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 hy the local DEP office. There were coliform violations this past year included in this report which were previously noticed in the paper and also on the web page for 45 days. The additional explanation requested by the Commission in the notice has been incorporated into this report. Although not included in the report, the solvent contaminant being monitored on the west side decreased to non-detectable levels in the January sample but we will still continue to sample the west side wells twice per year to monitor any changes. DEP is to provide us a report by July and we will forward that information when available. This is the sixth year that the report will be provided to utility customers. A copy of the CCR is attached. The report will be sent out in June/July. ATTACHMENTS: 1. Consumer Confidence Report COMMISSION ACTION: None required. Annual Drinking Water Report The City of Winter Springs East System J.D. 3591394 - 851 Northern Way WTP #1 West System J.D. 3590879 - 700 Sheoah Blvd. WTP- #2 & 110 W. Bahama Rd. WTP- #3 We're very pleased to provide you with this year's Annual Water Quality Report. We want to keep you informed about tbe water quality and services we have delivered to you over the past year. Our goal has always been, to provide to you a safe and dependable supply of drinking water. The Tuscawilla and Oak Forest areas are generally served by the East system with the remainder of the City served by the W cst system although the systems are interconnected. Our East facility delivers over 1 billion gallons of treated water annually. A total of three (3) production wells at this facility pump au average of 2.740 million gallons daily to meet the residential, commen::ial and irrigation needs. The fourth production well for this facility will be completed in 2005. Our West facilities deliver over 430 million gallons of treated water annually from both plants. A total of four (4) production wells pump an average of 1.177 million gallons daily to meet the residential, commercial and irrigation needs. These wells are located within close proximity to the plants and have an average depth of 350 feet, tapping into the Floridan Aquifer. At all of the Winter Springs treatment plants, cascading aeration trays are used to strip the water of Hydrogen Sulfide. The water is then disinfected by Chlorine gas or Sodium Hypochlorite before being pumped into the distribution system. If you have any questions about this report or concerning your water utility, please contact the water treatment facility at 327-8992 from 8:00 am to 4:30 P.M. Monday-Friday. We want our valued customers to be informed about their water utility. If you want to learn more, please attend any of our regularly scheduled commission meetings. They are held the second and fourth Monday of every month at 6:30 P.M. at City Hall. The City of Winter Springs routinely monitors for contaminants in your drinking water according to Federal and State laws. This table shows the results of our most recent monitoring period from January 1st to December 31st 2004. The state allows us to monitor for some contaminants less than once a year because the concentration of these contaminants does not change frequently. Some of our data, though representative, are more than one year old. All water analyses are the most recent sampling in accordance with the Safe Drinking Water Act. 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 Environmental Protection Agency's Safe Drinking Water Hotline at 1-800-426-4791, In this table you will find many terms and abbreviations you might not be familiar with. To help you better understand these terms we've provided the following definitions: Not Applicahle (N/A) - does not apply Non-Detects (ND) -laboratory analysis indicates that the constituent is not present. Parts per million wpm) or MiUiwams per liter (mgll) - one part Ilel" million corresponds to one minute in two years 01" a single penny in $10,000. Parts per billion (Ppb) or Micrograms per liter (ug/l) - one part per billion l~orresllOnds to one minute in 2,000 yean!, or It single peony in $10,000,000. Action Level (AL) _ the concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow. Picocuries per liter (pCiIl.) - Ilicocuries per liter is a mell1lurc of tbe radioactivity in water. Maximum Contaminant Level (MCL) - The "Maximum Allowed" is tbe higbest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using tbe best available treatment technology. Maximum Contaminant Level Goal (MCLG) - The "Goal" is tbe level of a contaminant in drinking water below which there is no known or expn..1ed risk to bealth. MCLGs allow for a margin of safety. MCLs are set at very stringent levels. To understand the possible health effects described for many regulated constituents, 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 llIV/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 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. Please call our office if you have questiuns. We at the City of Winter Springs work around the clock to provide top quality water to every tap. We ask that all our customers help us protect our water sources, which are the heart of our community, our way oflife and our children's future. 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, agriculturallivcstock operations, and wildlife. (B) Inorganic contaminants, such as salts and metals, which can be naturally-occurring or result from urban stoml 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 storrnwater runoff, and septic systems. (E) Radioactive contaminants, which can be naturally occurring or be the result of oil and gas production and mining activities. Tn order to ensure that tap water is safe to drink, EP A prescribes regulations that limit the amount of certain contaminants in water provided by public water systems. FDA regulations establish limits for contaminants in bottled water that must provide the same protection for public health. /n September of 2004, we were scheduled to take lead and copper residential samples un the F~st side. Due to the hurricanes, we were interrupted which resulted in a violation. We have rescheduled sampling for 2005. All previous samples taken in the last 10 years have been below the h-"'PA 's MCr reporting levels In November oj 2004, we had two bacteriological samples on the f.-,'ast and West system come back with a positive coliform result. These samples are collected at the hose bibs of individual homes and were likely contaminated during sampling. However, the four positive coliform results were one sample above that which is allowed, resulting in afailure (5% of all samples). Subsequently, multiple samples were pulled to co'~finn this result and all came back negative (no bacteria present). Coliform bacteria are naturally present in the environment and are used as indicators of potentially harmful bacteria. In June of2004, the Consumer Cor~fident Reportsjor 2003 were mailed on schedule to the public and immediately delivered tu the District office. 1he reports were not recorded at the District office until October of 2004. 111is resulted in a reporting violation. 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. 3591394 Winter Springs East TEST RESULT TABLE ..

An average tub holds 50 gallons afwater. Conserve water by only partially filling the tub. 2. Install water saving showerheads. 3. Only run dishwashers and washing machines with full loads. 4. Regularly check pipes, hoses, valves, and faucets for leaks 5. Add food coloring to the water in the tank. If color appears in bowl without flushing, there is a leak. Fix or replace parts. 6. Longer grass means less evaporation. Let grass grow taller in hot, dry weather. 7. Set irrigation timer for early morning, around 2 A.M. or 3 A.M. to help prevent evaporation and help to increase your water pressure for household activities. 8. Install an irrigation rain gauge to prevent over watering. 9. Use a broom instead of a water hose to clear debris from patios, driveways, and sidewalks. 10. Do not allow garden hose's to run unattended. Watering Restriction Even residential and commercial addresses can water their lawns Thursday and Sundays Odd residential and commercial addresses can water their lawns Wednesday and Saturday This includes all water sources including potable water, reclaimed water, surface water and wells. For more information on rules under the water restriction you can contact the City of Winter Springs Water Treatment facility at 407-327~8992.
