Town of Oliver Springs 2016 Water Quality Report

Town of Oliver Springs Water Quality Report 2016


Is my drinking water safe?    

Yes, our water meets all of EPAs health standards. We have conducted numerous tests for over 80 contaminants that may be in drinking water.  As youll see in the chart on the back, we only detected 8 of these contaminants.  We found all of these contaminants at safe levels.       

What is the source of my water?

 Your water comes from Bacon Spring and surface water from the Clinch River purchased from the Anderson County Water Authority. Our goal is to protect our water from contaminants 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 serving this water system.  The SWAP Report assesses the susceptibility of 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, moderately susceptible or slightly susceptible based on geologic factors and human activities in the vicinity of the water source.  The Town of Oliver Springs sources rated as reasonably susceptible to potential contamination.

An explanation of Tennessee’s Source Water Assessment Program, the Source Water Assessment summaries, susceptibility scorings and the overall TDEC report to EPA can be viewed online at  https://www.tn.gov/environment/article/wr-wq-source-water-assessment or you may contact the Water System to obtain copies of specific assessments.

Why are there contaminants in my 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 Agencys Safe Drinking Water Hotline (800-426-4791).                            

Este informe contiene información muy importante.  Tradúscalo o hable con alguien que lo entienda bien.

For more information about your drinking water, please call us at the Oliver Springs Water Treatment Plant at (865) 457-4298.    

How can I get involved?

Our Water Board meets on the first Thursday each month at 6:30pm,at city hall located at 717 Main Street.  Please feel free to participate in these meetings.

Is our water system meeting other rules that govern our operations?

 The State and EPA require us to test and report on our water on a regular basis to ensure its safety. We have met all of these requirements.  Results of unregulated contaminant analysis are available upon request.  We want you to know that we pay attention to all the rules.

Other Information

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:

· Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.

· 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.

· Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses.

· 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.

· 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, EPA and the Tennessee Department of Environment and Conservation prescribe regulations which limit the amount of certain contaminants in water provided by public water systems. Town of Oliver Springs's water treatment processes are designed to reduce any such substances to levels well below any health concern.  FDA regulations establish limits for contaminants in bottled water which must provide the same protection for public health.

Do I Need To Take Special Precautions?

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 under-gone 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 not only their drinking water, but food preparation, personal hygiene, and precautions in handling infants and pets 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).

Lead 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. Town of Oliver 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/lead/protect-your-family%23water%23water

 

Water System Security

Following the events of September 2001, we realize that our customers are concerned about the security of their drinking water.  We urge the public to report any suspicious activities at any utility facilities, including treatment plants, pumping stations, tanks, fire hydrants, etc. to 865-457-4298

Pharmaceuticals In Drinking Water

Flushing unused or expired medicines can be harmful to your drinking water.  Learn more about disposing of unused medicines at  https://www.tn.gov/environment/article/sp-unwanted-pharmaceuticals

What does this chart mean?

  • MCLG -  Maximum Contaminant Level Goal, or 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.
  • MCL - Maximum Contaminant Level, or 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. 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.
  • MRDLMaximum 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 the control of microbial contaminants.
  • MRDLG: Maximum residual disinfectant level goal.  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.
  • AL - Action Level, or the concentration of a contaminant which, when exceeded, triggers treatment or other requirements which a water system must follow.
  • Below Detection Level (BDL) - laboratory analysis indicates that the contaminant is not present at a level that can be detected.
  • Non-Detects (ND) - laboratory analysis indicates that the contaminant is not present.
  • Parts per million (ppm) or Milligrams per liter (mg/l) – explained as a relation to time and money as one part per million corresponds to one minute in two years or a single penny in $10,000.
  • Parts per billion (ppb) or Micrograms per liter - explained as a relation to time and money as one part per billion corresponds to one minute in 2,000 years, or a single penny in $10,000,000.
  • Million Fibers per Liter (MFL) - million fibers per liter is a measure of the presence of asbestos fibers that are longer than 10 micrometers.
  • Nephelometric Turbidity Unit (NTU) - nephelometric turbidity unit is a measure of the clarity of water. Turbidity in excess of 5 NTU is just noticeable to the average person.
  • TT - Treatment Technique, or a required process intended to reduce the level of a contaminant in drinking water.
  • RTCR – Revised Total Coliform Rule.  This rule went into effect on April 1, 2016 and replaces the MCL for total coliform with a Treatment Technique Trigger for a system assessment

*During the most recent round of Lead and Copper testing,  0 out of 20 households sampled contained concentrations exceeding the action level.1100% of our samples were below the turbidity limit.  Turbidity is a measure of the cloudiness of the water. We monitor it because it is a good indicator of the effectiveness of our filtration system. In June of 2016  we received a notice of violation for turbidity due to a failure to monitor. At no time was the mcl for turbidity exceeded. In December of 2016 we received a notice of violation for total coliform bacteria. We are required to take 6 bacteriological samples monthly. For the month of December we only submitted 3 samples. At no time was there any positive samples

Turbidity. Turbidity has no health effects. However, turbidity can interfere with disinfection and provide a medium for microbial growth. Turbidity may indicate the presence of disease-causing organisms. These organisms include bacteria, viruses, and parasites that can cause symptoms such as nausea, cramps, diarrhea, and associated headaches.
