National Summary of 

Public Water Systems Compliance in 2006 

INTRODUCTION 

The National Public Water Systems Compliance Report 

for 2006 describes how the Environmental Protection 

Agency (EPA) and its state and tribal partners are meeting 

the goal of ensuring that Americans receive safe drinking 

water from public water systems. 

One of the ways that EPA measures attaining this goal is to 

track the number of public water systems that may not be 

meeting health-based drinking water standards, or 

monitoring and reporting requirements. 

In 2006, 93% of America’s public water systems 

did not have any reported violations of healthbased standards. 

Public Water Systems 

A Public Water System (PWS) is a system that 

provides water for human consumption, if such system 

has at least 15 service connections or regularly serves 

at least 25 individuals at least 60 days out of the year. 

EPA doesn’t have the authority to regulate private 

drinking water wells that do not meet the above 

criteria. A public water system can be one of three 

types: 

•	 Community Systems (CWS) serve at least 15 

service connections (which may include factories, 

schools, or places of housing that are on the same 

distribution system as residences) used by yearround residences or regularly serve at least 25 yearround residents. 

•	 Non-transient Non-community Systems 

(NTNCWS) serve at least 25 of the same persons 

over six months per year not at their residence (e.g., 

schools or factories that have their own water 

source). 

• Transient Non-community Systems (TNCWS) 

serve at least 25 persons (but not the same 25) over 

six months per year not at their residence (e.g., 

campgrounds or highway rest stops that have their 

own water source). 

EPA prepares a National Public Water Systems 

Compliance Report for every calendar year. This report 

uses a calendar year, which is from January through 

December, while other reports or databases may use the 

fiscal year which is from October through September. The 

federal report is an annual summary of reported violations 

at the nation’s public water systems. This report discusses 

the data we use to measure our success and the progress 

we are making in our efforts to increase data reliability and 

completeness. The report also summarizes and evaluates 

annual reports prepared by the states.1 

The first part of this report provides a national picture of 

public water system compliance using data from the Safe 

Drinking Water Information System/Federal Version 

(SDWIS/FED). SDWIS/FED is the national database 

where states and tribes with primacy report annually to 

EPA violations of the maximum contaminant levels, 

treatment techniques, monitoring and reporting, consumer 

notification, and variance and/or exemptions. EPA 

aggregates these reported violations at all public water 

systems in states, commonwealths, territories and in Indian 

country to present a national summary of violations, and 

then presents summaries of significant monitoring and 

reporting violations, significant public notification 

violations, and violations of health-based standards at the 

different kinds of public water systems. 

The second part of this report presents information on 

public water systems in Indian country. A glossary of 

terms used in this report appears in Appendix A. 

Summaries and evaluations of completeness of the states’ 

annual public water systems reports for 2006 are presented 

in Appendix B. 

The term “state” includes 57 states, commonwealths, and territories that have been approved to implement the drinking water program within their 

jurisdiction. It also includes the Navajo Nation, which received EPA approval to implement its drinking water program on December 6, 2000. Federal approval 

to implement the drinking water program is called primary enforcement authority, or “primacy.” During calendar year 2006, EPA directly implemented the 

drinking water program in Wyoming, the District of Columbia, and throughout most of Indian country other than the Navajo Nation. EPA is responsible for 

reporting violations in areas where the Agency directly implements the program.

_________ 

How Does The Public Find Out If Its Drinking Water Is Safe? 

Information Sent to Customers: 

Consumer Confidence Report — 

(http://www.epa.gov/safewater/ccr/pdfs/quickrefguide 

_ccr.pdf) Every community water system is required to 

produce a yearly report identifying the contaminants detected 

in its water and the risks of exposure to those contaminants. 

The annual water quality report or consumer confidence 

report (CCR) tells customers what is in their water, where it 

comes from, and where they can obtain additional 

information. Large systems are required to mail the report to 

their customers. While medium systems and small systems 

are required to produce the report, these systems may obtain 

a waiver from the mailing requirement. Very small systems 

are only required to print the report in the local newspaper. 

Public Notification Rule — (http://www.epa.gov/ 

safewater/pws/publicnotificaton/index.html) Public water 

systems must notify their customers if there has been a 

violation of drinking water standards. Public notification is 

intended to ensure that consumers will always know if there 

is a problem with their drinking water. Public water systems 

must notify the people who drink their water if the level of a 

contaminant in the water exceeds EPA, State, or tribal 

drinking water regulations, if there is a waterborne disease 

outbreak or any other situation that may pose a risk to the 

public health, if the water system fails to test its water as 

required, or if the system has a variance or exemption from 

the regulations. Depending on the severity of the situation 

water suppliers have 24 hours to one year to notify their 

customers. Public notification is provided in addition to the 

CCR. 

Information on the Internet: 

Safewater Web Site (http://www.epa.gov/safewater) — 

Provides information on the Safe Drinking Water Act, 

individual water systems, contaminants that may be in 

drinking water, and what individuals can do to help protect 

sources of their drinking water. 

Additional Information: 

Call the Community Water System — Billing statements 

should provide a number to call with questions. 

State Public Water Systems Compliance Report — Each 

state’s annual report discusses the violations at its public 

water systems. Most state reports include a list of violating 

facilities. 

National Public Water Systems Compliance Report (this 

report) — Summarizes all reported violations at America’s 

public water systems. 

Safe Drinking Water Hotline (1-800-426-4791) — 

Answers questions about drinking water, lets callers order 

documents from EPA, and can refer callers to EPA experts if 

they need more information. 

Envirofacts Web Site (http://www.epa.gov/enviro) — 

Allows the public to access EPA databases containing 

information on environmental activities that may affect air, 

water, and land anywhere in the United States. 

WHAT INFORMATION IS IN THIS 

REPORT? 

This report uses information from SDWIS/FED, the 

national database where EPA records information that the 

states are required to report about their public water 

systems. For the national public water system compliance 

reports, EPA examines SDWIS/FED records of violations 

of primary drinking water regulations that specify: 1) the 

maximum permissible level of a contaminant in water that 

is delivered to any user of a public water system 

(Maximum Contaminant Level or MCL); 2) techniques for 

treating water (TT) to make it safe; 3) monitoring and 

reporting requirements (how and when water must be 

tested and the results reported); and 4) significant user 

notification violations. 

•	 While SDWIS/FED collects information on all 

monitoring and reporting violations, only significant2 

monitoring and reporting violations are counted in this 

report. A “significant” monitoring and reporting 

violation occurs, with rare exceptions, when no samples 

are taken or no results are reported during a compliance 

period. Table A–1 provides a more detailed description 

of significant monitoring violations for the different 

rules. 

2 This report tabulates only “significant” monitoring and reporting and notification (e.g., CCR) violations. Table A–1 presents descriptions of significant 

monitoring violations for the different drinking water regulations. 

March 2009 • Page 2 2006 National Public Water Systems Compliance Report – National Summary 
•	 A significant user notification violation occurs when a 

community water system completely fails to provide to 

its users a required report. Significant user notification 

violations include violations of the Consumer 

Confidence Report Regulation and violations of the 

Public Notification Regulations. 

•	 The information provided in the Consumer Confidence 

Report (CCR) will supplement public notification that 

water systems must provide to their customers upon 

discovering any violation of a contaminant standard. 

The CCR typically will provide customers with a 

snapshot of the quality of their drinking water supply. 

•	 Public notification helps to ensure that consumers 

receive timely information about problems with their 

drinking water. These public notification requirements 

have always been a part of the Safe Drinking Water Act, 

but were revised in 2000. 

EPA routinely evaluates state programs by conducting data 

verification audits and triennial national data quality 

assessments. The most recent triennial review revealed that 

81% of the apparent MCL/treatment technique violations 

and 29% of the apparent monitoring and reporting 

violations had been reported to SDWIS/FED. Since the 

reviews, EPA and the primacy agencies have worked 

towards the identification and resolution of any problems 

that may have produced data discrepancies in the past, and 

to prevent the occurrence of future problems. More 

discussions of data quality concerns, triennial reviews, and 

EPA’s recommendations appear later in this report. 

FINDINGS 

Public Water System Sizes and Types 

Public water systems can be categorized based upon the 

size of the population that they serve. Large systems serve 

over 10,000 users, while medium size systems serve 3,301 

to 10,000. The small systems serve 3,300 or less users. 

In 2006, 156,182 public water systems together served 

over 304 million users. The actual number of individuals 

served was smaller, because millions of Americans drank 

water from, and were counted as users by, more than one 

public water system during the course of the year. 

94% of America’s public water systems served 3,300 or 

fewer users. Together, these 147,060 small systems 

provided service to only 13% of all users, while the 4,103 

large systems (3%) provide service to 77% of all users.

schools, factories) served over 6 million people in places 

they frequented. 

•	 85,036 transient non-community systems (i.e., 

campgrounds, highway rest stops) served a constantly 

changing user base of almost 14 million people. Nearly 

all of these systems are small systems.

3 Because approximately 3% of public water systems are “medium” in size, i.e., serve between 3,301 and 10,000 users, and because approximately 10% of the 

population is served by them, this report omits a separate discussion of “medium” systems. Discussions concerning medium systems are included with the 

larger systems.

For 73% of the public water systems in America, serving 

73% of the users, the states reported no health-based 

violation or significant monitoring and reporting violation. 

The states reported either a health-based violation, a 

significant monitoring and reporting violation, or a 

significant CCR violation at 42,108 public water systems 

in 2006. 

No violations of variances or exemptions were 

reported by the states to SDWIS/FED during 2006. 

•	 Under Federal law, states can grant variances or 

exemptions to public water systems in limited 

circumstances allowing them to install alternative 

technology or giving them more time to meet a standard 

if public health is adequately protected in the interim. 

For the few public water systems that were operating 

under a variance or exemption in 2006, no states 

reported a violation of the variance or exemption. 

Health-Based Drinking Water Standards 

93% of America’s public water systems, serving 

90% of the users, did not have any reported 

violations of health-based drinking water 

standards in 2006.

the Total Coliform Rule (TCR) is the health-based 

standard most frequently violated. Over fifty percent 

(53%) of these violations were violations of the MCL for 

the Total Coliform Rule (TCR), which must be met by all 

types and sizes of public water systems.4

If a system did not monitor the quality of its water, it is 

impossible to know if it has violated a health-based 

requirement. For this reason, a system’s significant failure 

to monitor and report is a major violation that must be 

addressed and corrected.

•	 71% of the 128,666 violations the states reported to 

SDWIS/FED in 2006 were for a public water system’s 

significant failure to monitor and report, rather than a 

violation of a health-based standard. 

•	 49% of the 91,077 significant monitoring and reporting 

violations reported by the states were violations of the 

requirements of the Chemical Contaminant Group. In 

2006 the states reported 62% more Chemical 

Contaminant Group monitoring and reporting violations 

than in 2005. This is due to the cyclical pattern of the 

monitoring requirements of the Chemical Contaminant 

Group (See page 11).

•	 73% of the population served by community water 

systems received drinking water from a system with no 

significant state-reported violations. 

•	 Of the more than 8,000 larger community water systems 

approximately 2,300 (27%) had significant violations 

reported by the states. Of the 43,372 small community 

water systems, 16,785 (39%) had significant violations. 

•	 As reported by the states to SDWIS/FED, 86% of the 

community water systems complied with the Consumer 

Confidence Rule. 

4 For the annual compliance reports, EPA tracks violations of the contaminant rules in five categories: 1) chemical contaminants (Chem) — violations 

of rules for organic, inorganic (except for lead and copper), and radioactive contaminants — compliance with many organic and inorganic standards is 

determined on the basis of shared samples, with one missed sample resulting in a monitoring and reporting violation of many standards; 2) total coliform 

rule (TCR) Coliform bacteria are usually not a threat to humans, but their presence in drinking water can indicate a lapse in treatment and the possible 

presence of other, more dangerous microbes.; 3) lead and copper rule (LCR); 4) surface water treatment (SWTR) includes interim enhanced surface 

water rule (IESWTR), filter backwash recycling rule; Long Term Enhanced Surface Water Treatment Rule; and 5) Disinfection By-Product Rule 

(DBPR).

Does a Health-Based Violation Mean Drinking the Water Causes Illness? 

It is important to note that a public water system’s violation Recognized and reported waterborne disease outbreaks are

drank the system’s water got sick. A health-based violation cause acute gastrointestinal illness with diarrhea, abdominal

indicate that between 1980 and 1998 there were 419 also for populations that are at greater risk from waterborne

Compliance Assistance and Enforcement 

Primacy States and EPA engage in a variety of activities to 

help public water systems remain in and return to 

compliance, including formal enforcement actions, 

informal actions, and compliance and technical assistance. 

State and EPA compliance assistance efforts to help a 

source remain in or return to compliance may include: 

•	 conducting on-site visits and sanitary surveys at public 

water systems (i.e., an on-site review of the water 

sources, facilities, equipment, operations, and 

maintenance to evaluate their adequacy in producing and 

distributing safe drinking water); 

• helping systems invest in preventive measures; 

•	 providing financial assistance for system improvements 

through the Drinking Water State Revolving Fund and 

other State funding programs; 

• reviewing water system plans and specifications; 

• conducting training sessions; 

• holding public information meetings; 

• lending specialized monitoring equipment; and 

•	 publishing informational bulletins and newsletters on 

training events and other educational opportunities. 

2006 National Public Water Systems Compliance Report – National Summary Page 7 • March 2009 
What Happens to Systems that Violate the 

Requirements? 

When a drinking water violation is detected and 

compliance assistance to the violating system is found not 

to be an effective method for returning the system to 

compliance, EPA program implementation guidelines 

require the state, as a condition for receiving EPA funding, 

to initiate an enforcement response. Acceptable 

enforcement responses include a variety of formal and 

informal actions as the state or EPA attempts to return a 

violating public water system to compliance as quickly as 

possible. 

Generally, the primacy agency’s first responses to 

violations are informal actions beyond compliance 

assistance such as: 

• reminder letters; 

• warning letters; 

• notices of violation; 

• field visits; and 

• telephone calls. 

If the violation continues or recurs, the primacy agency 

must initiate a formal enforcement response that requires 

the violating public water system to return to compliance. 

Formal enforcement responses include: 

• citations; 

• administrative orders with or without penalties; 

•	 civil referrals to state attorneys general or to the 

Department of Justice; 

•	 other sanctions, such as denying permission for system 

expansion; and 

• filing criminal charges. 

If a situation poses an imminent risk to public health, EPA 

and the state can issue an emergency order that requires 

the public water system to take the steps necessary to 

protect public health and return the system to compliance. 

During 2006, EPA and its state partners initiated 4,114 

enforcement actions in response to drinking water 

violations at public water systems in their jurisdictions. For 

new rules, EPA generally has primary enforcement 

authority until the States receive primacy for each new 

rule. EPA implemented the drinking water program in 

Wyoming, the District of Columbia, and in Indian country, 

except for the Navajo Nation. The Agency initiated 

enforcement responses in these areas and occasionally in 

the states, often at a state’s invitation.5 

•	 In 2006 the states issued a total of 3,966 formal 

enforcement actions, including: 1,124 administrative 

orders without penalty, 1,428 administrative orders with 

penalty, 102 civil referrals to the states’ Attorneys 

General, 558 signed State Bilateral Compliance 

Agreements (BCA), 744 state intentional no-actions, 4 

civil cases filed, and 6 criminal cases filed. 

•	 During the same period, EPA issued a total of 148 

formal enforcement actions, including 145 federal 

administrative orders, one Federal Emergency Order, 3 

Federal intentional no actions, and 2 signed Federal 

BCA. 

These totals do not include informal enforcement actions 

(i.e., warning letters, notices of violation), compliance 

assistance activities, or the public water systems that 

returned to compliance before EPA and state procedures 

would require initiation of a formal response. 

EPA generally designates a public water system to be in 

significant non-compliance (SNC) if the system has 

serious, frequent, or persistent violations for a specific 

regulation that may pose a threat to public health. This 

enables the states and EPA to prioritize enforcement 

resources to ensure that the most severe violations are 

addressed first. While all systems in SNC are a priority, 

the systems in SNC with health-based violations receive 

even higher attention than those with other violations. In 

EPA’s “timely and appropriate” guidance for drinking 

water, violations that have been elevated to the SNC level 

are to be addressed with a formal enforcement action 

within six months of receiving the SNC designation. EPA 

reviews the state-reported violations quarterly to identify 

new systems as being in SNC for one or more rules or for 

other systems as being addressed SNCs. In determining the 

total number of systems that are in significant noncompliance and have had the SNC addressed, EPA does 

not take into account the public water systems that have 

returned to compliance due to informal enforcement 

actions or compliance assistance, or public water systems 

that have returned to compliance before EPA and the states 

have initiated a formal response. 

•	 Of the 156,182 public water systems nationwide, EPA 

determined that 14,036 systems were in significant 

noncompliance for calendar year 2006. This was 

comparable to the number of public water systems 

determined to be in significant noncompliance in 2004 

and 2005. Over 90% of the public water systems 

determined to be in significant non-compliance are small 

systems serving 3,300 or fewer users. 

March 2009 • Page 8 2006 National Public Water Systems Compliance Report – National Summary 
 

•	 In 2006 states and EPA addressed non-compliance at 

6,035public water systems. Additionally the states and 

EPA addressed 4,157 of the systems with new SNC 

outside of the 2006 calendar year, leaving 3,844 systems 

(over 2% of the systems nationally) with unaddressed 

SNCs. 

It should be noted that this report is a snapshot of one year. 

Systems that are identified as being in significant noncompliance near the end of the year are likely to carry over 

to the next year, since the states have 6 months/two 

quarters to address a SNC. For example, if an average of 

14,000 systems were designated SNCs in a year, then, on 

average, 3,500 systems are designated as SNC in a quarter. 

Since EPA and the states have six months to address 

systems with SNC, as many as 7,000 systems could be 

classified as unaddressed SNCs at the end of a year. 

However, EPA and the states would still be in compliance 

with EPA’s “Timely and Appropriate” response policy 

because EPA and the states have six months to address 

systems with SNC. 

Starting in calendar year 2006 (fiscal year 2007) EPA 

shifted its focus from ensuring SNCs were being addressed 

on a rule by rule basis to ensuring systems with SNC were 

being returned to compliance. Annually, EPA 

Headquarters negotiates the state targets with the Regions 

through the Annual Commitment System (ACS). The goal 

for each state is to reduce its number of drinking water 

systems with significant noncompliance for all rules. Since 

we have adopted that focus we have seen the number of 

systems with SNC decrease from 12,596 systems listed in 

July 2006 to 8,438 listed in July 2008 (a 33% reduction). 

Nationally, EPA headquarters reviews the progress of all 

the states with our Regional offices. Where we have 

identified significant increases of systems with SNC in a 

state, we have asked the region to work with the state to 

address the non-compliance. The state can provide 

compliance assistance to correct the situation, if 

appropriate. In addition, headquarters provides quarterly 

updates for the Regions and states on the status of systems 

with SNC. Using this update of their systems’ status, 

states prioritize any new systems that need to be addressed 

and track their progress towards addressing systems with 

existing SNC. We are also in the process of developing an 

approach for targeting violations that will assist the 

Regions and states to identify systems with serious 

violations more efficiently. The focus of this effort is to 

direct EPA’s enforcement resources more strategically to 

protect public health. 

WHAT IS THE QUALITY OF THE 

DATA EPA USES FOR THIS REPORT? 

The data used in this report came from EPA’s national 

SDWIS/FED database. SDWIS/FED is composed of data 

that primacy states are required to submit to SDWIS/FED 

each quarter. EPA uses information in SDWIS/FED to 

assess progress in the implementation of regulations, to 

develop national enforcement and compliance priorities, 

and to provide information to the public. 

EPA periodically conducts data verifications (independent, 

on-site audits) of primacy state and tribal drinking water 

programs to ensure that the primacy state is determining 

compliance in accordance with Federal regulations. Data 

verifications help detect differences between data in a 

state’s files (whether electronic or hard copy) and data in 

SDWIS/FED. 

As part of the ongoing data reliability efforts described in 

past National Public Water Systems Compliance Reports, 

EPA examined the results of data verifications conducted 

from 1999 to 2001 and previously from 1996 through 

1998. The 2002-2004 audits, which covered 38 states, 

analyzed data from 2,658 public water systems. The data 

audits reviewed inventory information (identifying 

systems, their number, their size, and their type), apparent 

violations that either were reported or should have been 

reported, and any enforcement actions initiated. 

EPA’s review showed that the quality of the information 

the states reported to SDWIS/FED is highly accurate, but 

the data are incomplete. This finding principally reflects 

states’ failure to determine and assign a violation rather 

than a preponderance of data management issues. Most of 

the SDWIS/FED data quality problems EPA identified 

were instances where violations that should have been 

recorded and reported did not appear in SDWIS/FED. EPA 

found that only a small percentage of this incompleteness 

is because SDWIS/FED will accept only properly 

transferred data. EPA’s analysis of the data verifications 

found: 

•	 87% of all inventory data in SDWIS/FED were 

consistently reported. 

5 There are several reasons why there will be a difference between the number of violations in a year and the number of formal enforcement responses. For 

example, a state may choose to address a system’s violations informally in a manner that returns the system to compliance before the time interval has elapsed 

that by EPA guidance would necessitate initiation of a formal enforcement response. Also, it is not uncommon for the regulator to address all of a violating 

system’s multiple violations in a single enforcement response. In addition, formal enforcement responses addressing violations discovered late in one reporting 

year are generally not initiated until early in the following year. 

2006 National Public Water Systems Compliance Report – National Summary Page 9 • March 2009 
•	 The overall quality of TCR MCL violations data in 

SDWIS/FED was 81%, quality of all health-based 

violations was 77%, and quality of monitoring and 

reporting violations was 27%. 

•	 Most of the discrepancies between apparent and reported 

violations are because violations were not reported. 

•	 29% of monitoring and reporting violations had been 

reported to SDWIS/FED. 

•	 81% of the MCL/SWTR treatment technique violations 

had been reported to SDWIS/FED. 

WHAT IS EPA DOING TO 

IMPROVE DATA QUALITY? 

EPA continues to work with its state partners to identify 

and resolve any problems that may have produced data 

discrepancies in the past and to ensure that complete and 

accurate documentation is available to help assess the 

safety of the nations’ drinking water. 

•	 The drinking water violation data improved from the 

1996-1998 timeframe to the 2002-2004 timeframe. EPA 

has completed the Data Reliability Report for the 2002-

2004 timeframe. EPA has set a goal of 90% accuracy 

for data quality and is working closely with the 

Association of State Drinking Water Administrators 

(ASDWA) to implement an action plan that will help the 

drinking water program achieve this goal. 

•	 EPA and a subset of states established a workgroup 

through ASDWA to implement its updated 2006 Data 

Reliability Analysis and Action Plan (DRAAP). 

Implementation of the plan began in 2005 ahead of the 

report release. 

• EPA will be working with all states to implement the 

EPA Order 5360.1 A2 dealing with requirements for 

quality management systems. 

•	 Changes to modernize SDWIS database should reduce 

data quality problems in the future from data entry to 

transmission. SDWIS Modernization focused on 

changes to make the quality checking function available 

to states before they send data to EPA, to provide a data 

entry format consistent with contemporary commercial 

data transfer formats, and to reduce the complexity of 

data entry into SDWIS/FED by standardizing 

processing. 

In 1998, EPA launched a major effort to assess the quality 

of the drinking water data contained within SDWIS/FED 

to respond to concerns regarding incorrect violations in the 

database. EPA enlisted the help of its stakeholders in 

designing the review, analyzing the results for data 

collected by Data Verification (DV) audits between 1996 

and 1998, and recommending actions to improve drinking 

water data quality. The first Data Reliability Analysis of 

SDWIS/FED was published in October 2000. 

Findings of the first Data Reliability Analysis, which 

indicated that data quality needed improvement, were later 

updated by the second and third triennial assessments in 

2003 (which included data collected between 1999 and 

2001) and 2006 (for data between 2002 and 2004). 

Together, these assessments included comprehensive 

recommendations for EPA and state primacy agencies on 

quality improvements. The reports identified near-term 

actions that had already been taken or were still needed to 

improve data quality more immediately. To implement the 

recommendations, the states and EPA have conducted 

numerous activities and projects to improve data quality. 

Activities undertaken have included a) providing training 

for states; b) streamlining reporting to SDWIS/FED; c) 

making SDWIS error reporting more user-friendly; d) 

improving data verifications; e) following up with Regions 

on findings after data verifications; f) encouraging states to 

annually notify water systems of sampling schedules; and 

g) creating an electronic capability to evaluate data quality 

by states and EPA. 

EPA’s response to the data reliability issues identified in 

the 2003 report (second triennial report) included a 

commitment to conduct analyses which would provide 

periodic data quality estimates (DQEs), and provide input 

into program activities and priorities necessary to improve 

the quality and reliability of the data. 

Like the previous two reviews, the third triennial review of 

data quality is largely based on DV audits. The DV audits, 

conducted between 2002 and 2004, reflect data for 2,658 

randomly selected PWSs in 38 states. The introduction to 

the 2006 Drinking Water Data Reliability Analysis and 

Action Plan (EPA 816-R-07- 010, March 2008, available 

online at 

http://www.epa.gov/safewater/data/pdfs/report_data_datar 

eliability_2006.pdf) discusses DV audits and the triennial 

national summary. 

Based on the third review, the overall DQE of the eight 

inventory (water system identification) parameters 

assessed was 87%. In other words, 87% of systems from 

DV states between 2002 and 2004 had consistent data for 

all eight inventory data elements between their state files 

and SDWIS/FED database, or 13% of systems had at least 

one data element reported with a discrepancy. The highest 

discrepancy rate was for the administrative contact address 

element. 

For the 38 states evaluated from 2002 to 2004, 90% of the 

March 2009 • Page 10 2006 National Public Water Systems Compliance Report – National Summary 
reported violations in SDWIS/FED were accurate. 

Approximately 81% of the MCL and SWTR TT violations, 

62% of the health-based violations (including LCR TT 

violations), and 29% of the monitoring and reporting 

(M/R) violations were reported to SDWIS/FED. Nonreporting was mostly attributable to the fact that states did 

not issue violations when violations had occurred 

(compliance determination error). In other words, the 

violations were not recognized, not recorded by the states 

as violations, and consequently, not reported to 

SDWIS/FED. Compliance determination errors led to 

84% of non-reported health-based violations and 92% of 

non-reported M/R violations. 

Additional findings included the DQEs of health-based 

violations were not significantly different between CWSs 

and NTNCWSs. The DQEs of M/R violations for 

TNCWSs were significantly higher than those for CWSs 

and NTNCWSs. 

HOW DOES EPA 

EVALUATE STATE REPORTS?
 

EPA reviewed each 2006 annual state report that was 

submitted to determine if it met the requirements of the 

1996 Amendments to SDWA. The contents of the state 

reports are summarized in Table B–1 in Appendix B. 

Table B–1 shows whether a state: 

• submitted a report to EPA; 

• included all required elements; 

•	 satisfied its statutory requirement to publish and 

distribute summaries of the report that inform the public 

of the availability of the full report; 

• identified the size and type of violating systems; 

•	 discussed the compliance assistance and enforcement 

activities the state undertook in response to violations; 

•	 included a list of PWSs with MCL or treatment 

technique violations, as EPA recommended in its 

guidance to states on preparing their reports; 

•	 provided information to the public on availability of the 

reports; and 

•	 included additional information of interest to the public, 

such as the number of public water systems in the state, 

their sizes and types, and background on the Safe 

Drinking Water Act and its implementation. 

EPA provides a state-by-state summary of information 

reported in each state report in Appendix B. The 

standardized format includes an overall summary of the 

violations data the Safe Drinking Water Act requires states 

to report (i.e., violations with respect to MCLs, treatment 

technique violations, significant monitoring and reporting 

violations, and variances and exemptions). The summary 

for each state also tells how to obtain a copy of the state’s 

full report. The annual summary is based on violations 

reported in the calendar year of 2006. In some instances, 

the data reported by a state in July of 2006 may not agree 

with data currently in SDWIS/FED. EPA’s and the states’ 

continual efforts to ensure that the information in the 

SDWIS/FED database is as accurate as possible may have 

resulted in updates and corrections to the data since the 

state published its report. 

CONCLUSIONS AND 

RECOMMENDATIONS 

Most Americans received water from systems which 

reported no violations of health-based standards, and for 

which the states reported no significant violations of 

monitoring and reporting requirements. 

Comparison of 2005 and 2006 Data 

There are some differences in the numbers of violations 

reported in 2005 and 2006. The total number of violations 

increased by 16% from 2005. The number of significant 

violations of monitoring and reporting requirements also 

increased by 15% from 2005. The increase was due to the 

cyclical pattern of the monitoring requirements of the 

Chemical Contaminant Group. Small percentage 

decreases were seen in the violations of the Stage 1 

Disinfectants and Disinfection Byproducts Rule (DBPR), 

the Interim Enhanced Surface Water Treatment Rule, Lead 

& Copper Rule, and the Surface Water Treatment Rule. In 

2006, only 226 more violations of health-based standards 

were detected at public water systems and reported by 

states — a 1% increase from 2005. The total violations 

include health-based and significant monitoring and 

reporting violations, along with violations of the CCR and 

public notification. 

TCR and Chemical Violations 

In 2006, states reported the largest number of total 

violations (both health-based and significant monitoring 

and reporting) for the Chemical Group Rule. Typically the 

states report the most violations for either the Chemical 

Group Rule or the Total Coliform Rule. The cyclical 

pattern of the monitoring requirements for some rules in 

the Chemical Group can result in peaks and valleys in the 

number of violations. The 45,035 significant violations of 

monitoring and reporting requirements of the Chemical 

Group Rule represent 49% of all significant monitoring 

and reporting violations reported by the states in 2006. The 

2006 National Public Water Systems Compliance Report – National Summary Page 11 • March 2009 
highest number of health-based violations can be found in 

the Total Coliform Rule with 9,829 violations of the MCL 

representing 53% of all reported violations of health-based 

standards in 2006. Generally, the health-based violations 

are most frequently reported for the Total Coliform Rule. 

Implementation of Prior 

Year Recommendations 

EPA incorporated the following recommendations for 

fiscal years 2004, 2005, and 2006: 

States and EPA should continue working together to 

address significant violations of monitoring and 

reporting and notification requirements. 

States and EPA should continue working together to 

address violations of MCL and treatment technique 

requirements. 

EPA Regions continue to work with states to evaluate how 

well public water systems comply with the rules and 

whether enforcement actions are being initiated when 

appropriate. Regions and states have also identified and 

evaluated microbial risks to watersheds in an attempt to 

focus enforcement and compliance efforts on ensuring the 

safety of drinking water sources. Considerable effort has 

been devoted to training and compliance assistance. EPA 

works to build the capacity of small public water systems 

to maintain compliance both with established rules and 

with new microbial rules such as the Long Term 1 

Enhanced Surface Water Treatment Rule and the Ground 

Water Rule. In Indian country, where almost all public 

water systems are small, EPA continues to focus resources 

on ensuring compliance with the microbial rules and the 

standards for nitrates in drinking water through 

implementation of its new strategy for the FY05–07 Tribal 

National Compliance and Enforcement Priority. 

With respect to the rest of the drinking water program, 

states and EPA are continuing their efforts to implement 

the recommendations of the national public water system 

reports: 

•	 EPA provides funding to support eight technology 

assistance centers that help small systems with training, 

technical assistance, and technology demonstrations. 

•	 States and EPA help promote compliance with existing 

drinking water requirements by conducting numerous 

assistance activities, such as on-site visits and the 

distribution of easy-to-read guides and checklists. 

•	 EPA funding established and maintains the Local 

Government Environmental Assistance Network 

(LGEAN), a source of free information on current and 

developing SDWA requirements (as well as technical 

assistance, peer counseling, and financial guidance). 

LGEAN can be accessed on the Internet at 

www.lgean.org or by calling toll-free 1-877- TOLGEAN (865-4326). 

•	 EPA had established and maintains the Financing for 

Environmental Compliance website to provide financial 

and technical assistance resources to help communities 

create a plan to finance environmental capital assets. 

The Financing for Environmental Compliance can be 

accessed at 

http://www.epal.gov/compliance/assistance/financing/id 

ex.html 

•	 EPA has developed sets of tools that will assist small 

systems with implementing drinking water regulations 

and managing their systems while still providing 

adequate public health protection. The tools can be 

accessed on the Internet at 

http://www.epa.gov/safewater/cupss/index.html. 

•	 The states and EPA are pursuing enforcement actions 

against violating public water systems both to 

discourage violations and to ensure public health 

protection. 

Since September 1998, the findings and recommendations 

of the national public water systems reports have been 

incorporated into EPA’s ongoing efforts to ensure the 

reliability of data in SDWIS/FED. In its first national 

report, EPA noted that compliance data in many individual 

state reports differed from the data reported to 

SDWIS/FED. In 1998, EPA, states, and drinking water 

stakeholders agreed that our data quality goal should be 

“100% complete, accurate, and timely data submitted by 

public water systems and primacy agencies, consistent 

with SDWA reporting requirements.” Further analysis and 

discussions among the stakeholders led to establishment of 

interim milestones for how soon that goal will be achieved. 

EPA, states, and the drinking water stakeholders made 

significant progress on most of the data recommendations 

of the earlier national reports — in some instances 

achieving full implementation. Among the major 

accomplishments, EPA has: 

•	 improved the display of drinking water data in 

Envirofacts; 

• characterized and quantified the data quality problem; 

•	 taken interim steps to improve data quality, including 

improvements to the data entry tools states use to put 

information in SDWIS/FED and provision of a 

mechanism that enables water systems to confirm the 

accuracy of data before it is accepted by SDWIS/FED; 

and 

March 2009 • Page 12 2006 National Public Water Systems Compliance Report – National Summary 
•	 made a long-term commitment to achieve and maintain 

data quality goals. 

2006 Report Recommendations 

EPA, states, and drinking water stakeholders should 

continue to work cooperatively to improve the quality of 

the compliance data. More remains to be done to achieve 

the goal of 100% accurate, complete, and timely 

information. Some of the next steps EPA, states, and the 

drinking water stakeholders have agreed to undertake 

include: 

•	 streamlining data reporting and reducing rule 

complexity; 

•	 conducting more training to ensure regulatory staff can 

accurately determine compliance with drinking water 

rules and data entry staff can upload complete and 

accurate data to SDWIS/FED; 

•	 encouraging states to issue annual reminders to water 

systems of their compliance monitoring schedules; 

•	 providing states with individual, prioritized 

recommendations for improving their data quality; 

• performing more frequent data verification audits; 

•	 calculating estimates for SDWIS/FED data quality every 

three years, or more frequently if data from a sufficient 

number of data verifications are available; 

•	 working with the Association of State Drinking Water 

Administrators (ASDWA) to implement its updated 

2006 Data Reliability Analysis and Action Plan 

(DRAAP) http://www.epa.gov/compliance/resources/ 

reports/accomplishments/sdwa/sdwacom2005.pdf; 

•	 negotiating grant conditions with several states to 

encourage them to follow quality assurance/quality 

control plans for drinking water violation data reported 

to EPA and address the differences in interpretation of 

the regulation; and 

•	 working with all states to implement the EPA Order 

5360.1 A2 dealing with requirements for quality 

management systems. 

2006 National Public Water Systems Compliance Report – National Summary Page 13 • March 2009 
National Summary of Compliance for Public 

Water Systems in Indian Country in 2006 

INTRODUCTION 

This section of the 2006 National Public Water Systems 

Compliance Report describes how the Environmental 

Protection Agency (EPA) and federally-recognized Indian 

tribes (tribes) are meeting the goal of ensuring that public 

water systems in Indian country provide safe drinking 

water. 

PUBLIC WATER SYSTEMS IN 

INDIAN COUNTRY 

Tribes may apply for eligibility to receive primary 

enforcement authority (known as primacy) to administer 

the drinking water program provided they meet the 

requirements of Sections 1413 and 1451 of the Safe 

Drinking Water Act (SDWA). As of 2006, only the Navajo 

Nation had received primacy for most public water 

systems on the Navajo Reservation. EPA administers the 

drinking water program in the rest of Indian country. 

A glossary of terms used in this report appears in 

Appendix A. A map of the areas covered by this section 

appears in Appendix C. 

PUBLIC WATER SYSTEMS IN 

ALASKA AND OKLAHOMA 

Compliance figures for Alaska Native Villages outside of 

Indian country are not included in this section of the 

report. Similarly, compliance figures for 18 public water 

systems in Indian country located in Oklahoma are not 

included in this section of the report. The Alaska Native 

Villages and these 18 systems in Oklahoma are not 

federally recognized tribes, therefore, the state acts as the 

primacy agency in reports violations. In both cases, this 

information is found in the state reports for Alaska and 

Oklahoma, respectively. The state reports do not, however, 

contain separate information on these public water 

systems. 

DATA QUALITY 

This report uses information from the Safe Drinking Water 

Information System/Federal Version (SDWIS/FED). 

SDWIS/FED is the national database where EPA records 

information on public water systems in Indian country. 

Public water systems in Indian country are required to 

report laboratory data to EPA. EPA uses the information to 

determine compliance with the national primary drinking 

water regulations of SDWA. 

This report also discusses the limitations in the data EPA 

uses to measure its success and the steps it is taking to 

increase data reliability and completeness. In addition, the 

report also discusses EPA’s compliance assistance, 

enforcement, and financial assistance programs. EPA plans 

to continue its data quality efforts to ensure that 

SDWIS/FED contains complete and accurate information. 

A complete discussion of data quality is in the National 

Summary of Public Water Systems Compliance under the 

section entitled Data Quality.

by non-community water systems. 

COMPLIANCE ASSISTANCE 

AND ENFORCEMENT 

EPA uses multiple approaches to ensure public water 

systems in Indian country comply with SDWA regulations. 

EPA’s tribal compliance assistance program is designed to 

help maintain compliance with SDWA by building 

cooperative working relationships with utility managers, 

operators, other tribal environmental staff, and tribal 

elected officials. The program emphasizes information 

exchanges, operation assistance, and water quality 

monitoring. 

EPA provides compliance assistance to system operators, 

utility managers, and owners through training sessions, 

newsletters, telephone support, and system visits. 

Engineers and qualified staff provide on-site assistance to 

assess current compliance status, develop monitoring 

schedules and compliance plans, and conduct sanitary 

March 2009 • Page 16 2006 National Public Water Systems Compliance Report – Section on Indian Country 
surveys. EPA coordinates many of these activities with 

other federal agencies, including the Indian Health Service 

and the Bureau of Reclamation. Coordination also occurs 

with non-governmental organizations and inter-tribal 

consortia, including the Native American Water 

Association, the Rural Water Association, and the Rural 

Community Assistance Corporation. 

In federal fiscal year 2006, EPA’s Office of Enforcement 

and Compliance Assurance continued to focus increased 

attention on environmental issues in Indian country 

through implementation of the National Indian Country 

Enforcement and Compliance Assurance Priority. One of 

the goals was to improve compliance with drinking water 

standards by the end of fiscal year 2010. Under this 

national effort, EPA worked to improve the quality of 

public water system data, provide additional compliance 

assistance, and reduce the number of systems that are out 

of compliance with key health-based standards. 

In 2006, public water systems were required to monitor for 

89 different contaminants and conduct analyses using a 

variety of EPA-approved analytical methods. Where a 

system fails to perform monitoring for some or all of the 

required contaminants, a separate monitoring and reporting 

violation is recorded for each missed contaminant. Each of 

these violations is enforceable. 

EPA is also responsible for initiating enforcement actions 

against owners or operators of public water systems in 

Indian country if a system is not in compliance with 

SDWA. In most cases, EPA relies on compliance 

assistance and informal enforcement actions to facilitate a 

tribally-owned or -managed public water system's return to 

compliance. When a formal enforcement action is 

appropriate, EPA can initiate administrative orders, 

including emergency administrative orders, and refer civil 

and criminal cases to the Department of Justice. The "EPA 

Policy for the Administration of Environmental Programs 

on Indian Reservations" (EPA Indian Policy, 11/8/84) and 

the "Guidance on the Enforcement Principles Outlined in 

the 1984 Indian Policy" (EPA Tribal Enforcement 

Principles) guide the Agency's approach to bringing civil 

administrative or judicial enforcement actions against 

systems in Indian country. During 2006, EPA issued one 

federal administrative order in Indian country. This does 

not include informal enforcement actions (i.e. warning 

letters, notices of violation), compliance assistance 

activities, or the public water systems that returned to 

compliance before EPA procedures would require 

initiation of a formal response. 

EPA generally designates a public water system to be in 

significant non-compliance (SNC) if the system has 

serious, frequent or persistent violations for a specific 

regulation that may pose a threat to public health. This 

enables the states and EPA to prioritize enforcement 

resources to ensure that the most severe violations are 

addressed first. In EPA’s “timely and appropriate” 

guidance for drinking water, violations that have been 

elevated to the SNC level are to be addressed with a formal 

enforcement action within six months of receiving the 

SNC designation. EPA reviews the state-reported 

violations quarterly to identify new systems as being in 

SNC for one or more rules or other systems as being 

addressed SNCs. In determining the total number of 

systems that are in significant non-compliance, EPA does 

not take into account the public water systems that have 

returned to compliance due to informal enforcement 

actions or compliance assistance, or public water systems 

that have returned to compliance before EPA and the states 

have initiated a formal response. 

•	 Of the 817 public water systems in Indian country, EPA 

determined that 292 systems were in significant 

noncompliance with one or more drinking water 

standards in calendar year 2006. Over 90% of these 

systems are small systems serving 3,300 or fewer users. 

•	 In 2006 states and EPA addressed non-compliance at 

100 public water systems. Additionally the states and 

EPA addressed 68 of the systems with SNC outside of 

the 2006 calendar year, leaving 124 systems (over 15% 

of the systems in Indian country) with unaddressed 

SNCs. 

A system can be designated as SNC if it has a poor 

monitoring & reporting history, although it doesn’t have a 

health-based violation. For the systems designated as SNC 

in 2006 less than 60 had health-based violations. 

FINANCIAL ASSISTANCE 

EPA provides financial assistance to public water systems 

in Indian country to help build tribal capacity to operate 

and maintain systems in compliance with SDWA. 

Capacity building is a long-term solution which focuses on 

providing grants to tribes and providing training, and 

technical assistance as they develop their environmental 

programs. EPA’s Indian General Assistance Program 

builds tribal capacity by providing grants to plan, develop, 

and establish environmental protection programs, 

including drinking water programs. 

EPA also distributes funds for specific drinking water 

program priorities. EPA set aside $6,325,400 in FY2006 

for activities to support Tribal Public Water System 

Supervision (PWSS) Programs. EPA uses these funds to 

operate the PWSS program in Indian country. Tribes with 

primacy for the drinking water program also receive 

financial support from PWSS funds. Currently, the Navajo 

2006 National Public Water Systems Compliance Report – Section on Indian Country	 Page 17 • March 20009 
Nation is the only tribe with primacy for the drinking 

water program. These funds are used to implement the 

PWSS program, including activities such as: 

•	 Improving capacity at tribal drinking water systems 

source water and wellhead protection projects; 

• Completing Source Water Assessments; 

• Providing training to tribal operators; 

• Compiling and analyzing compliance information; and 

• Responding to violations. 

In the 1996 Amendments to SDWA, an infrastructure 

funding program was established to improve water 

supplies. Each year, 1.5% of the appropriation for the 

national Drinking Water State Revolving Fund program is 

set aside for American Indian communities and Alaska 

Native Villages. The FY 2006 set-aside amounted to 

$12,562,400. These funds are used to improve the 

infrastructure of water systems serving tribal populations 

to achieve compliance with drinking water standards. This 

includes projects such as: 

• distribution system improvements; 

• community water system extensions; 

• replacement of water mains; 

• adding new wells; 

• treatment improvements; 

• construction of new pumphouses; and 

• consolidation of PWS. 

Finally, technical assistance and training for small tribally 

owned or operated public water systems are also provided. 

Through the cooperative agreements, small tribal public 

water systems receive information on training and 

technical assistance, wellhead and ground water 

protection, and source water protection. 

CONCLUSIONS AND 

RECOMMENDATIONS 

In 2006, EPA Regions reported that 39% of the public 

water systems in Indian country did not report a violation 

of a health-based standard, a significant monitoring and 

reporting violation, or a significant consumer notification 

violation. This represents an 8% improvement from 2005. 

During 2006, there was a decrease in the total number of 

significant violations of monitoring and reporting 

requirements in Indian country (decreased from 1,223 in 

2005 to 1,076 in 2006). 

EPA continues to implement two primary 

recommendations from previous reports: (1) improve 

collection and maintenance of compliance data for public 

water systems in Indian country; and (2) place a priority on 

decreasing the number of monitoring and reporting 

violations to gain a full understanding of whether healthbased violations exist. EPA is accomplishing these 

recommendations by: 

•	 improving the inventory of public water systems in 

Indian country; 

•	 focusing on the collection and entry into SDWIS/FED of 

compliance and enforcement; 

•	 continuing to work with tribal governments, utility 

managers, and water system operators to improve 

compliance with monitoring and reporting requirements 

and with health-based standards, particularly the Total 

Coliform Rule and Surface Water Treatment Rule; 

•	 in Indian country, where almost all public water systems 

are small, EPA will continue to focus resources on 

ensuring compliance with the microbial rules and the 

standards for nitrates in drinking water through 

implementation of the National Indian Country 

Enforcement and Compliance Assurance Priority; 

•	 maintaining EPA’s direct on-site compliance assistance, 

including conducting frequent sanitary surveys and 

targeting systems with repeat violations; and 

•	 continuing to support and encourage capital 

improvements for public water systems to improve the 

infrastructure (and therefore compliance with SDWA 

requirements) of public water systems in Indian country, 

including grants provided under the Drinking Water 

Tribal Infrastructure Grant Tribal Set-Aside Program. 

Ultimately, EPA continues to respond to compliance and 

enforcement issues at public water systems owned, 

operated, or managed by tribal governments in a manner 

consistent with SDWA, the EPA Indian Policy, and the 

EPA Tribal Enforcement Principles. Where compliance 

assistance is ineffective or where, among other things, 

there is a significant threat to human health or the 

environment, EPA takes appropriate steps to return 

systems to compliance, including formal enforcement 

actions. 

March 2009 • Page 18 2006 National Public Water Systems Compliance Report – Section on Indian Country 
Appendix A 

Glossary of Terms 
Administrative Order 

Formal enforcement actions issued by EPA or a State to 

address noncompliance at a public water system, usually 

by means of a compliance schedule with enforceable 

milestone dates. 

Chemical Rules 

Refers collectively to regulations that protect the public 

from unsafe levels of organic chemicals, inorganic 

chemicals (including lead and copper), and radioactivity in 

drinking water. 

Community Water System 

A public water system that serves at least 15 service 

connections used by year-round residents or regularly 

serves at least 25 year-round residents (e.g., homes, 

apartments and condominiums that are occupied yearround as primary residences). 

Consumer Confidence Rule (CCR) 

Requires community water systems to prepare and provide 

to their customers annual consumer confidence reports on 

the quality of the water delivered by the systems. 

Disinfection/Disinfectant 

By Product Rule (DBPR) 

Applies to community water systems and nontransient 

non-community systems, including those serving fewer 

than 10,000 people, that add a disinfectant to the drinking 

water during any part of the treatment process. The Stage 1 

DBPR specifically addresses risks associated with 

disinfectants and disinfectant byproducts. This rule was 

published concurrently with the Interim Enhanced Surface 

Water Treatment Rule (IESWTR), which addresses control 

of microbial pathogens. 

Federally-recognized Indian Tribe 

An Indian tribe, band, nation, pueblo, community, or 

Alaska Native Village that the Secretary of the Interior 

acknowledges to exist as an Indian tribe pursuant to the 

Federally Recognized Indian Tribe List Act of 1994, 25 

U.S.C. Section 479a. Maintained by the Department of the 

Interior, the list of federally-recognized tribes is updated 

periodically and published in the Federal Register. The 

latest list of federally-recognized Indian tribes is available 

at 65 Federal Register 12398 (March 13, 2000). 

Filter Backwash Recycle Rule (FBRR) 

Requires public water systems (PWSs) to review their 

backwash water recycling practices to ensure that they do 

not compromise microbial control. Under the FBRR, 

recycled filter backwash water, sludge thickener 

supernatant, and liquids from dewatering processes must 

be returned to a location such that all processes of a 

system's conventional or direct filtration including 

coagulation, flocculation, sedimentation (conventional 

filtration only) and filtration, are employed. Systems may 

apply to the State for approval to recycle at an alternate 

location. The Filter Backwash Rule applies to all public 

water systems, regardless of size. 

Health-based Violation 

A violation of either a Maximum Contaminant Level or a 

Treatment Technique requirement. 

Inorganic Chemicals 

These non-carbon based compounds (such as metals, 

nitrates, and asbestos) can either occur naturally in some 

sources of drinking water or be introduced by human 

activity. EPA has established MCLs for 15 inorganic 

contaminants. Violations of standards for lead and copper 

are addressed separately. 

Interim Enhanced Surface Water Treatment 

Rule (IESWTR) 

Applies to systems using surface water, or ground water 

under the direct influence of surface water, that serve 

10,000 or more persons. The rule also includes provisions 

for states to conduct sanitary surveys for surface water 

systems regardless of system size. 

Large System 

A public water system that serves more than 10,000 

people. 

Lead and Copper Rule (LCR) 

Requires a public water system to take steps to minimize 

the risk of exposure to lead and copper in drinking water 

by monitoring for these contaminants, installing corrosion 

control where required, and, where necessary, educating 

the public about ways to reduce exposure. A system may 

also be required to treat its source water or replace lead 

service lines. 

2006 National Public Water Systems Compliance Report – Appendix A Page A-1 • March 2009 
Maximum Contaminant Level 

The maximum permissible level of a contaminant in water 

Maximum Disinfectant 

Residual Level (MDRL) 

A level of a disinfectant added for water treatment that 

may not be exceeded at the consumer's tap without an 

unacceptable possibility of adverse health effect. 

Monitoring and Reporting Violation 

Refers to either a violation of a monitoring and reporting 

schedule or violation of contaminant-specific minimum 

testing schedules and operational reporting requirements. 

Those monitoring and reporting violations considered 

“significant” for the purposes of the state and national 

public water system compliance reports are described 

below in Table A–1. 

Nitrate and Nitrite 

Inorganic compounds that can enter water supplies, 

primarily from fertilizer runoff, livestock farms, and 

sanitary wastewater discharges. 

Non-transient Non-community Water System 

A non-community public water system that regularly 

serves at least 25 of the same persons over six months per 

year. A typical example of a non-transient non-community 

water system is a school or an office building that has its 

own water source, such as a drinking water well. 

Organic Chemicals 

These carbon-based compounds, such as solvents and 

pesticides, can enter drinking water through a variety of 

means, including factory discharges or runoff from crop 

lands. EPA has established MCLs for 56 organic 

contaminants. 

Primacy 

The Safe Drinking Water Act requires EPA, States, and 

Tribes to work as partners to ensure delivery of safe 

drinking water to the public. Any State or Indian Tribe can 

request responsibility for operation and oversight of the 

drinking water program within its borders. In order to 

receive this responsibility (called “primary enforcement 

authority” or “primacy”), a State or Tribe must show that, 

among other things, it has adopted drinking water 

regulations that are at least as stringent as Federal 

regulations, and demonstrate its capacity both to enforce 

those regulations and to implement other activities 

necessary to ensure compliance. 

delivered to any user of a public water system. 

In the absence of State or Tribal primacy, EPA assumes 

responsibility for administering the drinking water 

program for that area. Of the 56 eligible States (defined to 

include Commonwealths, Territories, and the District of 

Columbia), all but Wyoming and the District of Columbia 

have primacy. During calendar year 2001, the EPA 

Regional Offices administered the drinking water program 

within these two jurisdictions and on all Tribal lands, 

except for the Navajo Nation. 

Primary Drinking Water Regulations 

These are regulations that apply to public water systems; 

specify contaminants which, in the judgment of the 

Administrator, may have an adverse effect on the health of 

persons; and specify for each such contaminant either a 

maximum contaminant level or a treatment technique. 

Public Water System (PWS) 

A system for the provision to the public of water for 

human consumption through pipes or other constructed 

conveyances, if such system has at least 15 service 

connections or regularly serves at least 25 individuals at 

least 60 days out of the year. A public water system can be 

either a community water system, a non-transient 

noncommunity water system, or a transient noncommunity 

water system. 

Radionuclides 

Radioactive particles, such as radium-226, radium-228, 

gross alpha, and beta particle/photon radioactivity, can 

occur naturally in water or may result from human activity. 

EPA has established MCLs for uranium, beta/photon 

emitters, alpha emitters, and combined radium 226/228. 

Regional Offices 

Responsible for implementing Environmental Protection 

Agency programs within their respective jurisdictions. 

Regional Offices cooperate with Federal, State, interstate, 

and local agencies, as well as with industry, academic 

institutions, and other private groups to ensure that 

Regional needs are addressed and that Federal 

environmental laws are upheld. 

Small Systems 

Public water systems that serve no more than 3,300 people. 

Page A-2 • March 2009 2006 National Public Water Systems Compliance Report – Appendix A 
Surface Water Treatment Rule (SWTR) 

The Surface Water Treatment Rule requires a public water 

system served by surface water or by ground water under 

the influence of surface water to take steps (such as 

disinfection, filtration followed by disinfection, or 

watershed control) to reduce potential exposure to 

microbiological contamination. 

Total Coliform Rule (TCR) 

Establishes limits on coliform bacteria in water distribution 

systems. Although coliform bacteria, which are found in 

decaying organic material and in the intestinal tract of 

humans and animals, are usually not harmful to human 

health, their presence may indicate the presence of other, 

more dangerous microbial contamination. 

SDWIS/FED 

EPA’s database for collecting safe drinking water 

monitoring results from oversight agencies. SDWIS stands 

for Safe Drinking Water Information System. Public Water 

Systems are required to report all monitoring results to the 

primary enforcement authority. States with primacy, or 

EPA where it administers the program, analyze the 

monitoring results, determine compliance, and report 

violations to EPA on a quarterly basis. EPA maintains 

records of these violations in SDWIS/FED. SDWIS/FED 

records only violations, not results that demonstrate 

compliance with drinking water standards. 

Total Trihalomethanes 

These chemicals can be by-products of chemical processes 

used to disinfect drinking water. 

Transient Non-community Water System 

A non-community water system that regularly serves at 

least 25 people (but not the same 25) over six months per 

year. A typical example is a campground or a highway rest 

stop that has its own water source, such as a drinking water 

well. 

Treatment Technique 

In cases where EPA has determined it is not technically or 

economically feasible to establish an MCL, the Agency 

can instead specify a treatment technique. These are 

treatment methods required by EPA to minimize the level 

of a contaminant in drinking water. 

Variances and Exemptions 

A public water system that cannot comply with a drinking 

water standard because of poor source water quality, or, in 

the case of small systems, inadequate financial resources, 

can be granted a variance to comply with less stringent, but 

still protective standards based on a specific EPAapproved technology available to the system. An 

exemption allows a PWS with compelling circumstances 

(including economic considerations) additional time to 

achieve compliance with applicable SDWA requirements, 

so long as public health is adequately protected.

Page B-1 March 2009 2006 National Public Water Systems Compliance Report – Appendix B 
__________ 

This Appendix presents a summary of each state report in 

a standardized format. The format includes an overall 

summary of the violations data specified in Section 1414 

of the 1996 Safe Drinking Water Act (SDWA) 

Amendments (i.e., violations with respect to maximum 

contaminant levels (MCLs), treatment technique 

violations, significant monitoring and reporting 

requirements, significant notification violations, and 

variances and exemptions). 

This Appendix summarizes the data reported by the 

States, but does not interpret it. Therefore, other factors 

must be taken into account before drawing conclusions 

about a State program. For example, public water 

systems are required to report all violations to the State, 

but State drinking water programs vary in the 

regulations they choose to emphasize. A State that 

decided to focus attention and resources on one 

particular rule may have discovered and reported many 

more violations of that rule than a State that chose to 

focus on a different rule. A disproportionate number of 

violations in a State could also indicate that the State 

needs to work with its public water systems to improve 

their compliance. Readers are cautioned to view the 

violations data provided in the State summaries within 

the context of each State and its individual drinking 

water program. 

In 2006, EPA received State Public Water System 

Compliance Reports from 45 of the 57 primacy states, 

Commonwealths, Territories, and tribes. As in past years, 

American Samoa, Guam, and the Northern Mariana 

Islands did not submit reports, and, with limited 

exceptions, did not supply information to SDWIS/FED. 

EPA did not receive a report from Arizona, Indiana, 

Massachusetts, New Jersey, Oregon, the Virgin Islands, 

and Vermont. Appendix B supplies what information is 

available in SDWIS/FED to indicate violations at public 

water systems in the Pacific territories. Because the 

District of Columbia, Wyoming, and most Indian Tribes 

did not have primary enforcement responsibility for 

drinking water in calendar year 2006, EPA prepared 

reports for those jurisdictions. 

A comprehensive definition of significant monitoring and reporting 

violations including exceptions to the definition for the Total Coliform 

Rule and Lead and Copper Rule appears in Appendix A. 

Violations for 2006 

EPA summarizes the number of MCL/MDRL, treatment 

technique, and significant monitoring and reporting 

violations1 reported by each state in six categories: 

•	 Violations of chemical contaminant requirements2 

•	 Violations of the Total Coliform Rule 

•	 Violations of the Surface Water Treatment Rule, 

Surface Water Treatment Rule, Interim Enhanced 

Surface Water Treatment Rule, Long Term 

Enhanced Surface Water Treatment Rule, and 

Filter Backwash Recycling Rule 

•	 Violations of the Lead and Copper Rule 

•	 Significant Notification or Consumer Confidence 

Rule Violation 

•	 Violations of the Disinfection/Disinfectant 

Byproducts Rule 

EPA summarizes the numbers of individual public water 

systems in violation in each of these five categories, as 

reported by the state. If a state’s report did not include 

information in a category, EPA’s summary notes the 

omission. 

2006 Totals 

EPA also summarizes the total number of systems in each 

state, the total number of significant violations reported, 

and the total number of PWSs in violation, if the state 

reported this information. When states did not provide 

information on the total number of public water systems, 

EPA supplied that information from the SDWIS/FED. 

Systems in Violation 

Systems in Violation is defined as the number of different 

systems with a reported violation of this type. Some states 

counted a system with multiple violations or violations in 

more than one category as one violating system. Other 

states counted a violating 

2 

MCL and significant monitoring violations for organic, inorganic, total 

trihalomethane (TTHM), nitrate and nitrite, and radionuclide 

contaminants. 

Page B-2 March 2009	 2006 National Public Water Systems Compliance Report – Appendix B 
system each time it had a violation, or once for each of the 

regulatory categories in which it had a violation. If EPA’s 

review of a state’s report indicated some violating systems 

were counted more than once, an asterisk notes that the 

state’s number possibly overcounts violating systems 

Variances and Exemptions 

No states reported a violation of a variance or exemption 

in 2006. 

Where to Obtain the 2006 Annual Public 

Water Systems Report 

If a state’s report includes information on how to obtain a 

copy of the report, that information is provided on the state 

summary page in this Appendix.
