National Summary of 

Public Water Systems Compliance in 2004 

INTRODUCTION 

The National Public Water Systems Compliance 

Report for 2004 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. 

Some 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 2004 94% of America’s public water systems 

reported no violations of a health-based drinking 

water standard. 

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. 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 year-round residences or regularly 

serve at least 25 year-round 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 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 report is an annual 

summary of reported violations at the nation’s public 

water systems. This report also 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 the public water system compliance using data 

from the Safe Drinking Water Information 

System/Federal Version (SDWIS). SDWIS is the 

national database where states and tribes with 

primacy report annually to EPA violations of the 

maximum contaminant levels, treatment techniques, 

significant monitoring and reporting, significant 

consumer notification, 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 2004 

are presented in Appendix B. 

1 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 2004, 

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) provides customers 

with a more complete picture of drinking water quality 

and systems operations. The annual 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 their customers the report. 

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/pn/rulefact.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 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 

monitoring and reporting violations, only significant” 

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. 

December 2006 • Page 2 2004 National Public Water Systems Compliance Report – National Summary 
__________ 

• A significant user notification violation occurs when 

a community water system completely failed 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 should not be the 

primary notification of potential health risk posed by 

drinking water, but 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. 

EPA routinely evaluates state programs by 

conducting data verification audits and triennial 

national summary evaluations. These triennial 

reviews revealed that only 65% of the apparent MCL 

violations and 23% of the apparent monitoring and 

reporting violations had been reported to 

SDWIS/FED (although what percent of the 

unreported monitoring and reporting violations are 

significant violations is unknown). Since the reviews, 

EPA and its state partners 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 

In 2004, 158,802 public water systems together 

served over 296 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.

• 52,537 community water systems served more 

than 272 million people in their primary residences. 

• 19,258 non-transient non-community systems (i.e., 

schools, factories) served almost 6 million people 

in places they frequented. 

• 87,007 transient non-community systems (i.e., 

campgrounds, highway rest stops) served a 

constantly changing user base of over 18 million 

people. 

Most public water systems were small, but large 

systems served a majority of the people who 

drank water from a public water system.

served 3,300 or fewer users. Together, these 

149,946 small systems provided service to only 

14% of all users. 

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.

• 2% of America’s public water systems served more 

than 10,000 users. Together, these 3,956 large 

systems provided service to 77% of all users. 

Overall Compliance Picture 

Most Americans received drinking water from 

public water systems that recorded no significant 

violations in 2004.

No Violation 

For 74% of the public water systems in America, 

there was no report of a health-based violation nor 

were there reports of significant monitoring and 

reporting violations. The primacy states reported 

either a health-based violation, a significant 

monitoring and reporting violation, or a significant 

CCR violation at 41,310 public water systems in 

2004.

76% of the population served by public water 

systems received drinking water from a system that 

reported no violations of a health-based standard, 

was not cited for a significant violation of a monitoring 

and reporting requirement, and issued a consumer 

confidence report, if required. 

• There were 10,161 reported violations of the CCR 

Rule in 2004. 

One violation of a variance or exemption was 

reported to SDWIS/FED during 2004. 

• 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 

2004, only one state (New York) reported a 

violation of the variance or exemption. 

Health-Based Drinking Water Standards 

94% of America’s public water systems, serving 

92% of the users, did not report any violations of 

health-based drinking water standards in 2004. 

PWS with No Reported Health-Based Violations

The Maximum Contaminant Level for the Total

most frequently violated. SDWIS/FED recorded 

15,173 violations of health-based standards in 2004. 

Sixty-three percent (63%) 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 

The health-based standard that was reported with the 

least number of violations was the Interim Enhanced 

Surface Water Treatment Rule (IESWTR) with just 

over a hundred violations. Only the largest public 

water systems are subject to the IESWTR.

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

is impossible to know if it has violated a healthbased requirement. For this reason, a system’s 

significant failure to monitor and report is a major 

violation that must be addressed and corrected. 

• 52% of the 106,412 significant monitoring and 

reporting violations reported by the states were 

violations of the requirements of the Chemical 

Contaminant Group. In 2004 the states reported 

more than twice as many Chemical Contaminant 

Group monitoring and reporting violations as in 

2003. 

• 29% of the 106,412 significant monitoring and 

reporting violations reported by the states were 

violations of the requirements of the TCR. The 

states reported 8% fewer TCR monitoring and 

reporting violations than the previous year.

Drinking Water Standards 

Approximately four-fifths of the 132,573 violations the 

states reported to SDWIS/FED in 2004 were for a 

public water system’s significant failure to monitor 

and report, rather than a violation of a standard. 

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 (TCR); 3) lead and copper (LCR); 4) surface water treatment (SWTR) Interim Enhanced Surface Water 

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

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. 

2004 National Public Water Systems Compliance Report – National Summary Page 5 • December 2006 
Does a Health-Based Violation Mean Drinking the Water Causes Illness? 

It is important to note that a public water system’s 

violation of a health-based standard does not mean 

that the people who drank the system’s water got sick. 

A health-based violation means either that the system 

has exposed its users to what EPA has judged as an 

unreasonable risk of illness, or that the system has 

failed to treat its water to the extent EPA has judged 

necessary to protect its users from an unreasonable 

risk of illness in the event that the regulated 

contaminant is present in source water. Many variables 

affect the likelihood of illness resulting from healthbased violations, among them the duration of the 

violation, whether or not the violation occurred in an 

isolated section of a complex public water system, and 

the extent to which contamination exceeds the 

allowable level. 

While modern treatment systems have substantially 

reduced the incidence of waterborne disease, drinking 

water contamination remains a significant health risk 

management challenge. Studies by the Centers for 

Disease Control (CDC) indicate that between 1980 and 

1998 there were 419 outbreaks of illness linked to 

contamination in drinking water resulting in an 

estimated 511,000 cases of disease (Craun and 

Calderon, 1996; Levy et al., 1998; Barwick et al., 2000). 

The majority of outbreaks in the U.S. occurred at 

surface water systems. Nearly 80% of all reported 

cases of illness were associated with the 1993 

Cryptosporidium outbreak in Milwaukee, WI, which 

resulted in an estimated 403,000 cases (MacKenzie et 

al. 1994; McDonald et al. 2001). 

The number of waterborne disease outbreaks identified 

and reported in the CDC database is believed, 

however, to understate the actual incidence of 

outbreaks and cases of illness (Craun and Calderon, 

1996; National Research Council, 1997). The most 

recent CDC report on outbreak data for 2001–2002 is 

available at 

http:www.cdc.gov/mmwr/PDF/SS/SS5308.pdf. 

Recognized and reported waterborne disease 

outbreaks are usually the result of exposure to 

waterborne pathogens that cause acute gastrointestinal 

illness with diarrhea, abdominal discomfort, nausea, 

and vomiting. Because such illnesses are generally of 

short duration in healthy people, many individuals 

experiencing these symptoms do not seek medical 

attention. Where medical attention is sought, the 

pathogenic agent may not be identified through routine 

testing. Consequently, outbreaks are often not 

recognized in a community or, if recognized, are not 

traced to a drinking water source. Moreover, an 

unknown but probably significant portion of waterborne 

disease is endemic (i.e., isolated cases not associated 

with an outbreak) and, thus, is even more difficult to 

recognize. Waterborne disease information does not 

include information on diseases that would be caused 

by contaminants with chronic effects. 

EPA’s health-based standards are intended to provide 

an adequate margin of safety not just for healthy 

people, but also for populations that are at greater risk 

from waterborne disease. These sensitive 

subpopulations include children (especially the very 

young), the elderly, the malnourished, pregnant 

women, the disease-impaired (e.g., those with 

diabetes, cystic fibrosis), and a broad category of those 

with compromised immune systems, such as AIDS 

patients, those with autoimmune disorders (e.g., 

rheumatoid arthritis, lupus erythematosus, multiple 

sclerosis), transplant recipients, and those on 

chemotherapy (Rose, 1997). Immunocompromised 

persons are more likely than healthy individuals to 

contract waterborne disease, the severity and duration 

of their illness is often greater, and they are at a greater 

risk of death. 

December 2006 • Page 6 2004 National Public Water Systems Compliance Report – National Summary 
Community Water Systems 

Although community water systems make up only 

one-third of the public water systems in America, they 

serve 92% of population served by public water 

systems. 

• 75% of the population served by community water 

systems received drinking water from a system that 

reported no violations of a health-based standard, 

was not cited for a significant violation of a 

monitoring and reporting requirement, and issued a 

consumer confidence report as required. 

• About 18,700 (36%) out of the over 52,000 

community water systems had significant 

violations. Of the 272 million users served in their 

primary residence by community water systems, 

approximately 69 million (25%) received their water 

from one of the violating community water systems. 

• Approximately 2,100 (25%) of the more than 8,600 

larger community water systems serving more than 

3,300 users had significant violations. These 

violating larger community systems served more 

than 61 million (22%) of the 272 million users 

served in their primary residence by community 

water systems. 

• Of the approximately 44,000 small community 

water systems serving 3,300 users or less in their 

primary residence, over 16,600 (38%) had 

significant violations. Over 7.8 million (3%) users 

were served by these small community water 

systems. 

• The Consumer Confidence Report (CCR) Rule 

requires all community water systems to provide an 

annual report to customers identifying the 

contaminants detected in their water and the health 

risks associated with those contaminants. As 

reported to SDWIS/FED, 87% of community 

water systems complied with the CCR Rule. 

Non-Community Water Systems 

• Approximately 22,500 (21%) out of over 106,000 

non-community water systems had significant 

violations. The vast majority of these were small 

non-community water systems serving 3,300 users 

or less. Together these small systems with 

significant violations served only 3.2 million (13%) 

users out of the approximately 24 million users 

served by non-community water systems. 

• 52 (21%) out of 248 larger non-community water 

systems serving more than 3,300 users had 

significant violations. Together these 52 larger noncommunity systems served only about 464,000 

(1.9%) users of the approximately 24 million users 

served by non-community water systems. 

HOW DOES EPA HELP PWS 

COMPLY WITH REQUIREMENTS? 

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. 

2004 National Public Water Systems Compliance Report – National Summary Page 7 • December 2006 
__________ 

What Happens to Systems in Violation of 

the Requirements? 

When a drinking water violation is detected and it is 

determined that compliance assistance is not the 

best tool to return a source to compliance, EPA 

guidelines require a response from the primacy 

agency as a condition of funding. Acceptable 

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 such as: 

• compliance assistance as appropriate; 

• 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 will 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 2004, EPA and its state partners initiated 

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. Together, EPA 

and the states initiated 4,478 formal enforcement 

actions, each action potentially addressing multiple 

violations.5 

• In 2004 the states issued a total of 3,959 formal 

enforcement actions, including 1,351 administrative 

orders without penalty, 869 administrative orders 

with penalty, 45 civil referrals to the states’ 

Attorneys General, 824 signed State Bilateral 

Compliance Agreements (BCA), 860 state 

intentional no-actions, and ten civil cases filed. 

• During the same period, EPA issued a total of 519 

formal enforcement actions, including 221 Federal 

administrative orders, 3 Federal Emergency 

Orders, 116 Federal No longer subject to rule, 177 

Federal Intentional no actions, and two signed 

Federal BCA. 

These totals do not take into account 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 designates a public water system a significant 

noncomplier if the system has serious, frequent or 

persistent violations that may pose a threat to public 

health. States and EPA give significant noncompliers 

priority attention in their efforts to return violators to 

compliance and address violations with enforcement 

actions. 

• In calendar year 2004, EPA designated 16,668 

public water systems significant noncompliers, 

which was comparable to the number of public 

water systems designated as significant 

noncompliers in 2002 and 2003. Over 90% of 

these significant noncompliers in all these years 

served 3,300 or fewer users. 

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. 

December 2006 • Page 8 2004 National Public Water Systems Compliance Report – National Summary 
• In 2004 states and EPA addressed 4,392 

significant noncompliers. Of the noncompliers 

addressed, 1,563 (36%) were new significant 

noncompliers identified in 2004. The other 2,829 

were systems addressed as significant 

noncompliers in 2003 and earlier. 

• The totals for significant noncompliers addressed 

do not take into account public water systems that 

are no longer significant noncompliers because of 

informal enforcement actions or compliance 

assistance, or public water systems that returned to 

compliance before EPA and state procedures 

would require initiation of a formal response. 

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 most recent 

(1999–2001) audits, which covered 31 states, 

analyzed data from 1,890 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 

improving, but the data are incomplete. This finding 

principally reflects differences between state and 

EPA regulatory interpretation 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: 

• 95% of all inventory data in SDWIS/FED was 

accurate and complete. 

• The overall quality of SDWIS/FED violations data 

improved from the first assessment to the second 

from 68% to 75% for the Total Coliform Rule 

standard, but other violations related to healthbased standards and monitoring and reporting are 

not as high. 

• Most of the discrepancies between apparent and 

reported violations are because of unrecorded and 

unreported violations. This accounts for 62% of all 

discrepancies related to maximum contaminant 

level/treatment technique violations and 86% of all 

discrepancies related to monitoring and reporting 

violations. 

• Only 27% of apparent monitoring and reporting 

violations had been reported to SDWIS/FED. 

• 65% of the apparent MCL/treatment technique 

violations had been reported to SDWIS/FED. 

• SDWIS/FED contained accurate and complete 

information on 82% of the enforcement actions 

found in the states’ records. 

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 1999-2001 timeframe. 

EPA is drafting the current Data Reliability Report 

for the 2002-2004 timeframe. EPA has set a goal 

of 90% 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. 

2004 National Public Water Systems Compliance Report – National Summary Page 9 • December 2006 
• EPA has set up a workgroup with the ASDWA to 

implement its updated 2003 Data Reliability 

Analysis and Action Plan (DRAAP). Implementation 

of the plan will begin in 2005. 

• EPA has negotiated grant conditions with several 

states based upon the 2003 DRAAP. Under these 

grant conditions, the states would follow quality 

assurance/quality control plans for drinking water 

violation data reported to EPA and address the 

differences in interpretation of the regulation. 

• 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. 

The introduction to this report mentioned data 

verification audits and triennial national summary 

evaluations that will be discussed in this section of 

the report. The results of EPA’s second triennial 

review of data quality in SDWIS/FED, Drinking Water 

Data Reliability Analysis and Action Plan (2003) (EPA 

816-R-03- 021, March 2004), includes an evaluation 

of data collected from 1999 through 2001. The first 

triennial review, published in 2000, analyzed drinking 

water data from 1996 through 1998 to establish a 

data quality baseline. The second review indicates 

that data in SDWIS/FED are highly accurate, but still 

incomplete. The first triennial review of data quality 

for the period 1996 through 1998 resulted in a 

detailed data analysis report in 2000 and also 

produced an action plan for states and EPA to work 

together to improve data quality. The plan resulted in 

actions which included training state personnel, 

streamlining reporting to SDWIS/FED, making 

SDWIS error reporting and correction more userfriendly, reducing rule complexity, improving data 

verification audits (DVs), following-up with Regions 

after DVs, and encouraging states to notify water 

systems of sampling schedules annually. Like the 

first review, this second triennial review of data 

quality is largely based on DVs. The DVs, conducted 

between 1999 and 2001, reflect data for 1,890 

randomly selected PWSs in 31 states. To support a 

comparative analysis, a similar set of analyses and 

methods were used in the second review as in the 

first, where possible. 

The data quality of core inventory data was high and 

essentially remained the same as that determined for 

the first assessment (95% in the first triennial review 

versus 96% in the second triennial review). Data 

quality for enforcement data improved from 72% to 

80% and remained of moderate quality. Notably, 

there were 80% fewer enforcement actions from the 

first assessment. Violations were grouped by 

maximum contaminant level (MCL), treatment 

technique (TT), and monitoring and reporting (M/R) 

violations. MCL violations were further broken down 

into Total Coliform Rule (TCR) MCL violations and 

Chemical and Radionuclides MCL violations (i.e., 

Other MCL). 

Violations for the lead and copper rule were not 

included in the analysis. While quality has improved 

considerably in several areas, the analysis of DV 

findings found that the violations data reported by 

states to EPA were very accurate but incomplete in 

several important aspects, as described below. 

• The overall data quality for health-based violations 

(i.e., MCL and SWTR TT) improved from 40% in 

the first round to 65%. The overall data quality for 

M/R violations increased from 9% to 23%. 

• The Total Coliform Rule had the highest data 

quality, improving from 68% in the first assessment 

to 75% in the second. Data quality is lower, but 

improving, for other health-based standards 

including Chemicals and Radionuclides and the 

Surface Water Treatment Rule. Data quality for 

M/R violations has improved, but is still low. 

• Most violation errors are due to incorrect 

compliance determinations by states, that is, 

violations not correctly identified as such. 

— Compliance determination errors accounted for 

slightly more than 50% of all MCL errors, and 

more than 85% of SWTR TT and M/R errors. 

— Half of the M/R errors were due to a failure of 

the state to assign a violation where sample 

data was missing from state files. 

— Data flow errors (data in state databases but 

not in SDWIS/FED) accounted for 9% of all 

errors. 

— Over-reporting of violations found in 

SDWIS/FED accounted for fewer than 2% of all 

errors. This is comparable to findings from the 

first assessment. 

December 2006 • Page 10 2004 National Public Water Systems Compliance Report – National Summary 
• Data quality estimates are similar across water 

system types. 

• More discussions of data quality concerns and 

EPA’s recommendations appear later in this report. 

HOW DOES EPA 

EVALUATE STATE REPORTS? 

EPA reviewed each 2004 annual state report 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 2003. In some 

instances, the data reported by a state in July of 2004 

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 2003 and 2004 Data 

There are some differences in the numbers of 

violations reported in 2003 and 2004. The total 

number of violations increased by 27% from 2003. 

The number of significant violations of monitoring and 

reporting requirements increased by 36,290 — a 

notable 52% increase in violations between 2003 and 

2004. Most of this increase was due to the cyclical 

pattern of the monitoring requirements of Chemical 

Contaminant Group. A smaller percentage of the 

increase is due to the Stage 1 Disinfectants and 

Disinfection Byproducts Rule (DBPR), which in 2004 

required many smaller systems and groundwater 

systems to comply with its monitoring requirements 

for the first time. The number of DBPR monitoring 

and reporting violations increased from less than 

1,000 to over 7,000 violations. In 2004, America’s 

public water systems detected and reported 734 

more violations of health-based standards — a 5% 

increase from 2003. While the number of healthbased violations for the TCR and the SWTR 

decreased slightly, 3% and 16% respectively, the 

increased number of violations of the DBPR more 

than offset the decreases. The total violations include 

health-based and significant monitoring and reporting 

violations, along with violations of the CCR. 

TCR and Chemical Violations 

In 2004, states reported the largest number of 

violations for the Chemical Contaminant Rules. The 

Chemical Contaminant Rules represented the group 

with the largest significant violations for the 

monitoring and reporting requirements. The 55,838 

significant violations of monitoring and reporting 

requirements of the Chemical Contaminant Rules 

represent 52% of all significant monitoring and 

reporting violations reported by the states in 2004. 

The Total Coliform Rule continues to be the most 

violated health-based standard. The 9,544 violations 

of the health-based standards for the Total Coliform 

Rule represent 63% of all reported violations of 

health-based standards in 2004. For Total Coliform 

Rule Health-based violations of the rule decreased 

2004 National Public Water Systems Compliance Report – National Summary Page 11 • December 2006 
3%, while significant monitoring and reporting 

violations decreased 8%. The number of Total 

Coliform Rule violations at all public water systems 

decreased between 2003 and 2004. 

Trends Since 2000 

The number of significant violations reported since 

2000 has been trending upward. During the same 

period roughly 14% of the violations reported are 

violations of health-based standards, while the 

remaining approximately 87% of the violations are 

significant monitoring and reporting violations. 

Likewise the number of significant monitoring and 

reporting violations has increased steadily since 

1999. Violations of the health-based standards 

fluctuated between small increases (5%) to small 

decreases (2–3%) during this period. 

Implementation of Prior 

Year Recommendations 

EPA incorporated the following recommendations for 

fiscal years 2001, 2002, and 2003: 

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. 

Recognizing the importance of consistent, long term 

efforts to protect the public from microbial 

contaminants of drinking water, EPA has made 

assuring compliance with the drinking water microbial 

rules part of its core drinking water enforcement and 

compliance program beginning in fiscal year 2005. 

EPA Regions are working with states to evaluate how 

well public water systems, especially large systems, 

comply with the microbial rules and whether 

enforcement actions are being initiated when 

appropriate. Regions and states are also identifying 

and evaluating microbial risks to watersheds in an 

attempt to focus enforcement and compliance efforts 

on ensuring the safety of drinking water sources. 

Considerable effort will also be devoted to training 

and compliance assistance. EPA will work to build 

the capacity of small public water systems to 

maintain compliance both with established rules and 

with new microbial rules such as the Interim 

Enhanced Surface Water Treatment Rule and the 

Ground Water Rule. In Indian country, where almost 

all public water systems are small, EPA will 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 development and distribution of easyto-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 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 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. 

December 2006 • Page 12 2004 National Public Water Systems Compliance Report – National Summary 
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 

• made a long-term commitment to achieve and 

maintain data quality goals. 

2004 Report Recommendations 

EPA, states, and drinking water stakeholders should 

continue to work cooperatively to improve the quality 

of 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 2003 Data Reliability Analysis and Action 

Plan (DRAAP); 

• 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.

National Summary of Compliance for Public 

Water Systems in Indian Country in 2004 

INTRODUCTION 

This section of the 2004 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 2004, 

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. 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. 

The report also discusses EPA’s compliance 

assistance, enforcement, and financial assistance 

programs. EPA plans to continue its data quality 

efforts during 2005 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 in 

2004 under the section entitled Data Quality. 

FINDINGS 

In 2004, 818 public water systems in Indian 

country served 681,541 users. 

• 589 community water systems served 536,184 

people in their primary residences. 

• 118 non-transient non-community systems (schools 

and factories) served 119,243 people in places 

they frequented. 

• 111 transient non-community systems 

(campgrounds and highway rest stops) served 

26,114 people who passed through.

Almost all public water systems in Indian country 

were small. These small systems provide 

drinking water to the majority of the public who 

drank water in Indian country. 

• 95% of public water systems in Indian country 

serve 3,300 or fewer people. These 776 small 

systems served 56% of the people who received 

water from public water systems in Indian country. 

Conversely, the other 42 public water systems in 

Indian country serve 44% of the people who 

received water from public water systems in Indian 

country. 

As reported to SDWIS/FED, most public water 

systems in Indian country had violations. 

• 508 of 818 water systems (62%) reported healthbased or significant reporting violations.

• 121 health-based violations in Indian country, 

including multiple violations by some systems, were 

reported to SDWIS/FED in 2004. The Maximum 

Contaminant Level (MCL) for the Total Coliform 

Rule (85%) was the health-based standard most 

frequently violated.

Percentage of Health-Based Violations 

The vast majority of violations reported to 

SDWIS/FED in 2004 were for a public water 

system’s significant failure to monitor and report, 

rather than health-based MCL or a treatment 

technique violations detected and reported by a 

system. 

• Of the 6,173 violations reported to SDWIS/FED in 

2004, 5,507 (89%) were significant violations of 

monitoring and reporting requirements. If a system 

did not monitor the quality of its water, it is 

impossible to know if it has violated health-based 

requirements. For this reason, a system’s 

significant failure to monitor and report is a major 

violation that must be addressed and corrected. 

• Public water systems in Indian country represent 

0.5% of all public water systems in the United 

States and were responsible for 5.2% of all 

monitoring and reporting violations at public water 

systems reported to SDWIS/FED in 2004.

As reported to SDWIS/FED, 59% of community

• The Consumer Confidence Report Rule requires all 

community water systems to provide an annual 

report to customers identifying the contaminants 

detected in their water and the health risks 

associated with those contaminants. 

• In calendar year 2004, 243 community water 

systems in Indian country were found to have a 

“significant” violation of the Consumer Confidence 

Report Rule, meaning that the community water 

system completely failed to provide the required 

report. 

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. 

Beginning in federal fiscal year 2005, EPA’s Office of 

Enforcement and Compliance Assurance plans to 

focus increased attention on environmental issues in 

Indian country through implementation of its new 

Tribal National Compliance Priority. One of the goals 

is to improve compliance with drinking water 

standards by the end of fiscal year 2007. Between 

fiscal year 2005 and fiscal year 2008, EPA will work 

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 microbial rules. 

EPA gives information and assistance directly to 

tribal public water system operators, utility managers, 

and owners through training sessions, newsletters, 

telephone support, and system visits. On-site 

technical assistance is provided by engineers and 

qualified staff who work with tribes to assess current 

compliance status, develop monitoring schedules and 

compliance plans, and conduct sanitary 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. 

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. 

Public water systems are 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. 

2004 National Public Water Systems Compliance Report – Section on Indian Country Page 17 • December 2006 
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 giving tribes grants, 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 $6,564,600 in 

FY2004 for activities to support Tribal Public Water 

System Supervision (PWSS) Programs. This financial 

support allows EPA to operate PWSS programs in 

Indian Country and to provide grants to tribes and 

tribal organizations to address various aspects of the 

drinking water program such as: 

• capacity development projects; 

• source water and wellhead protection projects; 

• development of a voluntary operator certification 

program for tribes; and 

• provision of operator training and certification to 

tribal operators. 

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 initial 

set-aside from the 1997 appropriation amounted to 

$19.25 million. Subsequent set-asides have been: 

$10.87 million in fiscal year 1998; $11.625 million in 

fiscal year 1999; $12.3 million in fiscal year 2000; 

$12.347 million in fiscal year 2001; $12.75 million in 

fiscal year 2002; $12.667 million in fiscal year 2003; 

and $12.675 million in fiscal year 2004. 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 2004, EPA Regions reported that 38% 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 a 

slight decrease from 2003 when 39% of facilities did 

not report a violation of a health-based standard, a 

significant monitoring and reporting violation, or a 

significant consumer notification violation. 

During 2004, there was a significant increase in the 

total number of significant violations of monitoring 

and reporting requirements in Indian country (from 

945 in 2003 to 5,507 in 2004). The significant 

increase in the number of monitoring and reporting 

violations was attributed to the triennial monitoring 

requirements for the Chemical Contaminant Group. 

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 health-based violations exist. EPA will 

accomplish these recommendations by: 

• improving the inventory of public water systems in 

Indian country; 

• improving 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; 

• increasing EPA’s field presence, conducting more 

December 2006 • Page 18 2004 National Public Water Systems Compliance Report – Section on Indian Country 
frequent sanitary surveys, and engaging in targeted 

technical and compliance assistance and 

enforcement; 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. 

2004 National Public Water Systems Compliance Report – Section on Indian Country Page 19 • December 2006 
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 year-round 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 federallyrecognized 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. 

Maximum Contaminant Level 

The maximum permissible level of a contaminant in 

water delivered to any user of a public water system. 

2004 National Public Water Systems Compliance Report – Appendix A Page A-1 • December 2006 
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 contaminantspecific 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, among other things, that 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. 

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, radium228, gross alpha, and beta particle/photon 

radioactivity, can occur naturally in water or may 

result from human activity. EPA has established 

MCLs for 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. 

December 2006 • Page A-2 2004 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.

2004 National Public Water Systems Compliance Report – Appendix B Page B-1 December 2006 
__________ 

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 2004, EPA received State Public Water System 

Compliance Reports from 43 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 

Alabama, Alaska, Arizona, Florida, Georgia, 

Kentucky, Massachusetts, Mississippi, Utah, the 

Virgin Islands, and the Navajo Nation. 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 2004, EPA prepared reports for 

those jurisdictions. 

Violations for 2004 

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. 

2004 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 

1 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.

2 MCL and significant monitoring violations for organic, inorganic, total trihalomethane (TTHM), nitrate and nitrite, and radionuclide 

contaminants. 

2004 National Public Water Systems Compliance Report – Appendix B Page B-3 December 2006 
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 

New York reported one violation of a variance or 

exemption in 2004. No other states reported a 

violation of a variance or exemption. 

Where to Obtain the 2004 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
