Northeast Knox Utility District is pleased to present to its customers this years Water Quality Report. This report is designed to inform the customer about the quality water and services Northeast Knox Utility District delivers to the customer everyday, and is prepared in cooperation with the Environmental Protection Agency and the Tennessee Department of Environment and Conservation Division of Water Supply. Northeast Knox Utility District's goal is to provide the customer a safe and dependable supply of drinking water. The utility is again proud of the fact that it has met state and federal drinking water standards. Northeast Knox Utility District will be making improvements to the distribution system in the near future to better serve you. Northeast Knox Utility District is committed to ensuring the quality of its customers water and would like its customers to be informed about their water quality. We Ask our customers to please make sure a cut-off valve is installed on your line. We also ask that you use care not to damage the automated meter and equipment. If you have any questions concerning this report please call Gregg Morgan at 687-5345 or Jamie Smith at 525-0782. Northeast Knox Utility District's Board of Commissioners meetings are held at its office at 7214 Washington Pike on the 4th Monday of each month, starting at 8:30AM. Please feel free to participate in these meetings. Vacancies on the Board of Commissioners of the Northeast Knox Utility District are filled by the certification of a list of three nominees to fill the vacancy with the Knox County Mayor. The Knox County Mayor appoints one of these three nominees to fill the vacancy. If the Knox County Mayor does not appoint one of the nominees from the Board's list of three nominees, the Knox County Mayor enters an order rejecting the three nominees. The Board of Commissioners continues to certify additional lists of three nominees to the Knox County Mayor until an appointment is made from such additional lists. Decisions by the Board of Commissioners on customer complaints brought before the Board of Commissioners under the District's customer complaint policy may be reviewed by the Utility Management Review Board of the Tennessee Department of Environment and Conservations pursuant to Section 7-82-707(7) of Tennessee Code Annotated.

The following Water Quality Data table shows the results of Northeast Knox Utility District's monitoring for the period of January 1, thru December 31, 2009. In the table the customer will find many terms and abbreviations. To help better understand these terms Northeast Knox Utility District has provided the following definitions. Turbidity - Turbidity does not present any risk to your health. We monitor turbidity, which is a measure of the cloudiness of water, because it is a good indicator that our filtration system is functioning properly. (nd) - non-detects - laboratory analysis indicates that the constituent is not present. (ppm) - parts per million or (mg/1) milligrams per liter - one part per million corresponds to one minute in 2 years or a single penny in $10,000. (ppb) - parts per billion or micrograms per liter - one part per billion corresponds to one minute in 2,000 years or a single penny in $10,000,000. (pCi/l) - picocuries per liter - A measure of radioactivity in water. (mrem/yr) - millirems per year - a measure of radiation absorbed by the body. (MFL) - million fibers per liter - A measure of the presence of asbestos fibers that are no longer than 10 micrometers. (NTU) - Nephelometric Turbidity Unit - A measure of the clarity of water. Turbidity of 5NTU is just noticeable to the average person. (AL) - Action Level - The concentration which, if exceeded, triggers treatment or other requirements which water systems must follow. (TT) - Treatment Technique - A required process intended to reduce the level of a contaminant in drinking water. (MCL) - Maximum Contaminant Level – or the highest level of contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology. (MCLG) - Maximum Contaminant Level Goal - The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLG's allow for a margin of safety. (MRDLG) - Maximum Residual Disinfectant Level Goal, or 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. (MRDL) – Maximum Residual Disinfectant Level, or the level of disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for the control of microbial contaminants. (BDL) - Below Detectable Limit (P/A) - Presence or Absence of a Contaminant Unless otherwise noted the data presented in this table is from sampling performed during the 2009 calendar year About the data: Northeast Knox Utility District monitors for some contaminants less than once per year, and for those contaminants, the date of the last sample is shown in the table. 250 bacteria samples were taken in the district distribution system. Two separate months had one sample reported positive for Total Coliform, a bacteria that is naturally present in the environment and is used as an indicator that other, potentially harmful bacteria may be present. Northeast Knox Utility District monitored regulated and unregulated volatile organic chemicals four separate quarters throughout the calendar year 2009. All results are within compliance level or below detectable levels. Northeast Knox Utility District has been granted waivers for all synthetic organic monitoring by the state except atrazine, which was sampled in 2008 and found to be <0.1 ppb with the MCL set at 3.0 ppb. 18 Inorganics sampled in 2008 were within compliance levels or below detectable limits. All sample records, including regulated, unregulated, special unregulated chemical monitoring, special chemical monitoring, and any other water quality reports, are available for viewing during normal business hours with an appointment. Water Quality Data Table
1- 1,814 Turbidity samples were analyzed in 2009, we met the treatment technique for turbidity with 100% of our samples below the turbidity limit of .30 NTU.
3- Northeast Knox Utility District met the treatment technique requirements for TOC in Calendar year 2009.
4-Range of detections are lowest individual value to highest individual value reported in 2009 from stage 1 and standard monitoring samples. Level detected is the highest running annual average for 2009. 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 systems and may have increased risk of getting cancer.
5- Laboratory detection limit 2 ppb.
6–Northeast Knox completed E.P.A. mandated cryptosporidium monitoring in September of 2009. Cryptosporidium is a microbial parasite which is found in surface water throughout the U.S. Although Cryptosporidium can be removed by filtration, the most commonly used filtration methods cannot guarantee 100 percent removal. Monitoring of our source water indicated the presence of cryptosporidium in 2 out 9 of samples tested in 2009. Symptoms of infection include nausea, diarrhea, and abdominal cramps. Most healthy individuals are able to overcome the disease within a few weeks. However, immune-compromised people have more difficulty and are at greater risk of developing severe, life threatening illness. Immuno-compromised individuals are encouraged to consult their doctor regarding appropriate precautions to take to prevent infection. For more information on Cryptosporidium, contact the Safe Drinking Water Hotline (800-426-4791).
