2008 Consumer Confidence Report
Is my drinking water safe
YES, our water meets all of EPA’s Health Standards. In 2007, we conducted over 4500 tests for contaminants that may be found in drinking water. As you’ll see in the Water Quality Data chart on the back, we only detected 10 of these contaminants, and found all of those at safe levels. For Quality Control purposes the Water Treatment Plant is manned around the clock.What is the source of my drinking water?
Your water, which is surface water, comes from the Center Hill Lake (Mine Lick Creek). Our goal is to protect our water from contaminates and we are working with the State to determine the vulnerability of our water source to potential contamination. The Tennessee Department of Environment and Conservation (TDEC) has prepared a Source Water Assessment Program (SWAP) Report for the untreated water sources to potential contamination. To ensure safe drinking water, all public water systems treat and routinely test their water. Water sources have been rated as reasonably susceptible (high), moderately susceptible (moderate) or slightly susceptible (low) based on geologic factors and human activities in the vicinity of the water source. The Cookeville Water Department system sources rated as moderately susceptible to potential contamination.
Why are there contaminants in my drinking water?
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 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 (800-426-4791).
How can I get involved?
If you have any questions or concerns please call or come by our offices. The City Council meets on the first and third Thursday of each month. If you have any items that you wish to address, please call City Hall at 526-9591 to be placed on the agenda.
Is our water system meeting other rules that govern our operations?
The State and EPA require us to test and report our water on a regular basis to ensure its safety. We have always met all of these requirements. We want you to know that we pay special attention to all of the rules.
Taste and odor
For the most part taste and odor problems are the result of iron, algae and manganese. We use additives such as hydrogen peroxide and activated carbon in an effort to eliminate these problems.
Do I need to take special precautions?
Some people may be more vulnerable to contaminants 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 their personal sanitation, food preparation, handling infants and pets, and 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). We had 0 sites out of a total of 30 sites sampled to exceed the lead or copper action level. Infants and young children are typically more vulnerable to lead in drinking water than the general population. It is possible that lead levels at your home may be higher than at other homes in the community as a result of materials used in your home’s plumbing. If you are concerned about elevated lead levels in your home’s water, you may wish to have your water tested. To be safe, flush your tap for 30 seconds to 2 minutes before using tap water. Additional information is available from the Safe Drinking Water Hotline (800-426-4791).
For more information about your drinking water, please call Rodger Phillips at the Cookeville Water Treatment Plant at (931) 858-2646, or Barry Turner at the Dept of Water Quality Control Business Office at (931) 520-5258 or come by the offices between 8:00am and 4:30pm located at: 1860 S. Jefferson, Cookeville TN 38506.
Most of the Contaminants that we sample for were not detected (ND). The following chart shows only those contaminants that were detected. None of the contaminants detected were at high enough levels to be a violation of the Water Quality Standards. All monitoring results of regulated and unregulated contaminants, including VOC’s are available at the office of Cookeville Water Quality Control.
* Most of the data presented in this table is from testing done between Jan 1-Dec 31, 2007. We monitor for some contaminants less than once per year, and for those contaminants, the date of the last sample is shown in the table.
** We meet the TT requirement for Total Organic Carbon. We were required to remove 25.83% and average removal was 49.44%.
Abbreviations · CCR: Consumer Confidence Report · ppb: parts per billion or micrograms per liter · ppm: parts per million or milligrams per liter · N/A: not applicable · NTU: Nephelometric Turbidity Unit, used to measure cloudiness in drinking water · pCi/l picocuries per liter (a measure of radioactivity) · AL: Action Level, or the concentration of a contaminant which, when exceeded, triggers treatment or other requirements which a water system must follow.. · TT: Treatment Technique or a required process intended to reduce the level of a contaminant in drinking water. · MRDL or Maximum Residual Disinfectant Goal: The highest level of a disinfectant allowed in drinking water. · MRDLG or Maximum Residual Disinfectant Level Goal: The level of a drinking water disinfectant below which there is no known or expected risk to health.
1. Lead and copper values are reported in 90th percentile values. During the most recent round of lead and copper testing, 0 out of 30 households tested contained concentrations exceeding the action level.
