U.S. Virgin Islands
Public Water System Compliance Report
Calendar Year 2002

1.0 Introduction

Each State and Territory with primacy is required by section 1414(c)(3)(A)(i) of the Federal Safe
Drinking Water Act (SDWA) Amendments of 1996 to prepare an Annual Public Water System
Compliance Report. These annual compliance reports provide information on events or lack of
activity that constituted a violation of the SDWA by a public water system (PWS) at some time
during the calendar year covered by the report.

The Department of Planning and Natural Resources' (DPNR's) intention through this report is to
inform the citizens of and visitors to the United States Virgin Islands (USVI) about how well the
PWSs of the USVI are complying with the requirements of the SDWA. As mandated by law, these
reports must be submitted to the U.S. Environmental Protection Agency (EPA) and made readily
available to the public. The U.S. Virgin Islands Annual Public Water System Compliance Report
for Calendar Year 2002 is available at DPNR's, Division of Environmental Protection (DEP). It
is also available at all public libraries, the University of the Virgin Islands' (UVI) library, UVI's
Water Resource Research Institute, and at local laboratories.

EPA will prepare an annual national violations report which summarizes and evaluates the States'
and Territories' report. EPA's report must also make recommendations concerning the resources
needed to improve compliance with the SDWA, and must include information on PWSs in Indian
reservations.



1.1 PUBLIC WATER SYSTEMS

Federal law defines a public water system as a system that provides water via piping or other
constructed conveyances for human consumption to at least 15 service connections, or serves an
average of at least 25 people for at least 60 days each year. In recognition of the USVI's unique
characteristics and resource management needs, local laws are more stringent, requiring at least 8
service connections or 20 people served for at least 60 days. There are three classifications of public
water systems depending on how regularly a set population is supplied with the water. A PWSs is
designated a Community Public Water System (CPWS) if it regularly serves the same people all
year round (i.e., WAPA and apartment complexes). ANon-transient, Non-community Public Water
System (NTNCPWS) regularly serves the same people for at least six months out of the year (i.e.,
schools and businesses). Transient, Non-community Public Water Systems (TNCPWS)serve
different people at least sixty days out of the year (i.e., hotels and restaurants). For this report, the
use of the acronym "PWS" refers to public water systems of all three types, as well as bottled water
plants and ice manufactures, unless specified in greater detail.

U.S. Virgin Islands
Public Water System Compliance Report
Calendar Year 2002

There were approximately 350 active PWSs on the three islands of St. Thomas, St. Croix and St.
John in calendar year 2002. The number of PWSs is continually changing due to businesses opening
and closing. Some systems also become inactive water systems because they utilize a direct
connection to the Virgin Islands Water and Power Authority (WAPA) as their only source of water.
The Virgin Islands Water and Power Authority's (WAPA) desalinization plants on St. Thomas and
St. Croix are the largest public water systems in the USVI. The WAPA St. Thomas system serves
approximately 29,000 residents on a regular basis, this does not include the transient population
which includes tourists. The WAPA St. Croix system serves approximately 35,000 residents on a
regular basis. The majority of public water systems in the USVI, however, serve between 25 to
1000 individuals. These facilities, for the most part, utilize rainwater collection systems augmented
by trucked water for the provision of potable water. The use of reverse osmosis treatment units to
produce potable water from brackish wells or sea water is increasing throughout the Territory.



1.2 THE PUBLIC WATER SYSTEM SUPERVISION PROGRAM: AN OVERVIEW

EPA established the Public Water System Supervision (PWSS) program under the authority of the
1974 SDWA. As directed by the SDWA and Amendments, EPA sets national limits on contaminant
levels in drinking water to ensure that the water is safe for human consumption. These limits are
known as maximum contaminant levels (MCLs). For some regulations, EPA has established
treatment techniques in place of an MCL to control unacceptable levels of a contaminant in water.
The EPA has also developed frequencies for which public water systems (PWSs) must monitor their
water for contaminants. PWSs are required to report the monitoring data to the States, Territories,
or to EPA. In addition, EPA requires PWSs to monitor for unregulated contaminants to provide data
for the development of future drinking water regulations. Finally, EPA requires PWSs to notify the
public when they have violated these regulations.

The SDWA applies to the 50 States, the District of Columbia, Indian Lands, the U. S. Virgin Islands,
Puerto Rico, American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, and the
Republic of Palau.

The SDWA allows States and Territories to seek EPA approval to administer their own PWSS
programs. The authority to run a PWSS program is called primacy. To receive primacy, States and
Territories must meet certain requirements described in the Federal SDWA and regulations. States
and Territories must adopt drinking water regulations that are at least as stringent as the Federal
regulations. To obtain primacy, a State or Territory must also demonstrate that they can enforce the
requirements of the SDWA.

The United States Virgin Islands promulgated the Virgin Islands Safe Drinking Water Act
(VISDWA) in 1975 under 19 Virgin Islands Code (V.I.C.) Section 1303. In 1977, the drinking
water Rules and Regulations were issued as Title 19, Part VI, Chapter 51, Subchapter 1303, Sections


Page 2









U.S. Virgin Islands
Public Water System Compliance Report
Calendar Year 2002

1303-11 to 1303-53, Drinking Water Standards. After the Virgin Islands demonstrated their ability
to enforce the SDWA, EPA transferred primacy from EPA Region 2 to the USVI Department of
Conservation and Cultural Affairs in 1979. This department was officially restructured and named
the Department of Planning and Natural Resources (DPNR) in 1987 and the authority for
enforcement of the Drinking Water Standards was given to the Commissioner of DPNR by Title 19,
Part VI, Chapter 51, Subchapter 1309. The Virgin Islands' PWSS program is now administered
through the DPNR's Division of Environmental Protection.
Amendments to the VISDWA added Sections 1303-54 through 1303-70 in 1994 to fulfill primacy
requirements which were added to the Federal SDWA by the 1986 Amendments. In January 1998,
DPNR was given the legislative authority to regulate locally produced and imported bottled water
and ice.



1.3 VIOLATIONS OF THE SAFE DRINKING WATER ACT

This Annual Public Water System Compliance Report provides a summary of the number of
violations of the categories listed in section 1414(c)(3) of the Federal Safe Drinking Water Act
Reauthorization. These categories include but is not limited to the following:

* maximum contaminant level (MCL) violations;
* treatment technique requirement (TT) violations;
* significant violations of monitoring and reporting (M/R) requirements;
* violations of variances and exemptions; and
* significant violations of consumer notification requirements.

Primacy States and Territories submit data to the EPA's Safe Drinking Water Information System
(SDWIS/FED) on a quarterly basis. Data include PWS inventory statistics, the incidence of MCL
exceedances, major M/R violations, and TT. The enforcement actions taken against the violators
is also submitted to SDWIS/FED..

Maximum Contaminant Levels (MCL)

Under the Federal SDWA, the EPA sets national limits on the level that contaminants may be
present in drinking water. These limits are known as Maximum Contaminant Levels (MCLs). MCLs
were developed to ensure that the water is safe for human consumption. The levels set by EPA for
each contaminant are amounts of that contaminant that can be present in the water without causing
adverse health effects to humans or pose health risks over a long period of time. The Virgin Islands
SDWA and Drinking Water Standards adopted all of the contaminants and MCLs regulated by the
Federal SDWA.

When a PWS exceeds a MCL, it is required to notify the public of the exceedance. Notices for


Page 3









U.S. Virgin Islands
Public Water System Compliance Report
Calendar Year 2002

violating the MCL of a contaminant with potential to have a "serious adverse effect" must contain
an explanation of the violation, the potential health effects, what the system is doing to correct the
problem, and whether consumers need to use an alternate source of water. Notices must be given
to the public within 24 hours after the occurrence of the violation and the notice must run for at least
three consecutive days. Violations which occurred in 2002 for exceeding MCLs are discussed in
Section 3 of this report .

Monitoring & Reporting Requirements (M/R)

A PWS is required to monitor for water quality parameters and to verify that the levels of
contaminants present in the water do not exceed the MCLs. If the PWS fails to have its water tested
as required by the VISDWA, then a monitoring violation occurs. A reporting violation occurs when
the PWS does not report test results correctly to the primacy agency. In the Virgin Islands, the
proper authority to report monitoring data to is the Division of Environmental Protection's Public
Water System Supervision program.

For this report, significant M/R violations are defined as any major monitoring and reporting
violation that occurred during calendar year 2002. A major M/R violation occurs when no samples
were taken or no results were reported during a compliance period. A compliance period varies for
different contaminants. For example, biological testing for total Coliform must be done on a
monthly basis, on the other hand, testing for nitrates must occur annually. Significant M/R
violations which occurred in calendar year 2002 are discussed in Section 3 of this report.

Treatment Techniques (TT)

For some regulations, the EPA establishes treatment techniques in lieu of an MCL. Treatment
techniques are required for contaminants that laboratories cannot adequately measure. For example,
EPA requires a water disinfection process instead of an MCL for viruses, bacteria, and turbidity.

Under the Lead and Copper Rule, corrosion control treatment is required for the control of lead and
copper in drinking water. Although a specific treatment technique is not dictated by the rules and
regulations, the corrosion control treatment must be reviewed and approved by DPNR before it may
be implemented by the public water system. There were no treatment technique violations in the
Virgin Islands during calendar year 2002.

Variances and Exemptions

Variances and exemptions to specific requirements under the SDWA Amendments of 1996 may be
granted under certain circumstances. If a PWS cannot meet the MCL, due to the characteristics of
the raw water sources reasonably available, a primacy State (Territory) can grant the PWS a variance
from the applicable primary drinking water regulation on the condition that the system install the
best available technology, treatment techniques, or other means which the Administer finds are


Page 4









U.S. Virgin Islands
Public Water System Compliance Report
Calendar Year 2002

available. The State (Territory) must find that the variance will not result in an unreasonable risk
to public health. An exemption may be granted by a primacy State (Territory) to relieve a PWS
from its obligation to comply with a MCL if the systems' noncompliance results from compelling
factors. The PWS will be required to come into compliance with the MCL as expeditiously as
practicable, but no later than three years after the otherwise applicable compliance date. No
variances or exemptions have been given to any PWS in the Virgin Islands, therefore, there were
no violations for this category during calendar year 2002.

Consumer Notification Requirements

A PWS is required to notify persons served when it fails to comply with the requirements of the
SDWA or are facing other situations posing a risk to public health. The 1996 Amendments to the
SDWA require public notification (PN) to include a clear and understandable explanation of the
nature of the violation, its potential adverse health effects, steps that the PWS is undertaking to
correct the violation, and the possibility of the provision of alternative water supplies during the
violation.

In addition to PN, the 1996 Amendments to the SDWA requires community public water systems
(CPWSs) to prepare and provide to their customers annual consumer confidence reports (CCR) on
the quality of the water delivered by the system. These reports provide valuable information to
customers of CPWS and allow them to make personal health-based decisions regarding their
drinking water consumption.

Contaminant Waivers

The Department of Planning & Natural Resources fully utilizes the waiver provisions provided by
the Federal regulations. Under these regulations, DPNR is allowed to develop waiver programs that
reduce or eliminate a public water system's monitoring requirements. Waivers are based mainly
upon two criteria: 1) analytical results of previous sampling, and 2) a vulnerability assessment.
Waivers based on analytical results may use data collected prior to initial monitoring (grandfathered)
or data collected to meet the initial monitoring requirements. A vulnerability assessment involves
two steps: 1) Use Waiver: A determination is made whether a given contaminant was used,
manufactured, and/or stored in an area that possibly would affect the water quality of a public water
system; and 2) Susceptibility Waiver: An assessment of the water source is made to determine a
public water system's susceptibility to contamination.

A number of individual public water systems have received waivers for volatile organic compounds
(VOCs) and inorganic contaminants (IOCs) based on analytical results of previous sampling. DPNR
has initiated a synthetic organic compound (SOC) waiver procedure to determine which SOCs could
qualify for either a use waiver or a susceptibility waiver. DPNR hopes that this procedure will
identify a select group of SOCs for which monitoring may be waived for all public water systems
in the Virgin Islands. Since roof catchment is the most common source of drinking water in the


Page 5

Public Water System Compliance Report
Calendar Year 2002

Virgin Islands, DPNR will consider granting susceptibility waivers to a selected group of small roof
catchment systems on a case-by-case basis if they can provide information which verifies that no
regulated organic contaminants or other toxic chemicals which may cause a concern for adverse
health effects are contained in the roof coating.

3.0 Summary of 2002 Violations

3.1 TOTAL COLIFORM RULE MCL VIOLATIONS

Pathogens are disease causing microorganisms. Bacterial diseases include typhoid, salmonellosis,
shigellosis, bacterial dysentery, and asiatic cholera. Giardia and Cryptosporidium are caused by
protozoans and can cause gastroenteritis. Organisms which cause diseases are usually transmitted
through feces and urine, although they can also be found in animals and soil reservoirs. Many
microorganisms can be found in water. Bacteria from sewage and animal wastes have presented the
most frequent and immediate health risks to public water supplies over the years. Protecting our
water sources and employing proper treatment techniques are key to providing safe drinking water
to the public. It is difficult, not to mention expensive and time consuming, to test for disease-
causing organisms. Since pathogens are primarily transmitted through feces and urine, water which
shows the presence of such contaminants is considered unfit for human consumption. Coliform
bacteria is excreted in much larger numbers than pathogens. Therefore, Coliform bacteria,
specifically the presence of fecal Coliform and Escherichia Coli bacteria, are used as the best (and
most easily tested for) indicators of pathogenic contaminated water. While the presence of Coliform
bacteria does not prove that the water is dangerous, the absence of these bacteria serves as evidence
that the water is free of pathogens.

All public water systems in the Virgin Islands are required to have their drinking water supply tested
for Coliform bacteria on a monthly basis. Failure to test the water or submit the test results, or
failure to meet the maximum contaminant level (MCL) for total Coliform are all violations of the
Total Coliform Rule under the Safe Drinking Water Act.

Compliance with the TCR MCL is determined simply by the presence or absence of total Coliform
bacteria in a sample. A public water system which collects fewer than 40 samples per month
exceeds this MCL when more than one sample is total coliform-positive. On the other hand, a
system which collects more than 40 samples each month exceeds the total coliform MCL if more
than 5% of the samples collected are total coliform-positive. Most of the water systems in the
Virgin Islands are only required to collect one sample each month. WAPA, since it serves a much
larger population, is required to take 30 bacteriological samples on St. Thomas and 40
bacteriological samples on St. Croix each month.

If a sample tests positive for total coliform, the lab will further analyze the water sample for fecal
Coliform. If the water sample only tests positive for total coliform, it is considered a non-acute
MCL violation. If the water sample also tests positive for fecal coliform, it is considered an acute
MCL violation. The reason for differentiating between acute and non-acute MCL violations is the
impending health effects that may be caused to an individual by the presence of fecal Coliform in
the water. The difference in enforcement of these two types of violations is the time frame in which
the PWS must notify users of the water supply of the MCL violation.


Page 12









U.S. Virgin Islands
Public Water System Compliance Report
Calendar Year 2002

There were 64 violations of the Total Coliform MCL in 2002. Of approximately 350 PWSs in the
Virgin Islands. Fifty-one (51) systems were responsible for these violations. This represented
approximately 18.3% of the Territory's PWSs. The number of total coliform MCL violations
decreased by approximately 15.8% from 2001 to 2002.

Each year a small percentage of PWS violate the MCL for Total Coliform. This percentage is
possibly kept low as a result of continued technical assistance and educational outreach by the
PWSS program. Each year the PWSS program conducts inspections of public water systems, called
sanitary surveys. Sanitary surveys are on-site inspections of the water source, facilities, equipment,
operation and maintenance procedures, and management practices of a public water system for the
purpose of evaluating the adequacy of the system for producing and distributing safe drinking water.
Sanitary surveys provide the opportunity for discussion of the importance of providing safe drinking
water to the public. It also provides an opportunity to educate public water system operators on
proper chlorination and other disinfection techniques. Recommendations on improvements to the
facility which will result in the production of better water quality are provided to the PWS by the
inspectors. This open dialogue between public water system operators and managers, and DPNR
has directly benefitted the public and their health through improved water quality.



3.2 TOTAL COLIFORM RULE MONITORING/REPORTING VIOLATIONS

A PWS is required to monitor for total Coliform bacteria on a monthly basis. The number of
samples required each month depends on the population served by the PWS. A monitoring violation
occurs when the PWS fails to have its water tested or fails to collect the required number of routine
and/or repeat samples as mandated by the Virgin Islands Safe Drinking Water Act. A reporting
violation occurs when the PWS does not report test results correctly to the primacy agency.

There were 57 monitoring/reporting (M/R) violations of the Total Coliform Rule. Of approximately
350 PWSs in the Virgin Islands, thirty-six (36) PWSs were responsible for all of these violations.
This represents approximately 10% of the Territory's PWSs. Nine monitoring violations occurred
as a result of eight of these PWSs failure to collect the required repeat samples after a positive
routine sample. M/R violations of the Total Coliform Rule, cited during 2002 decreased by
approximately 17% from the number of 2001 M/R violations. This decrease in TCR M/R violations
may, again, be attributed to a more aggressive outreach policy by the PWSS program.



3.3 NITRATE MONITORING

Nitrate is used in fertilizer and is found in sewage and waste from human and/or farm animals and
generally gets into drinking water from those activities. Excessive levels of nitrate in drinking water
has caused serious illness and sometimes death in infants under six months of age. The MCL for


Page 13









U.S. Virgin Islands
Public Water System Compliance Report
Calendar Year 2002

Nitrate is 10 mg/l. Exceeding this concentration constitutes a violation of the MCL for Nitrate. No
PWS exceeded the MCL for Nitrate in 2002.

PWSs are required to monitor for Nitrate on a annual basis. Failure to perform this monitoring as
required by the Virgin Islands Safe Drinking Water Act, constitutes a monitoring violation. A
monitoring violation also occurs when the PWS does not report analytical samples results to the
primacy agency. Thirty-four (34) public water systems failed to monitor for Nitrate in 2002. This
represents approximately 9.7% of the Territory's PWSs and a 52% decrease in the number of
violations issued for failing to monitor for Nitrate during 2001.

3.4 VOLATILE ORGANIC CONTAMINANTS (VOC) MONITORING

VOCs are chemicals derived from petroleum and refined petroleum products that produce vapors
readily at room temperature and normal atmospheric pressure. Volatile organic chemicals include
gasoline, industrial chemicals and solvents. Volatile industrial solvents have many uses because of
their ability to dissolve oils, fats, resins, rubber and plastic. Only community public water systems
and non-transient, non-community public water systems are required to monitor for VOCs. Initially
monitor for this group of contaminants occur on a quarterly basis for one year. Subsequent
monitoring must occur annually, unless a PWS is granted a waiver by DPNR. Failure to perform
this monitoring as required by the Virgin Islands Safe Drinking Water Act, constitutes a monitoring
violation. A monitoring violation also occurs when the PWS does not report analytical samples
results to the DPNR. There were no M/R violations for VOCs in 2002.

There are different MCLs for the twenty-one regulated VOCs. Exceeding any of these established
limits constitutes a violation of the MCLs for VOCs. No PWS exceeded any of the MCLs for
VOCs in 2002.




3.5 DISINFECTANT AND DISINFECTION BY-PRODUCTS (D/DBP) MONITORING

Many PWSs treat their water with a chemical disinfectant in order to inactivate disease causing
pathogens. Chlorine is a commonly used disinfectant for the effective control of many harmful
microorganisms. Chlorine, however, reacts with organic matter and form the group of contaminants
known as the trihalomethanes. CPWSs which serve a population of 10,000 or more and which add
a disinfectant are required to monitor for Total Trihalomethanes (TTHM) on a quarterly basis.
Compliance is based on a running annual arithmetic average, computed quarterly, of quarterly
averages of all samples collected Failure to perform this monitoring as required by the Virgin
Islands Safe Drinking Water Act, constitutes a monitoring violation. A monitoring violation also
occurs when the PWS does not report analytical samples results to the DPNR. There were no M/R
violations for TTHM in 2002.

The MCL for TTHM is 0.10 mg/1. Exceeding this concentration constitutes a violation of the MCL


Page 14









U.S. Virgin Islands
Public Water System Compliance Report
Calendar Year 2002

for TTHM. No PWS exceeded the MCL for TTHM in 2002.



3.6 SYNTHETIC ORGANIC CONTAMINANTS (SOC) MONITORING

Synthetic Organic Contaminants, as the name implies, are man made compounds. The are found
in herbicides, pesticides, PCB transformers, flame retardants and sealants for roofs, cisterns and
water storage tanks. In the U.S. Virgin Islands, CPWS are the only type of PWS required to
monitor for SOCs. Initially monitor for this group of contaminants occur on a quarterly basis
for one year. Subsequent monitoring must occur annually, unless a PWS is granted a waiver by
DPNR. Failure to perform this monitoring as required by the Virgin Islands Safe Drinking
Water Act, constitutes a monitoring violation. A monitoring violation also occurs when the
PWS does not report analytical samples results to the DPNR. There were no M/R violations for
VOCs.

There are different MCLs for the twenty-one regulated VOCs. Exceeding any of these
established limits constitutes a violation of the MCLs for VOCs. There were no MCL violations
for VOCs.



3.7 INORGANIC CONTAMINANTS (IOC) MONITORING

Inorganic contaminants include the regulated metals, such as barium, cadmium, cyanide, lead ,
copper, mercury and nickel, and asbestos, nitrate and nitrite. Contaminant sources of the regulated
metals are mineral deposits and industrial activities such as metal finishing, painting, steel
processing and the manufacturing of fertilizer products and glass. Asbestos enters drinking water
from natural deposits or from asbestos cement pipes that are used for carrying water. Nitrate and
Nitrite enter drinking water from natural deposits or from agricultural activity and sewage. Only
community public water systems and non-transient, non-community public water systems are
required to monitor for IOCs. Initially monitor for this group of contaminants occur on a annual
basis. Failure to perform this monitoring as required by the Virgin Islands Safe Drinking Water Act,
constitutes a monitoring violation. A monitoring violation also occurs when the PWS does not
report analytical samples results to the DPNR. Monitoring violations for Nitrate is discussed in
section 3.3. There were no M/R violations for the other IOCs in 2002

There are different MCLs for the IOCs. Exceeding any of these established limits constitutes a
violation of the MCLs for IOCs. There were no MCL violations for IOCs in 2002.





3.8 LEAD AND COPPER MONITORING


Page 15










U.S. Virgin Islands
Public Water System Compliance Report
Calendar Year 2002


Community and Non-Transient, Non-Community, Public Water Systems are required to initially
monitor for Lead and Copper during two consecutive 6-month sampling periods. The number of
samples required to be collected during each sampling period is based on the population served by
a PWSs. Failure to perform this monitoring as required by the Virgin Islands Safe Drinking Water
Act, constitutes a monitoring violation. There are no MCLs for lead and copper. EPA has, however,
established Action Levels (AL) for lead and copper. Exceeding an AL is not a violation of the Safe
Drinking Water Act. PWSs exceeding the ALs for lead and copper are required to install optimal
corrosion control treatment. Failure to install treatment or recommend a corrosion control treatment
to the primacy agency constitutes a treatment technique violation of the Safe Drinking Water Act.


3.9 SIGNIFICANT NONCOMPLIANCE (SNC)


Significant noncompliance occurs when a public water system violates any water quality monitoring
requirement for three (3) or more consecutive months (i.e Total Coliform monitoring) or two (2) or
more compliance periods (i.e. chemical parameter monitoring requirements). Significant
noncompliance is considered the most reprehensible and significant violation under the SDWA.

U.S. Virgin Islands
Public Water System Compliance Report
Calendar Year 2002

APPENDIX A:
DEFINITIONS

Inorganic Contaminants: Non-carbon-based compounds such as metals, nitrates, and asbestos.
These contaminants are naturally-occurring in some water, but can get into water through
farming, chemical manufacturing, and other human activities. EPA has established MCLs
for 15 inorganic contaminants [40 CFR 141.62].

Lead and Copper Rule: This rule established national limits on lead and copper in drinking
water [40 CFR 141.80-91]. Lead and copper corrosion pose various health risks when
ingested at any level, and can enter drinking water from household pipes and plumbing
fixtures. States report violations of the Lead and Copper Rule in the following six
categories:

Maximum Contaminant Level (MCL): The highest amount of a contaminant that EPA allows
in drinking water. MCLs ensure that drinking water does not pose either a short-term or
long-term health risk. MCLs are defined in milligrams per liter (parts per million) unless
otherwise specified.

Monitoring: EPA specifies which water testing methods the water systems must use, and sets
schedules for the frequency of testing. A water system that does not follow EPA's
schedule or methodology is in violation [40 CFR 141].

States must report monitoring violations that are significant as determined by the EPA
Administrator and in consultation with the States. For purposes of this report, significant
monitoring violations are major violations and they occur when no samples are taken or
no results are reported during a compliance period. A major monitoring violation for the
surface water treatment rule occurs when at least 90% of the required samples are not
taken or results are not reported during the compliance period.

Organic Contaminants: Carbon-based compounds, such as industrial solvents and pesticides.
These contaminants generally get into water through runoff from crop land or discharge
from factories. EPA has set legal limits on 54 organic contaminants that are to be
reported [40 CFR 141.61].

Radionuclides: Radioactive particles which can occur naturally in water or result from human
activity. EPA has set legal limits on four types of Radionuclides: radium-226, radium-
228, gross alpha, and beta particle/photon radioactivity [40 CFR 141].

Total Coliform Rule (TCR): The Total Coliform Rule establishes regulations for
microbiological contaminants in drinking water. These contaminants can cause short-
term health problems. If no samples are collected during the one month compliance
period, a significant monitoring violation occurs.

Public Water System Compliance Report
Calendar Year 2002

Acute MCL violation: Indicates that the system found fecal coliform or E. coli, potentially
harmful bacteria, in its water, thereby violating the rule.

Non-acute MCL violation: Indicates that the system found total coliform in samples of its water
at a frequency or at a level that violates the rule. For systems collecting fewer than 40
samples per month, more than one positive sample for total coliform is a violation. For
systems collecting 40 or more samples per month, more than 5% of the samples positive
for total coliform is a violation.

Major routine and follow-up monitoring violation: Indicates that a system did not perform
any monitoring.

Treatment Techniques: A water disinfection process that EPA requires instead of an MCL for
contaminants that laboratories cannot adequately measure. Failure to meet other
operational and system requirements under the Surface Water Treatment and the Lead
and Copper Rules have also been included in this category of violation for purposes of
this report.

Violation: A failure to meet any state or federal drinking water regulation.
