REQUEST: Utility Department Providing the City Commission with a copy of the Consumer
Confidence Report that will be sent to all residents.
PURPOSE: 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, unlike the previous three years, 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 north of Shepard Road 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 levels have dropped slightly.
Results for Dichloromethane were below detection limits this year and not reportable.
Results for cis-1,2-Dichloroethylene were at 1.26 parts per billion (ppb) pb with an MCL of 5.0
parts per billion in the east system. Results for cis-1,2-Dichloroethane were at 0.86 ppb also
with an MCVL of 5.0 ppb. When contaminants are detected at the action level (half the MCL),
DEP requires a plan of action be submitted to address removal of the contaminants when the
MCL is reached. The most common method of removal is air stripping. The rate study currently
ongoing will ascertain the potable water rates necessary to support the construction of air
strippers should the Commission decide to proceed prior to the State action thresholds.

2008 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 S: 00
pm
In 2004 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 was (1)
potential source of contamination identified for this system with a moderate
susceptibility level. 7'he 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.7anuary
1 to December 31, 2008. Data obtained before January 1, 2008, 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 HIY/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 identify
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.
Million fibers per liter (MFL) -measure of the presence of asbestos fibers that are longer than 10
micrometers.
Millirem per year (mrem/yr) -measure of radiation absorbed by the body.
Nephelometric Turbidity Unit (NTU) -measure of the clarity of water. Turbidity in excess of S 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 (,ug/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 (7'T): 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.
City of Winter Springs May 2009
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 stormwater 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
stormwater 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 stormwater 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 waterprovided bypublic 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 1-800-426-4791.

Reclaimed �L"ater Information
What is Reclaimed Water?
Reclaimed Water is a.seri•ic•c s�upplic�cl hl� �h� C'in• uf �[i"ir��E�r Spr�irigs �'�ili�t� Depur��inent �o limitc�c! areas
within the service.
Reclaimed Water is the result of highly treated and disinfected sanitary wastewater w-hich is primaril�
used for irrigation. Irrigation of edible crops that will be peeled, skinned or thermally processed before
consumption is permitted, but all other edible crops must be irrigated indirectly. "Indirect application
irriQation " and "indirect contact irriQation " mean irrigation methods, such as ridge and furro►1�
irrigation drip irriQation, and subsurface distribution systems, which minimize direct contact of
reclaimed water ti1•ith the edible crop.
Is Reclaimed Water Safe? I �
• Reclaimed Water is safe and beneficial for irrigation purposes but should not to be used for '
drinking, bathing or filling swimming pools. The Waste Water Treatment Facilities operational
process has established safeguards and a strict Monitoring and Operating Protocol is always
followed The reclaimed water is essentially free of bacteria and viruses but the treatment
process does not remove the beneficial nitrogen.
• The treatment facilities have continuous 24 hour 7 days per week on-line monitoring with
automatic diversion and rejection of unacceptable quality reclaimed water.
Reclaimed water service areas are currently limited.
The City of Winter Spring has expanded the reclaimed water system to the point that the demand at
times exceeds the supply and restrictions have had to be placed on its use. Further expansion of the
reclaimed water system is in the planning stages until funding (i.e. rate increases) are approved. The
City is presently in the design phase to build a treatment facility to treat and use the water from Lake
Jesup to augment the reclaimed water supply. Upon completion of this facility, the City will begin
expanding the reclaimed distribution system. If you have questions as to when reclaimed water will be
a��ailable in vour neighborhood you can call Doug Ta��lor at 407-327-2669.
