Regular Meeting Authorization
REQUEST: Utility Department Providing the City Commission with a copy of the
Consumer Confidence Report that will be sent to all residents.
SYNOPSIS: The purpose of this Board item is to inform the City Commission that a Consumer
Confidence Report will again be sent to all Residents which is an Annual Report on
the Quality of their Drinking Water
CONSIDERATIONS:
The 1996 Safe Drinking Water Act Amendments require that, beginning in October
1999, all community water systems provide customers with an annual report on the quality of
their drinking water. It is called the Consumer Confidence Report or CCR. The report format
and content are mandated by the local DEP office.
This year, same as last year, we are not required to include the separate notice of the
groundwater contamination investigation by FDEP that has been ongoing since first reported in
2001. The two primary sources of contamination are the Dearborn electronics site on 17 -92
and multiple areas on Seminola Boulevard in Casselberry west of Murphy Road. We continue
to sample quarterly times per year at each well at WTP #2 (Sheoah Boulevard) and WTP #3
(Bahama Road) and the levels have shown little variation.
This is the tenth year that the report will be provided to utility customers. A copy of the
CCR is attached. The report will be mailed in June.
FISCAL IMPACT:
The postage and printing cost for the CCR is $4,000 from the Utility Fund.

2009 Annual Drinking Water Quality Report for the
City of Winter Springs
We're very pleased to provide you with this year's Annual Water Quality Report. We
want to keep you informed about the excellent 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. Our water source is ground water from wells. The
wells draw from the Floridan Aquifer.
Our Water is obtained from ground water sources and is chlorinated for disinfection and health
purposes. 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 the water
treatment facility at 407 - 327 -8992 from 8:00 am till 5:00 pm
In 2009 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 were (2) potential source of contamination identified
for this system with a moderate susceptibility level. The assessment results are available on the FDEP
Source Water Assessment and Protection Program website at www.dep.statefl.us /swapp
City of Winter Springs routinely monitors for contaminants in your drinking water according to
Federal and State laws, rules, and regulations. Except where indicated otherwise, this report is based
on the results of our monitoring for the period of January 1 to December 31, 2009. Data obtained
before January 1, 2009, and presented in this report are from the most recent testing done in
accordance with the laws, rules, and regulations.
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 microbiological
contaminants are available from the Safe Drinking Water Hotline (800- 426- 4791).
In the table below, you may find unfamiliar terms and abbreviations. To help you better understand
these terms we've provided the following definitions:
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.
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 margin of safety.
Action Level (AL): The concentration of a contaminant which, if exceeded, triggers treatment or other requirements that a
water system must follow.
Initial Distribution System Evaluation (IDSE): An important part of the Stage 2 Disinfection Byproducts Rule (DBPR).
The IDSE is a one -time study conducted by water systems to identdy distribution system locations with high concentrations
of trihalomethanes (THMs) and haloacetic acids (HAAs). Water systems will use results from the IDSE, in conjunction with
their Stage 1 DBPR compliance monitoring data, to select compliance monitoring locations for the Stage 2 DBPR.
Maximum residual disinfectant level or 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 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.
Nephelometric Turbidity Unit (NTU) - measure of the clarity of water. Turbidity in excess of 5 NTU is just noticeable to
the average person.
"ND" means not detected and indicates that the substance was not found by laboratory analysis.
Parts per billion (ppb) or Micrograms per liter (µg/1) — one part by weight of analyte to 1 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 1 million parts by weight of the
water sample.
Picocurie per liter (pCi/L) - measure of the radioactivity in water.
Treatment Technique (TT): A required process intended to reduce the level of a contaminant in drinking water.
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 Winter Springs 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 http: / /www.epa.gov /safewater /lead.
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, septic
systems, agricultural livestock operations, and wildlife.
(B) Inorganic contaminants, such as salts and metals, which can be naturally- occurring or result from urban
storm water runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming.
(C) Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban storm water
runoff, and residential uses.
(D) 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 storm water
runoff, and septic systems.
(E) 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 protection 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 necessarily indicate that the water poses
a health risk More information about contaminants and potential health effects can be obtained by
calling the Environmental Protection Agency's Safe Drinking Water Hotline at 1- 800 - 426 -479
