the first column in the value field (for example 

<0.05). For most applications, this will cause the value to be read as a character rather than 

as a number.) If you select user-specified delimiter (Option 3 or 6), you will be prompted to 

enter the character that will be used to delimit the data. If no delimiter is entered, the default 

delimiter is a space. 
QWDATA Section 3.4 Option 4 – Data Output

qwtable --Flat file (by sample)

You have 6 options for flatfile output:

1 -- Fixed column flat file (qwflatout)

2 -- Flat file with TAB delimiter (RDB format)

3 -- Flat file with user-specified delimiter

(Following options include method code in output)

4 -- Fixed column flat file (qwflatoutm)

5 -- Flat file with TAB delimiter (RDB format)

6 -- Flat file with user-specified delimiter

Enter option desired (1-6, <CR>=1): 6

Enter column separator char or TAB for tab char:

Do you want remarks and values to be delimited (Y/N, <CR>=Y)? Y

3.4.5.2 Specifying the Retrieval Criteria

After you have selected the desired output format, you will be prompted for the pathname of the 

file containing the record numbers, a filename for the output file, and for parameter codes. 

Parameter codes may be entered interactively or from a fixed-column file. These queries are 

described in detail in Section 3.4.3.1 through Section 3.4.3.3.

those for tabling data by sample and are described in detail in Section 3.4.3.4. 

3.4.5.4 Output Processing

When specifications are complete, processing begins. The screen displays the parameter codes 

being retrieved, the number of parameter codes loaded, the database number being accessed, and 

the number of records retrieved. When processing has been completed, the output filename is 

displayed, and you may repeat the steps described above for developing a Flat File by Sample or 

return to the Option 4 – Data Output menu. 

3.4.6 Option 6 – Flat File by Result

If you select this option, you will be able to output data to an ASCII file (flat file) in a columnar 

format that uses one row (line) for each parameter. This format may be used to enter data to 

another application. This option is similar to Option 4 – “Water Quality Table by Result” (see 

Section 3.4.4), except that output is in ASCII format rather than in table format. The flat-file-byresult format is intended to be used as input into other computer programs; therefore, remark 

codes are not embedded within the VALUE column, as is done for the publication in a by-result 

layout. Therefore, you should normally request both columns, REMRK and VALUE, when 

preparing a flat file by result.

3.4.6.1 Selecting the Output Format

Three formats are available for output to an ASCII file. Output may be written in fixed-column 

format, tab-delimited format, or with a user-specified delimiter. 

qwtable -- Flat file (by result)

You have 3 options for flatfile output:

1 -- Fixed column flat file

2 -- Flat file with TAB delimiter (RDB format)

3 -- Flat file with user-specified delimiter

Enter option desired (1-3, <CR>=1):

If you select a fixed-column format, data are output to equally spaced columns (Appendix C). If 

you select a user-specified delimiter (Option 3), you will be prompted to enter the character that 

will be used to delimit the data. If you do not enter a delimiter is entered, the default delimiter is 

a space. 

3.4.6.2 Specifying the Retrieval Criteria 

After you have selected the desired output format you will be prompted for the pathname of the 

file containing the record numbers and for a filename of the output file. These queries are 

described in detail in Section 3.4.3.1. Next you will be queried for alpha (result-level) parameter 

codes. Parameter codes may be entered interactively or from a file. These queries are described

3.4.7 Option 7 – Flat File with TAB delimiter (Publication Export)

This option allows you to output data to an ASCII file with the TAB-character delimiting fields, 

which may then be used to prepare tables of water-quality data by using publication software. 

This option has similar features as the publication by sample (Section 3.4.3) and flat-file-bysample (Section 3.4.5) options, but it allows further customization of column headings, page 

columns, and rows. The intended usage of this output format is to help meet the prepublication 

formatting needs.

3.4.7.1 Selecting the Output Format

Because this type of table output is specific, the user has already chosen the formatting when 

choosing this option from the Data Output menu. This output format features RDB-style tabdelimited output. Within the results, for example, the remark code is always included with the 

value and is separated from the value by one space (e.g. < 0.05) (Appendix C). 

3.4.7.2 Specifying the Retrieval Criteria

Users will be prompted to identify samples. You may enter record numbers interactively or from 

a file. If the records are to be identified by record number, the format of the file is one record 

number per line, with the eight-digit record number beginning in column 1 of each line as shown 

in Appendix G. If samples are to be pulled from multiple databases, such as the QC database, 10-

digit record numbers can be used, where the 2-digit database number is appended to the 8-digit 

record number in the record number file. If record numbers are not used, the samples may be 

identified by logical keys (Appendix G, Section 2.1.1).

7. Create Parameter File:

A parameter file contains a listing of the parameter codes and parameter long names included in 

the output for the current retrieval. This file can be used as a parameter input file, but not for the 

parameter column headings. 

8. Time Datum:

11. Calculated-value precedence:

Described in Section 3.4.3.4. 

12. Include Parameter Codes:

If selected, a row will be inserted into the output file that includes the parameter code enclosed in 

parenthesis after the parameter name (for example “(00010)”).

13. Delete Column if No Data:
QWDATA Section 3.4 Option 4 – Data Output

Water Quality 124 NWIS User

If none of the selected samples contain a result for one of the requested parameters, the column

associated with that parameter will be removed entirely if you select “Yes.” If you select “No,” 

the column heading will be retained and the no-value indicator of “—“ will be printed for each 

analysis.

14. Column headings:

For numeric parameters, the default selection will be the parameter long name. For alphabetic 

parameters, the parameter short name will be used; however, if you wish to customize any 

column headings, you must format an input file with parameter code and customized text, along 

with any defined terms or symbols for a table headnote. The format of the custom input file is a 

tab-delimited, three-column file that includes: 

• parameter code (length = 5), 

• parameter column heading text (maximum length = 170), and 

• headnote definition (maximum length = 150). 

If you include a numeric or an alphabetic parameter code in the retrieval, but the code does not 

have a defined name in the custom name file, then the default parameter name will be used in the 

column heading. Also see Appendix G.

15. Date Format:

There are four options for displaying the sample dates, as shown in the menu. Three of the 

options list the month (MM), day (DD), and year (YYYY) in a numeric format, and one option 

spells out the month. For example, here are the four variations of the same date: 

02 28 2010, or 

02-28-2010, or 

02/28/2010, or 

February 28, 2010. 

16. Title:

You may enter a title for the publication export file that will appear on a single row in the file. 

The title text may be up to 500 characters in length.

3.4.8 Option 8 – Make a P-STAT Data Set

When you choose this option, selected data from specified records may be written to a sequential 

file that may be read by the standard P-STAT input routines. When you choose this option, you 

should select “no rounding.” If you do not select “no rounding,” the data output file will 

contain blanks and the P-STAT software will not be able to read the file. Examples of this type 

of output are available in Appendix C. 

3.4.8.1 Specifying the Retrieval and Output Criteria
QWDATA Section 3.4 Option 4 – Data Output

Water Quality 125 NWIS User

You will first be queried for the pathname of a file containing record numbers and the pathname 

of an output file. These queries are the same as those for the other options in “Data Output” and 

are described in detail in Section 3.4.3.1. 

After you have specified these files, you will be prompted to enter an output format option. 

Three options are available for handling values that include remark codes. 

qwtable -- P-stat format

p-stat output format

You have 3 options for handling remarks codes

1 -- Remarks (<, ND, etc.) included with the data

2 -- Remarks deleted but values retained (a remark code

of “ND” or “M” will yield a value of “-“, a missing value 

of the first kind

3 -- Values with remarks codes set to “--“, a missing value 

of the second kind

A count of the remarked values will be provided

Enter your choice ( 1-3):

1. Option 1 - Remark codes may be included with the associated values in the output file. 

Note: This format is invalid for input to P-STAT because P-STAT cannot handle 

remarks in this manner; it is provided for data verification only. 

2. Option 2 - Remark codes may be suppressed and only the associated values are included 

in the output file. For a remark code of ”ND” (not detected) there is no associated value; 

the output file will contain “--” (defined in P-STAT as a missing value of the first kind). 

3. Option 3 - All values associated with remark codes may be replaced with “--” (defined in 

P-STAT as a missing value of the second kind). 

Regardless of which option you choose, a summary list of remarked values is produced in a 

separate output file.

Next, you will be queried for a list of parameter codes either entered interactively or from a file 

that contains a list of parameters (Appendix G). If the parameter list is not in a file, enter each 

parameter from the terminal; enter a null entry (<CR>) to end the list. Only numeric parameters 

and the three alpha parameters (Appendix A) ADDPC, CALCV, and SAMPL are valid. A 

maximum of 1,000 parameters may be included. These queries are described in detail in Section 

3.4.3.3.

Do you wish to run again (Y/N, <CR>=N)?

Three output files are created. The first file contains data retrieved for each record number 

requested and is given the user-specified name. Each record has at least two 80-character lines. 

The first line for each record contains the station number, begin date, begin time, end date, and 

end time. If date or times are missing, as they may be for some historic samples, they are 

represented by “-” (defined by P-STAT as a missing value of the first kind). Each remaining line 

for each analysis contains a maximum of eight data values. Each value occupies nine spaces and 

is preceded by a blank. If there is no value for a requested parameter, the value is represented by 

“-” (defined by P-STAT as a missing value of the first kind). See Section 2.7.1 for information on 

rounding. 

A second output file is named by adding “.CMND” to the user-supplied filename. This file 

contains the P-STAT commands that are needed to identify the variables and the commands to 

read the data into P-STAT.

The third output file is named by adding “.STATS” to the user-supplied filename, and it contains 

a summary of all values that have remark codes. The list includes (for each parameter code)

every unique combination of remark code and value found, and a count of occurrences of that 

combination. 

When processing is complete, the name of the file containing the data is displayed, and you may 

repeat the steps described above for developing a P-STAT file (see Section 3.4.8), or return to

When in the QWAPPLICATIONS menu, you can use UNIX commands such as “ls” or “more” 

to list a directory or examine the contents of a file. When the selected program has completed, 

you will be returned to the QWAPPLICATIONS menu shown above. Use Option 99--Exit 

System to exit the software and Option 98--Exit Menu to return to the previous menu. 

Options 1 and 5, qwplot and qwregress, require that a UNIX environment variable called 

DISPLAY be set to allow the program to plot in a separate window on your screen. The variable 

must be set from outside of QWAPPLICATIONS. The first message after invoking either of 

these programs is a message asking you to confirm that the variable DISPLAY has been set 

correctly.

The use of Ctrl-C to break out of any of these programs should be used with caution. Various 

results can occur if “no” is the response, including a hung cursor or using the “no” response for

another question in the queries. It is best to break out using the “yes” response to the quit and 

start over in the program of your choice. 

Input and Output Files for QWAPPLICATIONS 

All programs in the QWAPPLICATIONS menu require an input file—either record numbers or 

data—to operate and an output file. Options 1–5 require an input file containing record numbers 

from the QW database, and this file has the format of one record number per line in columns 1–8 

and can be generated through QWDATA (see Section 3.3.1) or created by using an editor. 

Examples of this input file are shown in Appendix G. 

Applications Output 

Options 1–5 generate graphics that require you to specify the output format. Options 1 and 5 use 

TKG2 to produce the plots, and the other options use S-PLUS.

From the TKG2 window, you can print the plot, save it as a TKG2 or G2 file, or export it into a 

FrameMaker Interchange Format (*mif), Portable Document Format (.pdf), Portable Network 

Graphics (.png), or a Postscript file (.ps). 

If you save plot as a FrameMaker Interchange Format (*mif), you will need to complete some 

editing of the graph, so that the entire plot can be seen on the page. To do this, open the *mif file 

in FrameMaker; use “Select All on Page” from the Edit pulldown menu; then choose “Group” 

from the Graphics pulldown menu; finally choose “Scale” from the Graphics menu, and make 

the scale factor 80 percent. You can move the entire plot to center it on the page after it has been 

scaled down in size. 

When you save a plot in TKG2 format, you can edit it using TKG2. Open the plot in TKG2, and 

double click on the axis you would like to edit, or double click on the explanation to edit the data 

points in the plot. Use the editing windows that are displayed to change the appearance. To 

continue with the plotting program, exit from the TKG2 window. 

When you use the programs that invoke S-Plus, a directory named NWIS_Swork is created in 

your home directory. This directory will contain any files that are made while using the S-Plus 

graphics programs. When the graphics that invoke S-Plus are selected, the following list of 

device types is displayed.

If you select Option 1, a separate S-Plus window appears that includes the plot. To exit cleanly 

from this window, you should include all responses in the UNIX window, not in the S-Plus 

window. If you select Option 2, a PDF file is generated after you enter a filename. Known bugs 

exist for diagrams generated in a PDF format from the S-Plus window. For boxplots (Option 2 

from the main QWAPPLICATIONS menu), the y-axis label is missing. If you select Option 4, a 

plot file in HP Laser Jet format is produced that you can print on printers that accept HP 

formatted graphics. If you select Option 5, a Postscript file is produced that you can print on 

printers that accept Postscript format. If you select Option 7, the plot will appear on a Tektronix 

4010 window. To use a Tektronix 4010 window, you must be using an xterm window. When you 

select Option 7, a message appears in the UNIX window: “Enable Tek window output now.” 

While you are still in the UNIX window, press CTRL and the middle mouse button at the same 

time, and then activate the Tektronix window by selecting “Switch to Tek mode.” To view each 

plot, hit “enter” in the Tektronix window after each plot. To return to the UNIX window, desect 

“Switch to Tek mode,” press CTRL and the middle mouse button at the same time, and deselect 

“Show Tek mode. If you select Option 9, you can choose the size of the plot you want and then

NOTE: EPS files must contain only a single plot. This option will create multiple files. The filename 

format is basename_##.eps. 

3.5.1 Option 1 – X,Y Plot

The qwplot program (Option 1) creates an X,Y plot in three stages: (1) by retrieving data from 

the QW database that are written to an ASCII file, (2) by using data in the ASCII file to create 

the plot in a separate graphics (TKG2) window, and (3) from the TKG2 window, the plot can be 

printed or saved to a file. All data are used in the plot, including remarked (i.e., less or greater 

than) results. Plots created with QWPLOT are limited to 5,000 data points. 

The three stages used to complete the plot are described, and the software requests the name 

of the file containing the record numbers. The next prompt asks for the name of the output 

filename. 

Three options exist for plotting the data: (1) from one to seven parameters by one parameter, (2)

from one to seven parameters by sample date, and (3) from one to seven multiple stations by 

sample date for one parameter. All three options will handle data from multiple stations; 

however, only Option 3 will identify the individual stations on the plot. 

If you choose Option 1, you must enter a five-digit parameter code for the x-axis followed by as 

many as seven parameters that will be plotted on the y-axis. If you choose Option 2, the x-axis 

parameter is sample data, and you can enter as many as seven parameters to be plotted on the yaxis. If you choose Option 3, the program reminds you that the file containing the record 

numbers must be sorted by station ID, date, and time. The x-axis parameter is sample data, and 

one y-axis parameter can be entered.

After you choose the plot type, the data are retrieved, some basic statistics (e.g., n, minimum, 

and maximum) are displayed on the screen, and you are asked if the data are to be listed to the 

screen. These data are the same data included in the ASCII output file and in the plot. You can 

then enter a title for the plot, and you can edit the x-axis and y-axis labels if the default choices 

are not acceptable. Although there is no limit on the length of the plot title or axis labels that can 

be entered, there is a practical limit because all text entered may not be visible on the plot. You 

may need to edit the font size in another application to see the entire title or label. You then can 
QWDATA: Section 3.5 Option 5 – Applications 

Water Quality 133 NWIS User

choose whether the plot points will be connected with lines. Several seconds after this response, 

a separate TKG2 window will appear that contains the plot you requested. 

3.5.2 Option 2 – Boxplots

The qwboxplot program (Option 2) creates boxplots in two stages: (1) by retrieving data from 

the QW database that are written to an ASCII file and (2) by using data in the ASCII file to 

create the plot in a separate graphics (S-Plus) window and write the output to a file. A boxplot is 

a simple graphic means of displaying statistics for the distribution of reported concentrations for 

a constituent. This program can generate several types of boxplots. The ends of the box (hinges) 

define the range of the middle 50 

percent of the data, which is that part of the data between the 25th and 75th percentiles (the 

interquartile range). The median value of the data, the 50th percentile, is defined by a line across 

the box. The lines beyond each end of the box are called “whiskers,” and, in a schematic boxplot, 

they extend to the last value within 1.5 times the interquartile range beyond the ends of the box. 

Data points beyond the whiskers are called “outliers,” because their values differ greatly from 

the rest of the data. Outliers that extend from 1.5 to 3 times the range of the 25th and 75th 

percentiles are plotted as an “x,” and outliers that extend more than 3 times are plotted as an 

“o.” In a truncated boxplot, the whiskers extend to the 10th and 90th percentiles. 

The qwboxplot program requires the standard input file of record numbers and an output file. 

The output file documents the retrieved data and is used as input to the plotting routine. The 

program then asks if you want to make a boxplot by using one station with one or more 

parameters, multiple stations with one parameter, or multiple stations treated as one station.

For any of the three options, the next request is for parameter codes that will be included in the 

boxplot. If you select Option 1 or 3, you can enter as many as 15 different parameter codes. The 

data values for each parameter code will be used to complete a boxplot for that parameter. If you 

select Option 1 and if the record number file includes data for more than one station, only the 

first station listed in the record number file will be used. If you select Option 2, one parameter 

code is entered, and the data values for each station will be used to complete a boxplot. If more 

than 15 stations are included in the record number file for Option 2, 16 stations will be shown on 

the x-axis, but only 15 boxplots will be drawn. Boxplots drawn for groups with less than 10 data 

values may not be complete. For example, if only one data value is available, only the median 

line is displayed. If plots for less than 10 data values are used for other than exploratory data 

analysis, groups with less than five data values should be displayed using the individual points. 

The data are retrieved, and summary statistics are displayed on the screen like those displayed 

below.

The next queries ask whether you want the data to be listed to the screen and whether you want 

to plot the data. If you want to plot the data, then the options for the types of boxplots are 

displayed (schematic or truncated). After you select the type of boxplot, you can supply the title 

of the plot, the y-axis label (if you want it changed), and the x-axis label (if you want it changed). 

The S-Plus list of devices is displayed and you must select an output option as described above. 

The data for the most recent boxplot are saved in the NWIS_Swork directory as an S-plus dataset 

called spgu.boxplt. These data can be used in any S-Plus analysis. There is a USGS library for Splus that facilitates hydrologic analyses.

3.5.3 Option 3 – Stiff Diagrams

The qwstiff program (Option 3) creates Stiff diagrams (Stiff, 1951) in two stages: (1) by 

retrieving data from the QW database that are written to an ASCII file and (2) by using data in 

the ASCII file to create the plot in a separate graphics (S-Plus) window and write the output to a 

file. By using S-Plus, Stiff diagrams are plotted in a separate window by using an input file of 

record numbers. 

The Stiff diagram is a graphical representation of the cations and anions of an analysis in 

milliequivalents per liter. The Stiff plotting technique uses parallel horizontal axes extending on 

each side of a vertical zero axis (Hem, 1985, p. 175). Concentrations of the cations are plotted to 

the left of the vertical axis and anions to the right. The points are then connected, and an irregular 

pattern results. Thus, the patterns can be compared among analyses as well as among sites to 

illustrate similarities and differences. 

The NWIS software plots the cations calcium and magnesium alone, and it combines the cations 

sodium and potassium. The anions, bicarbonate and carbonate, are combined, chloride and 

fluoride are combined, and sulfate is plotted alone. Each plot represents one analysis. All data are 

used in the plot including remarked (i.e., less or greater than) results. The software will not plot a 

Stiff diagram if any of the parameters are missing. Below is an example of a Stiff diagram 

produced from the software. 
QWDATA: Section 3.5 Option 5 – Applications 

Water Quality 137 NWIS User

When the program is invoked, a query appears and asks if you want to plot the station name 

(local well number) instead of the station number. The program then requests the input filename 

of record numbers and the output filename (the output file is referred to as the “Sample Printout 

File”). The S-Plus list of devices is displayed, and you must select an output option as described 

above. 

The output file (ASCII) contains the station number, date, and time for each record and a list of 

cations and anions. A missing value is represented by “-1.” An asterisk (*) indicates that the 

bicarbonate value was computed from alkalinity, and a message is included at the end of the 

cation and anion list. 

3.5.4 Option 4 – Piper Diagrams

The qwpiper program (Option 4) creates Piper diagrams (Piper, 1983). Piper diagrams can be 

used to show the chemical character of water. In a Piper diagram, selected cations (positively 

charged ions—calcium, magnesium, and sodium plus potassium) and anions (negatively charged 

ions—bicarbonate plus carbonate, sulfate, and chloride) for each analysis are shown as a 

percentage of the total cations and anions, in milliequivalents per liter. The cations are plotted as 

single points in the triangle on the left side and anions in the triangle on the right side. Cation and 

anion plots for each sample then are projected into the central diamond field. A water type can be 

described depending on the location of the projected point in the central diamond. The Piper 

diagram can be used to determine whether a particular water is (1) chemically similar to some 

other water or (2) a simple mixture of two chemically different water types (Hem, 1985, p. 177–

179). 

A water type in which one cation and one anion dominate (each amounts to 50 percent or more 

of the cations or anions, respectively) is designated by the names of the dominant cation and 

anion. A water type in which no cation or anion dominates is designated a mixed-cation or 

mixed-anion type (Piper and others, 1953, p. 26). 

When the qwpiper program is invoked, the program asks for the file containing the record 

numbers (same format as Option 1), and then for the output filename. This output file is the 

ASCII file created for use with the plotting routine. If the filename exists in the working 

directory, the program asks if you want to overwrite the current file. Up to 2,000 points can be 

plotted using qwpiper. The program then displays the following options.

If you select Option 1 or 3, you are prompted for a symbol (marker) number from 0 to 18 that 

corresponds to symbols listed in table 10. If you enter a carriage return, the default is 0, a square 

symbol. If you select Option 4, the program displays the following two options that allow you to 

choose when the symbols change. 

CHANGE SYMBOLS ON:

*******************************************

 1. EACH SITE (STATION)

 2. EACH SAMPLE, REGARDLESS OF SITE

 (COLOR CHANGES ON EACH SITE ONLY)

*******************************************

0 Square 10 Circle with + inside 

1 Circle 11 Four small triangles joined 

2 Triangle 12 Square with + inside 

3 Plus symbol 13 Circle with X inside 

4 X symbol 14 Square with a triangle inside

7 Square with X inside 17 Filled-in triangle 

8 Asterisk 18 Filled-in diamond 

9 Diamond with + inside

Table 10. Symbols used for data values in Piper diagrams

When you select symbol Options 2 or 4, symbols can be changed for each site or each sample. A 

choice of two symbol sets is available with Options 2 and 4. One set of symbols is the S-Plus 

symbol set, shown in table 10; the second set of symbols contains small and capitalized letters of 

the alphabet (52 different symbols). When you choose symbol Options 3 or 4, different colors 

are used to show a change of station (or, possibly, samples when Option 4 is used). The colors in 

the order they will be displayed are black, red, green, blue, yellow, cyan, and magenta. For 

Option 3, you choose a symbol, and a different color is used for each station in the plot. If more 

than 7 stations are plotted, the colors start over, so that the first and eighth stations will be black. 

The following table shows the colors that will be shown given the number of stations plotted (the 

station order is the same as in the record number file).

For Option 4, the colors are used in the same order and the symbols are used in the order shown 

in Table 10. The colors and symbols are repeated when all have been used. The following 

example shows the colors and symbols that would be plotted if Option 1 –“CHANGE

8 Black/Square with X inside

9 Red/Asterisk

10 Green/Diamond with + inside

The final option is the size of the symbol to be plotted. 

After you have entered the options for the plot, the S-Plus list of devices is displayed, and you 

must choose an output option as described above. 

After you enter an output option are entered, an output file and plot are produced. The output file 

contains a list of cations and anions, the station number, date, and time for each record. A 

missing value is represented by “-1.” An asterisk (*) signifies that the bicarbonate value was 

computed from alkalinity. 

The data for the most recent plot are saved in the NWIS_Swork directory as an S-Plus dataset 

called spgu.piper. These data can be used in any S-Plus analysis.

The figure below is an example of a Piper diagram produced from this program. 

3.5.5 Option 5 – Regression Plots

The qwregress program (Option 6) creates an X,Y plot that can include a line calculated from a 

linear regression computation to fit a line through a set of results. The linear regression is 

performed by the IMSL subroutine RLONE and is described in the “IMSL Reference Manual,” 

v.4 (IMSL, Inc., 1982). The confidence interval for the coefficient and for the intercept is 95 

percent. In the output file, the results of the regression computation are included with the data 

used in the computation. 

The regression plot and output file are created in three stages: (1) by retrieving data from the QW 

database that are written to an ASCII file and the linear regression is computed, (2) by using data 

in the ASCII file to create the plot in a separate graphics (TKG2) window, and (3) from the 

TKG2 window, the plot can be printed or saved to a file. All data are used in the plot, including 

remarked (i.e., less or greater than) results. Plots created with qwregress are limited to 9,999 data 

points. You must have at least three values for the program to work. After describing the three 

stages used to complete the plot, the software requests the name of the input file of record 

numbers. The next prompt asks for the name of the output data file, which is an ASCII file that 

contains the data and results from the regression computation. 

You must enter a code that describes whether one plot should be made for all stations or if one 

plot should be made for each station in the record number file. After you enter the code, you 

have the option to include the regression line on the plot. Enter one parameter code for the x-axis 

and one for the y-axis. After entering each parameter code, you can enter a multiplier that will be 

used on the values for that parameter. The next prompt asks whether log transformations should 

be performed on the values for the x and y axes. A summary of the variables to be used in the 
QWDATA: Section 3.5 Option 5 – Applications 

Water Quality 142 NWIS User

regression computation and plot is shown on the screen. You can use this summary to determine 

if the choices are correct. If the choices are not correct, you can reenter the information. 

Several seconds after answering “Yes” to whether or not the regression variables are correct, a 

separate TKG2 window appears that contains the plot you requested. To continue with the 

plotting program, exit the TKG2 window. After the TKG2 window is closed, you are asked if 

you would like another set of parameters processed. If “Yes,” the program asks for the x-axis 

parameter code and follows the steps described above; if “No,” the program ends. 

3.5.6 Option 6 – Summary Statistics Table

This option runs a program that reads data and parameter-name files created by using Option 5 

(flat file by sample) from the Data Output menu. To create these files, select a fixed-column flat 

file from the output format selection (see Section 3.4.5.1, Selecting the Output Format). These 

output files are used to produce a table of summary statistics. The heading on the summary table 

requires information from the SITEFILE that is obtained by using the following alpha codes as 

the first three codes in the parameter list used to make a flat file by sample. 

AGNCY, STAID, DATES

The above three codes must be present in the parameter list. The following code also may be 

present. 

81024 (DRAINAGE AREA) may be included and will be used as the drainage area in 

place of the contributing drainage area. 

The program asks for the name of the fixed column, space-delimited file. The program then asks 

for the parameter-list filename. This file is created by a run of qwflatout, or you may create your 

own file by using the format described in Section 3.4.5.1. The names need to be in the same 

order as the input data. The program then prompts for the output filename and asks if you wish to 

report estimated percentiles for censored parameters. 

At this point, the interactive portion of the qwprcntl program is finished. This program may run 

for a long time, depending on the number of parameters that are to be processed and the number 

of records. 

Parameters in the output from the program are listed in publication order. The order in the input 

files is ignored. A log-probability regression procedure is used to estimate the mean (and the 

percentiles, if requested) of censored parameters. This procedure handles multiple-detection 

limits. The methods used are as listed below. 
QWDATA: Section 3.5 Option 5 – Applications 

Water Quality 143 NWIS User

Uncensored parameters: 

1. The data are ranked in ascending order, and positions for the percentiles are found using 

the following formula: 

K = Pct * (N + 1)/100 , 

where K is the expected position, Pct is the integer percentile (e.g., for the 5th percentile, 

Pct = 5; for the 25th percentile, Pct = 25) and N is the number of observations. 

If the position K is a whole number, then the value in that position in the rank-ordered 

data is the value used for the percentile. If K is not a whole number, then the following 

interpolation is used: 

P(Pct) = X(trunc(K)) + (K-trunc(K)) * (X(trunc(K)+1) - X(trunc(K))) 

where P(Pct) is the desired percentile, X() is the rank order data set, trunc(K) is the 

truncated value of K, and Pct is as above. 

2. If the number of observations is greater than 1 and less than or equal to 5, only the 

maximum and minimum are reported. 

3. If the number of observations is equal to 1, only the maximum is reported. 

4. If the maximum is equal to 0.0, only the maximum is reported, regardless of the number 

of observations. 

5. All values in uncensored parameters are treated the same regardless of any codes 

associated with those values.

Censored parameters:

1. If the percentage of values flagged with “<” or “U” is greater than 5 percent of the total 

number of data values for the parameter, the parameter is considered censored. 

2. The mean of censored parameters is estimated with a log-probability regression 

procedure. The method estimates the values below a detection limit and uses these values 

and the detected values of a parameter to estimate the mean. The FORTRAN 

implementation of this method was done by the former Systems Analysis Group, WRD, 

and USGS. This method was chosen as the best way to handle the problems presented by 

multiple-detection limits in water-quality data. The estimated mean is flagged with an “*” 

and explained in a footnote on the statistical summary table. If the number of censored 

parameters included in the computation is 95 percent or more of the total number of 

values to be used, the mean will be reported as “**********” in the output table. 

3. If estimated percentiles are requested, the same procedure that is used to estimate data 

below the detection limit for the calculation of the mean is used to estimate the data 

below the detection limit and to calculate the percentiles. The percentile values are 

calculated using the same method as described in Part 1 of the previously mentioned 
QWDATA: Section 3.5 Option 5 – Applications 

Water Quality 144 NWIS User

uncensored methods. These values also are flagged with an “*” to indicate that they are 

based on an estimated data set, and the “*” is explained in a footnote. 

4. If nonestimated percentiles are requested, only actual values are used for the percentile 

values in the statistical table. The percentiles retain a “<” flag if one is associated with the 

value originally and no interpolation between values is used. To establish the set of sorted 

data that the percentiles are selected from, all values flagged with “<” or “U” are assumed 

to be less than any value without a flag. For example, the following values are shown in 

the ascending order that would be used. 

<0.1 <1 <20 .01 17 500 

a. Only “<” and “U” remark codes are used to distinguish censored from uncensored 

parameters, and subsequently values flagged with these remark codes are established 

as less-than values in the statistical procedures. Other remark codes are processed as 

follows: 

E, A, S, V, and R — treated as a detected value; 

> — values dropped from statistical procedures if a censored value is also present in 

the sample set;

M — values dropped from statistical procedures; and 

N — values dropped from statistical procedures. 

b. If the average of two values must be taken to obtain the value for a percentile, the 

remark code of the greater value is associated with the percentile. 

c. Any values equal to 0 in a censored parameter are replaced with the value of the 

nearest less-than value (in time-order) and the remark code is set to “<.”

d. If the number of observations above the detection limit is less than 5, the estimated 

values are considered unreliable and are not reported. 

e. If the total number of observations (above and below the detection limit) is greater 

than 1 and less than or equal to 5, only the maximum and minimum are reported. 

f. If the total number of observations is equal to 1, only the maximum is reported. 

Effective limits of the program:

1. The maximum number of parameters (header and water quality) cannot exceed 1,000. 

2. The maximum number of values per parameter per station is set to 5,000. 

3.5.7 Option 7 –Detection-Limits Table

The qwdetlims program (Option 7) reads the data and parameter-name file created by a run of 

qwflatout (Section 3.4.5.1) and produces a table of detection limits. The heading on the table 

requires information from the QW database that is obtained by using DATES in the parameter 

list passed to qwflatout. 

The qwdetlims program produces a table of detection limits encountered in the input data file for 

each parameter in the parameter list file, excluding the alpha parameter codes and the numeric 

codes for mean discharge, instantaneous discharge, and drainage area (00060, 00061, and 81024, 
QWDATA: Section 3.5 Option 5 – Applications 

Water Quality 145 NWIS User

respectively). A maximum of 350 valid numeric parameter codes can be handled by the program, 

and a maximum of 19 years can be processed for each run. 

The program asks for the input data filename created by qwflatout. The program then asks for 

the parameter list filename; this file is created by qwflatout, or you may create your own file by 

using the format described in Section 3.4.5.1. The names need to be in the same order as the 

input data. 

The program then asks for the output filename and asks if you want to specify the period of 

record to be used (19 years, maximum) or to use the dates from the input data file (only the last 

19 years will be counted). If you specify the period of record, you are then asked for the 

beginning year and the ending year. 

At this point, the interactive portion of the qwdetlims program is finished. This program may run 

for a long time, depending on the number of parameters that are to be processed and the number 

of records. 

The output table is headed by the name of the parameter from the parameter-list file, the 

corresponding parameter code, and the total of the nonmissing values encountered for that 

parameter. The table consists of a column of detection limits encountered (a data value with a 

remark code of “<” or “U”), columns of counts of detection limits encountered for each selected 

year (up to a maximum of 19 years), a summary column (the total of the counts for that detection 

limit), and a final column giving the percentage of the total, nonmissing values represented by 

that detection limit. The rows are in the order of detection limits as they are encountered in the 

input data. 

The input data file is considered as a whole. By selecting appropriate record numbers to be used 

by qwflatout, qwdetlims can be used to show detection limits encountered for a single station, a 

single county, a specific project, a single year, or any period of years up to 19. If the output from 

qwflatout had 50 years of data, it could be processed by qwdetlims in three runs. 

One use of the detection limits table is for locating probable order-of-magnitude data errors. For 

example, if a parameter has a detection limit of <0.5 for a period of years and a single (or few) 

detection limit(s) of <50, the single-data value probably should be reviewed. Another use is for 

evaluating the data before or as they are used in statistical analyses. 

3.5.8 Option 8 – Discharge Report for QW Samples

This option is used to produce a file that contains suggested water-discharge results for surfacewater-quality samples. The program will select the samples from input of record numbers or 

agency code, station ID, date, time, and medium code to generate the output file. You may enter 

this information from the terminal or from an existing file. The format of this file is described in 

Appendix G. The format of the optional input files is described in Appendix G. If you choose to 

enter the record numbers interactively, use the process used described in Section 3.3.4. Records 

can be retrieved from multiple databases during a single retrieval, if the database (“db”) numbers 

are appended to the record numbers as in the format ########db. 
QWDATA: Section 3.5 Option 5 – Applications 

Water Quality 146 NWIS User

After the desired samples are specified, you will be prompted to enter a filename for the output 

report (or “q” to quit). Next, the format of the output report is specified. As shown below, there 

are two choices.

Which format do you desire: 

1. RDB (tab-separated)

3.6.2 Option 2 – Scan for and Display Parameter Codes and Definitions

Option 2, Scan for and display parameter codes & definitions, retrieves records from the 

parameter code dictionary and displays the parameter code and descriptive name on the screen. 

Parameter codes (see Section 2.1.3) are five-digit numbers used to identify water-quality 

constituents and properties. Two types of retrievals are available: by parameter name or by 

parameter code. See Tip Sheet 5.8 for a more detailed discussion. 

NOTE: This program displays parameters that are currently valid for data entry and public display. 

Parameters that do not fit into these categories will not be displayed but can be retrieved using 

Option 3, described below.

After starting the qwpcdpeek routine, you must decide if the records will be retrieved by 

parameter name or parameter code from the following menu.

by a carriage return or a space. It does not read anything after the space to the right. It will also 

accept a range of parameters separated by a hyphen or use of the “=,” “<,” or “>.” 

If you select Option 2, a list of parameters containing the input “name” character string is 

retrieved. The program will search all parameters for any part of the string anywhere in either the 

parameter short -name or parameter long name fields. Note that parameter short names may use 

different expressions than the “official” parameter long name uses and that differing search 

results may be obtained. Input may be from a file or from the screen. Output will be directed to

3.6.3 Option 3 – Write Parameter Report to a File

Option 3, Write parameter report to a file, allows you to search or dump table-selected column 

subsets of, or the entire, parameter code dictionary to a file, based on interactively-entered search 

criteria. The basic steps are: (1) select parameters, (2) optionally sort the rows, (3) select an 

output format, and (4) select the output columns. This program routine is qwpcdtable. Example 

output is included in Appendix C. 

The parameter code dictionary contains a mix of codes used by the USGS and historical 

parameters used by the EPA. This latter group of parameter codes disallows new data entry. 

These codes are easily distinguished by parameter names and column headings appearing in all 

upper-case letters.

If you would like to retrieve the Parameter Code Dictionary with method-information and/or 

precision-arrays, see 3.6.8 Option 8 below. 

3.6.3.1 Selection Criteria

When the program is initiated, you will be prompted for an output filename. A box will next 

appear to help limit the retrieval selection criteria. The retrieval choices are shown in 11 fields, 

which reference similar columns in the parameter code dictionary.

do not select any of the 11 criteria, and you will be directed to the sorting options menu 

described in Section 3.6.3.2 below. 

When text strings are entered to restrict the search for parameters by: Long Name, Adaps Name, 

EPA-SRS Name, units, CASRN, or fraction the text strings are used as a case-insenstive text 

fragment to match the target. For example, entering "arsenic" for the EPA-SRS name will match 

both "Arsensic" and "Arsenic acid".

10) Time-series flag will only search parameters that have the flag set in the parameter code 

dictionary (parm_ts_fg) for use in time-series (ADAPS). If you enter a blank or an “N” is entered 

into this field, then this flag is not considered during the selection. If you enter a “Y” into this 

field, then this flag is considered during the selection. 

11) Public flag will only search parameters when this entry is set to “Y” or “N.” An entry in this 

field is required if the public parameter status (parm_public_fg) is to be considered during 

selection. If you enter an “N” into this field, then parameters not available to the public are 

considered during the selection. If you enter a “Y” into this field, then parameters available to the 

public are considered during the selection. If you leave this field blank, then all parameters are 

considered during the selection. 

Output will include parameters that are not available for new data entry, as well as parameters 

not publicly displayed on NWISWeb. 

3.6.3.2 Sorting Options

3.6.4 Option 4 – Check Geologic Unit Code File

Option 4, Check Geologic Unit Code File, retrieves geologic unit codes and formation names 

and displays them at the terminal. The program asks for a geologic unit code and retrieves the 

associated name.

You can provide the entire geologic unit code (for example, 111ALVM) and, if that code exists, 

get back the formation name (Holocene alluvium) or a partial geologic unit code from one to 

eight characters. An entry of the partial geologic unit code (12) results in retrieval by partial key 

search of all geologic unit codes and associated formation names between 120xxxxx and 

129xxxxx. A blank geologic unit code terminates the program. The file of valid geologic unit 

codes is located at: /usr/local/nwis/support/aageol.all.states.

After you make a choice from the menu, the program requires you to enter the required 

information from the terminal. All responses from the program are output only to the screen. 

3.6.6 Option 6 -–- List State/County Data

Option 6, List State/County Data, interacts with the FIPS file and is used to retrieve a tabular list 

of State names, State abbreviations, State codes, minimum and maximum latitudes, and 

minimum and maximum longitudes. You also may retrieve county names, county codes, 

minimum and maximum latitudes, or minimum and maximum longitudes for a single State. A 

third option allows you to retrieve all states and counties with abbreviations, codes, and 

maximum and minimum latitudes and longitudes. The output can be to the terminal or to a file.

3.6.7 Option 7 – Display algorithm in reverse Polish notation (RPN)

Option 7, Display algorithm in reverse polish notation, retrieves and lists any or all of the 

algorithms used for calculating specific parameters. Reverse Polish notation is a computational 

technique that may be visually easier to digest than a simple algebraic expression of the same 

algorithm. The output format is seven columns in width, with a variable number of rows. Each 

row represents an operational sequence step in the overall calculation; therefore, the number of 

rows will vary by computational complexity of the algorithm. You may record a trace of the 

computational steps performed by each algorithm to reach, or fail to reach, a final value. 

Additional information and discussion about this capability is included in Appendix D. 

3.6.7.1 Specifying the Algorithm Output

A series of three prompts will allow you to output a report listing the desired algorithms. You are 

first prompted to choose “all” or specific “selected” algorithm equations to retrieve. The default 

option is “selected” algorithms, and it is chosen with a <CR> or the enter key.

• Opcode: Operation code for the data-retrieval or computational operation to perform. See 

Appendix D. 

• Operand: A reference to a Constant, a result stored in a Parameter Code, or another 

algorithm calculated by Parameter Code.

• Stk: The number of discrete values on the RPN stack after the operation completes.

• Comment: Text description of the operand, including chemical-logic reasons why this 

operation is performed. 

Requesting output to a file will write an ASCII file, delimited with the TAB character, and 

require input of a filename. The columns in the tab-delimited file are the same as screen output.

3.6.8 Option 8 – Display the Parameter Method Table

Option 8, Display the Parameter Method Table, allows you to list the contents of the methodrelated reference tables. The information available for output from this menu option includes: 

parameter code, parameter name (long and short names), historical method code (prior to NWIS 

4.6), method code, rounding (precision) array, method name, method description, method 

number, citation for the method, and long citation description for the method. You may select all 

parameter-method pairs in the output or specific parameters or may specify specific parameters 

and methods. Sample output can be found in Appendix C. 

Note: You may only retrieve historical parameter information (those disabled for new data-entry) 

by retrieval of “all” or specific parameters. 

For each parameter-method code pair in the parameter-method table, a rounding array is stored 

for a range of expected values. This rounding array is used when default rounding is selected for 

output (see Section 3.4 for more information on output from QWDATA). More information 

about the parameter-method table is available in Section 2.5.6. The parameter-method table 

contains one 10-element integer array (PROUND) that contains the default rounding codes for 

each parameter-method pair. The magnitude of the greatest significant figure in a result 

determines which PROUND element (1–9) is used to round the result. The tenth element of the 

array (MAXDEC) indicates the maximum number of decimal places that may be used to display 

a value for the parameter-method combination. The elements of the PROUND array have 

definitions as shown the example below for parameter code 00010/method THM01, water 

temperature, with PROUND array: 0012333331.

All four output options include a column named “newentry” that indicates if a parameter and 

method pair is disabled for new data entry. This column will be blank if the parameter-method 

pair may be used for data entry or “disabled” if forbidden. Sometimes, no data entry is allowed 

for a particular parameter, regardless of method; in this instance all method rows for the 

parameter will show the text “disabled” in the “newentry” column. 
QWDATA: Section 3.6 Option 6 – Support Files

If you select Option 1, the output will include all of the available information for the parametermethod pairs selected in a tab-delimited output file. The output includes: parameter code, 

newentry column, parameter short name, parameter long name, a five-character method code, a 

historical one-character method code, method name, method description, a short citation for the 

method, a citation description, method source and number, the method precision array, and the 

method precision array owner. This type of output can be very difficult to read on the screen, so 

you might consider directing the output to a file for review in another program, such as Excel, 

when the program queries you for an output destination. 

If you select Option 2, 3, or 4, you will receive the information listed in the menu item for your 

desired parameter-method pairs. You can direct the output to the screen or to a file that you can 

name for any of these three options. 

You can enter the requested parameter-method pairs interactively or by using an input file. The 

format of the input file is described in Appendix G. Below are the queries when the parametermethod combinations are to be displayed on the screen and are entered interactively. 

Please enter (1,2,3,4, or Q to quit): 1

Do you want the output to go to the terminal? (y,n, <CR>=y): y

Do you want to retrieve all or selected parameter-method pairs?

(enter "all" or <CR> for selected):

Do you want to enter parameter method pairs from the terminal? (y,n, <CR>=y): y

Enter parameter code-method code combinations (<CR> to quit):

Method code entry is optional. If method code is not included,

all method codes will be retrieved for that parameter. e.g.

00926

00930 PLA11

To retrieve a range of parameter codes, enter the following:

PCODE - PCODE on one line below. e.g. 00925-00935

1: 00915 _

2: 01040 – 01088

3: 00940 PLM58

When you enter selected parameters either from a file or interactively, the following tips might 

be helpful. 

1. If the method code is not included, all method codes for the valid parameter code are 

included in the output. 

2. There must be a space between the parameter and method code. If no space is included, 

an error message will appear that the input data are not in a valid format.

4. Parameters will be listed in numeric order in the output and are not determined by the 

order in the input file or the order when entered interactively. 

3.6.9 Option 9 – Display Analyzing Entity and Collecting Agency Codes

Option 9, Display Analyzing Entity and Collecting Agency Codes, allows you to list the contents 

of the Protocol Organization Table. The same codes are used for either analyzing entities or 

collecting agencies. The information available for output from this menu item include: 

Analyzing Entity and Collecting Agency code, name, and historical fixed value code (prior to

The Change Default Database Number utility allows the user to change the default number for 

water-quality databases. 

3.7.2 Option 2 – Add New Site or Modify Site Information

Option 2 is used to add a new site to the NWIS SITEFILE database or to modify the site header 

information for an existing site. When you select Option 2, you are prompted by software 

described in Chapter 5 at http://pubs.usgs.gov/of/2005/1251/.

Any information you enter is entered into the NWIS SITEFILE database. The output from this 

entry is collected in a file named “HDRsIN”’ and is available in your working directory. This 

input file is also described in Chapter 5 at http://pubs.usgs.gov/of/2005/1251/.

3.7.3 Option 3 – Station Change: Inventory, Change, or Delete

Instructions for using this program are located in Chapter 12 at 

http://pubs.usgs.gov/of/2005/1251/.

The station change program allows a user with proper access to inventory, delete, or change a 

station number. The agency code and station number are the primary keys used for identifying 

locations approved for WRD data collection. An entry in the SITEFILE is required for data 

stored in the NWIS databases. Updates that affect a station number are applied not only to the 

SITEFILE, but also to associated databases (QW, GW, ADAPS, and/or Water Use) where data 

for the site exist. If the program is used to delete a station number in the SITEFILE, the NWIS 

databases are searched, and data are located in the NWIS that are identified as having been 

collected at that site will be deleted. The delete transaction in the NWIS is an immediate delete. 

The only way to recover deleted records is by reentering them. An update to a station number is 

also performed in the SITEFILE and the associated databases. Updates should be closely 

coordinated and monitored within your Water Science Center, due to the possibility of affecting 

data in the NWIS and the national database.

3.7.8 Option 8 – Run qworphan Program 

Data relations exist in QWDATA where a record in one table may relate to one or many records 

in another table. These relations are described as being parent/child relations. When a “parent 

record” is deleted (or modified, as in the case of station change) from the database, the 

corresponding “child record(s)” should also be deleted (or modified). When the parent record is 

deleted, but the corresponding child records are not correctly deleted because of software bugs or 

improper use of SQL, “orphan records” are created. 

The qworphan program allows the NWIS Database Administrator (DBA) to remove orphaned 

records that no longer belong in the database. The program may be run from a menu, or options 

may be specified on the command line. This interface gives you the flexibility to monitor 

qworphan's activity or to run it in an automated fashion, such as a cron job. 

The qworphan program has two options. Option 1 deletes orphaned QW records that can be 

verified from a previously deleted site. Option 1 also provides a report summarizing any other 

orphaned QW records. Option 2 deletes all orphaned QW records. 

The qworphan program operates on your currently selected numbered database. 

Choosing Option 8 from the QWDATA utilities menu opens the following menu. 

QW data found. 

 qworphan

 This program removes Water Quality orphans from the database. 

 Choose from the following options:

 1 -- Delete orphan records for deleted stations. This option provides

 a report for orphan records with modified or missing site

 information. It is recommended that you run this option first.

 2 -- Delete all orphan records regardless of site information.

 Warning: there is no way to review your changes or un-do them

 with this option.

 3 -- Quit qworphan.

 Please enter 1, 2, or 3: 

3.7.8.1 Option 1 -- Delete Orphan Records for Deleted Stations 

If you select Option 1, qworphan writes a message on the screen that it is deleting orphans of 

deleted sites. Both orphaned sample records and orphaned result records are deleted for sites that 

have been deleted. 

After the orphaned records are removed, qworphan determines how many orphans of remaining 

sites it found and displays this information. The orphaned records of the remaining sites are not 

removed from the database using Option 1. The filenames of the output reports are displayed on 

the screen.
QWDATA: Section 3.7 Option 7 – Utilities 

Water Quality 172 NWIS User

Output Reports: 

Qworphan produces two reports: the first contains information related to a site’s modification 

and the second contains information pertaining to the records for a particular site. Both reports 

contain the time they were generated, the user who ran qworphan, and the database number on 

which it was executed.

The file containing the site modification history is called qworphan.stnchange.<date/time>. It 

contains the station change log information for each station change log entry associated with 

samples in qworphan. Multiple orphaned records for a site result in one entry for this site in the 

station history report. 

Like the station history program, this report shows both modern and legacy information from the 

station change log if such legacy information exists on your system. Because of the two different 

formats, some information will be missing from the older format and this is indicated by dashes.

The file containing a list of sample records is called qworphan.recno.<date/time>. This report 

contains one row for each sample that doesn't match an existing site. The report contains the 

following information: 

• record number + database number (no spaces between), 

• database number, 

• station number, 

• sample begin date/time,

• sample end date/time, and

• medium code. 

When viewing this report, please note that the date displayed here is not in the same format 

displayed by the station change log report. The times are rounded to the nearest minute and 

converted from UTC to the local time for that sample. The format of the date/time for sample 

start and end dates is four-digit year, two-digit month, two-digit date, two digit hour, and twodigit minute. For example, a sample with a date of 01-Jan-2004 14:00:00, at a place in Mountain 

Standard Time zone, shows up as “200401010700.” The sample output reports are shown in 

Appendix C. 

If errors occur when the qworphan program is run, these errors will be included in either report. 

The errors relate to something that was wrong with the database while qworphan tried to write 

data to the report. Errors that occur while writing the station history information appear in the 

qworphan.stnchange.<date/time> report. Errors that occur while writing the QW sample 

information will appear in the qworphan.recno.<date/time> report. Errors that are serious or that 

occurred before generating the report are displayed on screen or arrive in email if qworphan was 

executed as a cron job.

3.7.8.2 Option 2 -- Delete All Orphan Records 

This option removes all orphaned records from the database. After these records are deleted, the 

data cannot be recovered. It is highly recommended that you run Option 1 first and inspect the 

output reports before running Option 2. 

Unlike Option 1, Option 2 does not give you any feedback on what during the process. All 

samples that are no longer associated with a site, including those where the site was modified, 

are removed from the database. There is nothing indicating how many orphans exist or how 

many were removed.

Option 2 produces one output file that contains the processing date, the name of the user running 

the program, and the database number. No other information is shown in this report. The name of 

this file is qworphan.delete.errors.<date/time>. After writing the qworphan delete report, the 

program displays the name of the delete report and returns to the qworphan menu. As with 

Option 1, error messages may appear on screen or in email if qworphan was run as a cron job.

3.7.8.3 Running qworphan by Using the Command Line 

qworphan has a number of command line arguments that can be used to automatically cleanup 

the database. 

• --db_no <db_no> 

<db_no> is a number from 01 to 99. qworphan can work on only one numbered database 

at a time. The --db_no <db_no> option is recommended when running qworphan 

interactively.

• qworphan -1 

This option runs qworphan as if you had selected Option 1, delete orphan records for 

deleted stations. Its behavior and messages are exactly the same as those of Option 1.

• qworphan -2 

This option runs qworphan as if you had specified Option 2, delete all orphan records. Its 

messages and behavior are the same as those of Option 2. The program will not allow 

you to choose both Option 1 and Option 2 at the same time. 

• --help 

This option tells you how to run qworphan from the command line by showing you this 

list of options. 

Examples:

Execute qworphan Option 1, database 01: 

nwis qworphan --db_no 01 -1 

Execute qworphan Option 2, database 05: 

nwis qworphan --db_no 05 -2 

Execute qworphan Option 2, database 02: 

nwis qworphan -2 --db_no 02

Execute qworphan Option 1, using default database number: 

nwis qworphan -1 

If qworphan is run from a cron job, email is sent every time qworphan runs from this job. This 

email tells you that qworphan ran, how many orphans it found if the cron ran qworphan with the 

-1 option, the names of the qworphan reports, the locations of the qworphan reports, and any 

serious errors that may have occurred during the cron job. These are the messages that normally 

appear on screen when you run qworphan interactively.

Batch Processing menu. 

The options in this menu work with batch files of water-quality data. Batch files are used for 

many purposes, such as entering data from the National Water-Quality Laboratory (NWQL) and 

other laboratories, entering data from another Water Science Center or agency, entering data 

from a field computer, entering data previously rejected by the batch-loading software, and 

making large-scale revisions to water-quality data. The most common application is entering 

data from laboratories. 

Water Quality Data Transfer System

The QW Data Transfer System (QWDX) facilitates the transfer of analytical data from various 

USGS laboratories to the respective USGS customers or Water Science Centers (WSCs). A 

laboratory can upload all customers' data to a single spot (the QWDX). A WSC can obtain data 

from all its laboratories from a single spot (the QWDX), and the data will be in files formatted 

for batch entry to the QWDATA system. A database administrator should contact the QWDX 

Administrator to request access (email: GS-W QWDX Admin). 

After laboratory data are retrieved from the QWDX server, the files can be batch loaded into 

QWDATA using one of the programs described below. Automatic retrieval and processing of 

data from the QWDX server can also be set up on a user-specified schedule (cron job). Further 

details and instructions are available from within the QWDX system. 
QWDATA: Section 3.8 Option 8 – Batch Processing 

Water Quality 176 NWIS User

Batch File Format 

Pairs of tab-delimited files (typically named qwsample and qwresult) are used for sample and 

result information. The pair of batch files contains all of the fields used for database storage of 

sample-level and result-level data. The related data in the file pair are connected by a “sample 

integer” generated when the two files are created. Although the sample integer does not have any 

meaning beyond the batch-file pair, it is critical to keeping the sample and result information 

properly connected. The sample and result file formats are defined in Appendix F. 

The default behavior for the batch input programs is to look for batch files named qwsample and 

qwresult in the directory where the program is initiated. Options 2–4 of the Batch Processing 

Menu will only use the tab-delimited batch files named qwsample and qwresult in the directory 

where the program is initiated. 

Environmental and Quality-Assurance Databases

Environmental and quality-control (QC) data are entered with the batch-entry programs available 

in the menu shown above. The batch programs will load the data into the appropriate database 

based on the sample medium code and the user-selected database. The user-selected database 

will control which environmental and quality-assurance databases are used during batch 

processing. A separate internal table named env_qa controls the link between databases designed 

to contain only environmental or only QC data. This internal table should be set up for use by 

your local database administrator. If you need help with env_qa, please send email to GS-W 

Help qwdata. Multiple databases used by NWIS are discussed in Section 2.11.

Data Entry Behavior 

The behavior of the batch-input processes for the tab-delimited files (Batch Processing menu 

Options 1–4) are designed to be used for various tasks. The allowed sample transactions, 

protected result-level data, and the data types (laboratory and field) that can be updated for 

Options 1–4 are summarized in the following table.

Most of the entries allowed in the batch-file fields are self explanatory or defined in the domain 

lists for the coded fields. They are also described in Section 3.8.4 below. 

The default setting for allowed sample transactions during specific batch processes is controlled 

for each NWIS installation by the “qw.conf” file. This file is consulted only when the UNIX 

command line is used with no behavior options specified or when the user-specified behavior 

(Section 3.8.4) is used. This file is located at /usr/opt/nwis/data/auxdata/qw.conf and can only be 

updated by user nwis. You may have to contact your local NWIS DBA to update this file. A 

master version of this file is available at /usr/opt/nwis/data/auxdata/qw.conf.master. To set the 

default for allowed sample transactions in the “qw.conf” file, add a noncomment line that begins 

with the text “transaction_type:,” followed by one or more space characters, then one of the 

following options. 
QWDATA: Section 3.8 Option 8 – Batch Processing 

Water Quality 178 NWIS User

Option Mnemonic Behavior

update_only QWCARDSIN Only modification of existing sample records is allowed 

(including modification and addition of results).

add_only - - Only addition of new samples records is allowed.

any QWENTER Addition, deletion, and modification of sample and/or 

result records is allowed.

verify_only - - No database updates are allowed.

If the qw.conf file is incorrectly formatted or an invalid option is specified, then the default 

option is "update_only.” 

Batch file programs can also be invoked from the UNIX command line (or cron job). When this 

approach is used, the behavior options specified on the command line are used. If invoked from 

the UNIX command line and no behavior options are specified on the command line, then the 

file named “qw.conf” is consulted to determine the appropriate behavior. 

Some “tricks” for using the batch programs might be useful. 

1. Set a remark code to “X” to delete a result and all of the associated attributes. 

2. To delete value qualifier code(s), set the value qualifier code to “#” in the batch file. For 

example, to delete value qualifier codes of “aim,” the value qualifier code should be “#” 

in the batch file. A “#” in the value qualifier field will delete all laboratory value qualifier 

codes but will NOT delete field value qualifier codes (f, e, &, g, j, and k) unless you 

choose the “field+lab” option in the user-specified batch behavior mode. 

3. To delete an entire sample, enter “DELETE” in the aquifer-code field (GUNIT). 

4. If a time datum is included in a batch file, the time datum will be updated in the database, 

but the UTC sample time will not be changed. The result may not be desired, so consider 

carefully before including a time datum in a batch file. If you want to change the stored 

time, consider changing the time using Modify Sample or Results (Section 3.2).

5. When including values that require scientific notation, the following format must be 

used: ##E## for positive exponents and ##E-## for negative exponents.

Record of Actions Taken (WATLIST)

A record of the actions taken when a batch file is processed with a batch-file program is written 

to the file named watlist.yyyymmdd.hhmmss. The records created, modified, or deleted, the 

cation/anion balance (if it can be computed), and any error information generated for samples 

and results are recorded in these files. 

The first page of every WATLIST file lists the names of the input batch files, the names of the 

batch files after processing, the date and time the files were processed, the userid of the person 

who processed the batch files, any error messages resulting from checksums or file 

concatenation, the environmental and QA database numbers used during batch processed, the 

batch modes used during processing, and whether or not an ionic balance was enabled. 

The WATLIST for a sample has four main sections and information about a sample is listed in 

the following order. 

1. Sample header information (always printed)

2. Errors, messages, and reports (printed when needed) 

• Sample-level critical failures (rejected samples)

• Result-level critical failures (rejected results)

• Sample-level errors

• Result-level errors

• Sample-level updates

• Quality-assurance report 

a. Chemical verification checks

Results for parameters that are greater than defined USEPA drinking-water 

alert limits in Appendix E will be listed here. As of NWIS 4.8, a result with any 

remark code other than a less-than symbol (<), M, N, or U will be compared to 

the list of defined limits. If the result is greater than or equal to the defined 

limit, an error message will appear.

• A complete list of which verifications and validations are performed is 

available in Appendix M.

b. Cation/anion balance (printed only if the ionic-balance mode is enabled and at 

least one cation and one anion constituents are present.) Appendix L lists 

parameters used in the ion-balance table.

The first column in the table of results indicates the status of the result and has a column header 

of “*.” This one-letter code indicates what happened to that result during the batch processing. 

For result data that contain updated information, two rows will appear in this section. The first 

row contains the updated information and prints the entire row as the data are stored in the 

database with a status of “U.” Immediately following the updated row is a row with status of 

“P.”

Code Definition

N New result 

U Updated result 

D Deleted result

P Previously stored result (before update)

X Result transaction failed due to error in input data

C Calculated result

blank Result already stored and no update was made

Samples that are not processed are shown in the WATLIST file and are differentiated from 

processed samples by a blank record number field and an error message stating why the sample 

was not processed. The text “Unstored” will be printed where the record number normally 

appears if the batch verification mode is in effect (Section 3.8.4). The text “Deleted” will be 

printed where the record number normally appears if the entire sample is deleted. The WATLIST 

is automatically sorted by project code. Examples of the WATLIST output can be found in 

Appendix C. 

Rejected Samples and Results 

Samples will be rejected for the following reasons: (a) invalid format, (b) invalid agency code, 

site ID, dates, times, or medium code, (c) illogical combinations of begin and end dates and 

times, or (d) results for samples that do not already exist in the water-quality file (except menu 

options 2 and 4), and the transaction mode selected from the menu does not allow addition of 

samples. For each sample rejected due to a failure of the input data at the sample level, all results 

for the sample also are rejected. The sample and result records for the rejected samples are 

written to batch-format files identical in format to the input file. 

Result transactions will be rejected for the following reasons: (a) improper format, (b) invalid 

code for any of these attributes: parameter code, remark code, method code, or null-value 

qualifier code, (c) update for a DQI-protected result was not enabled by the batch mode selected, 

(d) addition of the result would cause more than 500 results for the sample, (e) the value is nonnumeric, (f) a null value is not accompanied by a null-value remark or null-value qualifier, (g) a 

non-null value is accompanied by a null-value remark or null-value qualifier, (h) a negative 

value for the supplied parameter code is disallowed, (i) an invalid fixed value is supplied for a 

fixed-value parameter (see Appendix B), or (j) inappropriate attributes (such as a remark code) 

are supplied with a fixed-value parameter.
QWDATA: Section 3.8 Option 8 – Batch Processing 

Water Quality 182 NWIS User

If a single result fails, other results for the same sample will be processed. For each result 

rejected due to a failure of the input data at the result level, the parent sample record is written 

along with the rejected result to batch-format files identical in format to the input file. 

If no transactions (sample or result) are rejected, no additional batch files are created. The 

rejected sample and result files can be reprocessed by initiating one of the batch input programs 

after the files have been corrected. 

The files rejected.sample.yyyymmdd.hhmmss and rejected.result.yyyymmdd.hhmmss are 

created when samples are rejected from a qwsample/qwresult batch-file pair. 

A “#” followed by a sample integer is used to insert error messages in the rejected sample and 

result files. The error message is included before the record causing the error. The format of the 

error messages in the sample file is: 

#SINT<tab>error message 

The format of the error messages in the result file is: 

#SINT<tab>Result Rejected<tab>Parameter code error message 

These error messages are treated as comments and ignored by the batch input programs. Menu 

Option 5 to review or Option 6 to edit the tab-delimited batch files will not show the error 

messages either.

data into an alternate database.

-dqi_protection yes or no

Allows you to knowingly protect or allow updates to results. If the entry is “yes” then results 

will not be overwritten if the DQI code is ARQOX. Otherwise, the results will be updated. 

-ionic_balance_rpt yes or no

Allows you to suppress the ion balance report in the watlist file. 

-custom_alerts xx, yy, all

Allows you to specify a list of custom alert limit files to validate the data against. The list can

alert limit files are located at /usr/opt/nwis/data/auxdata/qw_alert_limits.

-tab_delimited_files filename(s) 

The list of delimited files containing data to load. Only the sample filenames are to be listed. 

They must contain “sample” in their filename, as “sample” will be replaced in the search 

with “result” to locate the corresponding results file. The text “sample” and “result” in the 

pair of filenames must be in either all upper-case or all lower-case letters.

-transaction_type update_only, add_only, any, verify_only, none

Allows you to set the batch mode to update only to existing records, add only new records to 

the database, complete any transaction, or only verify the batch file being processed. Using 

the none option will copy the files and rename them “qwsample” and “qwresult.”

3.8.1 Option 1 – Enter Batch-File Data for Logged-in Samples 

This option runs qwcardsin, a program that updates sample records with sample and result 

information from tab-delimited batch-file pairs. Thus, an entry for each sample (environmental 

and QA) must already exist in NWIS. 

Generally, qwcardsin is used to enter the NWQL or other laboratories’ transferred data into 

NWIS. The user will “point” to the appropriate environmental database number. QC data will be 

separated and written to an associated QA database. 

3.8.2 Option 2 – Enter Batch-File Data for all Samples

This option runs qwenter, a program that enters or updates analytical data into NWIS from tabdelimited batch-file pairs. This program is different from qwcardsin in that a record for a sample 

does not have to be in the database for the data to be successfully processed. 

This program may be used to update existing records with USGS laboratory analytical data, 

create new records, add analytical data from non-USGS sources, and perform limited editing 

functions. Use of qwenter to create records has the potential to create unintended records instead 

of updating the intended records if there is an error in the key identification fields (site ID, date, 

time, and medium code). These erroneous records are sometimes difficult to detect and can be 

time consuming to repair. The appropriate time to use qwenter is when field crews have been 

shipping samples from the field without the opportunity to login the samples into NWIS, and a 

WATLIST is needed to review the laboratory results during the period of time when reruns are 

still possible. Situations where only new records are intended, such as loading data from another 

agency, are best handled using the user-specified batch behavior menu option using the setting 

“Transactions allowed: Only additions of new samples” as discussed in section 3.8.4. 

To appropriately use qwenter, the user will “point” to the appropriate environmental database

3.8.3 Option 3 – Reload Batch-File Data, Overriding DQI

This option runs qwcardsinxdqi, a program that updates sample records with sample and result 

information from batch files and overrides any DQI values (Appendix A, Table 9) that would 

have protected existing values from update. This program is a modification of the qwcardsin

program, so an entry for each sample (environmental and QA) must already exist in NWIS. The 

result DQI codes will default to S except for results transmitted with any other DQI code.

Generally, this program will be used to enter reloaded data from the laboratory or other largescale changes to the water-quality data. The user will “point” to the appropriate environmental 

database number. QC data will be separated and written to an associated QA database.

Some sample and result-level fields are considered “lab” fields. When “Data that can be updated: 

Lab only” is selected, data that originate with the field office cannot be updated. The following 

sample-level fields cannot be updated when “Lab only” is selected. 

Column name Description

The following result-level field cannot be updated when “Data that can be updated: Lab only” is 

selected.

field_result_cm_tx Field result comment

Additionally, some value-qualifier codes cannot be updated in “Lab only” mode, because they 

are reserved for use by the WSC’s. Finally, only results having DQI codes of S, I, P, or U are 

allowed to be updated or written in “Lab only” mode. For more information on value-qualifier 

and DQI codes, see Appendix A.

The four types of transactions below are allowed. 

1. Only updates to samples (qwcardsin). This is the same mode as when the Batch Processing, 

Option 1, “Enter batch-file data for logged-in samples” option is selected. 

2. Only addition of new samples. This is the mode used for the addition of new samples to the 

database. This option cannot be used for updating existing samples. 

3. Any transaction (qwenter). This is the same mode as when the Batch Processing, Option 2, 

“Enter batch-file data for all samples” option is selected.

4. Verification only, no transactions stored. This capability provides for a “dry run” of the 

batch program. This mode can be useful for checking data from an external source or for 

cleaning up data prior to an attempt at storage in the database. The WATLIST created when 

the program is run with verification mode has the following characteristics.

• Diagnostic messages generated from the input transactions are printed as usual, with the 

following exceptions. 

• The sample record number is reported as “Unstored.” 

• When the sample from the batch file is not currently stored: the “Number of parameters” 

stored is reported as zero and the following message is printed above the listing of results. 

===================================================================== 

VERIFICATION MODE: NO NEW RECORD CREATED.

=====================================================================

When the samples from the batch file is already stored, the “Number of parameters” printed is 

the number currently stored. The “Database Number” indicates where the matched stored sample 

was found, and the following message is printed above the listing of results.

===================================================================== 

VERIFICATION MODE: NO UPDATES STORED FOR RECORD NUMBER xxxxxxxx

=====================================================================

Rejected sample and result files are created in verification mode, but these files contain only 

those records that would have been rejected if the user had attempted to store the data. 

To compare the results to one or more user-specified alert limits, set option 6 to “Yes.” The 

following dialogue will appear:

Enter alert limit file number(s), comma separated, or "all" to use

all available files (? to search, <CR>=none): ______________________________

If “all” is selected, all valid alert limit files will be used. A list of file numbers selected is echoed 

to the screen but this list is truncated to eight file numbers. A detailed description of how to use 

the user-specified alert limit option is in Section 3.3.5.

3.8.5 Option 5 – Review Tab-Delimited Batch Files 

Option 5, Review tab-delimited batch files, is used to review tab-delimited batch input files. The 

default filenames are qwsample and qwresult, but any appropriate filenames may be entered. 

The sample and result data are combined and displayed to the terminal screen (T) or saved to a 

file after the names of the sample-level and result-level tab-delimited batch files are entered. If 

the files are displayed to the screen, you can set the number of lines displayed at one time. The 

default number of lines displayed on the screen is 24. 

Move through the records on the screen with carriage returns, and enter a “Q” to quit the review. 

The combined sample and result data also can be saved to a file (F), and you are prompted for 

the name of a file to store the formatted sample and result data. The output file format contains 

the same information as the screen display, the names of the tab-delimited batch files used, and 

the date the output file was created. The heading information shown below is present at the top 

of the file output. 

1Batch Transaction Files -- Processed: 20040520 134647 

 Sample: qwsample 

 Result: qwresult 

 

Note: If you enter a “result” filename that contains none or some, but not all of the 

corresponding results for the “sample” file, then only the matching sample and results data 

will be displayed. For example, you might try to open an edited result-level file and a nonedited 

sample-level file. A message such as this is displayed, “One or more result records with no 

sample record preceding sample: 886918.” 

An example output file is shown on the following page.

3.8.6 Option 6 – Edit Tab-Delimited Batch Files 

Option 6, Edit tab-delimited batch input files, will bring up a separate window to let the user edit 

the sample and result data with a spreadsheet-like tool similar to commercial-off-the-shelf 

spreadsheet applications, including the ability to resize and move windows. The initial batchediting window is shown in the following image. 

Drop-down menus are available for File, Edit, View, and Sort functions, and displaying the 

contents in the Results file related to the sample file. Note: If you experience problems with 

viewing the drop-down menus near the bottom of your screen, you may have to change 

your UNIX environment variables. Submenus for each of these are shown below. 

• File 

o New 

o Open 

o Save Samples and Result 

o Save Samples and Results As... 

o Exit

The program automatically recognizes similarly named, linked pairs of files with names 

containing the text “sample” and “result,” although files with other names also can be opened. 

Refer to the image below. The button for “Files of type” controls whether only filenames 

containing the text “sample” are displayed or if all filenames are displayed. In the former case, 

when a sample filename is entered or selected, the program automatically finds and opens a 

similarly named result file (by looking for similarly named file, swapping the text “result” for 

“sample”). In the latter case, the user manually identifies the filename containing the 

corresponding results. The user may change to a different directory using either of the two 

buttons adjacent to the word “Directory” at the top of the window. 
QWDATA: Section 3.8 Option 8 – Batch Processing 

Water Quality 192 NWIS User

Note: The program has no way to identify any particular file as containing valid batchformat samples or results. The user must ensure that the appropriate filename is supplied. 

Using an incorrect filename or supplying the filenames in the wrong order can cause the batch 

editor to behave in a peculiar manner.

Water Quality 193 NWIS User

Once a file has been selected, the spreadsheet cells are populated, as shown in the following 

image. 

One or more samples can be selected by “clicking” on the sample integer (SINT) cell of the 

desired sample or samples, which highlights the cell. Results for all or selected samples can be 

chosen, and the results can be displayed in a separate window as shown below. 
QWDATA: Section 3.8 Option 8 – Batch Processing 

Water Quality 194 NWIS User

Note: If a new result is added to the results file BEFORE a corresponding sample row is 

entered, the result row will not be saved. Always create the new sample row, before creating 

new result rows. 

Visibility of specific columns in either the sample or results window may be adjusted by 

selecting the “View” menu. A “tear-away” version of the “View” menu is available by clicking 

on the dashed line near the top of the expanded “View” menu. This will allow you to keep the 

column options visible on top of the sample or results windows. Show or hide columns by 

selecting the box adjacent to the column name. Selections marked with a red square are visible in 

the active window. 
QWDATA: Section 3.8 Option 8 – Batch Processing 

Water Quality 195 NWIS User

To use the “Find and Replace All” function in either the sample or result window, click “Edit” 

then “Find/Replace.” Next fill in the find and replace boxes with your desired changes. Select the 

column to search and replace by clicking on the column heading. Then click “replace all.” 

In the Results window the additional pull-down menu for “Transform” is available and contains 

the following options: 

• Transform 

o Add, 

o Subtract, 

o Multiply, 

o Divide. 

At least one cell must be selected in the Results window to select a transform option. In addition 

to selecting a transform, you must enter a “Numerical Factor,” which is the number you would 

like to add to, subtract from, multiply by, or use to divide the value in the cell you selected. For 

example, if you want to add 10 to a result value, you would select the cell, then select “Add,” 

enter “10” in the “Numerical Factor” field, and select “OK.” 

In summary, batch-file editing options in the spreadsheet include: 

• Using the mouse cursor to “Point and click” to select rows, columns, or cells; 

• Navigation from one cell to the next using the tab or arrow keys; 

• Sort columns while still retaining the matching sample integer (SINT); 

• Shortcuts are available for use within the batch editor including: 

• Ctrl-c to copy the contents of rows or cells 

• Ctrl-a to select the entire contents of a cell

• Ctrl-v to paste 

• Ctrl-left (or right) arrow to move within a cell 

• Ctrl-y to repeat the previous action

• Ctrl-x to cut the contents of cells or rows

• Ctrl-z to undo the previous action 

• Ctrl-y to redo the previous action 

• Search for a string of characters or numbers in the spreadsheet; 

• Insert or delete rows in the sample or the results spreadsheet. If a sample row is deleted, 

the corresponding rows in the results spreadsheet are also deleted. 

• Perform simple math calculations on any cell in the results table (add, subtract, multiply, 

divide) using the “Transform” pull-down menu; 

• Files are saved from the sample-level window. If the associated result-level file is open, it 

should be closed prior to attempting to save the sample-level file. 
QWDATA: Section 3.8 Option 8 – Batch Processing 

Water Quality 196 NWIS User

• Files can be saved after editing or files can be “Saved As” to give files different names. It

is important to remember to use a naming convention of “qwsample._____” because the 

corresponding result-level file will automatically be saved with the same extension; and 

• The “Exit” command can be used to exit out of spreadsheets without saving. 

3.8.7 Option 7 – Produce Tab-Delimited Batch Files 

This option is used to produce qwsample and qwresult files from the database. The format of 

these files is described in Appendix F. The program will use record numbers or agency code, 

station ID, date, time and medium code to generate the output file. This information can be 

entered from the terminal or from an existing file. The format of the optional input files is 

described in Appendix G. If you enter the record numbers interactively, the behavior used is 

described in Section 3.3.4. Records cannot be retrieved from multiple databases during a single 

retrieval. If record numbers are in the format ########db, where “db” is the database number, 

then only records from the selected database will be retrieved. You might not retrieve the records 

you expect. The output files can be specifically named or defaulted to qwsample and qwresult. 

The local “User Code” (Section 2.4.21) that is included in the qwsample file also may be 

specified in the qw.conf file. On a separate line, enter the key word “customer-code,” followed 

by one or more spaces, and then enter the default User Code. Set the User Code to the 

appropriate alphanumeric code for your Water Science Center. For example, an entry for 

Montana would look like “customer-code: MT.” If a default is not specified in the qw.conf file, 

then *UNSPECIFIED* is inserted in the User Code field.

3.9 Miscellaneous Programs

Some programs that can be used with QWDATA are available as command line prompts, but the 

programs are not available from within the QWDATA menus. The programs discussed in this 

section can be used to manipulate tab-delimited batch files and, by using a batch process, can be 

used to convert RDB files to Microsoft Excel format and adjust the date-time for stored sample 

records.

3.9.1 Program to Concatenate Tab-Delimited Batch Files (qwcat)

Initiate the program to concatenate multiple pairs of “qwsample” and “qwresult” files into a 

single file pair by typing the following at the command line prompt:

qwcat [-q] file1 [ file2 .. fileN ] .

Where: 

“-q” is an optional argument that causes suppression of some of the messages written by 

the program, and

“file1 file2 fileN” is a mandatory list of filenames for NWIS-QW tab-delimited sample 

files or a shell-interpreted wildcard string. The list might contain only one filename, 

which is useful for validating the contents of the batch. The program will determine the 

filename of each matching NWIS-QW result file by replacing the text “sample” in the 

sample filename with the text “result.”

An example of this command is: 

qwcat rejected.sample* , 

where “rejected.sample*” is a shell-interpreted wild-card string that matches all files in the 

current directory that begin with the text: “rejected.sample.”

Output is written to the current directory in files named “qwsample.cat” and “qwresult.cat.” Any 

existing files of these names are renamed using a current date-time suffix. The 

qwsample.cat/qwresult.cat files will have sample integers renumbered to 1, 2, 3, etc. The 

qwresult.cat file will include the results ordered by the parameter code within each sample. The 

following errors can cause the program to stop. 

• No write access to the current directory.

• Inability to rename preexisting output files: “qwsample.cat” and “qwresult.cat.”

• Inability to open files in temporary directory (/tmp or $TMPDIR).

• Invalid optional argument. 

• No valid qwsample filename specified.
QWDATA: Section 3.9 Miscellaneous Programs

Water Quality 198 NWIS User

The following errors can cause the program to stop processing the batch files.

• qwsample filename does not contain the text “sample.”

• qwsample or qwresult files do not exist in current directory. 

• qwsample or qwresult files are not readable by current userid.

• qwsample or qwresult files do not contain text in first 10 bytes. 

• qwsample records with duplicative sample integers.

• qwresult records with duplicative combination of sample integer and pcode. 

• qwresult record with sample integer not present in qwsample file. 

The following can cause unexpected and undesirable behavior. 

• Duplicative command-line specification of the same qwsample filename (eg. with 

wildcards) is silently reduced to one inclusion. 

• Batch-file pairs may not be processed in the order entered; they are processed in ASCII 

sort order by qwsample filenames.

• qwsample records are not sorted within each file; they are added in order of the 

qwsample file.

• qwresult records are primarily processed in the same order as the qwsample records and 

secondarily sorted using ASCII sort order by parameter code.

• qwsample and qwresult zero-length records are silently ignored.

• If records exist in qwsample or qwresult files without tab delimiters, they are counted, but 

ignored. The count of these records is printed. 

• qwsample record with sample integer not matching qwresult records is included. The 

count of such records is printed. 

• qwsample and qwresult records with too few tabs are padded (to the right) with empty 

fields delimited with tabs. The count of such records is printed. 

• Program does not track orphaned sample/result messages and they are ignored. 

• Including input files that contain “*.cat” in the filename.

3.9.2 Program to Subset Tab-Delimited Batch Files (qwsplit)

You can initiate the program to subset one or more tab-delimited batch-file pairs using project 

code and (or) station-identification number by using the following: 

qwsplit [-p fileP] [-s fileS] file1 [ file2 .. fileN ] . 

Where:

“ -p fileP” specifies an optional filename that provides data on how to split the data by 

project,

“-s fileS specifies” an optional filename that provide data on how to split the data by 

station, and 

“file1 file2 .. fileN” is a mandatory list of one or more tab-delimited batch filenames of 

sample data. The matching result filenames are assumed to be the same, except the 

filename text “sample”" is altered to “result.” 

An example of this command is: 

qwsplit rejected.sample . 

If neither a “-p file” nor an “-s file” is supplied, then the program will use all of the project codes 

found in the qwsample files to subset the data. One pair of subset-data files will be created for 

each unique project code found in the data. Output files will be named according to the pattern 

“qwsample.PROJECT” and “qwresult.PROJECT,” where “PROJECT” is a project code found in 

the data. Data found in the input file(s) without a project code will be associated automatically 

with the project code “misc,” and thus will be written to files named “qwsample.misc” and 

“qwresult.misc.” 

You can obtain more control over how the data are split by using one or both of the optional 

split-specification files. Project-split specifications may be supplied in a file named after “-p” on 

the command line, as in: 

qwsplit -p qwsplit.projects rejected.sample . 

Likewise, station-split specifications may be supplied in a file named after “-s” on the command 

line. Both the “-p” and “-s” command-line options may be used; however, the project-split 

specifications have precedence over the station-split specifications when both apply to the same 

sample.

The split-specification files consist of records of which projects or stations belong in separate 

output files and how those files should be named. In a project-split file, a project-identification 

number is specified, followed by one or more blank (or whitespace) characters, followed by a 

filename component. Additional projects may be specified on subsequent lines in the file. The 

same project should not be specified more than once in the file; however, multiple projects may 

be assigned to the same filename component. Filename components should not contain blanks 

(or shell metacharacters, such as “*” or “?”).
QWDATA: Section 3.9 Miscellaneous Programs

Water Quality 200 NWIS User

The following is an example project-split file.

404000300 bds

 00300 bds

 404039000 jim 

39000 jim

This file would split any “qwsample” records with project code of “404000300” or project code 

“00300” into a file named “qwsample.bds.” New data will be concatenated onto the end of an 

existing file. Similarly, “qwresult” records associated with either of these project codes will be 

concatenated to the end of a file named “qwresult.bds.” All sample and result records with a 

project code not identified in the project-split file are appended to the files named 

“qwsample.misc” and “qwresult.misc.”

The station-split file is prepared in the same manner, except that station-identification numbers 

are presented where project codes appear in the above example.

The following errors can cause the program to stop. 

• No write access to the current directory.

• No filename specified afterwards when “-p” or “-s” are on the command line.

• An invalid (unknown) command-line option. 

• No qwsample filename is given on the command line. 

• Station-split or project-split file specified cannot be opened.

• Inability to concatenate data to a temporary qwsample or qwresult file.

The following errors can cause the program to stop processing the batch files.

• qwsample filename does not contain the text “sample.” 

• qwsample or qwresult files do not exist in current directory. 

• qwsample or qwresult files are not readable by current userid.

• qwsample or qwresult files do not contain text in first10 bytes. 

• qwsample records with duplicative sample integer exist.

• qwresult records with duplicative combination of sample integer and pcode. 

• qwresult record with sample integer not present in qwsample file. 
QWDATA: Section 3.9 Miscellaneous Programs

Water Quality 201 NWIS User

The following can cause unexpected and undesirable behavior. 

• Duplicative command-line specification of the same qwsample filename (e.g. with 

wildcards) is silently reduced to one inclusion. 

• Warning printed if station-split or project-split file contains records where split data are 

duplicative or incomplete. 

• Zero-length qwsample, qwresult, or split-file records are silently ignored.

• Warning printed of the count of ignored untabbed sample and result records. 

• All blanks are removed from project and station-id found in sample records prior to 

applying subsetting rules. 

• Because the program qwcat is used by qwsplit, errors that may cause qwcat to operate 

incorrectly also apply to qwsplit. 

3.9.3 Program to Convert 1-and-* Card Batch Files to Tab-Delimited Batch Files (star2pair)

This program is not part of a usual NWIS installation, and this documentation is included for 

users’ convenience. The program is available by request.

This program will convert a 1-and-* card batch file to tab-delimited batch files when the 

following command is entered: 

star2pair < input file , 

where input file is the name of the 1-and-* card batch file to convert. 

The program creates tab-delimited files named “qwsample” and “qwresult.” If these files exist in 

the working directory, they are overwritten. Note: All 1-and-* card batch files must be 

converted to tab-delimited batch files beginning with release NWIS 4.8, because the option 

to process 1-and-* batch files has been removed.

Some things you should know about this program are: 

• the program does not verify the input data; 

• the program does syntactically verify the *-record and the X-record; 

• when a syntax failure occurs, the program prints an error message, the line number, and 

contents of the offensive input record and then continues; 

• provides date conversion, case translation, and blank removal; 

• provides syntactical conversion of result deletions and null-value qualifiers; and

• provides special handling for the nonstandard syntax used by the NWQL for end-of-file 

and sample laboratory-identification number (such as P99998).

3.9.4 Program to Convert RDB Output Files to Excel Files (rdb2excel)

This package of program and documentation are available by request.

This program is helpful for preparing data retrievals for internal or external users. The program 

will convert an RDB file to an Excel -workbook file (see version compatibility below) when the 

following command is entered:

rdb2excel rdb_file_name excel_file_name , 

where “rdb_file_name” is the input file and “excel_file_name” is the output file.

The functions of this program are: 

• include RDB comments (in blue) above the column headings;,

• include column names (in red) above the first line of data; 

• convert RDB dates to Excel dates, inferred from column-definition specification of [Dd] 

and actual field length of 10 or less; 

• convert RDB date-time to Excel date-time, inferred from column-definition specification 

of [Dd] and actual field length greater than 10; 

• convert RDB text fields to Excel text, inferred from column-definition of [Ss] or "" 

(null);,

• convert RDB numeric fields to Excel numeric data, inferred from column-definition 

specification of [Nn]; 

• convert RDB missing values to Excel missing values and note that one or more blanks is 

-not- missing;,

• set column widths using either the wider of column-definition specification or the

3.9.5 Programs for Managing the Display of Water-Quality Data on NWISWeb 

Water-quality data can be updated on NWISWeb (http://waterdata.usgs.gov/nwis) by using one 

of two processes: interactive updates or automated processes to upload data on a regular 

schedule. With either process, you have the option to push a full copy of the NWIS data to 

NWISWeb, push only the most recent updates, or push all data for one or more sites. Regardless 

of the method chosen by your WSC, it is advised that you periodically run the preparation steps 

outlined below to help ensure that internal-use-only samples, such as quality-control samples, 

are not included on NWISWeb and that all NWQL corrections have been applied. 

In NWIS, settings at the site, sample, and result levels can be used to prevent certain waterquality data from being displayed on NWISWeb. Data managers can use these settings to 

indicate that data are either internal-use only or proprietary. At the site level, the site Web code 

can be used to suppress all data for a site from being displayed on NWISWeb. Details are in the 

Ground-Water Site Inventory documentation (Chapter 2; Section 1.39). 

The analysis status code in QWDATA can be used to suppress a specific sample from being 

displayed on NWISWeb. Details about how to change this field are in Chapter 3.2.3 and Chapter 

3.7.5. To suppress specific results from being displayed on NWISWeb, use the Data Quality 

Indicator (DQI) code. Details about how to change this field are in Chapter 3.2.3 and Chapter 

3.7.6. 

Preparation Steps 

• Please ensure the NWIS reference lists are up to date. 

• Complete all National Water Quality Lab (NWQL) data reloads before proceeding. Load all 

NWQL reloads in the WSC NWIS database before making the NWISWeb retrievals. 
QWDATA: Section 3.9 Miscellaneous Programs

Water Quality 204 NWIS User

• Optional Data Check 

A program called qwwebreport (Section 3.9.5.1) has been developed to report which samples 

and results will be excluded from the NWISWeb retrieval. This program is designed to help 

the QW Specialist determine if currently excluded data are properly coded in NWIS. Also, 

this report can be used to screen for data that would be erroneously excluded, enabling 

corrections to be made prior to the retrieval program execution. This program should be run 

before the NWISWeb retrievals are made.

Retrieval Steps 

The program qwreloadout retrieves water-quality data from QWDATA and refers to transaction 

logs to incrementally update data on NWISWeb. The commands described in the retrieval 

options invoke this program and send the output to the NWISWeb databases. The process of 

retrieving a full copy of the NWIS water-quality database by using qwreloadout requires little 

personnel time, but it may require several hours of machine time to complete, so you may want 

to make the retrieval at the end of the day. An NWISWeb program called retrieve_qw_data uses 

the output from qwreloadout to transfer the retrieved water-quality data from the NWIS host to 

the NWISWeb databases.

The retrieval commands retrieve water-quality data from NWIS and use these records to update 

the water-quality data in the internal aggregated NWISWeb database and the public NWISWeb 

database. All data in the NWIS databases will be retrieved up to and including the current day. 

You may choose to update the entire database or update only selected sites. 

The following water-quality records will not be displayed on NWISWeb. 

• Water-quality data not stored in NWIS database 01 

• Samples for sites where the site-web flag is not “Y” 

• Samples where the analysis-status code is “I” or “P” 

• Samples without a corresponding SITEFILE entry (orphaned records) 

• Results with a DQI of {I,O,P,Q,U,X} 

• Null results with null-value qualifiers; however, null results with remarks of U,M 

or N are displayed on NWISWeb 

• Parameter code in (71995–-71998) and result_va = 4941 

• Parameter code = 72005 and result_va in (44,46,69,70) 

• Parameter codes where the parm_public_fg = N 
QWDATA: Section 3.9 Miscellaneous Programs

3.9.5.1 qwwebreport 

The program qwwebreport lists the record number of all samples or samples that have results 

that will be excluded from the file created by the program qwreloadout. Specific conditions that 

result in exclusion of a sample or result within a sample are described in Section 3.9.5. To 

determine if the samples or results excluded from the NWISWeb dataset are coded properly, 

review the output from qwwebreport before running retrieve_qw_data . Guidance for reviewing 

the output is below. 

To execute the program, type:

qwwebreport > output.filename . 
QWDATA: Section 3.9 Miscellaneous Programs

Water Quality 206 NWIS User

The file “output.filename” is your choice of a filename, and this file will contain a report of 

samples and results that will not be included in the output from the program qwreloadout. Note: 

The qwwebreport program is executed using the user's current NWIS data base setting. To 

create a report for another database, select the desired database number before executing the 

software again. The database number can be specified as described in Section 3.7.1 of 

QWDATA documentation. An example of the output from this program is in Appendix C.

Code Name Description

A Not determined The sample type was not recorded.

B Other QA Other quality-assurance samples collected for specific purposes 

other than regular samples.

H Composite (time)

Composite analyses represent samples collected over a period of 

time. Compositing minimizes sampling variability or analytical 

costs for sample group. Concentration and constituent load are 

assumed relatively constant over the composited time period. Or, 

concentrations are known to be changing and the composite sample 

is intended to characterize the event.

1 Spike

A sample to which known quantities of specific (often organic) 

analytes have been added. Spiked samples are used to monitor the 

stability of the analytes from the time of the spike to the time of the 

analysis and to determine the potential bias introduced by the 

sample matrix. The measured and known concentrations are used to 

compute percent recovery for each analyte. Recovery rates are 

compared to potential factors, especially constituent concentrations, 

to discover causes of variability and (or) bias.

2 Blank

A blank sample is prepared from a reference material where none of 

the analytes of interest are present in detectable quantities. Blank 

samples are used to determine if environmental samples have been 

contaminated during the data-collection process. Detection of an 

analyte in a blank sample that is absent in the blank-source sample 

indicates bias due to contamination.

3 Reference

Reference samples are prepared from an aliquot of reference 

material. Reference samples are introduced into the data-collection 

process at various measurement stages to determine bias and 

variability of the measurement system. Individual sample results are 

compared to most probable values. Reference-sample results can be 

used to determine if an analytical process is within expected control 

limits and whether a project's data-quality objectives are met.

4 Blind

A sample submitted for analysis whose known composition is 

unknown to the analyst. A blind sample is prepared from a 

reference material. A blind sample is a particular instance of the 

reference sample where the identity of the sample is not revealed to 

the analyzing entity. Blind samples are used to measure the 

performance of an analytical system, results of more than one 

laboratory, more than one analytical method, or the consistency of 

the same laboratory and method over time.

5 Duplicate

A two-sample instance of a replicate group. The preferred 

terminology for this type of sample is replicate. One sample is an 

environmental sample. The companion sample is a quality-control 

sample.
4.1 Appendix A. Codes Used in Water-Quality System

Water Quality 215 NWIS User

Code Name Description

6 Reference material

Reference material is a general term for a homogenous substance 

generally prepared by laboratories or chemical suppliers where the 

concentration of one or more constituents is known. Referencematerial samples provide the baseline analytical results for 

comparison to reference samples. The reference-material sample 

results are the generally accepted analytical most probable values 

(MPV). Field users will normally submit reference samples, not 

reference material samples.

7 Replicate

A member of group of samples collected in a manner such that the 

samples are thought to be essentially identical. Samples where 

some part of the measurement process was altered (such as analysis 

by different laboratories or methods) are termed irreplicates. 

Irreplicates should not be identified as replicates. One group 

member is an environmental sample and the remaining group 

members are quality-control samples. Replicate samples are used to 

describe the variability measurement.

8 Spike solution 

A solution with one or more well established analyte 

concentrations. A spike solution is a specific type of a liquid 

reference material that is added in known quantities to a known 

volume of another sample to form a spiked sample. Results for 

spike-solution samples are stored to describe the known 

concentrations of the analytes in the spiking solution lot. Spikesolution results are interpreted in conjunction with spiked sample 

results during the computation of the percent recovery.

9 Regular Sample taken from the environment collected to represent the 

conditions at a particular place and time.

Table 7. Primary use of site codes (site level).

Code Description Definition

A Anode 

Anode is a hole used as an electrical anode. Include in this 

category wells used solely to ground pipelines or electronic 

relays and other installations.

C Standby emergency supply 

Standby emergency supply refers to a water-supply source 

that is used only when the principal supplier of water is 

unavailable.

D Drain Drainage refers to the drainage of surface water 

underground.

E Geothermal 

Geothermal well is a hole drilled for geothermal energy 

development. Use this category for “dry” geothermal wells 

or wells into which water is injected for heating. For “wet” 

geothermal wells, through which water is withdrawn, use 

“W - withdrawal of water” for the use of site, and “E - 

power generation” for the primary use of water.

G Seismic

Seismic hole is one drilled for seismic exploration. If it has 

been converted to water supply, use “W – Withdrawal of 

water” for the use of site.

H Heat

Heat reservoir refers to a well in which a fluid is circulated 

in a closed system. Water is neither added to, nor removed 

from, the aquifer.

M Mine Mine includes any tunnel, shaft, or other excavation 

constructed for the extraction of minerals.

O Observation

Observation well is a cased test-hole or well, drilled for 

either water-level or water-quality observations. Do not use 

this category for an oil test hole or water-supply well used 

only incidentally as an observation well.

P Oil or gas well

Oil or gas well is any well or hole drilled in search of, or for 

production of, petroleum or gas. It includes any oil or gas 

production well, dry hole, core hole, injection well drilled 

for secondary recovery of oil, etc. An oil test hole converted 

to a water-supply well should be classified as withdrawal 

(W).

R Recharge

Recharge site is a site constructed or converted for use in 

replenishing the aquifer. An irrigation well used to return 

water to the aquifer during nonpumping periods is a well 

for withdrawing water, not a drainage or recharge well. Use 

this category for wells that are used to return water to the 

aquifer after use, such as those for returning air 

conditioning water.

S Repressurize

Repressurize refers to pumping water into an aquifer in 

order to increase the pressure in the aquifer for a specific

purpose; for example, water flood purposes in oil fields.
4.1 Appendix A. Codes Used in Water-Quality System

Water Quality 218 NWIS User

Code Description Definition

T Test

Test hole is an uncased hole (or one cased only temporarily) 

that was drilled for water or for geologic or hydrogeologic 

testing. It may be equipped temporarily with a pump in 

order to make a pumping test, but if the well is destroyed 

after testing is completed, it is still a test hole. A core hole 

drilled as a part of mining or quarrying exploration work 

should be in this class.

U Unused 

An unused site is an abandoned water-supply site or one for 

which no use is contemplated. At an abandoned farmstead, 

a well originally used for domestic purposes may be classed 

as unused, even though it is equipped with a pump. 

Similarly, a stock well with a pump may become unused 

when a pasture or corral is put into cultivation. An irrigation 

well that is not equipped with a pump, nor used because the 

yield is too low or the water is too mineralized, belongs in 

this class.

V Withdrawal/Return 

Groundwater sites that are used to both withdraw and inject 

water to a well, such as an irrigation well used to return 

water to the aquifer during nonpumping periods.

W Withdrawal of water

Withdrawal of water refers to a site that supplies water for 

one of the purposes shown under use of water. It includes a 

dewatering well, if the dewatering is accomplished by 

pumping groundwater.

X Waste disposal

A waste-disposal site is one used to convey industrial 

waste, domestic sewage, oil field brine, mine drainage, 

radioactive waste, or other waste fluid into an underground 

zone. An oil test or deepwater well converted to waste 

disposal should be in this category.

Z Destroyed

A destroyed site is one that is no longer in existence. The 

casing of most destroyed wells will be pulled, but some 

may be plugged or filled. Do not use this category for an 

abandoned site that merely is not in use.
4.1 Appendix A. Codes Used in Water-Quality System

Water Quality 219 NWIS User

Table 8. Primary use of water codes (site level).

Code Description Definition

B Bottling Bottling refers to the storage of water in bottles and use of the water for 

potable purposes (see Medicinal).

C Commercial

Commercial use refers to use by a business establishment that does not 

fabricate or produce a product. Filling stations and motels are examples 

of commercial establishments. If some product is manufactured, 

assembled, remodeled, or otherwise fabricated, use of water for that 

plant should be considered industrial, even though the water is not used 

directly in the product or in the manufacturing of the product.

D Dewater

Dewatering means the water is pumped for dewatering a construction or 

mining site or to lower the water table for agricultural purposes. In this 

respect, it differs from a drainage well that is used to drain surface 

water underground. If the main purpose for which the water is 

withdrawn is to provide drainage, dewatering should be indicated even 

though the water may be discharged into an irrigation ditch and 

subsequently used to irrigate land.

E Power Power generation refers to use of water for generation of any type of 

power.

F Fire

Fire protection refers to the principal use of the water and should be 

indicated if the site was constructed principally for this purpose, even 

though the water may be used at times to supplement an industrial or 

defense supply, to irrigate a golf course, fill a swimming pool, or for 

other use.

H Domestic

Domestic use is water used to supply household needs, principally for 

drinking, cooking, washing, and sanitary purposes, but including 

watering a lawn and caring for a few pets. Most domestic wells will be 

at suburban or farm homes, but wells supplying small quantities of 

water for domestic purposes for one-classroom schools, turnpike gates, 

and similar installations, should be in the domestic category.

I Irrigation

Irrigation refers to the use of water to irrigate cultivated plants. Most 

irrigation sites will supply water for farm crops, but the category should 

include wells used to water the grounds of schools, industrial plants, or 

cemeteries, if more than a small amount of water is pumped and that is 

the sole use of the water.

J Industrial 

(cooling)

Industrial cooling refers to a water supply used solely for industrial 

cooling.

K Mining Mining refers to a water supply used solely for mining purposes.

M Medicinal

Medicinal refers to water purported to have therapeutic value. Water 

may be used for bathing and (or) drinking. If use of water is mainly 

because of its claimed therapeutic value, use this category even though 

the water is bottled.
4.1 Appendix A. Codes Used in Water-Quality System

N Industrial 

Industrial use is within a plant that manufactures or fabricates a product. 

The water may or may not be incorporated into the product being 

manufactured. Industrial water may be used to cool machinery, to 

provide sanitary facilities for employees, to air condition the plant, and 

to irrigate the ground at the plant.

P Public supply 

Public Supply use is water that is pumped and distributed to several 

homes. Such supplies may be owned by a municipality or community, a 

water district, or a private concern. In most States, public supplies are 

regulated by departments of health that enforce minimum safety and 

sanitary requirements. If the system supplies five or more homes, it 

should be considered a public supply; if four or less, classify use as 

domestic. Water supplies for trailer or summer camps with five or more 

living units should be in this category, but motels and hotels are 

classified as commercial. Most public supply systems also furnish water 

for a variety of other uses, such as industrial, institutional, and 

commercial.

Q Aquaculture Aquaculture refers to a water supply used solely for aquaculture, such 

as fish farms.

R Recreation

Recreation refers to water discharged into pools (or channels which are 

dammed downstream to form pools), for swimming, boating, fishing, 

ice rinks, and other recreational uses.

S Stock Stock Supply refers to the watering of livestock.

T Institutional 

Institutional refers to water used in the maintenance and operation of 

institutions such as large schools, universities, hospitals, rest homes, or 

similar installations. Owners of institutions may be individuals, 

corporations, churches, or governmental units.

U Unused 

Unused means water is not being removed from the site for one of the 

purposes described above. A test hole, oil or gas well, recharge, 

drainage, observation, or waste disposal well will be in this category. 

Do not u“off season” or temporary periods of nonuse. The use of water 

from a newly constructed site should be considered as the use for which 

it is intended even though it may not yet be in use when inventoried.

Y Desalination

Desalination refers to water used in a desalting process whereby 

dissolved solids are removed to make water potable or suitable for other 

uses. Enter the type of use of the desalinated water in the next column, 

“Secondary Water Use.”

Z Other (explain in 

remarks) Other refers to miscellaneous uses not included in the listed categories.

Report 

level 

code

Definition Description

MRL Minimum Reporting Level

Smallest measured concentration of a constituent that can be 

reliably measured using a given analytical method (Timme, 

1995).

MDL Method Detection Limit

Minimum concentration of a substance that can be measured 

and reported with a 99% confidence that the analyte 

concentration is greater than zero. It is determined from the 

analysis of a sample in a given matrix containing the analyte 

(U.S. Environmental Protection Agency, 1997).

LT-MDL Long-Term Method 

Detection Limit

A detection level derived by determining the standard 

deviation of a minimum of 24 MDL spike sample 

measurements over an extended period of time. LT-MDL data 

are collected on a continuous basis to assess year-to-year 

variations in the LT-MDL.

LRL Laboratory Reporting Level

Equal to twice the yearly-determined LT-MDL. At the LRL, 

the probability of a false negative is less than or equal to 1 

percent. The reporting level is set equivalent to the LRL when 

an analyte is not detected in a sample. (Formerly referred to as 

Non-Detection Value (NDV)).

IRL Interim Reporting Level

A temporary reporting level used for new or custom schedules 

when LT-MDL data are unavailable and a LRL has not yet 

been established. 

SSMDC Sample-Specific Minimum 

Detectable Concentration

A reporting level that varies for each sample; primarily used in 

radiochemical analyses. Radiochemical measurements are not 

typically censored by the laboratory.

SSLC Sample-Specific Critical 

Level

The ssLc is the calculated and reported value below which the 

rad result is considered a non-detect (see Office of Water 

Quality Technical Memorandum 2008.06).

Explanation of fields in file 

Parameter code: five-digit parameter_cd

Calculated parm flag: Y/N flag to indicate if this is a calculated parameter code

MEQ factor: multiplication factor to convert parameter value to milliequivalents per liter

Ion type code: A one-character code that indicates the type of ion; “c” indicates a cation and “a” indicates an anion. 

Ion code: These are the commonly used ions in the ion balance. Upper and/or lower case is acceptable.

Cation codes (and definition)

Ca (calcium)

Mg (magnesium) 

Na (sodium) 

K (potassium)

Fe (iron) 

Mn (manganese) 

H_ion (hydrogen ion) 

Anion codes (and definition)

Cl (chloride) 

SO4 (sulfate) 

F (fluoride)

ALK (alkalinity; includes acid neutralizing capacity (ANC)) 

NOx (includes nitrate, nitrite, nitrite plus nitrate) 

Group code: For alkalinity (ALK) codes and nitrogen (NOx) codes, the group code will be used to define the hierarchy 

within that ion code. The group codes are:

ALK codes:

Bicarb (bicarbonate) 

Carb (carbonate) 

Hydrox (hydroxide) 
4.3 Appendix C. Output Examples

NOx codes:

NO2 (nitrite)

NO3 (nitrate)

NO2+NO3 (nitrite plus nitrate) 

For nonstandard ion codes that are not listed above, the user supplies an ion code up to 5 characters long and a group up 

to 10 characters long

Ion Row number: Indicates the order of the row in which this ion appears in the ion balance table, if present.

Ion Preference number: Indicates the hierarchy of the ion (lower numbers for the same ion code are preferentially 

selected).

Group Preference number: Indicates the hierarchy of the ions within a group (lower numbers for the same ion code and 

ion-group code are preferentially selected). 

Major Ion Flag: Indicates if this parameter code is to be considered a major ion; values are “Y” for major ion, “N” for 

minor ion.

4.4 Appendix D. Calculated Parameters 

Water Quality 314 NWIS User

4.4 Appendix D. Calculated Parameters

The NWIS QWDATA system will produce calculated results during output (qwdata-4) for bysample-layout retrievals when a calculated parameter or “CALCV” is specified or for by-resultlayout retrievals, unless specifically excluded by the user's retrieval options. These calculated results 

are computed using system-defined algorithms that use the stored results for related parameters. 

Some algorithms perform simple unit conversions, others compute sums or differences among related 

constituents, and a few perform complicated chemical logic computations. 

The operational steps of the algorithms are stored in an NWIS reference table and are updated 

periodically. The contents of the reference table can be listed using a “Support Files” menu option 

(qwdata-6-7). The following UNIX command may be used to list the parameters with algorithms 

(substitute the appropriate database name for nwisdb). 

tsql nwisdb "select distinct a.parm_cd, parm_ds from parm a, alg b 

where a.parm_cd = b.parm_cd"

Many of the algorithms optionally can employ one of several candidate parameters within the 

calculation. The plethora of different pathways through the algorithms makes documentation of 

each algorithm complex, and sometimes makes it difficult to understand how a particular 

calculated result was determined.

The QWDATA system provides a capability to produce a “trace” of all the algorithm 

computational steps that were performed during a retrieval. The trace output can be used to 

ascertain how the software produced each calculated result.

The QWDATA algorithm-processing software performs computations using a “stack” of results. 

This technique, often referred to as “Reverse Polish Notation” (RPN), is a mechanism for 

stacking up intermediate results so they can be used in subsequent computations. When results 

are entered or computed, the size of the stack of intermediate results stays the same, grows by 

one, or shrinks by one, as required by the operations being performed. Each step will involve one 

or two of the most recently processed results. The QWDATA algorithm stack includes a remark 

code, value, and data-quality indicator (DQI) code for each entry. 

Procedure to Trace Algorithms

1. Set environment variable: At the UNIX “shell” command prompt, set the environment 

variable named QWTRACEALG to the name of the file to contain the trace output. The 

syntax for setting an environment variable depends on the UNIX shell. If you do not 

know which shell you are using, type the following: 

echo $SHELL . 
4.4 Appendix D. Calculated Parameters 

Water Quality 315 NWIS User

various UNIX shells.

[Do NOT put these commands into UNIX login scripts.]

csh (C-shell) setenv QWTRACEALG 

filename.gz unsetenv QWTRACEALG tcsh (TENEX C-shell) 

Run retrieval: Use one of the tabling options in Output menus (qwdata-4) to produce the 

desired retrieval. In addition to the output file generated by the retrieval, a compressed text file 

with a trace of all the computations performed will be written to the pathname specified by the 

trace environment variable. (The batch-entry and data-verification menu options can also 

produce trace output that shows the computational steps for the calculated parameters that appear 

on the WATLIST report.) 

2. Clear environment variable: Use an appropriate “clearing environment” command 

(table 1) to stop generating trace output during subsequent QWDATA retrievals.

3. Interpret trace output: Uncompress and inspect the contents of the algorithm-trace file. 

The following UNIX commands in a pipeline will display the trace-file contents to the 

screen page-by-page. 

gzcat filename.gz | more
4.4 Appendix D. Calculated Parameters

The trace output consists of a header that identifies the QWDATA program and run date. Each 

computation is identified with a record number, database number, and the computed parameter. 

Then, the computational steps are listed in the order executed. Each step shows the algorithm 

operator (table 2), and (depending on the operator) an operand and textual comment, along with 

the stack contents after the step was performed.

Stack operators

Push 

Put a stored parameter result onto the stack.

If the result is not found, DQI is Q or X, or value is null: a 

missing result is placed on the stack. 

+1 result

ReqPush 

Put a stored parameter result onto the stack.

If the result is not found, DQI is Q or X, or value is null: 

abort the computation. 

+1 result

PushUncen

s 

Get an uncensored stored parameter result.

If the result is not found, DQI is Q or X, or value is null: a 

missing result is placed on the stack. If the remark is 

“<”:the result is set to an unremarked zero. Otherwise, the 

stored result is placed on the stack.

Retain either the lower- or upper-stack entry, and remove 

the other one. 

If lower entry is null or missing: output the upper entry. 

If both entries are null or missing: output missing. 

If one entry is a constant and the other entry measured: 

used the measured result. 

If both entries are non-null and non-missing: select based 

on remark hierarchy—blank, S, A, E, R, <, >, V. 

If both entries are non-null and nonmissing and tied remark 

hierarchy: select based on DQI hierarchy. Measured values 

are always preferred versus constant values, which are 

preferred only to missing values. 

If both entries are non-null and nonmissing and tied remark 

and DQI hierarchy: select the non-zero entry. 

Otherwise: select the upper-stack entry. 

-1 none 

Missing value operators

are missing. 0 none 

missing<0 Reset negative lower-stack result to missing. 0 none 

missing= Replace missing lower-stack result with the specified 

operand, with DQI=R and no remark. 0 float 

< Set lower-stack result to missing if less than upper result. -1 none 

(The “lower-stack result” refers to the result most recently placed on the stack. The “upper-stack 

result” refers to the result placed on the stack prior to the lower-stack result. Any result with a 

DQI of “Q” or “X” (reviewed and rejected) is treated as missing. Any operation that generates an 

overflow, an underflow, or an undefined result places a missing value on the stack. If the 

operator requires one operand (eg. ln) and the operand is a missing result or a null-valued result, 

then the output of the operation is a “missing” result. If an operator requires two operands to 
4.4 Appendix D. Calculated Parameters

complete the operation, but either operand is missing or null-valued, the result from that operator 

is a “missing” result. “Effect on Stack” indicates the addition(+1) or removal(-1) of a value on 

the stack.)

Footnotes: Operations that involve a result(s) with a less-than or greater-than remark code(s) 

(“<” or “>”) follow rules that govern inequalities. Operations involving two results not qualified 

with inequality-remark codes yield a result with the remark code that is first in the hierarchy: (V, 

R, E, A, S, or blank). Operations involving two results yield the DQI code that is first in the 

hierarchy: (X, P, O, U, Q, I, S, A, R, or #), except as noted above.

4.5 Appendix E. EPA Drinking-Water Alert Limits

Parameter codes that are allowed for new data entry are compared to the EPA primary and 

secondary drinking water standards. Parameter codes that match any of the EPA regulated 

constituents are listed in this table and are included in the NWIS alert limit file. Exceptions are 

parameters with names that indicate the results are calculated, estimated by regression 

parameters, or are constituent loads.

In some cases, a parameter may represent one or more alert limits (e.g. nitrate + nitrite) or may 

represent one constituent in an EPA standard that has multiple constituents (e.g. chloroform, 

which is a component of the EPA's total trihalomethane standard). The NWIS alert in these cases 

is the greater of the applicable EPA standards. 

[MCL, maximum contaminant level; MRDL, maximum residual disinfectant levels; TT, 

treatment technique; SDWR, secondary drinking water regulations]

4.6 Appendix F. Format for Batch Input of Data

The batch-file format for input of data into the water-quality system was established in NWIS 

4.1. The previous format used “1 and * card” images (See Open-File Report 89-617, p. 4–7 to 4–

9, for a description). The format uses two tab-delimited files. One file contains sample-level 

information including a sample integer (SINT) that is used only to link file records between the 

two files. The second file contains the results and all of the result-level attributes. In the case of 

null values, the tabs must be provided (i.e., <TAB><TAB>). For all fields except value 

qualifiers and null-value qualifiers, entries will be changed to uppercase during the batch entry 

process. Examples are included in this appendix as a reference for those users who will be 

entering data by batch.

4.12 Appendix L. Parameters Used in the Standard Ion-Balance Table 

Water Quality 662 NWIS User

4.12 Appendix L. Parameters Used in the Standard Ion-Balance Table

Note: This table lists the parameters that can be included in an ion-balance table by NWIS. The 

parameters listed under each ion code are ordered with the most preferred parameter first. The 

concentration of each selected parameter result is multiplied by the Factor to convert to 

milliequivalents per liter before inclusion in the ionic balance. If an ion does not have results for 

any of the listed parameters, then one result from each of the subsequent ion codes preceded by 

an ellipsis (...) is summed to compute the value used for that ion. For example, if none of the 

parameters listed for Alkalinity are present for the sample, then the Alkalinity contribution is 

computed from the most preferred result for each of HCO3, plus CO3, plus OH. The software 

requires at least one anion and one cation before a balance will be produced. The parameter 

00191—Hydrogen Ion will be automatically calculated from stored result values (when needed 

results are present for the algorithm) for inclusion in the ion-balance table. Other parameters, 

such as 00618—Nitrate, will not be calculated in the standard ion-balance.

[NOTE: used as null value indicator in data entry screens]

/ Move back one field

/x Continue at item number x

/+x Move forward (x) items, default x is 1

/-x Move back (x) items, default x is 1

/@ Continue at item with string @ in label

/p Back up to previous page (screen)

/n Advance to next page (screen)

/d Delete current parameter

/a Insert new parameter

/c Cancel editing of current record – no changes are saved

/q Skip remaining items – changes are saved

 Type a ?/ to show the list above on the screen. 

 All of these control options are not available on each screen within QWDATA. Available 

cursor controls are shown on the bottom of the screens within the program. 

 When the cursor is in the Method Code Field, the "/+" and "/-" options move the cursor to 

the next or previous block of result information, respectively. In other fields, these 

options move the cursor forward or backward the specified number of items." 

 The “/x” option moves the cursor to the specified item or field within an item. For 

example “/3” moves the cursor to parameter number 3; “/dqi” moves the cursor to the 

DQI field.
5.2 Tip Sheet: How do I manually login my sample and enter field data?

Water Quality 680 NWIS User

5.2 Tip Sheet: How do I manually login my sample and enter field data?

Note : The sampling site must exist in the NWIS Sitefile before 

samples can be logged in or water-quality data can be entered. The 

program for adding a new site to the NWIS database is described in 

Section 3.7.2--Add new site or modify site information. Access to this 

program may be restricted to more experienced database users.

 Choose option 1 from the main QWDATA menu. 

 Items required to login a sample are highlighted on the screen and include: agency code, 

station number, begin date, time datum, time datum reliability code, medium code, 

sample type, analysis status, hydrologic condition, and hydrologic event. The items are 

sometimes referred to as the sample header information and are described in Section 3.1. 

 If you are entering a tissue sample with a medium code of BA, BP, BAQ or BPQ, the 

organism and body part codes become mandatory fields.

 You can search the valid codes for most of the items on this screen by typing "?" in the 

first column after the item.

 After entering the sample header information, you are asked: Do you want to enter any 

data for this record (Y/N)?

 If you respond with an "N", a record number is generated. You may want to keep track 

of this record number on your field sheet or another location for future reference. 

 If you respond with a "Y", the following query appears: 

Are you entering lab (L) or field (F) data? (L or F, <CR>=F)? 

 If F is chosen, the program described in Section 3.2.1 is initiated and you are asked: 

Enter field form nn, ?nn for detail of form nn, ? for list of forms available. 

 If L is chosen, the program described in Section 3.2.2 is initiated and you are asked: 

Enter field form nn, ?nn for detail of form nn, ? for list of forms available. 

 The "nn" in the prompt refers to the field form number contained in the file name: 

field.parmsnn, stored in the directory /usr/local/nwis/data/auxdata/qw_field_forms/, where 

"nn" represents the 2-digit form number (e.g. field.parms01). 

o Information about adding and designing a field form is available in Section 2.10

and Tip Sheet 5.3. 

 If you choose to enter field data (short form) and enter a field form number, you can enter 

the data value, rounding precision, data-value remark, data quality indicator (DQI), nullvalue qualifier, value qualifiers, and result field comments for each of the parameters in 

the field form, which are described in Section 3.2.1. 

 If you choose to enter laboratory data (long form) and enter a field form number, in 

addition to the fields listed above, you can also enter information about the reporting 

level used, the preparatory set number and date; the analytical set number and date; and 

result field and result laboratory comments for each of the parameters in the field form, 

which are described in Section 3.2.2. 
5.2 Tip Sheet: How do I manually login my sample and enter field data?

Water Quality 681 NWIS User

 Cursor control characters and options shown at the bottom of the field-data entry screen 

are described in Section 2.2.2 and Tip Sheet 5.1, and can be displayed on the screen by 

typing "?/". 

 Additional parameters may be added during data entry without adding them to the field 

form by entering "/a" at any time. 

 After the data entry is complete, the user is given an opportunity to make changes or 

enter a carriage return to continue. This carriage return completes data entry and a record 

number is generated. You may want to keep track of this record number on your field 

sheet or another location for future reference.

 After the record is stored, you must answer the query: Login another record 

(Y/N,<CR>=Y)? An "N" ends the program and a "Y" allows the user to login another 

sample. 

 If a "Y" is entered, you must answer the query: Do you wish to edit the same header 

(Y/N,<CR>=Y)? The ability to edit the previous sample information allows for the rapid 

login of samples that contain similar information contained in the previous sample. 
5.3 Tip Sheet: How do I design a field form...and why would I want to?

Water Quality 682 NWIS User

5.3 Tip Sheet: How do I design a field form...and why would I want to?

 Field forms allow the user to design a data input file containing the parameters that are 

routinely entered for a particular project, field trip, a local office water-quality field sheet, 

or data from a non-USGS laboratory.

 Creation of new field forms should be completed if the available field forms do not 

contain one that can be used for the needed purpose. This requires that the available field 

forms be reviewed prior to creating a new one.

 A field form is a file containing a list of parameter codes, method codes, parameter 

names or descriptions, analyzing entity codes, and identification that a parameter is 

mandatory for that form. Field forms are used in the Enter Field Results, program

(Section 3.2.1), the Enter Laboratory Results program (Section 3.2.2) and in the Login 

Sample program (Section 3.1). 

 Any editor that produces an ASCII output file can be used to create or edit a field form 

file.

 Any numeric parameter can be entered into a field form. Alpha parameters (such as 

GUNIT for geologic unit code) cannot be used in the field form. 

 Up to 100 parameters can be included in a field form. 

 Attach to the directory: /usr/local/nwis/data/auxdata/qw_field_forms 

 List the directory to see what field form numbers already exist before selecting a new 2-

digit form number to create.

 Initiate the editor from this directory and enter the data in the format shown below. Save 

the file as field.parmsnn where ‘nn’ is the new 2-digit number. 

 The first line of the field form should be used to document the purpose of the field form 

by placing a "#" in the first column. Additional lines can be used for comments as long as 

a "#" is in the first column of the line. The format and an example of a field form are 

shown below. 

 Use caution when creating descriptions for parameters to ensure that they are clear and 

match the definition in the PCD for that parameter. For example, if the parameter is 

defined as ‘dissolved’ in the PCD, then the description in the field form should contain 

‘dissolved’ in the parameter description. 

 Be sure that the final line of the field form contains a carriage return at the end. If this is 

not included, the last parameter will not be included to enter data.

 The field form must be space delimited. If any other delimiter is used an error will result 

when using the field form for data entry. 
5.3 Tip Sheet: How do I design a field form...and why would I want to?

Water Quality 683 NWIS User

Format of Field Form

Line 1 Begins with a "#" in column 1 and is used to describe the purpose of the field form, 

name of the person who designed the form, and date created. (This line is not 

required but is strongly recommended because the line is displayed if a list of field 

forms is requested.)

Columns 1-5 Parameter code [5 digits, use leading zeros].

Column 6-10 Method code [optional] (5-character code)

Column 11 Not used.

Columns 12-36 Parameter names or descriptions [could match local office water-quality field 

sheet]

Column 40 Y indicates parameter is mandatory.

Column 42-49 Analyzing entity code (8-character code, See Appendix K for allowed entries)

5.5 Tip Sheet: How do I edit data that are already in the database?

Data that are already in the database can be edited in one of two ways. From the main QWDATA 

menu, choose option 2 – Modify samples or results or option 8 – Batch Processing. The Batch 

Processing option is recommended when large-scale or many small-scale changes to the database 

need to be made. The data are retrieved from the database in tab-delimited format. Changes are made 

to the batch files using the batch-file editor or an external text editor, and the corrected files are 

reprocessed using Batch Processing menu options 1, 2, 3, or 4. This process is described in more 

detail in Tip Sheet 5.9. 

This tip sheet describes the basic steps required to edit data that already exist in the database using 

QWDATA main menu option 2. 

 The user must know the record number of the sample that is to be edited or the agency code, 

site number, begin date, begin time, end date (if there is one), end time (if there is one) and 

medium code before proceeding. Note: You must have write-access to the database.

 Choose option 2 – Modify samples or results from the main QWDATA menu. 

 Choose option 3 – Edit samples or results from the Modify samples or results menu, and the 

following “qwedit” screen is displayed. Note: Before proceeding, confirm that the user is in 

the correct database.

5.6 Tip Sheet: How do I table data in publication-style table format?

Water Quality 689 NWIS User

Note: A user with read-only access to the database will be able to table results with data 

quality indicator (DQI) codes of A – historical, S – presumed satisfactory, or R – reviewed and 

accepted. A user must have write access to table results for DQI codes of Q – reviewed and 

rejected, I – awaiting review, U – unapproved method or lab., or P, O, or X – proprietary 

results.

 After the table is retrieved, you can create another table with the by-sample format by 

entering a ‘Y’ at the next prompt and the tabling program will begin again. If another table is 

not required, type ‘N’ at the prompt. 

 The output file contains “Fortran carriage control” characters. Use the Unix command: 

asa <filename> | lp –y landscape –d<printer name>

to print the formatted file. Fortran carriage-control characters are numeric codes written in 

the first column of each line describing how the printout should appear. If the command ‘–

d<printer name>’ is not appended, the destination will be your default printer. For more 

details, see manual page (“man lp”).

Water Quality 690 NWIS User

5.7 Tip Sheet: How do I make flat files to use data in programs outside of QWDATA?

This tip sheet describes the basic steps required to make a flat file using column-style (by-sample) 

output. If you would like to make a flat file using row-style (by-result) output, refer to Section 3.4.6. 

Flat files do not include titles or column headings, but are simple columns of data. This type of 

output is typically used for simple data reviews or to enter data into other software. Links to sections 

in the documentation that contain details for certain topics are included in this tip sheet. The user 

should refer to those sections for details that are not presented in this tip sheet. 

 You must have a file of record numbers before beginning the tabling program. Create this file 

if you do not already have it. See Section 3.3.1 or Tip Sheet 5.15 for more information about 

retrieving records.

 Choose option 4 – Data Output from the main QWDATA menu.

 Choose option 5 – Flat File by Sample from the Data Output menu. 

 Six options are available to create a flat file using by-sample output: 

qwtable -- Flat file (by sample)

You have 6 options for flatfile output:

 1 -- Fixed column flat file (qwflatout)

 2 -- Flat file with TAB delimiter (RDB format)

 3 -- Flat file with user-specified delimiter

(Following options include method code in output)

 4 -- Fixed column flat file (qwflatoutm)

 5 -- Flat file with TAB delimiter (RDB format)

 6 -- Flat file with user-specified delimiter

Enter option desired (1-6, <CR>=1):

 Option 1 produces two files: one with the data in fixed columns separated by spaces and 

the other containing a list of parameter names. This option can be used to import the data 

to other programs; however, delimited files are better for some programs (see option 3). 

 Option 2 produces a tab-delimited RDB file with header lines at the top of the file 

containing parameter and format information followed by the data. Only those users 

wishing to use the RDB capabilities should choose this option.

 Option 3 produces two files: one with the data delimited by the user-defined delimiter 

and the other containing a list of parameter names. This option can be used to import the 

data to other programs. 

 Options 4-6 are similar to options 1-3, but the output also includes method codes when 

method codes exist with a result. This option creates an extra spaces or column for each 

parameter specified in the parameter list to hold a method code; in some cases this 

column may be blank because no method code exists. 

* See Section 3.4.5 for more details about these options.* 

 Each option has the following prompts: 

 Options 1 and 4: 

Enter name of file containing record numbers (Q to quit):

Enter name of file to hold output – 

 Options 2 and 5: 

Do you want remarks and values to be delimited (Y/N,<CR>=Y)? 

Enter name of file containing record numbers (Q to quit):

Enter name of file to hold output – 

 Options 3 and 6: 

Enter column separator char or TAB for tab char:

Do you want remarks and values to be delimited (Y/N,<CR>=Y)? 

Enter name of file containing record numbers (Q to quit):

Enter name of file to hold output – 

 Options 2, 3, 5, or 6 allow you to separate remarks, such as < or E, into a different 

column from the values by answering ‘Y’ to that prompt. For options 3 and 6, any 

character may be used as a column separator, but the most common are tabs, commas, 

and slashes.

 Provide parameter codes to be tabled. This may be done interactively or by providing a file 

name for a file containing the parameter codes. See Section 3.4.3.3 for more information 

about providing parameter codes and Appendix G for the format of a parameter code file.

 Choose table output options from the screen ‘qwtable -- current selections for options’. See 

Section 3.4.3.4 for detailed information on table output options. Following is the table 

options screen, X’s indicate the default settings:

5.9 Tip Sheet: How do I load data using batch processing?

Water Quality 695 NWIS User

5.9 Tip Sheet: How do I load data using batch processing?

 Batch processing is used for loading electronic data files, generally from laboratories and 

including non-USGS laboratories, into the database.

 Files typically named qwsample and qwresult are used by QWDATA to load data via batch 

processing.

 Descriptions of the batch file formats are in Appendix F. A document that describes the 

requirements for external laboratories that may want to produce the batch format is located at 

(Internal USGS users only) http://phoenix.cr.usgs.gov/www/lab_coord.html.

 To begin batch processing, choose option 8 – Batch Processing from the main menu. See 

Section 3.8 for more details about this option. 

 The Water-Quality Data Transfer System (QWDX) is used by the NWQL and other USGS 

laboratories to transmit data to their customers. You should first retrieve the qwsample and 

qwresult batch files from the QWDX system. The retrieval can be done using an automated 

or manual process. 

 The program will look for the qwsample and qwresult batch files in the directory where the 

program is initiated.

 The batch process can be run in one of three ways: 

1. The batch process updates sample records that are already in the database (option 1 – 

Enter batch-file data for logged-in samples). The data are matched based on agency code, 

site ID, begin date and time, end date and time, and medium code which are contained in 

the sample-level file (qwsample). The result-level data (qwresult) are appended to the 

existing sample.

2. The batch process enters and updates samples in the database (option 2 – Enter batch-file 

data for all samples). The data are matched based on agency code, site ID, begin date and 

time, end date and time, and medium code, which are contained in the sample-level file 

(qwsample). If a match is found, the result-level data (qwresult) are appended to the 

existing sample. If a match is not found, a new sample is created and the result-level data 

are processed.

3. The batch process provides an interactive, screen-oriented, batch-precursor program for 

the expert user to set batch modes (option 4 – Enter batch-file data with user-specified 

behavior). The filename, the transactions allowed, whether or not the results are protected 

by DQI codes, the type of data that can be updated (lab only or lab + field), and whether 

or not an ionic balance is prepared are behavior modes that can be selected by the user.

Four types of transactions are allowed: 

• Only updates to samples. This is the same mode as when the Batch Processing, option 

1, Enter batch-file data for logged-in samples option is selected. 

• Only addition of new samples. This is the mode used for the addition of new samples 

to the database. This option cannot be used for updating existing samples. 
5.9 Tip Sheet: How do I load data using batch processing?

Water Quality 696 NWIS User

• Any transaction. This is the same mode as when the Batch Processing, option 2, Ente

batch-file data for all samples option is selected. 

• Verification only, no transactions stored. This capability provides for a “dry run” of 

the batch program. This mode can be useful for checking data from an external sourc

or for cleaning up data prior to an attempt at storage in the database. The sample 

record number is reported as “Unstored” on the WATLIST when this mode is used. 

Rejected sample and result files are created in verification mode, but these files 

contain only those records that would have been rejected if the user had attempted to 

store the data. 

 Environmental and quality-control (QC) data are directed to an appropriate database based o

the sample medium code. Appendix A describes medium codes and identifies which are 

environmental or QC media. Each user is linked with a pair of environmental and QC 

database numbers. The linkage can be changed using option 7 – Utilities from the main 

menu, submenu option 1 – Change Database Number. If no linkage has been established for

the userid, then databases 01 and 02 are used for the environmental and QC samples. 

 A record of the actions taken when a batch file is processed is written to a file named 

watlist.yyyymmdd.hhmmss. The first page of this file identifies the options used during the 

batch processing and the file names processed. The subsequent pages present each of the 

samples processed, sorted by project number. 



r 

e 

n 

Each result row printed in the watlist is preceded by a one-letter transaction code. 

Transaction

code Explanation

N New stored result from the batch

U Updated result from the batch

P Previously stored result prior to the batch

D Deleted result stored prior to the batch

X Present in the batch, but ignored due to errors

C Calculated, not stored

‘blank' Previously stored and unchanged by the batch

 The watlist also contain a cation/anion balance and messages from validation checks. The 

watlist should be reviewed for chemical accuracy and preserved for the required length of 

time per Federal Records Disposition Schedule as part of the official record for the sample, 

as it is considered original data. 

 Data for samples that are not successfully processed with the batch program are output to 

files for clean up (rejected.sample.yyyymmdd.hhmmss and 

rejected.result.yyyymmdd.hhmmss). 

 Samples that are not successfully processed have one or more of the following problems: 

(a) invalid formats (columns have been shifted, etc), 

(b) invalid site IDs, dates, times, or medium codes, 

(c) results for samples that do not already exist in the water-quality file (except for menu 

options 2 and 4), 
5.9 Tip Sheet: How do I load data using batch processing?

Water Quality 697 NWIS User

(d) samples that contain results that are overwrite-protected with a DQI value (except menu 

options 3 and 4), and

(e) an incorrect transaction type is selected from menu option 4.

 There is a batch-file editor available through the batch menu, option 6 – Edit tab-delimited 

batch files, for fixing errors in files that are in the tab-delimited format. A text editor can also 

be used to edit the tab-delimited files, but the user should be extremely careful not to delete 

or add tabs used to separate the columns of data. 

 To help verify the format of tab-delimited files, the program qwcat can be used. For more 

information about this program refer to Section 3.9.

 After the necessary steps are taken to correct any problems, the corrected samples can be 

entered by renaming the files to the appropriate batch filename (qwsample and qwresult) and 

initiating one of the batch input programs (options 1, or 2). If option 4 is selected, the files do 

not need to be renamed. 

 If data are rejected during the batch loading because of DQI protection but you have 

reviewed the new data and accepted it, you can reload the data from the batch file and 

override the DQI protection using option 3 – Reload batch-file data, overriding DQI, 

assuming you are certain that you should overwrite the previously reviewed results. 
5.10 Tip Sheet: How can I use SQL to retrieve data from the database?

Water Quality 698 NWIS User

5.10 Tip Sheet: How can I use SQL to retrieve data from the database?

 The Structured Query Language (SQL) provides a method for retrieving data from a relational 

database, such as NWIS.

 There are several different ways to query a database using SQL. This tip sheet focuses on the 

UNIX “tsql” command. Other mechanisms include packages such as MS-Access and ESRIArcInfo. Using “sqlplus” is another example. Each mechanism employs a different user 

interface and may have a somewhat different syntax.

 A valid “tsql” command consists of several phrases. 

tsql database_name [options] “SQL_statment” 

tsql Every tsql statement begins with this phrase.

database_name Usually the characters “nwis” followed by a two-character state 

suffix. The name of the NWIS database on the local computer can 

be displayed with the UNIX command cat /usr/opt/nwis/.nwisdb. 

[options] Optional arguments to control the behavior of “tsql.” 

The most commonly used option is “-rdb” to produce a RDB 

output. Use “man tsql” for other options.

“SQL_statment” An SQL query enclosed in double-quotation marks.

 The output of a “tsql” query is often redirected to a file, or piped to another command for 

subsequent processing, using the UNIX-shell operators “>” or “|”. 

 Composition of the SQL statement consists of three main specifications:

1. A list of the columns to output, 

2. The name of the database table(s) containing those columns, and 

3. An optional restriction clause that limits which rows of data are retrieved.

 The syntax for stating these specifications looks like:

”select column-list from table-name(s) where restriction-clause”

 The column and the database table names can be determined from inspection of the database 

design documents. 

 Here is an example query that retrieves a list of record numbers and parameter codes from 

database 01 where the ‘V’ remark code has been stored:

tsql nwishq “select record_no, parm_cd from QW_RESULT_01 where remark_cd = ‘V’” 

Note the two-column names are separated with a comma, the literal V-remark code is within 

single-quotation marks, and the entire SQL statement is surrounded by double-quotation marks. 

To save the results of this query into a file named “my_v_samples.txt”, append the following to 

the command: “>my_v_samples.txt”.
5.10 Tip Sheet: How can I use SQL to retrieve data from the database?

Water Quality 699 NWIS User

 This query employs the SQL keyword “distinct” to limit the output to unique record numbers 

where any results have a DQI code of ‘A’. Thus, duplicated record numbers are omitted for 

those samples where more than one result satisfies the query.

”select distinct record_no from QW_RESULT_01 where dqi_cd = ‘A’”

 More than one table can be queried in the same SQL statement. When querying more than one 

table, each column name is annotated with a shorthand reference to the corresponding table, and 

you must identify (in the where clause) how the tables are linked or joined. Identically named 

columns in the two tables usually are linked. See below how the column record_no is joined 

from each table. For example:

”select a.agency_cd, a.site_no, a.hyd_cond_cd, b.remark_cd, b.result_va, parm_cd from QW_SAMPLE_01 a, 

QW_RESULT_01 b where a.hyd_cond_cd in (‘5’,‘6’,’7’,’8’) and a.record_no = b.record_no and b.parm_cd = 

‘00061’”

The two tables have been assigned the arbitrary shorthand names of “a” and “b” in the “from” 

clause, and this shorthand has been used as column-name prefixes in the column-name list, as 

well as the “where” clause. The shorthand prefix “a” identifies columns in the table 

QW_SAMPLE_01 and the shorthand prefix “b” identifies columns in the table 

QW_RESULT_01. 

The linkage between the two tables is specified by the phrase: “and a.record_no = b.record_no”. 

An omitted or incorrect linkage phrase typically causes voluminously useless results and very 

slow query response time. 

This example investigates stations and instantaneous discharges (parameter code 00061) where 

the hydrologic condition is “falling stage”, “stable high stage”, “peak stage”, or “rising stage”. 

 The “where” clause may contain column names, comparison operators, literals, and logical 

operators. Previous examples have demonstrated some of the syntax. Literal text variables are 

quoted; literal numeric variables are not quoted. The table below presents some additional 

operators that can be used in a “where” clause. 

Operator Type of

!= comparison not equal to

>= comparison greater than or equal to

(comparison differs for numeric or text 

variables) 

<= comparison less than or equal to

> comparison greater than

parenthesis.

or logical either are true

Here is an example query using some of the above operators. 

”select a.record_no, b.parm_cd from QW_SAMPLE_01 a, QW_RESULT_01 b, QW_SAMPLE_CM_01 c where 

b.null_val_qual_cd is not null and a.record_no = b.record_no and c.sample_cm_tx like ‘%meter%’ and b.record-

_no = c.record_no”

This example retrieves the record number and parameter code for each result with a non-null nullvalue qualifier code and either field or laboratory sample comment contains the text “meter”.

 Date and time variables (column names ending in “_dt”) in the NWIS water-quality subsystem 

are stored within the database in Universal Coordinated Time (UTC). When retrieved using tsql, 

the time zone will be UTC. The time-datum information coded with the sample record is not 

used during this conversion. Therefore, to obtain date-time information as entered into the 

database, use SQL to select the record numbers, and then retrieve the date-time information 

using the database software rather than using SQL.

 Blank strings versus NULL/empty strings: Null is not equal to a blank string in Oracle. If 

searching with column='', Oracle will treat this as a null entry. If you have a clause that contains 

search criteria looking for blank strings, it will need to be written as column=' '.

 The information contained in this Tip Sheet is not a comprehensive SQL reference. Other 

references should be consulted for additional information. 
5.11 Tip Sheet: How should sample type be coded for environmental and quality-control samples?

Water Quality 701 NWIS User

5.11 Tip Sheet: How should sample type be coded for environmental and

quality-control samples?

Sample Type is a required field to be stored with all samples. This tip sheet includes the 

recommended coding of sample type for environmental and quality-control (QC) samples. In 

addition, guidance is provided for storing selected parameter codes that are associated with 

certain sample types, which further describe QC samples. For complete descriptions of sample 

types, see Appendix A, table 4; however, some of these codes are now considered obsolete. 

 The recommended sample type codes to use for your samples are shown in the following 

table. Although other codes exist in the QWDATA software and historical data, the codes 

shown in the table are the preferred sample types to use for storing new samples. 

Sample type codes

Code Description

9 Regular (discrete), environmental sample.

H Composite (through time), environmental sample. 

7 Replicate, environmental sample and the associated replicate 

quality-control sample(s). 

2 Blank, quality-control sample. 

1 Spike, quality-control sample. 

3 Reference, quality-control sample.

B Other, quality-control sample. 

 For environmental samples that do not have an associated replicate QC sample, the 

coding is limited to two codes—9 (regular) and H (composite). For routine discrete 

samples, set sample type to 9 (regular). For samples that are composited through time and 

have both a begin date/time and an end date/time, set sample type to H (composite). 

 For environmental samples that have associated replicate QC sample(s), code the 

environmental sample and QC sample(s) with sample type 7 (replicate). Storing sample 

type as 7 will help the user find replicate samples in both the environmental and QC 

database during retrieval. 
5.11 Tip Sheet: How should sample type be coded for environmental and quality-control samples?

Water Quality 702 NWIS User

 For the replicate sample type (7), fixed-value parameter 99105 (type of replicate) should 

be stored with the QC sample only to further describe that sample. For example, set 

99105=10 if the replicate sample was collected with a concurrent sample collection 

procedure. (See Appendix B for all possible codes for any fixed-value parameter.)

 For blank sample types (sample type=2), the following fixed-value parameters should 

also be stored. 

99100 Type of blank solution (for example, 40=organic-free water)

99101 Source of blank solution (for example, 10=NWQL) 

99102 Type of blank sample (for example, 100=field blank) 

In addition to storing fixed values, ancillary information about primary blank water lot 

numbers can be numerically stored with the following parameter codes. 

99200 Lot number, first, inorganic-grade water

99202 Lot number, first, organic-grade water

99204 Lot number, first, VOC-free water

Parameter codes 99201, 99203, and 99205 also can be used to store lot numbers. 

 For spike sample types (sample type=1), the following fixed-value parameters should 

also be stored. 

99106 Type of spike (for example, 10=field spike) 

99107 Spike source (for example, 10=NWQL) 

In addition to storing fixed values, other spike sample ancillary information can be 

numerically stored with the following parameter codes. 

99108 Spike volume, milliliters (or use 91132 Spike volume, microliters) 

99104 Reference material or spike lot number 

Parameter codes 99150, 99151, 99152, 99153, and 99154 also can be used to store lot 

numbers. 

Spike samples also need a result storing the sample volume appropriate for the spiked 

analytes of interest. The NWQL will normally provide a schedule-specific parameter, 

such as 99856; otherwise use 32002: Sample volume, milliliters. 

 For reference sample types (sample type=3), the following fixed-value parameter should 

also be stored. 

99103 Source of reference material (for example, 100=chemical supplier) 

In addition to storing the fixed value, ancillary information for the reference material 

primary lot number can be numerically stored with the following parameter code. 

99104 Reference material or spike lot number 

Parameter codes 99150, 99151, 99152, 99153, and 99154 also can be used to store lot 

numbers. 
5.11 Tip Sheet: How should sample type be coded for environmental and quality-control samples?

Water Quality 703 NWIS User

 Quality-control samples are often used to isolate the source of a previously identified 

problem or to determine if a change in data collection and processing has an effect on the 

results. These samples are “topical” QC samples and should be coded with sample type B 

and further described with explanatory sample comments. 

In addition, the following fixed-value parameter can be stored.

99112 Purpose of topical quality-control data (for example, 100=topical QC for 

variability due to field equipment)

 Users can develop field forms (5.3 Tip Sheet) to use with QC samples to help insure 

consistent coding of these types of samples. 
5.12 Tip Sheet: Why is there an “M” in my data?

Water Quality 704 NWIS User

5.12 Tip Sheet: Why is there an “M” in my data?

The “M” is one of three possible remark codes that are associated with nonquantitative 

measurement results.

Remark

code Explanation Detectionstatus

M Presence of material verified but not quantified Detected.

N Presumptive evidence of presence of material Detected.

U Material specifically analyzed for but not detected Not detected.

An “M” remark code may be printed in output for various reasons, as explained below. 

Some procedures are inherently nonquantitative, such as the “sniff test” for hydrogen sulfide. 

Results for nonquantitative methods are stored in the database using the above remark codes 

without corresponding values. Sometimes, however, a quantitative method produces a numeric 

result below the range of reliable precision; this causes the value to round to zero. A zero is 

misleading because it implies that the material is known to be absent (not detected). The NWIS 

software replaces most values that round to zero with an “M” remark code. (Some parameters 

such as temperature are allowed to round to zero.) 

You can determine whether the data are rounding to zero and being replaced with “M” by 

retrieving the unrounded data (see Tip sheet 5.19) and parameter code, remark, value, and 

method. If no quantitative results are presented when data are retrieved unrounded, then the “M” 

remark was stored. 

Alternatively, results that are rounded to zero and replaced with an “M” remark code indicate 

that the quantified result is outside the reliable range and has no reportable digits. The rounding 

algorithm typically depends on the precision specifications that are associated with each 

analytical method; therefore, verify that the analytical method is stored and that the method code 

is correct. You can look up method and precision information by using the option described in 

Section 3.6.8 – Display the Parameter Method Table. 

The precision specifications associated with a blank (unknown) method typically are crude and 

represent the reproduction of less modern methods. Storage of an appropriate method code may 

allow the result to round to a non-zero value. Similarly, storage of an inappropriate method code 

may also cause the rounding to be incorrect. In some cases, the method code stored with the 

result may be correct, but the rounding specification stored in NWIS may be incorrect. In these 

instances, you should work with the laboratory to determine if the rounding specification needs 

to be updated. If so, contact the Office of Water Quality to request that the method precision data 

be altered.

Some laboratories, including the National Water Quality Laboratory (NWQL), present raw 

results in their transmission to customers. Groups of raw results can be useful in statistical 

summaries and graphs, especially when analyzing quality-control samples; however, individual 

raw results should never be presented in USGS reports. Note that the NWQL’s sample-status 

Web page presents raw laboratory results.
5.13 Tip Sheet: How do I make large-scale updates to data?

Water Quality 705 NWIS User

5.13 Tip Sheet: How do I make large-scale updates to data?

There are several different ways of making large-scale updates to the database, including batch 

processing, UNIX scripts, and Standard Query Language (SQL). Recommendations on which 

technique to use and when to use that technique are described in this tip sheet. 

Batch Processing:

Batch processing can be used to change sample-level information or to add, change, or delete 

results for existing sample records. 

 The NWIS software accepts “tab-delimited” formatted files. These files are typically 

called qwsample and qwresult. Description of the batch file format is in Appendix F.

Users are referred to Tip Sheet 5.9 or Section 3.8 for more details on batch processing. 

 To create a batch file which can be used for making updates, option 7 – Produce tabdelimited batch files can be used from the Batch Processing menu. 

 Large-scale updates should be made using option 4 from the batch processing menu so 

that any attribute in the tab-delimited formatted can be updated. See below for details.

 A remark code of ‘X’ will delete a result and all of the associated attributes.

 A geologic-unit code of “DELETE” will delete a sample and all associated result records. 

 The batch process to use for updating laboratory data that are already in the database is 

option 1 – Enter batch-file data for logged-in samples (qwcardsin). 

 The batch process to use for entering new samples or updating laboratory data is option 2 

– Enter batch-file data for all samples (qwenter). 

 The batch process to use for updating laboratory data that have DQI protection is option 3 

– Reload QW data from batch file, overriding DQI (qwcardsinxdqi). 

 Option 4 – Enter batch-file data with user-specified behavior (user-specified modes)

allows the user to customize the batch processes by selecting: 

1. to enter a specific batch file name, 

2. one of four types of transactions (only updates to samples, only additions of new 

samples, any transaction, or verification only—no transactions stored), 

3. to over-ride update protection of reviewed results (DQI protection), 

4. to update only lab, or lab and field data, 

5. to print an ionic balance, 

6. to enable user-specified alert limits. 

 A record of the actions completed during any batch process is written to a file named 

watlist.yymmdd.hhmmss for options 1, 2, and option 4. 
5.13 Tip Sheet: How do I make large-scale updates to data?

Water Quality 706 NWIS User

 The parameter codes listed in the watlist are preceded by a one-letter code to indicate the 

type of transaction. 

o N New stored result from the batch

o U Updated result from the batch 

o P Previously stored result prior to the batch 

o D Deleted result stored prior to the batch 

o X Present in the batch, but ignored due to errors 

o C Calculated, not stored 

o ‘blank' Previously stored and unchanged by the batch 

UNIX Scripts:

UNIX scripts generally are used to capture queries that are frequently repeated. 

 UNIX scripts require the responses to database prompts to be exactly what was planned 

for in the UNIX script. If an unexpected database prompt is encountered while a UNIX 

script is processing, the script will provide responses to database prompts that are 

incorrect and data could potentially be corrupted. 

 UNIX scripts should only be used by experienced UNIX users and in situations where 

there is no potential for planned database prompts to deviate from actual database 

prompts. 

SQL: 

SQL may be used for data retrievals by trained database personnel, but it is not recommended 

for any data updates. Reasons for this include: (1) date-time information are internally stored 

in UTC; (2) certain attributes have domain-list enforcement; (3) relational tables are linked 

with identifiers that could be corrupted and referential integrity broken; and (4) logical rules 

among inter-related fields (such as rpt_lev_va & rpt_lev_tp). See Tip Sheet 5.10.

 If a situation arises where you need to change a large data set and batch processing or 

UNIX scripts will not work, please contact the NWIS office for assistance in evaluating 

whether SQL can be used to change data for your particular data scenario. If SQL is 

determined to be the only viable approach, NWIS staff would assist in developing an 

SQL script to update the data. 
5.14 Tip Sheet: How do I use null values?

Water Quality 707 NWIS User

5.14 Tip Sheet: How do I use null values?

There are two situations where a null value is appropriate. The first situation is a null value that 

is the result of non-quantitative test indicating only the presence or absence of a constituent. The 

second situation is when an attempted measurement is not successfully completed due to 

logistical problems or unintentional errors, and a null value is stored in the data documenting the 

measurement attempt and the reason that no numerical result was stored. In general, most null 

values will be from laboratory analyses; however, null values can also be entered for field 

values.

There are two ways that a null value can be entered into QWDATA

 Interactive

• Details about how to enter data interactively in QWDATA is available in Section 3.2.

• A null value is entered in the database interactively by entering a ‘#’ character in the value

 field in the field form, the laboratory-data entry form, or while editing existing data. 

• After the ‘#’ is entered, the user is required to qualify the null value with either a “null 

value remark” or a “null value qualifier”, as described by the screen prompts:

You have specified a NULL result value. You must qualify null 

values with a null value remark code or a null value qualifier code.

Null Value Remarks: Null Value Qualifiers:

M:Presence verified but not quantified a:Planned measurement was not made

N:Presumptive evidence of presence. b:Sample broken/spilled in shipment

U:Analyzed for but not detected. c:Sample lost in lab

 e:Required equipment not functional/avail 

 f:Sample discarded: improper filter

 i:Required sample type not received

 l:Analysis discarded: lab QC failure

m:Results sent by separate memo

 n: Non-performing compound, reasons unknown 

 o:Insufficient amount of water 

p:Sample discarded: improper preservation

 q:Sample discarded: holding time exceeded

 r:Sample ruined in preparation 

 u:Unable to determine-matrix interference

 w:Sample discarded: warm when received

 x:Result failed quality assurance review

Enter a remark code (R) or a qualifier code (Q)? 
5.14 Tip Sheet: How do I use null values?

Water Quality 708 NWIS User

• After entering ‘R’ or ‘Q’, choose the remark or qualifier for the null result.

 Batch

• A null value can be entered in using batch files if the value is blank and a valid nullqualifier or remark code is present for the result record in the tab-delimited “qwresult” file 

Batch processing is discussed in Section 3.8. 
5.15 Tip Sheet: How do I retrieve records for use in other QWDATA programs?

Water Quality 709 NWIS User

5.15 Tip Sheet: How do I retrieve records for use in other QWDATA programs?

Programs used to view data in the QW database (data review, data output, and graphics 

programs) either require or will accept a file of record numbers. Additional information 

about record numbers can be found in Section 2.1.5. This tip sheet describes how to create a 

file of record numbers from a single database. Site or record retrieval from multiple 

databases can be done using similar steps; the user is prompted for the information for each 

database specified. Section 3.3.2 provides details about retrieving data from multiple 

databases.

 Selecting sites or samples from a single database may be accomplished from two options 

in the QWDATA main menu: option 3 – Data Review or option 4 – Data Output. From 

either of those menus, choose option 1 – Select Sites or Samples. 

 Three options are available for retrieving water-quality records from specific sites and 

one option is for retrieving water-quality information for any sites. See Section 3.3.1.1 for 

detailed information.

qwsiterec -- locate record numbers for use by QW application programs

QW database(s): 01 

You may locate records for specific sites.

If you wish to locate records for specific sites the options are:

 1 -- You have a file containing site numbers

 2 -- You will enter site numbers at terminal

 3 -- You wish to locate sites based upon selection criteria

If you don't care which sites the option is:

 4 -- Locate QW records without regard to site

Please enter option (1-4,Q to quit): 

 If sites are retrieved, the option is given to sort the sites after retrieval. The retrieved sites 

may be sorted on a variety of fields that will be displayed by the program.

 If the retrieved sites will be used in the future, save them to a file.

 Regardless of the option chosen, you will be given the opportunity to refine the waterquality records retrieved using the following menu: 
5.15 Tip Sheet: How do I retrieve records for use in other QWDATA programs?

(4) PROJECT ID: _ (5) GEOLOGIC UNIT: _ (6) PARAMETER VALUES AND CODES: _ 

(7) PARAMETER GROUPS: _ (8) DATA QUALITY INDICATOR CODES: _ 

 See Section 3.3.1.2 for detailed information about the menu shown above. 

 Select “ANALYSIS-LEVEL CODES” to retrieve proprietary and (or) internal-use data. 

See Section 2.14 for definitions. 

 You will be given another opportunity to save sites that contain the requested waterquality information to a file. This group of sites may be a subset of the sites retrieved 

using option 1 or 2 in the first menu shown above. 

 The records retrieved can be sorted on a variety of fields (See Section 3.3.1.2 for more 

detailed information):

qwsiterec -- Total number QW records located: 12227

Do you wish to sort the located QW records (Y/N)? Y

You may sort on any combination of the following fields: 

 A -- Agency code F -- Geologic unit code 

 B -- Station number G -- County code 

 C -- Dates and times H -- Station name 

 D -- Medium code I -- Station type 

 E -- Project ID 

The first field will be the primary sort

the next will be the secondary sort 1, ...

Please enter the sort codes on one line with no embedded spaces

Enter sort code(s): 

 Provide a file name for the file to hold the water-quality records. 

 The resulting file of record numbers can be used in QWDATA programs that accept files 

of record numbers. Use clear, descriptive filenames if these record numbers will be used 

again.

Notice that the “PR Creator’s email ID” field will be automatically populated with your user ID.

 If there are others that might want to know about the progress of a solution to your 

problem, put their email IDs in the “Notify-List” box, separated by spaces. When 

information is added to the problem report, the PR Creator and those on the Notify-List 

will receive an email containing that information so that you know work is being 

completed on your problem.

 Choose the radio button for the “Category Type” that best represents where your problem 

occurred. The radio button chosen will limit the list of options in the category window. 

Click on the specific category from the window. If you know the name of the category, 

type it in the box, prefix first. 

 The “Synopsis” should include enough of a description that someone would be able to 

determine the situation that caused the problem or created the question or enhancement. 

Consider using 10 words or less. 

 Indicate the “Severity” by selecting from the drop-down list. Consider the extent to which 

your problem is hampering your work. A critical problem is one in which the programs 

stop working completely or data are incorrectly stored or displayed. A serious problem is 

one in which your workflow is seriously hampered. A non-critical problem is a question, 

an enhancement, or a problem that is annoying, but doesn’t significantly affect your 

workflow. 
5.16 Tip Sheet: How do I enter reports into the problem-reporting system?

Water Quality 715 NWIS User

 Indicate the “Class” of the problem by selecting from the drop-down list: 

• Software-bug – Problem requiring a correction to software 

• Software-enhancement – Suggested change in functionality 

• Support – Support problem or question 

• Documentation – Correction or improvement in documentation 

• Reference-list – Request for a change to a reference list

• Duplicate – Duplicate of another existing PR 

• Mistaken – Accidental PR submission 

When you enter a new report you will likely use one of the first five choices. 

 To determine the entries for release and environment, type nwisenv at your UNIX 

prompt. The release information is near the top of the resultant list in the form and will 

appear similar to: nwis-5.0.1-4. Choose the appropriate release from the “Release” pull 

down menu. Copy everything after User Environment: into the “Environment” text box.

 In the “Description” text box, enter a detailed description of your problem. This is your 

space to provide details to help NWIS personnel understand your problem. Please include 

results that illustrate the problem or how the problem is hampering your work. NWIS 

personnel will use this information to determine the severity of the problem as well as 

possible short-term and long-term solutions.

 If you have attachments that help illustrate the problem or provide information necessary 

to reproduce and troubleshoot the problem, provide the pathname in the “File 

Attachments” box. As an alternative, use the browse button to find the attachment on 

your machine, select it, and click open to place the pathname in the “File Attachments” 

box. Note: The GNATS web interface will only allow the addition of one attachment at a 

time. If you have multiple attachments to associate with a particular problem report, you 

will have to edit the PR each time you want to add another attachment. 

 The “Project Name” text box is generally reserved for NWIS and User Group’s use. This 

field allows PR’s to be associated together to provide a quick way of determining 

problems associated with a specific project release. There are projects that may cross 

multiple Categories, and usage of a consistent text-string will allow for grouping and 

retrieval of problem reports.

 In the “How to Repeat” text box, enter a step-by-step description you used to cause the 

problem to occur. You should include a list of the menu options used and a description of 

the files you used, if applicable. This set of instructions is critical for NWIS personnel to 

duplicate the problem on a test system.

 The “Fix” box will be completed by NWIS personnel or others when a fix or workaround 

information is available to resolve the issue. 

 As a last step, click on the Submit button at the top or bottom of the page. You should get 

a message back that you will receive an email containing the problem report number and 

some information that you entered. You should also be returned to your previous page 

quickly, but if needed, click on your web browser “Back” button.

5.17 Tip Sheet: How do I make linear plots of my data?

Water Quality 718 NWIS User

5.17 Tip Sheet: How do I make linear plots of my data?

This tip sheet describes the basic steps to make X,Y (linear) plots of data using a program 

available within QWDATA. If you would like to retrieve data from QWDATA and use a 

graphics program available outside of QWDATA, please refer to Tip Sheet 5.7. Links to sections 

in the documentation that contain details for certain topics are included. The user should refer to 

those sections for details that are not presented in this tip sheet. 

 All graphics programs within QWDATA are available from option 5 – ‘Applications’ in 

the main QWDATA menu. Details for all the options in this menu are available in 

Section 3.5 of the documentation. That option will display the following menu:

 QW DATA PROCESSING ROUTINE REV NWIS-5.0

 YOU ARE USING WATER-QUALITY DATABASE NUMBER 01

 Applications

 1 -- X,Y Plot

 2 -- Boxplots

 3 -- Stiff Diagrams

 4 -- Piper Diagrams

 5 -- Regression Plots

 6 -- Summary Statistics Table

 7 -- Detection Limits Table

 8 -- Discharge Report for QW Samples

 98 -- Exit menu

 99 -- Exit system

Please enter a number from the above list or a Unix command:

 Option 1 from the applications menu creates an X,Y plot in three stages: (1) retrieves 

data from the QW database that are written to an ASCII file, (2) uses data in the ASCII 

file to create the plot in a separate graphics (TKG2) window, and (3) from the TKG2 

window, the plot can be printed or saved to a file. 

o The first query is a check of your Unix DISPLAY environment variable to check 

that it is set correctly. If you need help with this step, please contact you local 

system administrator. You are given the opportunity to stop the program at this 

point. 

o The next query is asking for a file of record numbers to identify what samples will 

be included in the plot. All graphical programs require an input file of record 

numbers to operate. The format of this file is one record number per line in 

columns 1-8 and can be generated through QWDATA (see Section 3.3.1) or 

created with an editor. Examples of this input file are shown in Appendix G.

o The next query asks for the name of the ASCII data output file. The program 

produces an output ASCII file that contains the data used in the plot; the file will 

be saved to the directory where you started QWDATA. 
5.17 Tip Sheet: How do I make linear plots of my data?

Water Quality 719 NWIS User

o The next query will give you the choice of the type of X,Y plot that will be 

produced. Three options exist for plotting the data: (1) 1-7 parameters by one 

parameter, (2) 1-7 parameters by sample date, and (3) Multiple stations by sample 

date for one parameter. All three options will handle data from multiple stations; 

however, only option (3) will identify the individual stations on the plot.

o Which type of plot you choose determines the next set of queries, but most 

queries are related to what parameters you want to include in the plot. Enter the 

parameter codes that you wish to include on the plot. 

o After the program retrieves the data, a short set of summary information for the 

data retrieved is displayed to the screen for your review. 

o The next prompt, List the Data?, allows you to display all the data to the screen. If 

you choose ‘Y’ then the data are displayed in a paired format. For example if 

option 1 was selected and parameter 00010 was chosen for the X-axis and 

parameters 00025, 00095, and 00915 were chosen for the Y-axis, the following 

data would be displayed: 

P 00010 00025 00095 00915

T plot title in columns 3-42 (optional) 

X Temperature, water 

Y 1 Air pressure 0 POINTS

H 00010 00025 00010 00025 00010 00025

Y 2 Specific cond at 25C 2 POINTS

END OF DATA

o The next queries allow you to customize the plot title and axes labels. 

o Finally, you have the option of connecting the plot points with lines. 

o A separate TKG2 window should appear on your screen. From that window you 

can select the output format by selecting the ‘TKG2 Displayer’ button to see your 

output options. 

The output options are printing the plot, saving the plot as a TKG2 control file, or 

export the plot into a Framemaker Interchange Format (mif), portable document 

format (pdf), portable network graphics (png), or postscript (ps) file. 

Any TKG2 or G2 files that are made can be manipulated outside of QWDATA by 

using TKG2. All files that are produced will be available in your working 

directory.

o When your output option is completed, you should use the ‘Exit’ option from the 

TKG2 Displayer window and then return to the Unix screen. Enter <CR> in that 

window and you will be returned to the applications menu.

o You should check that your UNIX DISPLAY environment variable is set 

correctly. If you need help with this step, please contact the local system 

administrator.

o The first query is asking for the name of a file of record numbers to identify what 

samples will be included in the plot. All graphical programs require an input file 

of record numbers to operate. The format of this file is one record number per line 

in columns 1-8 and can be generated through QWDATA (see Section 3.3.1) or 

created with an editor. Examples of this input file are shown in Appendix G.

5.19 Tip Sheet: How can I round my results in QWDATA output?

 Rounding of values in table or flatfile output from QWDATA is controlled from the 

tabling options screen for the output format. The tabling options screen for publication format 

tables is shown below as an example:

( 1) Limit Results by DQI Code: X_Public accessible [ASR] __User Specified 

( 2) Parameter Order: X_Publication Order __As Supplied 

( 3) Rounding of Result Values: __None __User X_Default

( 4) Censoring of Zero Values: X_None __User Specified 

( 5) Recensoring of Values: X_None __User Specified 

( 6) Qualifiers in Output: __Yes X_No 

( 7) Footnotes: __None X_Remarks __Qualifiers 

( 8) Create Parnames File: __Yes X_No

( 9) Time Datum: X_Watch Time __User Specified 

(10) Restrict parameters: __None X_Public

(11) Display text for fixed values: __Yes X_No 

(12) Calculated-value precedence: X_Stored, calculated __User Specified 

 There are three different ways result values can be rounded upon output from QWDATA. 

Most of the output options use one rounding option for the entire table: 

Default User None

Note: The Office of Water Quality generally recommends that default rounding is used for 

publication of water-quality results from QWDATA, with specific other instructions for 

Radiological results (See Memos 2002.11 and 2008.06 at

http://water.usgs.gov/admin/memo/QW/).

 Default rounding allows the software to employ the use of either the lab standard 

deviation stored with the result value or the rounding array from the parameter-method 

table.

o The laboratory standard deviation can be stored with each result and will be used 

to round the result value if it exists. This value is used with the ASTM E29-93a 

standard to determine the appropriate rounding for the result value. Details of this 

rounding application are available on the Phoenix web page dedicated to rounding. 

To retrieve the laboratory standard deviation, select a by-result output format and use 

the ALPHA parameter code of LSDEV.

o If the laboratory standard deviation is not stored with the result value, the 10-element 

rounding array stored in the parameter-method table will be used. This rounding 

array contains ten elements: nine precision codes that apply to values within specific 

decadal ranges and one element for the maximum decimals (MaxDec) used to display 

any value. The nine precision codes have meanings as follows: 
5.19 Tip Sheet: How can I round my results in QWDATA output?

Water Quality 724 NWIS User

Element Applies to values with absolute magnitude: Meaning of precision 

code

1 less than 0.01 * Number of digits shown 

to the right of the 

decimal. (Eg. A raw 

number of 0.12345 

rounded using a precision 

code of 3 is displayed as 

0.123.

2 less than 0.1 and greater than or equal to 0.01 

3 less than 1.0 and greater than or equal to 0.1 

4 less than 10. and greater than or equal to 1.0 Number of significant 

digits shown. 

Precisions 10 - 16 are 

signified by the symbols 

below: 

10 - : (colon) 

11 - ; (semi-colon) 

12 - < (less than)

13 - = (equal)

14 - > (greater than)

15 - ? (question mark) 

16 - @ (at symbol) 

5 less than 100. and greater than or equal to 10 

6 less than 1,000. and greater than or equal to 100 

7 less than 10,000. and greater than or equal to 1,000 

8 less than 100,000. and greater than or equal to 

10,000 

9 greater than or equal to 100,000 

*Values equal to zero will be rounded using MaxDec, unless replaced by an "M" remark.

 User rounding allows the software to employ the use of a rounding code stored with a result. 

In some instances the default rounding behavior is not desired and user rounding will result 

in a rounded value that is controlled by the user-entered rounding code. The code stored is 

used in the same way as an element from the rounding array described above. If no code is 

stored with the result, the rounding array in the parameter-method table will be used. 

Note: Historically the stored user-rounding codes have been entered inconsistently and the 

use of this option may result in undesired output.

 No rounding will result in the value being included in output in the same way it is stored in 

QWDATA.

Note: Data output with no rounding may be useful for plots to avoid step patterns in the data.

 The Publication Export output option allows the use of more than one rounding option in a 

table, by employing rounding on a parameter code basis if the user selects “custom” rounding 

(see Appendix G for input format).
5.19 Tip Sheet: How can I round my results in QWDATA output?

Water Quality 725 NWIS User

Reminders about rounding in QWDATA output: 

If an ‘M’ appears in place of a result in the output, the program has identified that the result will 

round to zero. If a zero is not allowed for that parameter, an ‘M’ is included. A separate flag in 

the parameter reference table indicates whether a zero is allowed for a specific parameter. Check 

Appendix I for a complete listing of parameters that are not allowed to have a zero result.

o Fixed-value parameters (e.g. sampling method, sampler type, purpose of site visit) 

will not be rounded. 

o If the rounding of the results does not seem correct, please enter a GNATS report 

with the details of the output. Details on how to enter a GNATS report are included in 

Tip Sheet 5.16.

Laboratories may supply a rounding code that is slightly different than those used in NWIS. 

Please contact the laboratory for details about the rounding codes used. 

Note that NWQL uses a similar but not identical rounding array. The NWQL array has 7 

elements corresponding to elements 1-7 of the NWIS array. NWQL elements 1-3, however, 

represent the number of significant digits to be shown. Thus a value to be displayed as 0.012 

carries a precision code of 2 at NWQL and 3 in NWIS.

Water Quality 726 NWIS User

5.20 Tip Sheet: How do I change data quality-indicator codes?

Because the review status of a result changes through time, an application in QWDATA was 

designed to help users set data quality-indicator (DQI) codes. See Section 3.7.6 for a complete 

description of this process. By default, data are entered into QWDATA with a DQI code of “S,” 

presumed satisfactory. After data are reviewed, their status is either “approved” or “rejected.” 

Water-quality data typically are reviewed and published annually as part of the Annual Water 

Data Report. Therefore, DQI codes typically need to be changed on at least annually, although 

more regular updates of the review status are encouraged.

A DQI code will: 

• indicate the review status of a result, 

• affect whether the result will be included in the retrieval of output and displayed to the 

public via NWISWeb Interface, 

• control the ability of the batch software to overwrite a value, and 

• impact the display or output of algorithm-calculated values.

The list of valid DQI codes is in Appendix A, Table 9. A discussion of how DQI codes are used 

during retrieval of output is in Section 3.4. Details on how DQI codes affect batch processing are 

in Section 3.8. 

 For a small amount of result updates 

o DQI codes can always be changed on a result-by-result basis by using the regular 

QWDATA edit program. See Section 3.2.1 or Tip Sheet 5.5.

 For larger-scale result updates

o Frequently, a large data set for a project or a water year will be approved at once. 

Updating DQI codes for large data sets is usually done by the database 

administrator, water-quality specialist, or an experienced project chief. 

o It is best to begin with a file of record numbers, although this is not required, 

because the program will accept input to the screen. See Tip Sheet 5.15, then, 

from the main QWDATA menu, select Option 7—Utilities. 

o From the Utilities menu, select Option 6—Set Data Quality-Indicator (DQI) 

Code. 

o Indicate your source of identifying records (from a file or the screen), or you may 

identify samples for a list of agency codes and station IDs (Section 2.4.2–2.4.3) 

for a range of dates.

 You can select to change DQI codes for all parameters and method codes in the samples 

or for only specified parameters and methods. Input specific parameter-method pairs 

from the screen or a file (file format is given in Appendix G.) 
5.20 Tip Sheet: How do I change data quality-indicator codes?

Water Quality 727 NWIS User

 There are eight options for remapping DQI codes, including a user-specified option. The 

typical records approval is Option 1, where data change from DQI=S, presumed 

satisfactory, to DQI=R, reviewed. A report will be generated listing the remapping of 

DQI codes that will occur. You are given an opportunity to review the report before the 

changes are made in 

QWDATA. You may want to review this report in another UNIX window, so you can 

return to the same place in the DQI application. 

 Finally, the application will ask if you want to update the results. If you approve the 

remapping after your report review, answering “Y” to the prompt will update the DQI 

codes for all of the data that you specified. 
5.21 Tip Sheet: How do I rapidly determine discharge for surface-water-quality samples?

Water Quality 728 NWIS User

5.21 Tip Sheet: How do I rapidly determine discharge for surface-water quality 

samples?

Water discharge is an important measurement to include with surface-water quality sampling 

results, and it is normally included as one of the parameters in water-quality data publications. 

Water discharge at the time of sampling can be obtained from time-series records at surfacewater data-collection sites equipped with an automated gage-height recorder. The QWDATA 

system includes a program for selecting the appropriate discharge for water-quality sampling 

events from the time series of instantaneous or daily-discharge values. The program may be 

started by using Option 8 of the QWDATA Applications menu or noninteractively from the 

UNIX command line, with syntax shown below (options enclosed in brackets). 

qwdischarge [--database NWISZZ] [--db_no num] [--record_file filename] 

 [--output_file filename] [--output_format rdb or print_ready] [--help] 

The interactive menu method is suitable for a small number of computations. See Section 3.5.8

for the menu option behavior. Otherwise, use the command line noninteractively, for example: 

qwdischarge -db_no 01 -record_file qwrec -output_file q.rdb -output_format 

rdb &

A file containing the record numbers of the samples needing discharges is required (“qwrec” in 

the example). Record numbers are listed one per line, optionally concatenated with a database 

number. If a record number that does not exist in the database is specified, the program will print 

a message like the one below, and continue to process subsequent record numbers. 

Entry on line 2052 does not exist: 01002379

Many projects will have a record-number file for the relevant samples. Users performing an endof-year compilation of data may need to assemble a list of potential record numbers. The SQL 

query below shows how to obtain the record numbers of all samples collected since September 

30, 2009, at sites with the capability to store a discharge time series (aka a “data descriptor” 

record, see the ADAPS manual, section 3.2.3). 

tsql nwishq -Gnwis_select "select distinct record_no from QW_SAMPLE_01 a, 

SITEFILE_01 b, LOC_01 c, DD_01 d where a.sample_start_dt > '30-sep-2009' and 

a.agency_cd = b.agency_cd and a.site_no = b.site_no and b.site_id = c.site_id 

and c.loc_id = d.loc_id and d.parm_cd = '00060'" >qwrec

For each sample (record number) specified, the program will attempt to look up the most 

appropriate discharge value from the time-series records. Initially, the program will attempt to 

find an unremarked instantaneous discharge value for the site that is closest in time to the waterquality sample. The program will search no further than 30 minutes of the sample collection 

time. Failing to find an appropriate instantaneous discharge, the program will search for a mean 

daily discharge. A number of circumstances may occur that cause the program to not find an 

appropriate discharge for a sample. Examples of this are listed on the following page. 
5.21 Tip Sheet: How do I rapidly determine discharge for surface-water-quality samples?

Water Quality 729 NWIS User

 Discharge is not provided for composite samples (sample-end date is specified).

 No discharge is determined if no “primary data descriptor” has been defined in ADAPS. 

 Instantaneous discharge is not determined for samples precise only to the day, and no 

discharge is provided if sample-date precision is less than day-of-month. 

 If the daily mean discharge remark code is “1” or “e” (write protected or estimated), then 

the daily mean is reported, because the instantaneous discharges may be inaccurate.

 If the instantaneous discharge remark code is nonblank, and the daily mean discharge 

remark code is blank, then the daily mean is provided. 

 If no instantaneous discharge is possible, and the daily mean discharge is remarked with 

“2,” “E,” “&,” “>,” or “<,” then no discharge is determined. 

 A warning message is printed if the daily mean discharge was computed in a different 

time datum that the water-quality sample. 

 Neither sample medium nor site type is used to control discharge determinations. 

If a tab-delimited RDB file is output, the following columns are presented (--output_format 

rdb).
