The National Stream Quality 

Accounting Network ( NASQAN)-

Some Questions and Answers 

By JOHN F. FICKE and RICHARD 0. HAWKINSON 

INTRODUCTION 

One of the major new efforts of the U.S. 

Geological Survey is the National Stream Quality Accounting Network (NASQAN). This circular is intended to answer some of the fre-. 

quently asked questions concerning concepts 

used in establishing NASQAN, its purposes, 

design, value, and future plans. 

PURPOSE 

What is NASQAN? 

NASQAN is a series of stations at which 

systematic and continuing measurements are 

made to determine the quality of the Nation's 

streams. Design of the network specifies measurement of a broad range of water-quality 

characteristics which were selected to meet 

many of the information requests of groups 

involved in planning and management on a 

national or regional scale. The primary objectives are (1) to account for the quantity and 

quality of water moving within and from the 

United States, (2) to depict areal variability, 

(3) to detect changes in stream quality, and 

( 4) to lay the groundwork for future assessments of changes in stream quality. 

Why is it needed? 

Data of the type needed to determine longterm trends in the physical, chemical, and biological characteristics of the Nation's surface 

waters are relatively sparse. Wolman (1971) 

and Enviro Control (1972) have documented 

the problems associated with the assessment 

1 

of changes in characteristics of surface waters. 

Wolman stated some fairly obvious problems 

involving statistical analysis of water-quality 

data· these include (1) the relatively short 

lengt'h of hydrologic records, (2) changes in location and frequency of observations, (3) tbe 

fact that comparisons of specific variables related to surface-water quality require systematic correlation with hydrologic behavior, and 

( 4) the fact that knowledge of temporal variability of a specific constituent is often essential to the detection of a trend. Enviro Control's study verified the existence of the first 

problem, noting that of 70,000 stations in the 

Environmental Protection Agency's waterquality data-storage system, only 142 stations 

had 8 or more years of records of samples 

taken as frequently as at quarterly intervals. 

Another problem is the unbalanced areal distribution of existing stations having adequate 

data for statistical analysis. Seventy percent 

of the stations used in the Enviro Control 

study were in the northwestern and northeastern United States. Steele and others (197 4) 

noted a deficiency of stations in the northcentral and southeast United States. With continued operation of the series of stations established under NASQAN, a set of systematically 

collected baseline water-quality data will be 

available for nationwide studies involving transport of and changes in ·chemical constituents 

in surface waters. 

NASQAN also will provide data needed to 

assess regional trends in order to evaluate the 
effectiveness of programs to control water 

quality. Such assessments will provide local 

and State officials with some of the information required to judge whether revisions 

in programs or new legislation is needed. 

However, the broad-scale information from 

N ASQAN is not likely to be detailed enough 

to assess the effectiveness of pollution-control 

measures on a localized basis, as prescribed by 

Public Law 92-500. Enough insight should be 

supplied by the NASQAN data, however, to 

identify problem areas which require detailed 

monitoring of subbasins to evaluate the effects 

of land use and treatment measures. 

How are NASQAN stations different from those that 

have operated for many years? 

Stations in NASQAN are different in that 

they form a nationwide network in which station location was based upon hydrologic subdivision of river basins. This assures fairly uniform coverage of the entire United States, 

including Puerto Rico. NASQAN stations can 

be further characterized by the facts that a uniform operational design has been designated 

and station operations are committed to fulfilling the long-term obje·ctives of detection of 

trends in water quality. 

In the past, it has not been possible, on a 

nationwide basis, to determine areal differences 

and (or) changes in water quality over time 

because most data-collection programs have 

been operated to satisfy local objectives or objectives of special programs. Consequently, the 

stations have been operated for short periods, 

have been moved frequently, and have experienced variation in constituents sampled. However, it should be noted that many of the stations specified in NASQAN were previously 

operated for other programs and that some 

historical data exist for certain chemical constituents (primarily the common constituents) 

that will be useful in evaluation of trends. Unfortunately, most previous data~ollection programs did not monitor the suites of constituents 

(nitrogen and phosphorus species, bacteria, 

minor elements, organic indicators, and biological parameters) that are of primary concern 

in establishing the suitability of water for a 

given use. The N ASQAN program, :as designed, 

will help to eliminate this deficiency as well as, 

in time, some of the problems which Wolman 

2

(1971) discussed; notably, establishing the 

data base needed for nationwide evaluation of 

trends in quality of surface waters, and the 

need to account for the movement of materials 

in surface waters. 

In addition, NASQAN will use other agencies' documentation of the man-induced changes 

that occur within basins to help explain changes 

that may occur in water quality. Water-quality 

data from adjacent nonnetwork stations and 

other environmental data will also be used in 

the analyses and interpretation of NASQAN 

data, particularly where changes in the waterquality characteristics of a river are detected. 

Who began NASQAN? 

NASQAN was established by the U.S. Department of Interior, Geological Survey. The 

initial need for a national network to provide 

water data for Federal agencies was recognized 

in Bureau of the Budget Circular A-67, dated 

August 28, 1964. The circular stated that the 

national network is the mechanism for providing data on the quantity and quality of surface water and ground water, including sedi-

ment load of streams, and it assigns the responsibility for network operation to the Department of the Interior. The Office of Water 

Data Coordination of the U.S. Geological Survey was designated by the Secretary of the Interior to design and coordinate the National 

Water Data Network. 

As a basis for network design activities, the 

Office of Water Data Coordination used the 

"level-of-information concept" to specify three 

categories (levels I, II, and III) into which 

data-collection activities can be classified 

(Langford and Davis, 1970). Level I data constitute a basic level of information nationwide 

and thus are suitable for broad national and 

regional planning and as a foundation for more 

detailed work in the future. 

The need for a national river-quality accounting network to provide broad-scale accounting 

data (Office of Water Data Coordination level 

I information) was a primary component of a 

Departmental "thrust document" on river-quality monitoring in March 1972. On the basis of 

this impetus, NASQAN became an official activity of the Geological Survey. 

3 

Data-collection activities were either initiated or upgraded at 50 stations in January 

1973, and at another 50 s·tations in January 

197 4, to meet the design specifications for network operation. Appropriations during ihe 

1975 fiscal year permitted expansion to at least 

one station in each unit of the level I accounting network, thereby placing the present level 

of network operations at 345 stations. 

ACCOUNTING NETWORKS 

What are the geographical units used in level I 

accounting? 

Through the Water Resources Planning Act 

of 1965 (PL 89-80), the Water Resources Council was established to provide a framework that 

would facilitate coordination of water-resource 

and land-resource activities. In compliance 

with this charge, Water Resources Council 

(1970) divided the United States into waterplanning regions and subregions. The U.S. 

Geological Survey's Office of Water Data Coordination has carried the division one step 

further by specification of accounting units. 

Figure 1 outlines the existing 21 regions and 

324 accounting units in the United States.

FIGURE !.-Outlines of the 21 regions and the 324 accounting units as defined by the U.S. Water Resources Council and the Office of Water 

Data Coordination (U.S. Department of Interior, Geological Survey). 
The Office of Water Data Coordination is 

presently rev1smg certain accounting-unit 

boundaries, using input from other Federal, 

State, and local agencies. Revisions receive approval from the Water Resources Council before 

publication of base maps (Hydrologic Unit Map 

-1974, U.S. Geological Survey, issued by 

State) bearing the hydrologic subdivisions. 

Accounting units in New England are shown 

at a larger scale (1: 5,000,000) in figure 2 to 

illustrate in greater detail than in figure 1 

how stream drainage patterns influence selection of station locations. Figure 2 shows that 

accounting units along coastlines are drained 

by numerous streams flowing into the sea; 

similar situations exist along the shores of the 

Great Lakes. In inland accounting units, however, most of the outflow drains by single 

streams. 

How are NASQAN stations located within accounting units? 

Guidelines for level I accounting that have 

been established specify that data will measure 

water discharge and water quality for approximately 90 percent of the surface water leaving 

an accounting unit. This means that most 

NASQAN stations will measure or account for 

discharge and quality at a stream station near 

the downstream end of each accounting unit. 

Obvious exceptions must be made for units that 

discharge to the oceans or to the Great Lakes, 

across international boundaries, or into closed 

basill8. Current revisions of accounting-unit 

boundaries have been reviewed and apparently 

have little affect on the locations of stations 

specified in 1972 for inclusion in the network. 

How are stations in coastal units selected? 

As figure 2 shows, some units stretch along 

coastlines (oceall8 or the Great Lakes) where 

numerous stations would be needed to sample 

90 percent of the flow. This problem has been 

recognized in the design of NASQAN, and 

special criteria have been established for selecting station locations within coastal accounting 

units. NASQAN stations have been located to 

provide a sampling of from 30 to 50 percent of 

the water flowing from the coastal accounting 

unit. Such sampling is possible because adjacent 

drainage basins usually have similar physio5

graphic and hydrologic characteristics. Therefore, it may reasonably be inferred that waterquality data from properly selected stations 

may be extrapolated to represent the remainder 

of the discharge. In choosing sites for stations, 

short-term reconnaissance studies are needed 

to confirm similarity of waters. It is also necessary to recognize and evaluate obvious differences in such parameters as population patterns, geology, or industrial development. 

How are sites selected for stations in closed basins? 

Accounting units with only interior drainage 

have been considered on a case-by-case basis in 

the selection of NASQAN station locations. The 

principal policy has been to select sites on 

streams that represent as much of the drainage area of or flow within the accounting unit 

as possible.

OP·ERATION 

How many stations are in NASQAN and where are they? 

As of January 1, 1975, 345 NASQAN stations were being operated. As stated earlier, 

the plan used in selecting l~tions of existing 

and future stations calls for most of them to 

be near the points of outflow from ac-counting 

units. Locations of the current 345 stations 

are shown in figure 3. Details of station location, including the names of towns or other 

cultural features near the stations, and latitudes and longitudes are given in table 1 (see 

p. 15). 

Plans call for NASQAN to reach its final design size of 525 stations by October 1976. Figure 4 summarizes the network's past growth 

as well as the projected expansion to full implementation. 

What water-quality characteristics are measured at 

NASQAN stations? 

The following list summarizes the characteristic·s measured at network stations and the 

minimum frequencies of measurements under 

present network design.

have been established between conductance and concentrations of 

various common constituents. 

4 Total concentrations are those determined by analyses of unfiltered samples. They include both dissolved and suspended materials. 

In addition to the measurements shown 

above, determinations of pesticide residues and 

radiochemical constituents are made at selected stations. These stations can be viewed 

as subnetworks of NASQAN. 

Will changes be made in the suite of characteristics 

measured at NASQAN stations? 

Yes, but in a manner that conforms with the 

stated objectives of the network. A continual 

examination will be made for correlations 

among measured characteristics. If correlations are established so that changes in one 

characteristic can be used to estimate changes 

in others, certain measurements may be discontinued. Also, some measurements may be 

added as water-quality characteristics change 

in importance. Consideration presently is being 

given to including two 24-hour dissolved oxygen 

profiles each year, to be conducted during critical periods ; to monthly determination of ammonia nitrogen; and to an increased frequency 

of determination of total organic carbon, from 

quarterly to monthly. Any such adjustments 

in the operational design of the network will 

be made to coincide with the beginning of a 

water year (October 1). 

Who collects data at NASQAN stations? 

Most of the NASQAN data are and will be 

collected by the Geological Survey. However,

some of the stations are operated partly by 

other Federal agencies, such as the Environmental Protection Agency and the U.S. Army 

Corps of Engineers, and some are operated 

partly by State and local organizations. For 

those stations operated by the Geological Survey, some are paid for partly by monies from 

other Federal agencies, from State and local cooperators, and from other more specialized Federal data-collection programs of the Geological 

Survey. Because of local interests or needs, it 

is not uncommon to have several different 

sources interested in and paying for total operations of a single station. 

10 

How long will stations be operated? 

Indefinitely, as required by one of the network objectives-to assess changes in water 

quality with time. However, some changes in 

operating practices will be made, as explained 

previously in answer to a question regarding 

changes in the suite of characteristics. Such 

changes will be made only after it ha.s been determined that the proposed modification, presumaJbly a change in frequency of sampling, 

will not affect the fulfillment of network objectives.

What will be done with the data? 

Present plans call for data collected under 

the auspices of N ASQAN to be published in 

three types of publications. 

First, all data will be published in the annual Geological Survey basic-data reports on 

a State-by-State basis. Copies of these reports 

can be obtained from Geological Survey district offices or from Geological Survey headquarters, Reston, Virginia 22092. Users of 

STORET, the computerized data base of the 

Environmental Protection Agency, can retrieve 

11 

NASQAN data by using Geological Survey 

station numbers (see table 1). 

The second type of report is an annual summary report depicting the Nation's surfacewater quality. This report, the prototype of 

which should be completed by August 1975, 

will use ta;bulations of the yearly range in concentrations of specific constituents, statistical 

summaries, and graphical presentations. 

The third type of report, which will be more 

analytical, will deal with the changes (or lack 

thereof) in water quality. Preliminary work by 
the Geological Survey (Steele and others, 

1974) employed an approach which may be used 

to ·evaluate trends in water quality. This type 

of report will be prepared less frequently 

(every 3 to 5 years) . 

NASQAN interpretive reports (the second 

and third types) will be published in forms 

suitable for use by hydrologists as well as nontechnical persons. 

What will be the principal problems in the interpretation 

of the data? 

Undoubtedly there will be several problems 

in dat~a interpretation, but two will probably be 

hardest to resolve: (1) Differentiating yearto-year variability (wet-year, dry-year effects) 

from the long-term trends and from the real 

areal differences in variables significantly affected by flow conditions, ·and (2) adjusting 

for the effects of streamflow regulation (particularly by reservoirs) or streamflow diversions on the water-quality conditions. 

To resolve the first problem, several statistical 'and other analytical techniques are being evaluated to discover their utility in determining significant long-term trends from 

the data. For some w·ater-quality characteristics, 5 or more years of data may be needed before adequate bases exist for detecting longterm trends. 

Regarding the second problem, reservoirs 

are particularly significant because they alter 

the pattern of streamflow during the year and 

also influence many water-quality characteristics. Seasonal streamflow patterns are affected 

by patterns of reservoir release, but the annual volumes of flow usually do not change, 

except for evaporation losses. The quality of 

water released from reservoirs differs from 

that of inflow, in terms of temperature, dissolved solids, sediment, nutrients, dissolved 

oxygen, and other characteristics. There is 

much literature describing the processes that 

take place in reservoirs, but quantitative modeling is not far enough advanced to be helpful 

in determining the precise degree to which the 

reservoirs will affect water quality at N ASQAN 

stations. 

What is the policy regarding NASQAN stations near 

reservoirs? 

The lower boundaries of many of the accounting units used to establish the hydrologic 

design of N ASQAN cross stream channels at 

or just below dams. Because an objective of 

the network operation is to account for the 

quantity and quality of water actually flowing 

from one accounting unit into another, the 

placement of sampling stations below reservoirs is necessary. On the other hand, 

N ASQAN's goal of interpreting changes in 

water quantity and quality in terms of cultural 

changes in the basin is not fully served qy a 

station located below a reservoir because the 

effects of the reservoir will mask most other 

influences. Therefore, operation of NASQAN 

will involve evaluation of the effects of some 

reservoirs by placing secondary stations above 

several large reservoirs. These stations ~are referred to ~as secondary because they will be used 

to collect a more limited suite of data and probably will operate for a limited number of years. 

SUMMARY 

N ASQAN is designed to describe the water 

quality of the Nation's streams and rivers on 

a systematic and continuing basis. NASQAN 

station operation supplements the ongoing activities of the U.S. Geological Survey and other 

agencies. Whereas other operations meet local 

and short-term needs, N ASQAN provides for 

nationwide quantitative descriptions of the 

physical, chemical, and biological characteristics of streams. There presently are 345 stations in the network, and network design allows 

for an ultimate size of 525 stations.
