Introduction
This document is intended to be used by water suppliers who are preparing their annual drinking
water consumer confidence reports (CCRs) [40 CFR Part 141, Subpart O]. This guide explains
the requirements for report content, format, and distribution that the U.S. Environmental
Protection Agency (EPA) established in the CCR Rule, published in the Federal Register on
August 19, 1998 (63 FR 44512), and in subsequent revisions to the rule through calendar year
2008.
As the system operator/manager, you are a guardian of the quality of your drinking water supply
and of the public health in your community. It is important to communicate to your customers,
and your customers have the right to know, the source of their water and what is in the water
they drink. CCRs help consumers make informed choices that affect the health of themselves and
their families. They also encourage consumers to consider and appreciate the challenges of
delivering safe drinking water. Educated consumers are more likely to help protect their drinking
water sources and to understand the true costs of safe drinking water.
Water suppliers, states, and EPA work to educate consumers about the sources, quality, and
delivery of their drinking water, and to increase their involvement in decisions about it. Systems
and states encourage citizens to participate in decision-making regarding source water
assessment and protection programs and use of the Drinking Water State Revolving Fund
(DWSRF), which provides funding for infrastructure upgrades and treatment improvements.
Consumers who are familiar with the basic drinking water information in CCRs will be able to
participate more effectively in these processes.
Since the last revision of this document in April 2005, EPA has published the:
Stage 2 Disinfectants and Disinfection Byproducts Rule (Stage 2 DBPR) - January 4,
2006.
Long-Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR) - January 5, 2006.
Ground Water Rule (GWR) - November 8, 2006.
Lead and Copper Rule (LCR) Short Term Regulatory Revisions and Clarifications (LCR
Revisions) - October 10, 2007.
Miscellaneous corrections to existing rules.
Miscellaneous revisions or additions to analytical methods, detection limits and
compliance dates.
Preparing Your Drinking Water CCR 1 April 2010
-------
These rules create new requirements that may be subject to inclusion in a CCR. (Note: if you are
uncertain about which requirements apply to your system and when, contact your state.)
Stage 2 DBPR: Based on a system's schedule under the Stage 2 DBPR, systems will
change from reporting their system-wide running annual average (RAA) to reporting the
highest locational running annual averages (LRAAs) for total trihalomethanes (TTHM)
and five haloacetic acids (HAAS). Systems will also report the range of sample results for
all monitoring locations. If more than one location exceeds the TTHM or HAAS
maximum contaminant level (MCL), the system must include the location running annual
average for all locations that exceed the MCL.
During the calendar years that the water system collects samples for the Initial
Distribution System Evaluation (IDSE), systems must include IDSE sample results when
reporting the range of TTHM and HAAS.
Systems must also report in their CCR if they failed to monitor for TTHM or HAAS.
Information regarding this new rule is on pages 12 and 36-40 of this document.
LT2ESWTR: Based on a system's schedule under the LT2ESWTR, a surface water
system must report violations in their CCR related to this rule. These include:
- Treatment technique violations for: failure to address an uncovered finished water
reservoir (i.e., cover or treat); failure to determine and report a bin classification
(filtered systems); failure to calculate and report a mean Cryptosporidium level
(unfiltered systems); failure to provide, install or maintain a required level of
additional treatment (filtered systems); failure to achieve the required inactivation
level or maintain it once achieved (unfiltered systems); and failure to install a
second disinfectant (unfiltered systems).
- Monitoring and reporting violations for failure to monitor for Cryptosporidium for
any three months, failure to monitor for E. coli and turbidity, and failure to notify
the state before making a change to a disinfection practice. In addition, positive
results of any Cryptosporidium monitoring must be reported in the CCR, whether
taken for compliance with LT2ESWTR or voluntarily.
Note: Surface water systems that collected E. coli samples at the source under
LT2ESWTR are not required to report these results in their CCR. However, they are
required to discuss if they failed to monitor for E. coli at the source.
Information regarding this new rule is on pages 14-15 and 48 of this document.
GWR: Beginning with the report due July 1, 2010, a ground water system must report
any detection of a fecal indicator (E. coli, enterococci, coliphage) at the source and
provide special notice regarding the detect. A ground water system must also provide
special notice for any significant deficiency that is uncorrected by the end of the calendar
Preparing Your Drinking Water CCR 2 April 2010
-------
year. In addition, a ground water system must report violations of the GWR in their CCR
which include:
- Treatment technique violations for failure to maintain 4-log treatment of viruses
for more than 4 hours for systems required to treat to 4-log; failure to take
corrective action within the required timeframe or be in compliance with a state-
approved corrective action plan and schedule for a fecal indicator-positive source
sample; and failure to take corrective action within the required timeframe or be
in compliance with a state-approved corrective action plan and schedule for a
significant deficiency.
- Monitoring and reporting violations for failure to conduct source water
monitoring for fecal indicators or failure to conduct compliance monitoring.
Information regarding this new rule is on pages 13, 15, 20-22, and 59-51 of this
document.
LCR Revisions: Beginning with the report due July 1, 2009, systems whose states
adopted the LCR Revisions before January 1, 2009, must include a statement about lead
in every report released to the public. For systems whose states have not adopted the
revisions by January 1, 2009, the lead information statement must be included in reports
due by July 1,2010.
Information regarding these modifications is on page 25 of this document.
This document includes recommendations for improving the effectiveness of your CCR,
examples of reporting formats, and completed CCRs. Additional information for completing
your CCR is available on the EPA Web site at: www.epa.gov/safewater/ccr/index.html. You can
find specific information about:
Appendix A to Title 40 of the Code of Federal Regulations (CFR), Part 141, Subpart O
(referred to as Appendix A to Subpart O in the remainder of this document) which lists
contaminants, their MCLs in traditional MCL units, conversion factors for converting
traditional MCL units to the more easily understood MCLs in CCR units, maximum
contaminant level goals (MCLGs), major sources of contaminants, and health effects
language (located on EPA's Web site at www.epa.gov/safewater/ccr/regulations.html and
in Appendix F of this guidance document).
The list of unregulated contaminants applicable for monitoring during 2008 through 2010
under the Unregulated Contaminant Monitoring Rule (located on EPA's Web site at
www.epa.gov/safewater/ccr/regulations.html).
Preparing Your Drinking Water CCR 3 April 2010
-------
I. What is a consumer confidence report?
In 1996, Congress amended the Safe Drinking Water Act (SDWA). Among other things, this
amendment added a provision requiring that all community water systems deliver to their
customers a brief water quality report annually. These CCRs summarize information that your
water system already collects to comply with regulations. The CCR Rule does not require you to
engage in any new monitoring to complete your CCR.
The CCR includes information on your source water, the levels of any detected contaminants,
compliance with drinking water rules (including monitoring requirements), and some educational
language. Most reports will fit on a few sheets of paper. A report that contains too much
information or is full of technical jargon can discourage consumers from learning about their
drinking water. Beyond a mandatory requirement, a CCR is an opportunity to communicate the
value of water (both as a product and as a service), to promote wise use, to build community trust
and customer satisfaction, and to encourage investment in resource protection and infrastructure
(AwwaRF, 2008).
II. Who must prepare a consumer confidence report?
Every community water system (serving at least 15 service connections and/or 25 people year
round) must prepare and distribute a report. These systems typically include cities, towns,
homeowners associations, residential subdivisions, manufactured housing communities, and
other institutions where people live full-time such as nursing homes and prisons.
A system may contract with a laboratory to provide monitoring data analysis or CCR
development assistance. If the system chooses to use a laboratory to assist with the development
of the CCR, the system must work with the laboratory to make sure that all of the required
elements are included in the CCR. Otherwise, a system may need to add the missing elements.
Regardless of whether the laboratory or system prepares the CCR, the system is ultimately
responsible for the content and must always distribute the CCR to its customers.
Wholesale systems (drinking water systems that sell water to one or more systems) are not
responsible for creating a CCR for their consecutive systems (systems that purchase water from
the wholesale system), nor are they responsible for providing data on contaminants that the
consecutive system monitors (such as total coliforms, lead, or TTHMs). However, wholesale
systems are responsible for providing the consecutive system with relevant source information
and monitoring and compliance data so that the consecutive system can include this information
in their CCR. In some cases, a consecutive system will contract with the wholesale system to
produce the report. There are several options in this relationship. If the consecutive system had
no new data to add, it could simply send out the wholesale system's CCR with a cover letter
explaining their relationship. If the consecutive system did need to add data, it might choose to
reprint the wholesaler system's CCR with a new title/letterhead and the additional data. Either of
Preparing Your Drinking Water CCR 4 April 2010
-------
these options is acceptable. Regardless of who produces the report, the consecutive system is still
responsible for ensuring that its customers receive a report containing all required content.
III. When must a water system distribute its report?
You must deliver your annual report to consumers by July 1 of each year. The reports are based
on calendar-year data, so your report will include data collected between January and December
of the previous calendar year. For example, data collected between January and December 2010
must be reported in the 2010 CCR, which is due to customers by July 1, 2011. A new community
water system must deliver its first report by July 1 of the year after its first full calendar year in
operation, and annually thereafter.
A wholesale system must provide the consecutive system with monitoring data and other
information by April 1 of each year unless the two systems make a different contractual
agreement. This gives the consecutive system enough time to prepare their CCR before the
deadline of July 1.
IV. What content is required in the report?
This guidance describes EPA's requirements for a CCR (using the words "must" and "shall")
and suggestions (using the words "encourage," "should," and "may") that will help your
customers understand the report. Your state's CCR Rule may require more information, so be
sure to check with your state drinking water program or other relevant state or local authorities.
EPA encourages you to tailor the content of your CCR to local conditions. If you think that an
added picture or graph would help your customers to understand your report, add it. If your
customers would benefit from an explanation of your need for new treatment facilities, tell them.
Provide information to your consumers in a way that they understand. For example, when
discussing units of measure, explain it in terms that a consumer may understand: if an Olympic-
sized swimming pool were filled with ping-pong balls, a ppb would be equivalent to one ping
ball in that pool. As long as any additional educational information is consistent with, and not
detracting from, the purpose of the report, you may add it. For example, the CCR Rule does not
require a title for your report. However, you should give your report a title to catch the
customer's attention. You may call the report a "Consumer Confidence Report," a "Water
Quality Report," or choose another title.
Customers are most interested in a clear statement of whether or not their drinking water meets
all EPA and state standards. Although it is not required by the regulations, you will help your
customers if you tell them whether their water met all drinking water standards. Be cautious in
using the word "safe" since water that meets standards and is safe for most people might not be
safe for infants, chemotherapy patients, or people with HIV/AIDS. Also, using the term "safe" if
you have had an MCL or action level (AL) exceedance can be misleading to the customer.
Preparing Your Drinking Water CCR 5 April 2010

EXAMPLE-Last year, as in years past, your tap water met all EPA and state drinking water
health standards. Local Water vigilantly safeguards its water supplies and once again, we
are proud to report that our system has never violated a maximum contaminant level or any
other water quality standard, [or, if you had a violation, begin with: Last year, we conducted
more than tests for over 80 contaminants. We only detected of those contaminants, and
found only at a level higher than EPA allows. As we told you at the time, our water
temporarily exceeded drinking water standards. For more information, see the paragraph
marked Violation on the back] This brochure is a snapshot of last year's water quality.
Included are details about where your water comes from, what it contains, and how it
compares to EPA and state standards. We are committed to providing you with this
information because informed customers are our best allies.
Examples of CCRs are included in Appendix E of this document.
Research conducted by the American Water Works Association Research Foundation (AwwaRF,
2004) described three important phases in facilitating customer understanding of the information
in a CCR:
Initial Sort: Customers are less likely to discard the CCR as "junk mail" if it looks
professional, distinct, and prominently displays the utility's name. However, glossy full-
color reports are not necessary.
Skimming: For the reader who chooses to skim the document, important and concise
messages about water quality that are prominently displayed will attract attention.
However, statements about the safety of water should not be over-stated, and specific
warnings regarding health risks for sensitive sub-populations must be included. The use
of color will draw attention and can be used to guide the reader through the CCR. Maps,
simple tables, and photographs present information quickly and effectively.
Reading: If the above challenges are addressed, a customer will hopefully choose to read
the entire CCR. The document should not be designed to persuade the reader, it should
inform the reader. A brief table of contents at the very beginning will help to guide the
reader. Contaminant tables should be simple and should not require special instructions.
The use of large fonts in an uncrowded format is desirable. Discussions regarding
detected contaminants are helpful and should promote credibility.

Each item is discussed in detail below.
Item 1: Required Information about the Water System
You must provide the following information about your water system:
The name and telephone number of a person at the water system who can answer
questions about the report.
Preparing Your Drinking Water CCR
April 2010
-------
A list of known opportunities for public participation in decisions that affect drinking
water quality (e.g., time and place of regularly scheduled water board or city/county
council meetings). If you do not have regularly scheduled meetings, you should tell
customers how to get information when meetings are announced.
Systems that have a large proportion of non-English speaking residents must include
information in the appropriate language(s) expressing the importance of the CCR or the CCR
must contain a phone number or address where residents may contact your system to obtain a
translated copy of the CCR or assistance in the appropriate language. The state or EPA will make
the determination of which systems need to include this information.
Translations of the following text are provided in Appendix A of this document:
"This report contains important information about your drinking water. Have someone
translate it for you, or speak with someone who understands it. "
Item 2: Source(s) of Water
Describe your water source(s) (ground water, surface water, or a blend) including the commonly
used name(s) (if such a name exists), and the general location(s). EPA encourages you to provide
a simple map of your system's sources without a detailed description of their locations for
security reasons.
For some more complicated systems, explaining your various interconnections and back-up
sources may be difficult, but it is important that consumers understand that the source of their
water may vary during the year. Remember to include in your table of detected contaminants
(Item 4) monitoring data for any "additional" sources if you use water from them. If your
situation is complex, you may need to describe the types of sources and how they are used.
If a source water assessment has been completed, you should have a copy of it. Let customers
know how to obtain the results of the assessment. In addition, include in the CCR a brief
summary of your source water's susceptibility to contamination based on the findings of the
assessment.
In cases where the information is available, EPA encourages you to highlight potential
significant sources of contamination in the source water area. Including this information in the
CCR is an opportunity for you to provide customers with an explanation for why a contaminant
is present in the source water.
EPA also encourages public water suppliers to use the CCR as a way to discuss appropriate
source water protection actions that are in the planning stages or are already in place. This
discussion is an ideal opportunity to invite public participation in locally based source water
protection efforts as well. Systems may also wish to provide tips for consumers in the CCR on
Preparing Your Drinking Water CCR 8 April 2010
-------
ways they can protect the source water Remember, this is your opportunity to educate your
customers about the impacts they and others have on the quality of source water.
Examples of how to include the source water assessment information and source water
protection tips in your CCR are available in Appendix D, Tables D-2 and D-3 of this document.
Item 3: Definitions
Every CCR must include definitions of key terms that consumers will need to understand the
contaminant data. You must use the definitions listed below.
Maximum Contaminant Level (MCL): The highest level of a contaminant that is
allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best
available treatment technology.
Maximum Contaminant Level Goal (MCLG): The level of a contaminant in drinking
water below which there is no known or expected risk to health. MCLGs allow for a
margin of safety.
Include the following definition only if your water system operated under a variance or
exemption during the calendar year that the CCR describes:
Variances and Exemptions: State or EPA permission not to meet an MCL or a
treatment technique under certain conditions.
Include the following definitions only if your CCR requires the use of these terms:
Treatment Technique (TT): A required process intended to reduce the level of a
contaminant in drinking water.
Action Level (AL): The concentration of a contaminant which, if exceeded, triggers
treatment or other requirements which a water system must follow.
Maximum Residual Disinfectant Level (MRDL): The highest level of a disinfectant
allowed in drinking water. There is convincing evidence that addition of a disinfectant is
necessary for control of microbial contaminants.
Maximum Residual Disinfectant Level Goal (MRDLG): The level of a drinking water
disinfectant below which there is no known or expected risk to health. MRDLGs do not
reflect the benefits of the use of disinfectants to control microbial contamination.
Preparing Your Drinking Water CCR 9 April 2010
-------
Item 4: Reporting Levels of Detected Contaminants
An essential part of the CCR is the table that shows the highest level of each detected
contaminant (this is usually the value you report to the state to determine compliance) and the
range of levels of that contaminant you found during the CCR calendar year (assuming more
than one sample was collected). A detected contaminant is any "regulated" or "unregulated" (as
required under 40 CFR 141.40) contaminant detected at or above its method detection limit
(MDL).
See the EPA Web site at www.epa.gov/safewater/ccr/regulations.html for a list of contaminants
and MDLs. Do not include in the table, contaminants that are not detected or are detected
below the MDL. Your state may have lower MDLs that take precedence over EPA's. If you are
unsure of the MDL for a contaminant, and your laboratory reports a value greater than zero,
include that in your CCR.
The main table of detected contaminants must contain only data about regulated contaminants
(contaminants subject to an MCL, MRDL, TT, or AL), and unregulated contaminants for which
EPA or the state requires monitoring under 40 CFR 141.40. See Item 5 for special instructions
about Cryptosporidium and radon. You may make several tables to separate regulated
contaminants from those that do not have MCLs (such as lead and copper or turbidity), or those
that are currently unregulated. You may want to organize your table(s) by contaminant type (e.g.,
microbial, inorganic) or sampling site (e.g., treatment plant, distribution system). Appendix B of
this document provides examples for interpreting and reporting detected contaminants in your
CCR.
To ensure that consumers can easily compare detected contaminant levels to their MCLs, your
table must display the MCL for each contaminant in units that express it as a number greater than
1.0. Report the MCLG and level of the detected contaminant in the same units as the MCL. For
example, atrazine is usually reported in parts per million (ppm) [or milligrams per liters (mg/L)].
It is easier for customers to see that your water contains atrazine at a level 10 times lower than
the MCL if you report the MCL as 3 parts per billion (ppb) and the detected level as 0.3 ppb than
if you were to report the MCL as 0.003 ppm and the detected level as 0.0003 ppm. In this case,
you convert by multiplying the detected level and MCL by 1000. Appendix A to Subpart O
(available on the EPA Web site at www.epa.gov/safewater/ccr/regulations.html and in Appendix
F of this document) includes conversion factors for each contaminant for converting the MCL to
a number equal to or greater than 1.0. When you round results to determine compliance, round
before multiplying the results by the factor listed in the table. If the MCL units for a contaminant
are already expressed in a number greater than 1.0 (e.g., the MCL for barium is 2 ppm), there is
no conversion factor to apply to the MCL or detected contaminant level.
Report any additional monitoring data (i.e., voluntary monitoring data) in another section of the
CCR, separated from the detected contaminant data. If you want to list all the contaminants that
you monitored for but did not detect, you must do so outside of the table of detected
Preparing Your Drinking Water CCR 10 April 2010
-------
contaminants. If you choose to report on secondary MCLs, or if your state requires this reporting,
do so outside of the main table.
The CCR includes data from monitoring completed during the previous calendar year. However,
if you have monitoring waivers, or for another reason monitor less than once per year, use your
most recent data even though it is outside of the calendar year. For example, if you monitor once
every three years for lindane and detect lindane in a sample, report the same detection level each
of the three years until you take a new sample. In addition, you do not need to report monitoring
results that are more than 5 years old.
If the CCR contains detection data that is not from the calendar year indicated, the table must
show the date of monitoring and the CCR must contain a brief statement explaining that the data
presented is from the most recent monitoring done in compliance with regulations.
EXAMPLE-The state allows us to monitor for some contaminants less than once per year
because the concentrations of these contaminants do not change frequently. Some of our
data, though representative, are more than one year old.
THE TABLE MUST CONTAIN THE FOLLOWING, FOR EACH DETECTED
CONTAMINANT:
1) If the contaminant is regulated by a MCL or MRDL:
a) The MCL or MRDL, expressed as a number equal to or greater than 1.0.
b) The MCLG or MRDLG, expressed in the same units as the MCL or MRDL.
c) The level of that contaminant expressed in the same units as the MCL and MCLG or
MRDL and MRDLG.
2) If the contaminant is regulated by a treatment technique (TT):
a) Put the letters "TT" in place of the MCL.
b) Put "N/A" (not applicable) in place of the MCLG when no MCLG is listed in Appendix
A to Subpart O (available on the EPA Web site at
www.epa.gov/safewater/ccr/regulations.html and in Appendix F of this document).
3) If the contaminant is regulated as an action level (AL):
a) The AL expressed as a number equal to or greater than 1.0.
b) The MCLG expressed in the same units as the AL for copper and zero for lead.
Preparing Your Drinking Water CCR 11 April 2010
-------
4) If the contaminant is unregulated:
a) The average level of that contaminant and the range of results.
5) The level of the contaminant must be represented as follows:
a) If compliance is determined based on annual or less frequent sampling (many inorganic
chemical contaminants), include the highest detected level at any sampling point and the
range of detected levels, if applicable (example table provided in Appendix B).
b) If compliance is determined based on a running annual average of all the samples taken
from a sampling point (i.e., contaminants monitored more frequently than annual),
include the highest average as reported to the state for compliance purposes and the range
of detected levels. As stated above, a detected contaminant is any regulated or
unregulated contaminant (as required under 40 CFR 141.40) detected at or above its
MDL.
c) For TTHM and HAAS samples:
- If compliance is determined based on a system-wide running annual average [under
the Stage 1 Disinfectants and Disinfection Byproducts Rule (Stage 1 DBPR)], include
the system-wide average and the detected range for the system (example table
provided in Appendix B).
- If compliance is determined based on a locational running annual average (under the
Stage 2 DBPR), include the highest locational running annual average for TTHM and
HAAS and the range of individual samples results for all monitoring locations. If
more than one monitoring location exceeds the TTHM or HAAS MCL, include the
locational running annual averages for all locations that exceed the MCL (example
table provided in Appendix B).
- If you conducted sampling for the Initial Distribution System Evaluation (IDSE)
under the Stage 2 DBPR, during the calendar years that the water system collected
samples for the IDSE, systems must include IDSE sample results when reporting the
range of TTHM and HAAS but not the average.
d) For turbidity:
- For turbidity regulated as a MCL for systems that must install filtration but have not
(40 CFR 141.13), include the highest monthly average.
- For turbidity regulated as a TT for systems that have met criteria for avoiding
filtration (40 CFR 141.71), include the highest single measurement found in any
month. You should explain the reasons for measuring turbidity.
Preparing Your Drinking Water CCR 12 April 2010
-------
EXAMPLE-Turbidity is a measure of the cloudiness of the water. We monitor it
because it is a good indicator of water quality. High turbidity can hinder the
effectiveness of disinfectants.
For turbidity regulated as a TT for systems that filter, include the highest single
measurement and the lowest monthly percentage of samples meeting the turbidity
limits specified in 40 CFR 141.73, §141.173, or §141.551 for the relevant filtration
technology (example table provided in Appendix B). You should also explain the
reasons for measuring turbidity.
EXAMPLE-Turbidity is a measure of the cloudiness of the water. We monitor it
because it is a good indicator of the effectiveness of our filtration system.
e) For lead and/or copper:
- Include the 90th percentile value from the most recent sampling (if it is a number
greater than zero) and the number of sites that exceeded the action level (do not report
related water quality parameter data) (example table provided in Appendix B).
f) For total coliforms, fecal coliforms and E. coli under the Total Coliform Rule (TCR):
- For systems that collect fewer than 40 samples per month, include the highest number
of positive samples collected in any one month (example table provided in Appendix
B).
- For systems that collect 40 or more samples per month, include the highest
percentage of positive samples collected in any one month (example table provided in
Appendix B).
- For fecal coliforms and E. coli, include the number of positive samples collected that
year.
g) For fecal indicator-positive source samples under the GWR:
- For E. coli, list the MCL and MCLG as zero.
- For enterococci or coliphage, list "TT" in the column for MCL and "N/A" in the
column for MCLG.
- For all fecal indicator-positive ground water source samples (E. coli, enterococci, or
coliphage), include the total number of positive samples for the year and special
notice language provided in the table or elsewhere in the CCR. Refer to Item 6 for
more information on special notice language requirements for fecal indicator-positive
ground water source samples.
Preparing Your Drinking Water CCR 13 April 2010
-------
h) In addition to detected contaminants, the CCR Rule requires that all violations of
treatment techniques be reported in a detected contaminant table(s). TT violations are
listed below and are organized by rule (refer to Item 6 for specific information about
failure to install adequate filtration or disinfection equipment or processes or a failure of
those processes, violations associated with acrylamide and epichlorohydrin, and
violations associated with LCR).

Failure to take corrective action, if necessary based on a fecal indicator-positive
sample.
Failure to take corrective action, if necessary based on a significant deficiency.
EPA recommends that systems include TT violations listed in (h) above in a table
adjacent to the main detected contaminant table. The table must include an explanation of
the violation, the length of the violation, any potential adverse health effects, and steps
taken to correct the violation. The following is an example (see Appendix B for
additional examples).
Preparing Your Drinking Water CCR 15 April 2010
-------
TT Violation
Failed to
maintain 4-log
treatment of
viruses
Explanation
On January 10,2011,
state inspection of our
water system identified
a malfunctioning
chlorine pump. As a
result, the water from
one of our wells (Well
1) was not adequately
disinfected for 2 weeks.
Length
2 Weeks
Steps Taken to Correct the
Violation
As directed by the Department
of Public Health, we took
immediate action to resolve this
problem by repairing the
malfunctioning chlorine pump.
Regular testing since the pump
was repaired has demonstrated
that we are once again
providing water that meets the
state's standards for
disinfection to our customers.
Health Effects
Language
Inadequately treated or
inadequately protected
water may contain
disease-causing
organisms. These
organisms can cause
symptoms such as
diarrhea, nausea,
cramps, and associated
headaches.
i) If you detect beta particles in your water at or below 50 picocuries per liter (pCi/L), you
should report the detected level in pCi/L. So that consumers may have a standard against
which to compare that detected level, you should include "50 pCi/L*" in the MCL
column (rather than the actual MCL of 4 mrem/year) and include a footnote to the table
that says, "*EPA considers 50 pCi/L to be the level of concern for beta particles." If you
detect beta particles above 50 pCi/L, you must determine the actual radioactive
constituents present in the water to calculate the dose exposure level in mrem/year, and
must report both the detected level and MCL as mrem/year (example table provided in
Appendix B).
j) The likely source of the contaminant, to the best of your knowledge. If the source of
contamination is known, the CCR should identify a specific point source, such as "Al's
chicken houses" or the "Super-shiny Paper Mill." If you lack reliable information on the
specific source of a contaminant, include one or more of the typical sources listed in the
table in Appendix A to Subpart O (available on the EPA Web site at
www.epa.gov/safewater/ccr/regulations.html and in Appendix F of this document) that is
most applicable to your situation.
k) Clear highlighting of any contaminant detected in violation of a MCL, MRDL or TT, or
exceeding an AL. This indication could, for example, take the form of a different color
type, a larger or bolder font, or a large star. Near, but not in the table, include an
explanation of the length of the violation/exceedance, the potential adverse health effects,
and actions you took to address the violation/exceedance. Refer to the table in Appendix
A to Subpart O (available on the EPA Web site at
www.epa.gov/safewater/ccr/regulations.html and in Appendix F of this document) for
health effects language.
1) The average of all of the year's monitoring results and the range of detections for any
detected unregulated contaminants for which state or federal rules require monitoring (40
Preparing Your Drinking Water CCR
16
April 2010
-------
CFR 141.40). The list of unregulated contaminants applicable for monitoring during 2008
through 2010 under the Unregulated Contaminant Monitoring Rule is located on the EPA
Web site at www.epa.gov/safewater/ccr/regulations.html.
- You may wish to explain the reasons for unregulated contaminant monitoring with a
statement such as:
EXAMPLE-Unregulated contaminant monitoring helps EPA to determine where certain
contaminants occur and whether the Agency should consider regulating those contaminants
in the future.
Multiple Distribution Systems
If your system supplies water through two or more distribution systems that are not physically
interconnected and that are fed by different raw water sources, you must issue a CCR that
includes information on the source water, the levels of any detected contaminants, and
compliance with drinking water rules for all distribution systems. You may issue one or multiple
reports to your customers. If you issue one report, make sure to include a separate column of
detection data for each service area in the main table of detected contaminants.
Including Tier 3 Public Notices in CCRs
If you are required to provide Tier 3 public notice for a monitoring violation or other type of
violation or situation, you may consider including the notice in your CCR. If you use the CCR
for public notification, make sure you meet the content requirements under the Public
Notification Rule. Also, remember that the timing and delivery requirements for CCRs differ
from those for public notices. Be careful to adhere to the Public Notification requirement that
Tier 3 public notice be completed no later than 12 months from the date the violation or situation
occurred. To minimize the timing conflict, you can publish the CCR early-as soon after the end
of the calendar year as possible; or mail a separate public notice for the violations occurring in
January through June of the current year in the same envelope as your CCR covering the
previous calendar year's violations.
Item 5: Information on Monitoring for Cryptosporidium, Radon, and
Other Contaminants
Reporting on Cryptosporidium
If your system has performed monitoring that indicates the presence of Cryptosporidium in either
its source water or its finished water, you must include the detected results in your CCR. It is
recommended that you distinguish whether the data are linked to samples collected at the source
or samples collected in the finished water by putting the results on different lines in the table. If
Preparing Your Drinking Water CCR 17 April 2010
-------
the results of your monitoring indicated the presence of Cryptosporidium, you must include the
following information separate from the detected contaminant table:
A summary of the results of the monitoring. You may choose whether or not to report the
actual analytical results as a part of this summary.
An explanation of the significance of the results. Tell customers if they need to be
concerned by the information that the CCR provides.
EXAMPLE-Cryptosporidium is a microbial pathogen found in surface water throughout the
U.S. Although filtration removes Cryptosporidium, the most commonly-used filtration
methods cannot guarantee 100 percent removal Our monitoring indicates the presence of
these organisms in our source water and/or finished water. Current test methods do not
allow us to determine if the organisms are dead or if they are capable of causing disease.
Ingestion of Cryptosporidium may cause cryptosporidiosis, an abdominal infection.
Symptoms of infection include nausea, diarrhea, and abdominal cramps. Most healthy
individuals can overcome the disease within a few weeks. However, immuno-compromised
people, infants and small children, and the elderly are at greater risk of developing life-
threatening illness. We encourage immuno-compromised individuals to consult their doctor
regarding appropriate precautions to take to avoid infection. Cryptosporidium must be
ingested to cause disease, and it may be spread through means other than drinking water.
Reporting on Radon
If your system has performed monitoring that indicates the presence of radon in its finished
water, you must include in your CCR:
The results of monitoring (the analytical values reported by the laboratory).
An explanation of the significance of the results. Tell customers if they need to be
concerned by the information that the CCR provides.
Preparing Your Drinking Water CCR 18 April 2010
-------
EXAMPLERadon is a radioactive gas that you cannot see, taste, or smell. It is found
throughout the U.S. Radon can move up through the ground and into a home through cracks
and holes in the foundation. Radon can build up to high levels in all types of homes. Radon
can also get into indoor air when released from tap water from showering, washing dishes,
and other household activities. Compared to radon entering the home through soil, radon
entering the home through tap water will in most cases be a small source of radon in indoor
air. Radon is a known human carcinogen. Breathing air containing radon can lead to lung
cancer. Drinking water containing radon may also cause increased risk of stomach cancer.
If you are concerned about radon in your home, test the air in your home. Testing is
inexpensive and easy. (You should pursue radon removal for your home if the level of radon
in your air is 4 picocuries per liter of air (pd/L) or higher. There are simple ways to fix a
radon problem that are not too costly. For additional information, call your state radon
program or call EPA 's Radon Hotline (800-SOS-RADON).
Reporting on Additional Monitoring
If your system has performed voluntary monitoring that indicates the presence of contaminants
that you were not required to monitor for in your finished water, EPA strongly encourages you to
report any results that may indicate a health concern. Public knowledge of potential problems is
in your interest as well as your customers'. EPA considers any detection above a proposed MCL
or health advisory level to indicate concern. Call the Safe Drinking Water Hotline or visit EPA's
Web site for this information. For these contaminants, EPA recommends that the CCR contain:
The results of monitoring.
An explanation of the significance of the results, noting the existence of the health
advisory or proposed MCL.
Item 6: Compliance with Other Drinking Water Regulations
National Primary Drinking Water Regulation (NPDWR) Violations
If your water system violated one of the following requirements during the year covered by your
CCR, you must describe the violation(s) in your CCR. Just as you must explain the potential
health effects of any MCL violation, you must provide a clear and readily understandable
explanation of any other violation, potential adverse health effects (if any), and the steps the
system has taken to correct the violation. For health effects language, refer to the table in
Appendix A to Subpart O on EPA's Web site at www.epa.gov/safewater/ccr/regulations.html or
in Appendix F of this document.
Preparing Your Drinking Water CCR 19 April 2010
-------
1) Treatment techni que s.
Filtration and disinfection requirements contained in the SWTR. If the violation was a
failure to install adequate filtration or disinfection equipment or processes, or there was a
failure of that equipment or process, include the following language:
Inadequately treated water may contain disease-causing organisms. These organisms
include bacteria, viruses, and parasites, which can cause symptoms such as nausea, cramps,
diarrhea, and associated headaches.
Lead and copper control requirements. If the violation was a failure to meet corrosion
control treatment, source water treatment, or lead service line requirements, include the
health effects language for lead or copper from Appendix A to Subpart O.
Acrylamide and Epichlorohydrin. If you violate either treatment technique, you must
include the relevant health effects language from Appendix A to Subpart O.
Note: EPA recommends that systems include TT violations listed here in a table adjacent to
the main detected contaminant table. See Item 4 for more discussion on presenting TT
violations.
2) Monitoring and reporting of compliance data. If your system failed to take a sample on time
(i.e., failure to monitor), the CCR should say "health effects unknown." If your system took
the samples accurately and on time, but mailed the results late, you do not need to discuss
health effects.
3) Record keeping requirements.
4) Special monitoring requirements.
5) Violation of a variance, an exemption, or an administrative or judicial order.
Special Notice for Systems Required to Comply with the GWR
The GWR requires that you provide special notice in their CCRs for the following two
situations:
Preparing Your Drinking Water CCR 20 April 2010
-------
Special Notice for Uncorrected Significant Deficiencies1
If you are a ground water system that receives notice from the state of a significant
deficiency, you must inform your customers of any significant deficiencies that are not
corrected by December 31 of the year covered by your CCR. The CCR must include the
following information:
The nature of the significant deficiency and the date it was identified by the state.
The state-approved plan and schedule for correction, including interim measures,
progress to date, and any interim measures completed.
You must continue to inform your customers annually until the state determines the
significant deficiency is corrected.
Note: The state may also require you to include in your CCR significant deficiencies that
were corrected by the end of the calendar year. If you are directed by your state to do this,
you must inform your customers of the significant deficiency, how it was corrected, and
the date it was corrected in that year's CCR.
Special Notice for a Fecal Indicator-Positive Ground Water Source Sample
If you are a ground water system that receives notice from a laboratory of a fecal
indicator-positive ground water source sample and the sample is not invalidated by the
state, you must inform your customers in the next CCR. The CCR must include the
following information for a fecal indicator-positive ground water source sample:
The source of the fecal contamination (if it is known) and the date(s) of the fecal
indicator-positive source sample.
If the fecal contamination has been addressed as prescribed by the requirements of the
GWR and the date the contamination was addressed.
For fecal contamination that has not been addressed, the state-approved plan and
schedule for correction, including interim measures, progress to date, and any interim
measures completed.
1 Significant Deficiency: A deficiency that may cause, or have the potential to cause the introduction of
contamination into finished water. An example of a significant deficiency is an unscreened vent on a storage tank
that uncorrected may allow water, dirt, waste or other contaminants to enter the tank.
Preparing Your Drinking Water CCR 21 April 2010
-------
The health effects language for fecal indicators. Refer to Appendix A to Subpart O of
the Rule for health effects language (available on the EPA Web site at
www.epa.gov/safewater/ccr/regulations.html or in Appendix F of this document).
Since fecal indicator-positive ground water source samples must be included in the
detected contaminant table, this special notice language can be included below the table or
elsewhere in the report. Appendix B of this guidance contains an example on how to
present fecal indicator-positive ground water source samples and the special notice text in
aCCR.
You must continue to inform customers annually until the fecal contamination in the
ground water source is addressed as prescribed by the requirements of the GWR.
Item 7: Variances and Exemptions
If your system operated under a variance or exemption at any time during the year covered by
the CCR, include an explanation of the justification for the variance or exemption, the date that it
was issued, when it is up for renewal, and a status report on what the system is doing to remedy
the problem. Also, tell your customers how they may participate in the review or renewal of the
variance or exemption.
Item 8: Required Educational Information
Every CCR must contain certain educational information, prominently displayed somewhere in
the report.
The following statement is a brief explanation regarding contaminants that may reasonably be
expected to be found in drinking water, including bottled water.
Drinking water, including bottled water, may reasonably be expected to contain at least
small amounts of some contaminants. The presence of contaminants does not necessarily
indicate that water poses a health risk. More information about contaminants and potential
health effects can be obtained by calling the EPA 's Safe Drinking Water Hotline (1-800-426-
4791).
The next statement informs customers that some people may be more vulnerable to contaminants
in drinking water than the general population and encourages those who may be particularly at
risk from infection to seek advice from their health care provider.
Preparing Your Drinking Water CCR 22 April 2010
-------
Some people may be more vulnerable to contaminants in drinking water than the general
population. Immuno-compromised persons such as persons with cancer undergoing
chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or
other immune system disorders, some elderly, and infants can be particularly at risk from
infections. These people should seek advice about drinking water from their health care
providers. EPA/CDC guidelines on appropriate means to lessen the risk of infection by
Cryptosporidium and other microbial contaminants are available from the Safe Drinking
Water Hotline (1-800-426-4791).
Your CCR must contain basic information about drinking water contaminants. Use the following
language, or you may write your own comparable language that better fits your specific local
situation:
The sources of drinking water (both tap water and bottled water) include rivers, lakes,
streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the
land or through the ground, it dissolves naturally-occurring minerals and, in some
cases, radioactive material, and can pick up substances resulting from the presence of
animals or from human activity.
Contaminants that may be present in source water include:
Microbial contaminants, such as viruses and bacteria, which may come from
sewage treatment plants, septic systems, agricultural livestock operations, and
wildlife.
Inorganic contaminants, such as salts and metals, which can be naturally-
occurring or result from urban stormwater runoff, industrial or domestic
wastewater discharges, oil and gas production, mining, or farming.
Pesticides and herbicides, which may come from a variety of sources such as
agriculture, urban stormwater runoff, and residential uses.
Organic chemical contaminants, including synthetic and volatile organic
chemicals, which are byproducts of industrial processes and petroleum
production, andean also come from gas stations, urban stormwater runoff,
and septic systems.
Radioactive contaminants, which can be naturally-occurring or be the result
of oil and gas production and mining activities.
Preparing Your Drinking Water CCR 23 April 2010
-------
In order to ensure that tap water is safe to drink, EPA prescribes regulations which
limit the amount of certain contaminants in water provided by public water systems.
Food and Drug Administration regulations establish limits for contaminants in bottled
water which must provide the same protection for public health.
Special Requirements for Nitrate, Arsenic, and Lead
You must include in your CCR the relevant special educational statement for nitrate, arsenic, and
lead in the specified situations. If you would like to write your own educational statement or alter
the statement provided in the regulations, you must consult with your state.
Nitrate: Systems with nitrate above 5 ppm (50 percent of the MCL), but below 10 ppm
(the MCL) must include the following statement:
Nitrate in drinking water at levels above 10 ppm is a health risk for infants of less than six
months of age. High nitrate levels in drinking water can cause blue baby syndrome. Nitrate
levels may rise quickly for short periods of time because of rainfall or agricultural activity.
If you are caring for an infant, you should ask for advice from your health care provider.
Arsenic: Systems with arsenic above 5 ppb (50 percent of the MCL), but at or below 10
ppb (the MCL) must include the following statement:
While your drinking water meets EPA 's standard for arsenic, it does contain low levels of
arsenic. EPA 's standard balances the current understanding of arsenic's possible health
effects against the costs of removing arsenic from drinking water. EPA continues to research
the health effects of low levels of arsenic, which is a mineral known to cause cancer in
humans at high concentrations and is linked to other health effects such as skin damage and
circulatory problems.
Preparing Your Drinking Water CCR 24 April 2010
-------
Lead: All systems must include the following informational statement:
If present, elevated levels of lead can cause serious health problems, especially for pregnant
women and young children. Lead in drinking water is primarily from materials and
components associated with service lines and home plumbing. [NAME OF UTILITY] is
responsible for providing high quality drinking water, but cannot control the variety of
materials used in plumbing components. When your water has been sitting for several hours,
you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2
minutes before using water for drinking or cooking. If you are concerned about lead in your
water, you may wish to have your water tested. Information on lead in drinking water,
testing methods, and steps you can take to minimize exposure is available from the Safe
Drinking Water Hotline or at www. epa. gov/safewater/lead.
Other Educational Information
You are not limited to providing only the required information in your CCR. You may want to
include:
An explanation (or include a diagram of) your system's treatment processes.
Source water protection tips (refer to Appendix D, Table D-3 for example language
regarding source water protection tips).
Water and energy conservation tips (refer to Appendix D, Table D-3 for example
language regarding water conservation tips).
The cost of making the water safe to drink including the cost of sustaining the
infrastructure.
Efforts your system has made to promote "green infrastructure" (e.g., stormwater
pollution prevention measures).
A statement from the mayor or general manager.
Information to educate customers about: taste and odor issues, affiliations with programs
such as the Partnership for Safe Water, opportunities for public participation, etc.
You may want to provide the address for EPA's drinking water Web site
(www.epa.gov/safewater). The only limitation on this information is that it must not interfere
with the educational purpose of the CCR.
Preparing Your Drinking Water CCR 25 April 2010
-------
V. What should the CCR look like?
You do not need a fancy computer or a graphic designer to produce a CCR that is easy to read
and inviting to your customers. The best way to design your CCR is to spend some time looking
at other CCRs. See what catches your eye, and copy it. A few things to consider:
Limit wordiness - write short sentences and keep your paragraphs short as well.
Do not make your text size too small. You might want to squeeze a few extra sentences in
your CCR, but if you add too much, people might ignore the entire report.
Give a draft of your CCR to relatives or friends who are not drinking water experts and
ask them if it makes sense. Ask customers for their comments when you publish the
CCR.
Do not distract from your main message with graphics and/or pictures that do not
complement your message.
Be as simple, truthful, and straight forward as possible. Avoid acronyms, initials, and
jargon.
Consider printing the CCR on recycled paper and taking other steps to make the CCR
"environmentally friendly." If you hope to get your customers involved in protecting
source water, set a good example for them.
Use the CCR as an opportunity to tell your customers about all of the things that you are
doing well.
VI. How must the CCR be distributed?
You must mail or deliver a copy of your CCR to each of your customers, and make a good faith
effort to get CCRs to non-bill-paying consumers. Deliver your CCR by July 1 of each year. You
may include your CCR with water bills, if feasible, or you may send it as a separate mailer.
Sending your CCR as a separate mailer will likely be more effective, and you will reach renters
who may not receive water bills directly.
Send a copy to the director of the state drinking water program and any other state agency that
the state drinking water program director identifies when you mail it to customers. Within three
months of the CCR's due date, submit to the state a certification (see Appendix C) that you
distributed the CCR, and that its information is correct and consistent with the compliance
monitoring data previously submitted to the state. EPA also encourages you to send copies to
state and local health departments, as well as local TV and radio stations and newspapers.
Systems that serve 100,000 or more people must post their CCRs on the Internet. EPA
encourages other systems to use this option as well. Many local governments have sites where
Preparing Your Drinking Water CCR 26 April 2010
-------
you can post your CCR, even if your system itself does not have a Web site. EPA provides a
mechanism that allows systems to link their CCR to the EPA Web site
(www.epa.gov/safewater/ccr/compliancehelp.html). You must also make your CCR available to
the public upon request.
Reach All Consumers Not Receiving Water Bills
It is in your system's interest to spread the word about the quality of its drinking water. Since
many consumers of your water may not receive bills (people such as apartment renters) you must
make serious and "good faith" efforts to reach non-bill paying consumers. A "good faith" effort
means selecting the most appropriate method(s) to reach those consumers from a menu of
options that your state recommends. Those options include but are not limited to:
Posting the CCR on the Internet using Web sites, email notifications, Podcasts, blogs, or
Tweets.
Mailing the CCR to all postal patrons.
Advertising the availability of the CCR in newspapers, TV, and radio.
Publishing the complete CCR in a local newspaper.
Posting the CCR in public places such as cafeterias and lobbies of public buildings,
libraries, churches, and schools.
Delivering multiple CCRs for distribution by single-biller customers such as apartment
buildings or large private employers.
Delivering the CCR to community organizations.
Waiving the Mailing Requirement
Your Governor (or Tribal leader or EPA Regional Administrator, if applicable) can waive the
mailing requirement for water systems that serve fewer that 10,000 people. You may choose to
mail the CCR even if the Governor has issued a waiver. If you decide to use the waiver, take the
following steps:
Publish the CCR in one or more local newspapers.
Inform customers, by notification in newspapers or by other means approved by the state,
that CCRs will not be mailed.
Make the CCRs available upon request.
Preparing Your Drinking Water CCR 27 April 2010
-------
For specific subpopulations in your community, you may wish to distribute CCRs to
organizations specific to those groups.
If your system serves 500 or fewer people and the Governor waives the mailing requirement for
small systems, you do not have to publish the CCR in the newspaper, though you may want to do
so. At least once a year, you must notify customers through a mailed, delivered, or posted notice
that the CCR is available from your water system upon request.
VII. Keeping CCR Copies on File
You must keep copies of your CCRs on file for a minimum of three years.

Example that demonstrates reporting TCR detects with no MCL violation:
Detects of coliform, fecal coliform or E. coli bacteria during routine monitoring must be
reported, even if no MCL violation occurred.
For a system that collects at least 40 samples per month (i.e., a system that serves >
33,000 people), if no more than 5.0 percent of the samples collected during a month are
positive, the system is in compliance with the MCL for total coliforms.
For a system that collects fewer than 40 samples/month (i.e., a system serving < 33,000
people), if no more than one sample collected during a month is positive, the system is in
compliance with the MCL for total coliforms.
In these situations, you may wish to report detects as shown below. Check with your state
to make sure this meets state-specific requirements.

Example that demonstrates TOC reporting (surface water treatment plants with
conventional treatment or precipitative softening)
If any of the following apply, you must report a treatment technique violation for
enhanced coagulation or enhanced softening (if applicable):
- Alternate compliance criteria for enhanced coagulation or enhanced softening
cannot be met.
- Quarterly TOC monitoring does not demonstrate the percentage removal of TOC
(demonstrated in the table below).
- A system does not obtain state approval for alternate minimum TOC removal
(Step 2) requirements.
The example CCR Table excerpt below is for a conventional surface water treatment
system with source water TOC between 2-4 mg/L and with a source water alkalinity
between 0-50 mg/L. It demonstrates how to report this TOC TT violation:
TT Violation
Failure to
remove
required
amount of
total organic
carbon (TOC)
(DBPP)
Explanation of the
TT Violation
On March 3rd, we
collected samples
for TOC before and
after our treatment
process to determine
the percentage of
TOC we were
removing. Results
showed that we were
removing 25 percent
of the TOC. We are
required to remove
35 percent of the
TOC.
Length of
the
Violation
1 month
Steps Taken to
Correct the
Violation
We examined our
treatment processes
to see if we could
improve our removal
of TOC. We made
some adjustments to
our process on
March 29th. Samples
collected after that
time show that we
are able to achieve
35 percent removal.
Health Effect Language
Total organic carbon (TOC)
has no health effects. However,
total organic carbon provides a
medium for the formation of
disinfection byproducts. These
byproducts include
trihalomethanes (THMs) and
haloacetic acids (HAAs).
Drinking water containing
these byproducts in excess of
the MCL may lead to adverse
health effects, liver, or kidney
problems, or nervous system
effects, and may lead to an
increased risk of getting cancer.

Example that demonstrates reporting beta particles results
The MCL for beta particles is 4 mrem/year. EPA recognizes that laboratories often report
these results in pCi/L, and that there is no simple conversion between the two units.
Therefore, it is acceptable for systems to report the detected level for beta particles in
pCi/L. So that consumers may have a standard against which to compare the detected
level, systems should place 50 in the MCL column and include a footnote explaining that
EPA considers 50 pCi/L to be a level of concern for beta particles.

Examples that demonstrates treatment technique violation reporting under
LT2ESWTR
For violations of treatment techniques under LT2ESWTR, the system must provide an
explanation of the violation, an indication of the length of the violation, information on
steps taken to correct the violation, and health effects language. Because there are no
standard health effects language provided for these treatment techniques, the system
would have to write language specific to the violation. You can use the health effect
language for contaminants as an example or template.

occurred in the same year):

may remember receiving public notification of this violation on December 10. For reasons discussed in
the next paragraph, we took Well 1 off-line on December 11. The duration of the violation was two
days. We are addressing this contaminated well as discussed below.
** On December 10, 2009, we sampled the sources (Well 1 and Well 2) for the fecal-indicator, E. coli.
We were notified on December 11 that Well 1 tested positive for E. coli. On December 12, we took five
additional samples and were notified on December 13 that two of the five samples were positive for E.
coli. We immediately took Well 1 off-line at that time. Our system is in contact with the state DEQ, and
we have a state-approved plan to abandon this well and replace it with a new well. We will have the
new well completed by July 5, 2010, and the old well will be abandoned by July 15, 2010. As an interim
measure, we have moved to only utilizing this well as an emergency source and have not had to utilize it
since the sampling revealed the contamination.
Health Effects: Fecal coliforms and E. coli are bacteria whose presence indicates that the water may be
contaminated with human or animal wastes. Microbes in these wastes can cause short-term effects, such
as diarrhea, cramps, nausea, headaches, or other symptoms. They may pose a special health risk for
infants, young children, some of the elderly, and people with severely compromised immune systems.

Appendix D - Information on Source Water Assessment
Programs and Conservation Efforts
Appendix D provides more detailed information on state Source Water Assessment Programs
(SWAPs), Wellhead Protection Programs (WHPs), and incorporating source water assessment
results and source water protection and conservation tips into your CCR.
Source Water Assessment Program
Background
The 1996 amendments to the Safe Drinking Water Act (SDWA) included a focus on pollution
prevention, which complements the traditional treatment approach to ensuring safe drinking
water. In Section 1453, the amendments required states to develop Source Water Assessment
Programs (SWAPs) and submit them for EPA approval by February of 1999. EPA reviewed and
approved these programs and states subsequently completed source water assessments for all
public water systems (PWS). These assessments included a delineation of a source water
protection area, an inventory of potentially significant sources of contamination, and a
determination of the susceptibility of the PWS to these potential contamination sources.
As part of an approved program, states must make the results of these assessments available to
the public - either directly or through a delegated entity. This last requirement can, in part, be
met through the requirements of the CCR Rule that water systems provide susceptibility
determinations to the public once an assessment has been completed. Although information
about source water protection efforts is not specifically required in CCRs, the reports offer an
excellent opportunity for water systems to explain how a community's drinking water supply is
being protected.
In addition to SWAPs, many systems conducted developed and implemented Wellhead
Protection Programs (WHPs) to satisfy or go beyond the SWAP assessment requirements.
Wellhead programs are either voluntary or mandatory for water systems depending on the states'
program, but do include development of wellhead management plans. Most states have
integrated SWAP and WHP activities. One of the key distinctions between the SWAPs and
existing wellhead programs and watershed protection programs is that SWAPs explicitly include
a determination about the susceptibility of the drinking water system to sources of
contamination. These determinations are useful for the purposes of CCR reporting since the CCR
Rule requires that reports contain a brief summary of the results of these susceptibility
determinations.
More information about state SWAP programs, including a list of state source water contacts and
links to state source water Web sites can be found through www.epa.gov/safewater.

Incorporating Source Water Assessment Results in CCRs
Information about source water is an important part of the CCR. Table D-l is a list of the report
requirements related to source water.
Table D-1. CCR Requirements Referencing Source Water Assessment Results
Rule/ Guidance
Citation
Requirement
40CFR141.153(b)(l)
Each report must identify the source(s) of water delivered by the
COMMUNITY WATER SYSTEM by providing information on: the type of
water used (i.e., surface water or ground water), the commonly used name (if
any) and the location of the body (or bodies) of water.
40CFR141.153(b)(2)
For completed source water assessments, the CCR must:
1) Notify consumers that this information is available.
2) Tell the consumers how to obtain the information.
Where a system has received a source water assessment from the state, the
report must include a brief summary of the system's susceptibility to potential
sources of contamination, using language provided by the state or written by
the operator.
Systems are also encouraged to report significant sources of contamination in
the source area if they have readily available information.
40CFR141.153
Each report must include the likely source(s) of detected contaminants to the
best of the operator's knowledge. Specific information regarding the likely
source (s) of the contaminants may be available in sanitary surveys and source
water assessments and should be used when available to the operator. If the
operator lacks specific information on the likely source(s), the report must
include one or more typical sources given in the Appendix A to Subpart O.
(See Appendix F of this guidance for the list of typical sources).
40CFR141.153(e)(l)
If a system has performed any monitoring which indicate that
Cryptosporidium may be present in the raw or finished water, the report must
include a summary of the results of the monitoring and an explanation of the
significance of the results.
40CFR141.153(h)(l)
Every CCR must contain a brief explanation about the sources of drinking
water and contaminants that may be present in the source water. Systems can
either use the language provided in 40 CFR 141.153(h)(l)(i), (ii), and (iii) or
develop comparable language.

Ground water source
Source water
assessment
available
Our water comes from three wells drilled about 500 feet into an underground
source of water called the Low Plains Aquifer. These wells are located west
of town on the north side of City Park. The wellhead protection area for
these wells extends approximately 2000 feet north, 4000 ft south and 1500 ft
east and west of the well field. (Please see the map). We have a town
ordinance that prohibits dumping and many other activities that could pollute
our drinking water in this wellhead area. The Department of Environmental
Resources (DER) completed an assessment of our source water in January of
2001 and has reported that our raw water is most susceptible to
contamination from abandoned irrigation wells and farm runoff. The town
has done a follow-up investigation and has identified two abandoned wells.
They have been properly plugged. Farm runoff continues to be a concern.
Please contact the County Extension Service at [phone number] to get a list
of area farmers participating in a three county source water protection
program. You can get a summary of our assessment by calling the DER
Region 1 office at [phone number]. A full copy of the assessment is available
in the town clerk's office or on the Internet [Internet address].
Surface Water
Source water

Cryptosporidium
detected
Our utility serves you treated surface water which is taken from the
Grubstake river near Spitfire Junction. We collect it in the McErtel Reservoir
and then pipe it to the treatment plant just northwest of town. The state
drinking water program through a source water assessment report has found
that our drinking water is potentially most susceptible to farm runoff as well
as three underground storage tanks in Spitfire county. However, we have not
detected any contaminants from these sources in our drinking water. You can
get a copy of the source water assessment by calling the state drinking water
program at [phone number].
In 2010, we monitored for Cryptosporidium, a microbial parasite commonly
found in surface water, and found some evidence of these microbes in the
raw, but not the finished water. Current test methods do not enable us to
determine if these organisms are capable of causing disease. We are not
aware of a specific source of Cryptosporidium. Cryptosporidium may come
from wildlife or cattle grazing near the reservoir. Cryptosporidium must be
ingested for it to cause disease, and may be passed through other means than
drinking water. Symptoms of infection include nausea, diarrhea, and

abdominal cramps. These symptoms can also be the result of food related
organisms or flu or ingesting untreated water. Most healthy individuals are
able to overcome the disease within a few weeks. However, some people
may be more vulnerable to contaminants in drinking water than the general
population. Immuno-compromised people, such as persons with cancer
undergoing chemotherapy, persons who have undergone organ transplants,
people living with HIV/AIDS or other immune system disorders, some
elderly, and infants can be particularly at risk. These people should seek
advice from their health care providers. EPA/CDC guidelines on appropriate
means to lessen the risk of infection by Cryptosporidium and other microbial
contaminants are available from the Safe Drinking Water Hotline (1-800-
426-4791).

Source Water
Protection Tips for
Consumers
Protection of drinking water is everyone's responsibility. You can help protect
your community's drinking water source in several ways:
Eliminate excess use of lawn and garden fertilizers and pesticides - they
contain hazardous chemicals that can reach your drinking water source.
Pick up after your pets.
If you have your own septic system, properly maintain your system to reduce
leaching to water sources or consider connecting to a public water system.
Dispose of chemicals properly; take used motor oil to a recycling center.
Volunteer in your community. Find a watershed or wellhead protection
organization in your community and volunteer to help. If there are no active
groups, consider starting one. Use EPA's Adopt Your Watershed to locate
groups in your community, or visit the Watershed Information Network's
How to Start a Watershed Team.
Organize a storm drain stenciling project with your local government or
water supplier. Stencil a message next to the street drain reminding people
"Dump No Waste - Drains to River" or "Protect Your Water". Produce and
distribute a flyer for households to remind residents that storm drains dump
directly into your local water body.

Water Conservation
Tips for Consumers
Did you know that the average U.S. household uses approximately 400 gallons of
water per day or 100 gallons per person per day? Luckily, there are many low-cost
and no-cost ways to conserve water. Small changes can make a big difference - try
one today and soon it will become second nature.
Take short showers - a 5 minute shower uses 4 to 5 gallons of water
compared to up to 50 gallons for a bath.
Shut off water while brushing your teeth, washing your hair and shaving and
save up to 500 gallons a month.
Use a water-efficient showerhead. They are inexpensive, easy to install, and
can save you up to 750 gallons a month.
Run your clothes washer and dishwasher only when they are full. You can
save up to 1,000 gallons a month.
Water plants only when necessary.
Fix leaky toilets and faucets. Faucet washers are inexpensive and take only a
few minutes to replace. To check your toilet for a leak, place a few drops of
food coloring in the tank and wait. If it seeps into the toilet bowl without
flushing, you have a leak. Fixing it or replacing it with a new, more efficient
model can save up to 1,000 gallons a month.
Adjust sprinklers so only your lawn is watered. Apply water only as fast as
the soil can absorb it and during the cooler parts of the day to reduce
evaporation.
Teach your kids about water conservation to ensure a future generation that
uses water wisely. Make it a family effort to reduce next month's water bill!

Appendix E - Examples of Consumer Confidence Reports
EPA is providing the following CCRs as examples of report format. In providing these reports,
EPA is not endorsing the views nor judging the accuracy of the information contained in the
reports. These examples do not necessarily meet all current federal and state CCR requirements.
Be sure to check with your state drinking water program since your state may have different
requirements from those under which these reports were created. For assistance creating a CCR,
systems can access the EPA CCR/Writer tool (www.ccriwriter.com).
The first report, Sampletown Annual Water Quality Report, is fictitious and was created
as a general example.
The second report, Miami-Dade Water & Sewer Department, 2008 Water Quality Report
is another example of a large surface water system, but is a good example of a bilingual
report.
The third report, Water Quality - Treatment, Sampling, Monitoring - Department of
Public Works, Helena Water Treatment Division, 2009 Consumer Confidence Water
Quality Report, is an example of a smaller surface water system. The system provides
water to the City of Helena, Montana and does not sell water to any other public water
system.

Is my water safe?
Last year, we conducted tests for over 80 contaminants. We only detected 10 of those
contaminants, and found only 1 at a level higher than the Environmental Protection Agency
(EPA) allows. As we told you at the time, our water temporarily exceeded drinking water
standards. (For more information see the section labeled Violations and Exceedances at the end
of the report.) This report is a snapshot of last year's water quality. Included are details about
where your water comes from, what it contains, and how it compares to standards set by
regulatory agencies. We are committed to providing you with information because informed
customers are our best allies.
Do I need to take special precautions?
Some people may be more vulnerable to contaminants in drinking water than the general
population. Immuno-compromised persons such as persons with cancer undergoing
chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other
immune system disorders, some elderly, and infants can be particularly at risk from infections.
These people should seek advice about drinking water from their health care providers.
EPA/Centers for Disease Control (CDC) guidelines on appropriate means to lessen the risk of
infection by Cryptosporidium and other microbial contaminants are available from the Safe
Water Drinking Hotline (800-426-4791).
Where does my water come from?
Your water comes from three municipal wells sunk about 500 feet into an underground source of
water called the Low Plain Aquifer. These wells are located west of town. The town owns the
land around these wells and restricts any activity that may contaminate them. After the water
comes out of the wells, we treat it to remove several contaminants and we also add disinfectant
to protect you against microbial contaminants.
Preparing Your Drinking Water CCR 62 April 2010
-------
Source water assessment and its availability
The state performed an assessment of our source water in January of 2005. A source water
assessment identifies potential sources of contamination to the water we use for your drinking
water. The assessment concluded that our water source is most susceptible to contamination from
abandoned irrigation wells and farm runoff. Two abandoned wells have been located and have
since been properly plugged. Farm runoff continues to be a concern although many local farmers
are participating in a 3 county source water protection program. Please call us at 111-2233 if you
would like more information about the assessment.
Why are there contaminants in my drinking water?
Drinking water, including bottled water, may reasonably be expected to contain at least small
amounts of some contaminants. The presence of contaminants does not necessarily indicate that
water poses a health risk. More information about contaminants and potential health effects can
be obtained by calling the EPA's Safe Drinking Water Hotline (800-426-4791). The sources of
drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds,
reservoirs, springs, and wells. As water travels over the surface of the land or through the
ground, it dissolves naturally occurring minerals and, in some cases, radioactive material, and
can pick up substances resulting from the presence of animals or from human activity.
Contaminants that may be present include: Microbial contaminants, such as viruses and bacteria,
that may come from sewage treatment plants, septic systems, agricultural livestock operations,
and wildlife; inorganic contaminants, such as salts and metals, which can be naturally occurring
or result from urban stormwater runoff, industrial, or domestic wastewater discharges, oil and
gas production, mining, or farming; pesticides and herbicides, which may come from a variety of
sources such as agriculture, urban stormwater runoff, and residential uses; organic chemical
contaminants, including synthetic and volatile organic chemicals, which are by-products of
industrial processes and petroleum production, and can also come from gas stations, urban
stormwater runoff, and septic systems; and radioactive contaminants, which can be naturally
occurring or be the result of oil and gas production and mining activities. In order to ensure that
tap water is safe to drink, EPA prescribes regulations that limit the amount of certain
contaminants in water provided by public water systems. Food and Drug Administration (FDA)
regulations establish limits for contaminants in bottled water which must provide the same
protection for public health.
How can I get involved?
Our Water Board meets on the first Tuesday of each month at 7:30 pm at Edison High School on
Maple Lane. Please feel free to participate in these meetings. Your input is important to us!
Monitoring and reporting of compliance data violations
Our water system failed to conduct monitoring for Arsenic on time. We are required to sample
annually. Due to an oversight, we took the sample 3 months late. Although the late sample was
below the MCL we are uncertain whether or not there may be any adverse health risks associated
Preparing Your Drinking Water CCR 63 April 2010
-------
with this violation. We have recently implemented a new monitoring scheduling system which
should prevent this type of monitoring oversight in the future.
Additional information for Lead
If present, elevated levels of lead can cause serious health problems, especially for pregnant
women and young children. Lead in drinking water is primarily from materials and components
associated with service lines and home plumbing. Sampletown is responsible for providing high
quality drinking water, but cannot control the variety of materials used in plumbing components.
When your water has been sitting for several hours, you can minimize the potential for lead
exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or
cooking. If you are concerned about lead in your water, you may wish to have your water tested.
Information on lead in drinking water, testing methods, and steps you can take to minimize
exposure is available from the Safe Drinking Water Hotline or at www.epa.gov/safewater/lead.
Additional information for Nitrate
Nitrate in drinking water at levels above 10 ppm is a health risk for infants of less than six
months of age. High nitrate levels in drinking water can cause blue baby syndrome. Nitrate
levels may rise quickly for short periods of time because of rainfall or agricultural activity. If you
are caring for an infant, you should ask for advice from your health care provider.
Water Quality Data Table
The table below lists all of the drinking water contaminants we detected that are applicable for
the calendar year of this report. The presence of contaminants in the water does not necessarily
indicate that the water poses a health risk. Unless otherwise noted, the data presented in this table
is from testing done in the calendar year of the report. The EPA or the state requires us to
monitor for certain contaminants less than once per year because the concentrations of these
contaminants do not change.

Maximum Contaminant Level Goal: The level of a contaminant in drinking water below
which there is no known or expected risk to health. MCLGs allow for a margin of safety.
Maximum Contaminant Level: This highest level of a contaminant that is allowed in
drinking water. MCLs are set as close as feasible using the best available treatment
technology.
Treatment Technique: A required process intended to reduce the level of a contaminant in
drinking water.
Action Level: The concentration of a contaminant which, if exceeded, triggers treatment
or other requirements which a water systems must follow.
Maximum Residual Disinfectant Level Goal: The level of a drinking water disinfectant
below which there is no known or expected risk to health. MRDLGs do not reflect the
benefits of the use of disinfectants to control microbial contaminants.
Maximum Residual Disinfectant Level: The highest level of a disinfectant allowed in
drinking water. There is convincing evidence that addition of a disinfectant is necessary
for control of microbial contaminants.
Violations and Exceedances: Atrazine
Some people who drink water containing atrazine well in excess of the MCL over many years
could experience problems with their cardiovascular system or reproductive difficulties. During
March, April and May a surge in use of atrazine-based herbicides by area farmers caused our
water to exceed the MCL for atrazine. We sent a notice warning you of the problem when it

About Our Water, Where It Comes
From and How It's Treated
Miami-Dade's source of water is groundwater from wells. The wells
draw solely from the Biscayne Aquifer for a large part of WASD's
system. For customers served by the Alexander Orr, Jr. Water
Treatment Plant, the wells supplying this plant draw water mostly
from the Biscayne Aquifer and some water from the Floridan Aquifer.
In 2008 the Department of Environmental Protection performed a Source
Water Assessment on our system. The assessment was conducted to provide
information about any potential sources of contamination in the vicinity of our
wells. There are 92 potential sources of contamination identified for this system
with low to moderate susceptibility levels. The assessment results are available
on the FDEP Source Water Assessment and Protection Program website at
www.dep.state.fl.us/swapp.
How Our Water Is Treated
The Alexander Orr, Jr. Plant
Water from the Alexander Orr, Jr. plant receives lime
treatment to reduce hardness, and is then disinfected
and filtered. This plant supplies mostly water from the
Biscayne Aquifer blended with some water from the
Floridan Aquifer. The Alexander Orr, Jr. Plant serves
customers who live south of SW 8 Street to about SW
264 Street.
The Hialeah & John E. Preston Plants
Water from WASD's other two regional water treatment
plantsHialeah and John E. Prestoncomes solely
from the Biscayne Aquifer. Together with the Alexan-
der Orr, Jr. plant, all three plants supply treated water
to a common distribution system, running throughout
most of Miami-Dade County.
In general, the Hialeah and John E. Preston Plants
treat water that is supplied to residents who live north of
SW 8 Street up to the Miami-Dade/Broward Line.
Water from the Hialeah plant is treated similarly to
that from the Alexander Orr, Jr. plant, plus fluoridation
and the addition of air stripping in order to remove vola-
tile organic compounds.
Because source water supplied to the John E. Pres-
ton plant has a higher level of naturally occurring organ-
ic materials than the water at the other plants, it goes
through a slightly different process called enhanced soft-
ening. It is disinfected, fluoridated and filtered, then it
goes through air stripping towers that remove volatile
organic compounds. This process has the added benefit
of reducing the yellow tint once present in water supplied
by the Preston plant.
The South Dade Water Supply System
The South Dade Water Supply System is comprised of
five smaller water treatment plants that serve residents
south of SW 264 Street in the unincorporated areas of
the county. These five plants pump treated water from
the Biscayne Aquifer into a common distribution sys-
tem, which is separate from the main system men-
tioned above. Water from these plants is disinfected
and stabilized for corrosion control.
Highly trained microbiologists, chemists, and water treatment specialists
conduct or supervise more than 100,000 analyses of water samples each
year. Water quality samples are collected throughout the county and tested
regularly. Samples include untreated and treated water taken at our facilities,
sample sites throughout the service areas and at customers' homes. These

Todo
Sobre Nuestra
Agua Potable - De
Donde Proviene y
Como Se Procesa
La unica fuente de agua potable para Miami-Dade sigue
siendo los pozos subterraneos del manto freatico. Es-
tos pozos derivan su fuente exclusivamente del Manto
Freatico Biscayne para la mayor parte del sistema del
Departamento. Para los clientes que reciben su agua de
la Planta de Procesamiento Alexander Orr, Jr., los pozos
que suministran agua a esta planta derivan su fuente
mayormente del Manto Freatico Biscayne, y en nienor
cuantia, del Manto Freatico Floridan.
En el 2008 el Departamento de Proteccion Ambiental
efectuo una evaluacion de nuestro sistema. La evalua-
cion fue realizada para proporcionar informacion sobre
la probabilidad de existir alguna fuente de contamina-
cion en la vecindad de nuestros pozos. Se identiflcaron
92 fuentes de contaminacion potenciales en este siste-
ma con niveles entre bajos y moderados de susceptibi-
lidad. Los resultados de la evaluacion estan disponibles
en el sitio web del Departamento de Proteccion Ambien-
tal de la Florida: www.dep.state.fl.us/swapp.
A Cuales Tratamientos Se
Somete Nuestra Agua Potable
La Planta de Procesamiento
Alexander Orr, Jr.
El agua de la planta Alexander Orr, Jr. recibe tratamien-
to de oxido de calcio para reducir su dureza y luego es
desinfectada y flltrada. Esta planta suministra may-
ormente agua del Manto Freatico Biscayne, la cual se
mezcla con menos cantidad de agua del Manto Freatico
Floridan. La planta Alexander Orr, Jr. presta servicios a
los residentes al sur de la calle 8 del Southwest hasta la
calle 264 del Southwest.
Las Plantas Hialeah y John E. Preston
El agua de las otras dos plantas regionales de procesa-
miento - Hialeah y John E. Preston - precede exclusiva-
mente del Manto Freatico Biscayne. Ellas, junto con la
Planta Alexander Orr, Jr., suministran agua procesada a
un sistema de distribucion comun el cual corre a lo largo
y ancho de la mayor parte del Condado Miami-Dade.
En general, las plantas Hialeah y John E. Preston pro-
cesan el agua que se suministra a los residentes que
viven al norte de la calle 8 del Southwest hasta la linea
divisoria entre los condados Miami-Dade y Broward.
El agua de la planta Hialeah recibe el mismo trata-
miento y se le anade fluoruro; ademas se limpia con aire
para remover compuestos organicos volatiles.
Debido a que la fuente del agua suministrada a la
planta Preston tiene un nivel mas alto de materiales
organicos que ocurren naturalmente si se le compa-
ra con el agua de las otras plantas, se le hace un
proceso ligeramente diferente conocido como
"suavizante realzado". Luego se desinfecta,
fluoriza y flltra. Despues pasa a traves de
la limpieza con aire para removerle com-
puestos organicos volatiles. Este nuevo
proceso tiene el beneflcio adicional de
reducir el tinte amarillo antes presente
en el agua suministrada por la
planta Preston.
El Sistema de Suministro de
Agua del sur de Miami-Dade
El sistema de suministro de agua del
sur de Miami-Dade esta compuesto
por cinco pequenas plantas de
Procesamiento de agua que prestan
servicios a los residentes al sur
de la Calle 264 del suroeste en el
area no incorporada del condado.
Estas cinco plantas bombean el
agua procesada a un sistema comun
de distribucion, separado del sistema
principal. El agua de esas plantas es
desinfectada y flltrada para controlar
la corrosion.

In the tables to the left, you may find unfamiliar terms and
abbreviations. To help you better understand these terms
we've provided the following definitions. En las tablas a mano
izquieida puede encontrar terminos y abreviaturas descono-
cidos. Para ayudarle a comprender me/or estos terminos le
presentamos las siguientes deSniciones.
Maximum Contaminant Level or MCL: The highest level of a
contaminant that is allowed in drinking water. MCLs are set
as close to the MCLGs as feasible using the best available
treatment technology. Maximo nivel de contamination: (MCL,
sus siglas en ingles) - El nivel maximo de un contaminante
que es permitido en el agua potable. Los MCL se Sjan lo mas
oeroa posible de los MCLG, utilizando la mejor teonologia de
tratamiento disponible.
Maximum Contaminant Level Goal or MCLG: The level of
a contaminant in drinking water below which there is no
known or expected risk to health. MCLGs allow for a mar-
gin of safety. Objetivo del nivel maximo de un contaminante
(MCLG, sus siglas en ingles) - El nivel de concentration de
un contaminante en el agua potable por debajo del cual no
se conoce o anticipa que produzca un riesgo a la salud. Los
MCLGs tienen en cuenta un margen de seguridad.
Action Level (AL): The concentration of a contaminant
which, if exceeded, triggers treatment or other requirements
that a water system must follow. Nivel de action (AL, sus
siglas en ingles) -La concentration de un contaminante que,
de ser excedido, provoca elprocesamiento u otro requisite a
seguir por un sistema de agua.
Maximum residual disinfectant level or MRDL: The high-
est level of a disinfectant allowed in drinking water. There is
convincing evidence that addition of a disinfectant is neces-
sary for control of microbial contaminants. Nivel maximo de un
desinfectante secundario (MRDL, sus siglas en ingles) - El nivel
maximo de un desinfectante permitido en el agua potable. Ex-
ists evidencia convincente de que la adicion de un desinfectante
es necesario para el control de contaminantes microbianos.
Maximum residual disinfectant level goal or MRDLG: The
level of a drinking water disinfectant below which there is
no known or expected risk to health. MRDLGs do not reflect
the benefits of the use of disinfectants to control microbial
contaminants. Objetivo del nivel maximo de un desinfectante
residual (MRDLG, sus siglas en ingles) - El nivel de un desin-
fectante de agua potable por debajo del cual no se conoce o
espera riesgo a la salud. Los MRDLGs no lefiejan los benefi-
cios del uso de los desinfectantes para controlar contami-
nantes microbianos.
"ND" means not detected and indicates that the substance
was not found by laboratory analysis. ND - No detectado;
indica que la sustancia no fue hallada por un analisis

5% of monthly samples. A minimum of 390 samples for total
coliform bacteria testing are collected each month from the
Main distribution system (55 samples from the South Dade
Water Supply distribution system) in order to demonstrate
compliance with regulations. El nivel maximo de la bacteria
coliforme indica que el agua potable no puede mostrar la
presencia de dicha bacteria en > 5% de las muestras men-
suales. De acuerdo con las regulaciones establecidas, un
minimo de 390 muestras para un total de la bacteria coliforme
son recogidas mensualmente del sistema principal de distri-
bution (55 muestras del sistema de suministro de agua del
sur de Miami-Dade).
(d) A total of 48 samples for Total Trihalomethane and
Haloacetic Acid testing are collected per year from the Main
distribution system (20 samples from the South Dade Water
Supply distribution system, and 8 from the Aventura dis-
tribution system) in order to demonstrate compliance with
State regulations. Compliance is based on a running annual
average. This is the value which precedes the parentheses.
De acuerdo con las regulaciones establecidas, un total de 48
muestras por sistema principal de distribution (20 muestras
del sistema de distribution del sur del condado Miami-Dade,
y 8 del sistema de distribution de Aventura) son revisadas
anualmente para medir el total de Trialometano y Acido
Haloacetico. Las exigencias para estar de acuerdo con las re-
gulaciones establecidas se basan en el promedio anual. Esto
se lefleja en las tifras colocadas antes del parentesis.
(e) Compliance is based on a running annual average,
computed quarterly from monthly samples collected during
total coliform bacteria testing. El cumplimiento se basa en
un promedio anual corriente, computado trimestralmente
de muestras recogidas mensualmente durante las pruebas
totales de bacteria coliforme.
(f) 90th percentile value reported. If the 90th percentile value
does not exceed the AL (i.e., less than 10% of the homes have
levels above the AL), the system is in compliance and is
utilizing the prescribed corrosion control measures. El 90 por
ciento del valor fue reportado. Si el 90por ciento no excede el
AL, {por consiguiente, menos del 10% de los hogares tienen
niveles por encima del AL}, el sistema esta de acuerdo con
las regulaciones y esta utilizando las medidas prescritas de
controlar la corrosion.
(g) The 08/06 data presented for the Main System, Aventura, and
South Dade System respectively is from the most recent testing
conducted in accordance with regulations. These systems are
under reduced monitoring which only requires testing every 3
years. Los datos delos anos 2008 y 2006 {08/06} presentados por
el sistema principal, el sistema de Aventura, y por el sistema de
distribution del sur de Miami-Dade respectivamente, son de los
examenes mas recientes llevados a cabo en acuerdo con las regu-
laciones. Estos sistemas requieren ser inspeccionados solamente
cada 3 anos.
(h) Fluoride testing to demonstrate compliance with State
regulations is required every 3 years in accordance with the
State's monitoring framework. However, fluoride levels are
monitored daily for the Main System treatment plants where
fluoride is added to promote strong teeth. Pruebas de fluoiuio
para demostrar concordantia con las regulaciones estata-
les son requeridas cada 3 anos. Sin embargo, en el sistema
principal, donde se anade fluoiuio para promover dentaduras
fuertes, los niveles de fluoiuio son examinados diariamente.

WATER QUALITY REPORT 2008 INFORME SOBRE LA CALIDAD DEL AGUA
Additional Information
About Your Water
The sources of drinking water (both tap water and
bottled water) include rivers, lakes, streams, ponds,
reservoirs, springs, and wells. As water travels over the
surface of the land or through the ground, it dissolves
naturally occurring minerals and, in some cases, radio-
active material, and can pick up substances resulting
from the presence of animals or from human activity.
Contaminants that may be present in source
water include:
Microbial contaminants, such as viruses and bacte-
ria, which may come from sewage treatment plants,
septic systems, agricultural livestock operations,
and wildlife.
Inorganic contaminants, such as salts and metals,
which can be naturally-occurring or result from urban
stormwater runoff, industrial or domestic wastewater
discharges, oil and gas production, mining, or farming.
Pesticides and herbicides, which may come from a
variety of sources such as agriculture, urban storm-
water runoff, and residential uses.
Organic chemical contaminants, including synthetic
and volatile organic chemicals, which are by-prod-
ucts of industrial processes and petroleum produc-
tion, and can also come from gas stations, urban
stormwater runoff, and septic systems.
Radioactive contaminants, which can be naturally
occurring or be the result of oil and gas production
and mining activities.
In order to ensure that tap water is
safe to drink, the EPA prescribes
regulations, which limit the amount
of certain contaminants in water
provided by public water systems.
The Food and Drug Administration
(FDA) regulations establish limits
for contaminants in bottled water,
which must provide the same pro-
tection for public health.
Drinking water, including bottled
water, may reasonably be expected
to contain at least small amounts of
some contaminants. The presence
of contaminants does not necessar-
ily indicate that the water poses a
health risk. More information about
contaminants and potential health
effects can be obtained by calling
the Environmental Protection Agen-
cy's Safe Drinking Water Hotline at
1-800-426-4791.
Mas Informacion
Sobre Su Agua
Las fuentes de agua potable (tanto agua corriente como
embotellada) incluyen rios, lagos, riachuelos, lagunas,
represas, manantiales y pozos. A medida que el agua
se desplaza sobre la superflcie de la tierra o a traves de
los terrenes, disuelve minerales naturales y en algunos
cases materiales radiactivos y puede recoger sustancias
que resultan de la presencia humana y de animates.
Los contaminantes que pudieran encontrarse en las
fuentes de agua incluyen:
Contaminantes microbianos, tales como virus y bacte-
rias que pueden provenir de plantas de tratamiento de
aguas negras, sistemas septicos, empresas agricolas y
de ganado, y tambien de la fauna.
Contaminantes inorganicos, tales como sales y met-
ales, que pueden ocurrir naturalmente o como resul-
tado de aguas pluviales en zonas urbanas, de descar-
gas industrials o domesticas de aguas albanales,
de la produccion de petroleo o gas, de la mineria y de
la agricultura.
Pesticidas y herbicidas, que pueden venir de una varie-
dad de fuentes como, la agricultura, las aguas pluviales
en zonas urbanas y usos residenciales.
Contaminantes quimicos organicos, incluyendo pro-
ductos quimicos organicos sinteticos y volatiles que
tambien pueden venir de estaciones de gasolina,
escurrimiento de aguas pluviales de zonas urbanas y
sistemas septicos.
Contaminantes radiactivos, los cuales pueden ocurrir
naturalmente o ser el resultado de la produccion de gas o
petroleo o de actividades mineras.
Para poder cerciorarse de que el agua de la Have se
pueda beber, la EPA hace recomendacio-
nes que limitan la cantidad de ciertos
contaminantes que puede hallarse en
el agua suministrada por los sistemas
publicos de agua. Las normas de la Ad-
ministracion de Alimentos y Farmacos
o FDA (sus siglas en ingles) establecen
limites maximos de la cantidad de con-
taminantes que pueden hallarse en

For Customers with Special Health Concerns
Some people may be more vulnerable to contaminants in drinking water than the general population. Immu-
no-compromised persons such as persons with cancer undergoing chemotherapy, persons who have under-
gone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants
can be particularly at risk from infections. These people should seek advice about drinking water from their
health care providers. EPA/CDC guidelines on appropriate means to lessen the risk of infection by Crypto-
sporidium and other microbiological contaminants are available from the Safe Drinking Water Hotline at
1-800-426-4791.

What Should You
Know About Certain
Contaminants?
Radon
Radon 222, or radon for short, is a colorless, odorless gas that occurs naturally in soil,
air and water. Radon is formed from the radioactive decay products of natural uranium
that is found in many soils. Most radon in indoor air comes from the soils below the
foundation of the home, and in some locations can accumulate to dangerous levels in
the absence of proper ventilation. In most homes, the health risk from radon in drink-
ing water is very small compared to the health risk from radon in indoor air. For more
information, call the EPA's Radon Hotline at 1-800-SOS-RADON.
We have detected radon in the finished water supply, as noted in the Radon
Data Summary table on page 3. There is currently no federal regulation for radon
levels in drinking water. Exposure to air-transmitted radon over a long period of
time may cause adverse health effects.
Cryptosporidium
WASD first tested for Cryptosporidium in 1993 and has continued testing
monthly since 1994. To date, neither Cryptosporidium nor Giardia - another pro-
tozoan - have been found in the source water supplying WASD's water treat-
ment plants.
Nitrate
Although the level of nitrate (refer to the table on water quality data, p. 3) is consis-
tently below the health effect level, the EPA requires the following information be
included in this report: "Nitrate in drinking water at levels above 10 ppm is a health
risk for infants of less than six months of age. High nitrate levels in drinking water
can cause blue-baby syndrome. Nitrate levels may rise quickly for short periods of
time because of rainfall or agricultural activity. If you are caring for an infant, you
should ask advice from your health care provider."
Lead
If present, elevated levels of lead can cause serious health problems, especially
for pregnant women and young children. Lead in drinking water is primarily
from materials and components associated with service lines and home plumb-
ing. WASD is responsible for providing high quality drinking water, but cannot
control the variety of materials used in plumbing compo-
nents. When your water has been sitting for sev-
eral hours, you can minimize the potential
for lead exposure by flushing your tap for
30 seconds to 2 minutes before using
water for drinking or cooking. If you
are concerned about lead in your
water, you may wish to have
your water tested. Information
on lead in drinking water,
testing methods, and steps
you can take to minimize
exposure is available from
the Safe Drinking Water
Hotline at 1-800-426-4791
or at http://www.epa.gov/
safewater/lead.
iQue deberia saber
sobre ciertos
contaminantes?
Radon
Radon 222, mejor conocido simplemente como Radon, es un gas inodoro e incoloro
que ocurre naturalmente en la tierra, el aire y el agua. El radon proviene del des-
perdicio radiactivo de productos de uranio natural que se encuentran en muchas
tierras. La mayoria del radon en el aire interior viene de las tierras debajo de los
cimientos del hogar y, en algunas zonas puede llegar a acumularse en niveles pe-
ligrosos si no hay ventilacion apropiada. En la mayoria de los hogares, el riesgo a
la salud presentado por el radon en el agua potable es muy pequeno, comparable
al riesgo para la salud presentado por el Radon del aire interior. Para obtener mas
informacion, llame a la linea sobre el radon de la EPA por el 1-800-SOS-RADON.
Como aparece en la tabla de informacion acerca del Radon en la pagina 3, esta
sustancia ha sido hallada en el punto final del suministro de agua. En la actualidad,
las reglas federates no han dictado un nivel del radon en el agua potable. Estar ex-
puesto durante un largo periodo de tiempo a gases de radon emitidos a traves del
aire puede causar efectos adversos de salud..
Crip toesp oridio
En 1993 el Departamento comenzo a hacer pruebas para detectar criptoesporidio. A
partir del ano 1994, estos examenes se llevan a cabo mensualmente. Hasta la fecha,
no se ha encontrado ni criptoesporidio ni giardia, otro protozoo, en la fuente de agua
que suministra a las plantas de tratamiento del Departamento.
Nitrato
Aunque el nivel de nitrato, (por favor, refierase a la tabla sobre la calidad del agua
en la pagina 3), esta reiteradamente por debajo de la concentracion en que puede
tener algun efecto danino para la salud, la EPA requiere que proveamos la siguiente
informacion: "El nitrato, en concentraciones de 10 ppm o mas, en el agua potable,
constituye un riesgo a la salud de bebes de menos de seis meses de edad. Altos
niveles de Nitrato puedan causar el sindrome de "Bebe Azul" o "Blue Baby". Los
niveles de Nitrato pueden subir rapidamente por cortos periodos de tiempo de-
bido a un aumento de lluvia o de actividad agricola. Si usted cuida de un bebe,
le recomendamos que consulte con su medico".
Plomo
De estar presente, niveles elevados de plomo pueden causar problemas graves
de salud, especialmente para mujeres embarazadas y ninos pequenos. El
plomo en el agua potable deriva principalmente de materias y com-
ponentes asociados con lineas de servicio y tuberias en el hogar.
WASD es responsable de proporcionar agua potable de alta cali-
dad pero no puede controlar la variedad de materiales utiliza-
dos en los componentes de cada sistema de plomeria. Si sus
Haves han estado cerradas por varias horas, usted puede
disminuir el potencial de haber estado expuesta al plomo
dejando correr la Have entre 30 segundos a 2 minutos an-
tes de utilizar el agua para beber o cocinar. Si tiene algu-
na preocupacion acerca del posible contenido de plomo
en su agua potable puede examinarla. Informacion sobre
la existencia de plomo en el agua potable, metodos para
examinarla y pasos que puede tomar para reducir las
probabilidades que esto ocurra estan disponible a traves
de la Linea Directa del Agua al 1-800-426-4791 o en el si-
tio: http://www.epa.gov/safewater/lead.

2009 Consumer Confidence
Water Quality Report
The City of Helena Public Water System
Identification, (PWSID) Number MT0000241
currently serves 8100 residential and 2152
commercial water accounts with a yearly
average of 5.2 million gallons of water each
day. Water is supplied to fire hydrants to
ensure the safety of homes and businesses.
Last year, the Water Treatment Division
produced a total of 1.9 billion gallons of
water with a maximum production of 12.7
million gallons on a single day. The City of
Helena's Source Water Protection Plan for
Public Water System can be viewed on the
DEQ Web Site
http://nris.state.mt.us/wis/swap/SwapQuery.a
sp_
This year the City will complete the 1.5
million gallon clear well for disinfection and
a new energy efficient High Zone Pumping
Station at MRTP to improve reliability,
maintain regulatory compliance, and meet
future growth needs. The City's Utility
Maintenance Division will replace sections of
deteriorated water mains to improve system
dependability, and reduce water loss due to
leakage.
Water System To meet Helena's water
needs, the City's Water Treatment Division
operates two surface water treatment plants;
the Missouri River Treatment Plant (MRTP)
east of Helena and the Tenmile Water
Treatment Facility west of Helena.
Additional water is produced from the Eureka
Well located at Cruise and Park Avenues.
This pure groundwater source does not
require further treatment.
Water Treatment - This process consists of
a series of steps to refine the quality of the
source or raw water. Chemicals are added to
the raw water causing small particles to
adhere to each other making them heavy
enough to settle into a basin or collect on
special media. The particles are then flushed
to waste lagoons. Next the water is filtered
through layers of fine anthracite coal filters
and silicate sand removing suspended
particles. During filtration, turbidity is
removed and clear water emerges. Prior to the
water being sent to the distribution system, a
small amount of chlorine is added to ensure
the water remains free of any virus or
bacteria. These treatment processes are
manned and operated by a team of highly
trained, state certified water treatment
professionals, and assisted by computerized
supervisor control and data acquisition
systems. (SCADA)
Sampling - Regular sampling and testing is
an important assurance of the quality of water
and includes the following:
Daily: Chlorine Residuals, Turbidity, pH,
Temperature and Color (NTU)
Weekly: Bacteria (total coliform)
Quarterly: Trihalomethanes, Haloaecetic
Acids
Yearly: Inorganics, Volatile Organic
Contaminants, Nitrates
3 years Lead & Copper
4 years Radioactivity
If present, elevated levels of lead can cause
serious health problems especially for
pregnant women and young children. Lead
in drinking water is primarily from materials
and components associated with service lines
and home plumbing. The City of Helena is
responsible for providing high quality
drinking water, but can not control the variety
of materials used in plumbing components.
When your water has been sitting for several
hours, you can minimize the potential for
lead exposure by flushing your tap for 30
seconds to 2 minutes before using water for
drinking or cooking. If you are concerned
about lead in your water, you may wish to
have your water tested. Information on lead
in drinking water, testing methods, and steps
you can take to minimize exposure is
available from the Safe Drinking Water
Hotline 1-800-426-4791 or
http://www.epa.gov/safewater/lead
Radon is a naturally occurring radioactive gas
in the earth's crust. It is soluble in water and
is tasteless, colorless and odorless. Helena's
surface and ground water sources detection
ranged from 220 pCi\ 1 to 1770 pCi/L . The
U.S. EPA is proposing a MCL of 300 pCi\L
in drinking water with an alternative MCL of
4000 pCiYL for systems that implement a
Multi-Media Mitigation Program. There is
no federal regulation for radon levels in
drinking water as of this printing. Exposure
to air transmitted radon over a long period of
time may cause adverse health effects. For
additional information call the state radon
program at 444-5318 or EPA's Radon
Hotline (1-800-SOS-RADON).
Monitoring - Both, Energy Laboratories,
Inc. & Alpine Analytical Inc. in Helena are at
the heart of our quality assurance program.
Their independent testing by certified
chemists and technicians follows precise
procedures established by the U.S.
Environmental Protection Agency (EPA).
Turbidity is a measure of the clarity of
water. We monitor this as an indicator of the
effectiveness of our filtration system.
pH is an expression of the basic or acidic
condition of a liquid. The pH scale ranges
from 0 to 14. Neutral being 7, the most
acidic is 0 the most caustic is 14. Natural
waters typically have a pH between 6.8 and
8.5. The pH in our system has a pH of 7.2 to
8.5
Hardness is a natural characteristic of water
caused by dissolved calcium and magnesium.
The Maximum Contaminant Level (MCL) is
300 mg/L.
Tenmile 24.67 mg/L 1.7 grains/gal
MRTP 135.71 mg/L 9.5 grains/gal
Eureka 232.00 mg/L 16.8 grains/gal
Listed below are the substances that were
detected and analyzed by Energy Lab Inc.
for the Helena Water Treatment Division.
The maximum contaminated levels (MCL)
apply to the water within our distribution
system, after treatment, including
groundwater sources. The U.S. EPA and the
State of Montana have established MCL's at
levels that assure public health and safety
with a very low risk of health impacts.

All sources of drinking water are
subject to potential contamination
by constituents that are naturally
occurring or man made. Those
constituents can be microbes,
organic or inorganic chemicals, or
radioactive materials. All drinking
water, including bottled water, may
reasonably be expected to contain at
least small amounts of some
contaminants. The presence of
contaminants does not necessarily
indicate that the water poses a
health risk. More information about
contaminants and potential health
effects can be obtained by calling
the U.S. EPA's Safe Drinking
Water Hotline.
Some people may be more
vulnerable to contaminants in
drinking water than others.
Immuno-compromised persons such
as persons undergoing
chemotherapy, persons who have
undergone organ transplants, people
with HIV/AIDS or other immune
system disorders, the elderly, and
infants can be particularly at risk
from infections. These people
should seek advice about drinking
water from their health care
providers. The EPA and Centers
for Disease Control guidelines on
appropriate means to lessen the risk
of infection by Cryptosporidium
and other microbiological
contaminants are available from the
Safe Drinking Water Hotline
In September 2008, The Department
of Environmental Quality issued a
noncompliance for monitoring due
to a sampling procedural error. On
September 3rd, 2008 The City of
Helena pulled a bacteriological
sample and received a false
positive. On average, the City
collects 33 samples a month. In
September we had over 50 samples
analyzed by 2 independent labs to
verify that the City's water was
indeed safe and not contaminated
with bacteria. A Public notice was
advertised as required by the
regulatory agency.
