Water Quality Report
for 2008

The Dunlap Water System is pleased to present you with our annual water quality report. The report is designed to raise awareness of where our water comes from, understand treatment processes, and educate on source water protection.  This will allow you, the consumer to make informed decisions about your drinking water. More information can be obtained from Philip Roberson at 949.3121 or E.P.A.'s Safe Drinking Water Hotline at 1.800.426.4791

Where Does Our Water Come From?

Source Water Assessment

The Tennessee Department of Environment and Conservation has prepared a Source Water Assessment Program Report for untreated water sources. The 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 based on geological factors and human activities in the vicinity of the water source. Our rating is moderately susceptible. An explanation of the Tennessee Source Water Assessment Program, the Source Water Assessment summaries, susceptible scorings and the overall TDEC report to EPA can be viewed at http://tennessee.gov/environment/dws/dwassess.shtml or you may contact the water system to obtain copies of specific assessments. 

For Your Information

Public Participation

The Dunlap Water System conducts monthly business during regular City Commission Meetings which are scheduled the 1st Thursday of each month at 6:00pm.




The Dunlap Water System routinely monitors for constituents in your drinking water according to Federal and State laws. The following table shows the results of our monitoring for the period of January 1st to December 1st, 2008 unless otherwise posted. All drinking water, including bottled drinking water, may be reasonably expected to contain at least small amounts of some constituents. It's important to remember that the presence of these constituents does not necessarily pose a health risk.

• 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 transplant, people with HIV/AIDS or other immune system disorders, some elderly, and infants can be particularly at risk from infections.
• These people should seek advise from their health care providers about drinking water. 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 1.800.426.4791.

Lead..

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. The Dunlap Water System 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/safewater/lead 

The Bottom Line......

The Dunlap Water System water quality meets and exceeds State and Environmental Protection Agency standards.

Test Results

We met the treatment technique for turbidity with 100% of the monthly samples below the turbidity limit of 0.3 NTU. We monitor turbidity, we monitor turbidity, which is a measurement of the cloudiness of water, because it is a good indicator the filtration system is functioning well.

* 0 out of 20 site sampled had a level exceeding the lead and copper action level.

** The treatment technique for total carbon was met at 100% in 2008

Some people who drink water containing trihalomethanes in excess of the MCL over many years may experience problems with their liver, kidneys, or central nervous system, and may have an increased risk of getting cancer.

Parts Per Million (ppm) or Milligrams Per Liter (mg/l)
    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
    One part per million corresponds to one minute in 2,000 years, or a single penny in $ 10,000,000.

Picouries Per Liter (pCi/L)
    Picouries per liter is a measurement of the radioactivity in water.

Nephelometric Turbidity Unit (NTU)
    Nephelometric turbidity unit is a measurement of clarity of water. Turbidity in excess of 5 NTU is just noticeable
to the average person.

Action Level (AL)
    The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water
system must follow.

Treatment Technique (TT) - (mandatory language)
    A treatment technique is a required process intended to reduce the level of a contaminant in drinking water.

Maximum Contaminant Level - (mandatory language)
    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 - (mandatory language)
    The "Goal" (MCGL) is the level of a contaminant in drinking water below which there is no known or expected
risk to health. MCGLs allow for a margin of safety.
