Item 4CAGENDA ITEM # 4C APRIL 28, 2008 CITY OF ATLANTIC BEACH CITY COMMISSION MEETING STAFF REPORT 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. ATTACHMENTS: 1. 2007 Atlantic Beach Water Quality Report REVIEWED BY CITY MANAGER: AGENDA ITEM # 4C APRIL 28, 2008 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.

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.
