AGENDA ITEM: Annual Water Quality Report
SUBMITTED BY: Donna Kaluzniak, Utility Director
DATE: April 16, 2007
BACKGROUND: A copy of the 2007 Water Quality Report for the City of Atlantic Beach is
provided for the City Commission's review. The Florida Department of Environmental
Protection requires annual water quality reports be mailed to all customers by the first of July
every year.
The City is required to test for over 80 drinking water contaminants, but only those detected
during analysis are included in the report. As shown, detected values were within the levels
allowed and we had no violations of water quality limits.
BUDGET: A total of $5,000 is budgeted in the Water Fund for printing and mailing the reports,
under account numbers 400 - 5502 -533 -4200 and 400 - 5502 -533 -4700.
RECOMMENDATION: No action necessary. The report is provided for information only.

2007 Water Quality Report
CITY OF ATLANTIC BEACH, FLORIDA
In the table you will find many terms and abbreviations you might not be familiar with. To help you better
understand these terms, we have provided the following definitions:
Action Level (AL) —The concentration of a contaminant which, if exceeded, triggers treatment or other
requirements which a water system must follow.
Maximum Contaminant Level (MCL) — The "Maximum Allowed" (MCL) is 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 "Goal" (MCLG) is 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 Residual Disinfectant Level (MRDL) – The highest level of a disinfectant allowed in drinking water.
There is a 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 contaminants.
Non - Detects (ND) — Means not detected and indicates that the substance was not found by laboratory analysis.
Not Applicable (N /A) – The information does not apply in this category or for this contaminant.
Parts per billion (ppb) or Micrograms per liter (ug/L) – One part by weight of analyte to one billion parts by
weight of the water sample.
Parts per million (ppm) or Milligrams per liter (mg/L) – One part by weight of analyte to one million parts by
weight of the water sample.
Picocuries per liter (pCi/1) – Measure of the radioactivity in 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, 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:
(A) Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants or
septic systems. While the City's wastewater treatment plant meets strict effluent limitations and does not
discharge to the groundwater, private septic systems are not monitored, and may discharge to the groundwater.
(B) Inorganic contaminants, such as salts and metals, which can be naturally occurring from erosion of deposits
within the aquifer.
(C) Pesticides and herbicides, which may come from a variety of sources such as residential uses, and can be
minimized or eliminated by cross - connection control.
(D) Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by- products
of industrial processes, and can also come from leaking underground fuel tanks at gas stations, and septic
systems.
(E) Radioactive contaminants, which can be naturally present in the aquifer.
While your drinking water meets USEPA's standard for arsenic, it does contain low levels of arsenic. USEPA's
standard balances the current understanding of arsenic's possible health effects against the costs of removing
arsenic from drinking water. USEPA 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.

2007 Water Quality Report --
CITY OF ATLANTIC BEACH, FLORIDA
We are very pleased to provide you with this
year's Annual Water Quality Report. We
want to keep you informed about the excel-
lent water and services we have delivered to
you over the past year. Our goal is, and
always has been, to provide to you a safe
and dependable supply of drinking water.
This report shows our water quality results
and what they mean.
Our water source is the Floridan Aquifer,
which is similar to a large underground
river. Groundwater is pumped from eight
wells that are approximately 700 to 1000
feet deep. This water is aerated to remove
sulfides and chlorinated for disinfection at
the four separate Water Treatment Plants.
Trained, state certified plant operators
ensure proper treatment of the average 3.5
million gallons per day of water provided to
our customers. We are pleased to report
that our drinking water meets all Federal
and State requirements.
If you have any questions about this report
or concerning your water utility, please
contact Mr. Harry McNally, Plants Division
Director at 904 - 247 -5838. We want our
valued customers to be informed about their
water utility.
The City of Atlantic Beach's legislative
body is the Atlantic Beach City Commis-
sion, which holds hearings on budget,
approves contracts, and considers ordin-
ances which create or amend local laws.
Some of these matters affect the operation of
the Water Utility. If you want to become
informed about upcoming water - related
projects or programs, please attend any of
our City Commission meetings which are
scheduled on the 2 nd and 4 Monday of
every month at 6:00 p.m. at City Hall, 800
Seminole Road, Atlantic Beach, Florida
32233, or call or e -mail our Public Utilities
Director, Ms. Donna Kaluzniak, at 904 -270-
2535, dkaluzniak @coab.us.
The City of Atlantic Beach routinely moni-
tors for contaminants in your drinking water
according to Federal and State laws. Except
where indicated otherwise, the table in this
report shows the results of our monitoring
for the period of January 1st to December
31 st, 2007.
As authorized and approved by the EPA
(Environmental Protection Agency), the
State has reduced monitoring requirements
for certain contaminants to less often than
once per year because the concentrations of
these contaminants are not expected to vary
significantly from year to year. Some of our
data, though representative, is more than one
year old.
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 protection for public health.
AGENDA ITEM # 4C
APRIL 28, 2008
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 conta-
minants and potential health effects can be
obtained by calling the EPA's Safe Drinking
Water Hotline at 1- 800 -426 -4791.
The EPA requires monitoring of over 80
drinking water contaminants. Those conta-
minants listed in the table are the only ones
detected in your drinking water.
MCLs are set at very stringent levels. To
understand the possible health effects
described for many regulated contaminants,
a person would have to drink 2 liters of
water every day at the MCL level for a
lifetime to have a one -in -a- million chance of
having the described health effect.
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 micro- biological contaminants
are available from EPA's Safe Drinking
Water Hotline at 800 - 426 -4791.
In 2006 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 twelve
potential sources of contamination identified
for our system with low to medium suscep-
tibility levels, mostly due to petroleum
storage tanks. To protect our source waters,
the City recently enacted a Wellhead Protec-
tion Ordinance. Also, DEP has a very active
petroleum contamination prevention pro-
gram and some of the most stringent rules in
the country. The assessment results are
available on the FDEP Source Water As-
sessment and Protection Program website at
www. dem state. fl.us /swapp
Thank you for allowing us to continue
providing your family with clean, quality
water this year. In order to maintain a safe
and dependable water supply we sometimes
need to make improvements that will benefit
all our customers. For instance, in the last
several years, we completed the construction
of a 300,000 gallon elevated water storage
tank, and replaced aging water mains. We
will continue to provide the highest quality
water supply possible.
We at the City of Atlantic Beach work
around the clock to provide top quality
water to every tap. We ask that all our
customers help us protect our water sources.
