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, 2016. 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 2016 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.
300 bacteria samples were taken in the distribution system in 2016 with 0 Total Coliform MCL violations. Total Coliform is a bacteria 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 2015. All results are within compliance level or below detectable levels.
Northeast Knox Utility District sampled eight Synthetic Organic Compounds in 2016 including Alachlor, Atrazine, Metolachlor, Simazine, Aldicarb, Carbofuran, Glyphosate, and 2,4-D. All were found to be below detectible limits.
25 Inorganics sampled in 2011 were within compliance levels or below detectable limits. (see footnote number 6).
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.

1 - 1,753 Turbidity samples were analyzed in 2016 with an annual average of 0.05 NTU, Northeast Knox Utility met the treatment technique for turbidity with 100% of our samples below the turbidity limit of 0.30 NTU.
2 - Lead and Copper samples only required every 3 years. 30 samples from various points in the distribution system. 0 sites of 30 exceeded Action level. "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. Northeast Knox Utility District 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"
3 - Northeast Knox Utility District met the treatment technique requirements for TOC in Calendar year 2016.
4 - Laboratory detection limit 1.0 ppb.
5- Some people who drink water containing trihalomethanes in excess of tht MCL over many years may experience problems with their liver, or central nervous systems, and may have an increased risk of getting cancer. LRAA= Location Running Annual Average.
6 - Sulfate and Arsenic are amoung 26 inorganic chemicals waived in the Jan. 1, 2014 through Dec. 31, 2016, sampling cycle.
7 - Northeast Knox started E.P.A. mandated crytosporidium monitoring in October 2016. 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% removal. Monitoring of our source water indicated the presence of cryptosporidium in 2 out of 3 samples tested in 2016. Symptons 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 illiness. 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).
8 -Important information about your drinking water. Monitoring requirements not met for Northeast Knox Utility. Our water system violated drinking water standards over the past year. Even though these were not emergencies, as our customers, you have the right to know what happened and what we did to correct these situations. We are required to monitor your drinking water for specific contaminants on a regular basis. Results of regular monitoring are an indicaor of whether or not our drinking water meets health standards. During 1/1/08-12/31/2016 compliance period we did not monitor Gross Alpha, Radium 226, or Radium 227 and therefore cannot be sure of the quality of our drinking water during that time. What should I do? There is nothing you need to do at this time. The table below lists the contaminants we did not properly test for during the last year, how ofter we are supposed to sample for these contaiminants and how many samples we are supposed to take, how many samples we took, when samples should have been taken, and the date of which follow-up samples were taken.
When samples should
have been taken
1 sample between
2008 and 2016
What is being done? The Utility has taken the required samples on 2/13/2017 that presented normal or below detection limit. For more information, please contact Jamie Smith at 865-525-0782, or mail to Northeast Knox Utility, 7214 Wastington Pike, Corryton, TN 37721.
Please share this information with all the other people who drink this water, especially those who may not have received this notice directly (for example, people in apartments, nursing homes, schools, and businesses). You can do this by posting this notice in a public place or distributing copies by hand or mail.
This annual drinking water quality report and notice is being sent to you by Northeast Knox Utility District, State Water System #TN0000515. Distributed May 19,2017.
Northeast Knox Utility District
Northeast Knox Utility District's water treatment plant is capable of producing 6,912,000 gallons per day for its' customers in Northeast Knox County and also provides water to Luttrell-Blaine-Corryton Utility District and to the City of Maynardville, TN. The plant draws its water from the Holston River and uses conventional treatment techniques.
Your water, which is surface water, comes from the Holston River. Our goal is to protect the 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 source 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 Northeast Knox Utility District Water System source is 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 www.tn.gov/environment/dws/dwassess.shtml or you can call TDEC EAC at 1-888-891-8332 or you may contact the Water System to obtain copies of specific assessments.
Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. Community water systems are required to disclose the detection of contaminants; however, bottled water companies are not required to comply with this regulation. The presence of contaminates 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).
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, can be picked up substances resulting from the presence of animals or from human activity. Contaminants that may be present in source water:
In order to ensure that tap water is safe to drink, EPA and Tennessee Department of Environment and Conservation prescribe regulations which limit the amount of certain contaminants in water provided by the public water systems. FDA regulations establish limits for contaminants in bottled water which must provide the same protection for public health.
Some people may be more vulnerable to contaminants in drinking water than the general population. Immunocompromised 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).
The State and EPA require Northeast Knox Utility District to test and report on its water on a regular basis to ensure safety. Northeast Knox Utility District has met all of these requirements and would like the customer to know we observe all the rules and regulations set forth by the Tennessee Department of Environment and Conservation and the EPA. Northeast Knox Utility District scored a 100.0 on its most recent sanitary survey by the Tennessee Department of Environment and Conservation.
Northeast Knox Utility District works around the clock to provide top quality water to every tap. The utility asks that all its customers help to protect the water sources, which are the heart of the community, the way of life, and the children's future.
