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 Florida Department of Environmental Protection office. This year, same as the last 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 and multiple areas on Seminola Boulevard in Casselberry west of Murphy Road. We continue to sample quarterly at each well at WTP #2 (Sheoah Boulevard) and WTP#3 (Bahama Road) and the levels have shown little variation. This is the 12th year that the report will be provided to utility customers. A copy of the CCR is attached. The report will be included in the June utility bills. Informational 101 PAGE 1 OF 2 - May 14, 2012 FISCAL IMPACT: The printing cost for the CCR has been reduced from $4,000 to $1,500 by working with Utility Billing staff to print with the utility bill rather than a separate mailing. COMMUNICATION EFFORTS: This Agenda Item has been electronically forwarded to the Mayor and City Commission, City Manager, City Attorney/Staff, and is available on the City’s Website, LaserFiche, and the City’s Server. Additionally, portions of this Agenda Item are typed verbatim on the respective Meeting Agenda which has also been electronically forwarded to the individuals noted above, and which is also available on the City’s Website, LaserFiche, and the City’s Server; has been sent to applicable City Staff, Media/Press Representatives who have requested Agendas/Agenda Item information, Homeowner’s Associations/Representatives on file with the City, and all individuals who have requested such information.

We want to keep you informed about the water quality and excellent 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 to 5:00 pm In 2011 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.state.fl.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, 2011. Data obtained before January 1, 2011, and presented in this report are from the most recent testing done in accordance with the laws, rules, and regulations.

Ì®»¿¬³»²¬ Ì»½¸²·¯«» øÌÌ If present, elevated levels of lead can cause serious health problems, especially for pregnant women andyoung children. Lead in drinking water is primarily from materials and components associated withservice lines and home plumbing. The City of Winter Springs is responsible for providing high qualitydrinking water, but cannot control the variety of materials used in plumbing components. When yourwater has been sitting for several hours, you can minimize the potential for lead exposure by flushingyour 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 In our continuing efforts to maintain a safe and dependable water supply, it may be necessary to make improvements in your water system. The costs of these improvements may be reflected in the rate structure. Rate adjustments may be necessary in order to address these improvements. 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 of our customers. These improvements are sometimes reflected as rate structure adjustments. Thank you for understanding.

The program seeks to promote water conservation and reduce water consumption among City residents through education, incentive programs, free services such as irrigation audits, and more. Did you know that Florida withdraws more groundwater than any other state east of the Mississippi? Our groundwater is a clean, affordable source of drinking water, but it is not an inexhaustible resource. If we do not conserve our groundwater, we may have to resort to alternative sources of drinking water such as surface water treatment and/or desalination, both of which are much more costly than our current source of water, the Floridan aquifer. The economically and environmentally sensible solution is to conserve the groundwater resources we currently utilize. Irrigation can account for more than 50% of residential water use. You can conserve water by following the watering restrictions listed below. The City of Winter Springs encourages you to request a free irrigation audit to learn how you can maintain a healthy, green lawn while irrigating efficiently and reducing your monthly water bill. For more information on the water conservation program or to schedule an irrigation audit, please contact Water Conservation Coordinator, Stephanie Wolfe at 407-327-6584, swolfe@winterspringsfl.org. You can also visit our water conservation webpage on the City website at www.winterspringsfl.org.
