NORRIS WATER COMMISSION 2012 Water Quality Report
Is my drinking water safe?
Norris Water Commission is proud to report
to the public that our drinking water is safe and meets all State and Federal standards.
What
is the source of my water?
Norris Water Commission's Water Treatment Plant source is the Clear Creek Spring,
a ground water source that is protected by 2700 acres of Watershed area.
The
Norris Water Commission / Water System
Source rated as moderately susceptible to potential contamination.
The assessment summaries can be viewed online at www.tn.gov/environment/dws/dwassess.shtml
or you may contact
the water system to obtain copies of specific assessments.
Wellhead Protection:
The Tennessee Division of Water Supply has approved the Norris Water Commission Wellhead Protection Plan. A certificate
for successfully completing all submittals for implementation in protecting our ground water source. The Wellhead Protection
Plan is available for public review at the Norris City Office. If you have any questions, please contact Tony Wilkerson,
Water Manager at (865) 494-7645.
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. Your source of drinking water (both tap water and bottled
water) includes rivers, lakes, streams, ponds, reservoirs, springs and wells.
More information about contaminants
and potential health effects can be obtained by calling the Environmental Protection Agency Safe Drinking Water Hotline (800-426-4791).
Statement - 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. Norris Water Commission 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 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 at http://www.epa.gov/safewater/lead."
How can I get involved?
Norris Water Commission, Board of
Commissioners meets on the third Monday of each month at 12:00 Noon at the Norris Community Building, 20 Chestnut Drive, Norris,
TN.
Is our water system meeting other rules that govern our operations?
The State of Tennessee, Division of Water Supply, and EPA requires drinking water providers to test and report on
our water on a regular basis to ensure safety and water quality. Norris Water Commission meets the requirements set
forth by the regulatory agencies. Norris Water Commission and the employees respect the regulatory requirements and
work extremely hard to observe all rules and regulations governing water treatment and distribution operation on a daily basis.
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 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).
Water System Security
Following the events of September 11, 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, tanks, fire hydrants, etc.
To the Norris City Office (865) 494-7645 or the Norris Public Safety Department
(865) 494-0880.

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.

action level.
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.
No more than 5% of the samples exceeded the 0.3 standard.
Abbreviations: · 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 · MFL: million fibers per liter,
used to measure asbestos concentration. · 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. BDL-Below Detection Limit
· ND: Not Detected
About the data: Most of the data presented in this table is from testing
done between January 1 and December 31, 2012. 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.
Lead/Copper No sample exceeded the
action level
TTHM: Norris Water Commission completed quarterly monitoring in 2005 and qualified for
reduce monitoring -(1) sample per treatment plant per year.
MRDL: Maximum 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 disinfections to control microbial contaminants.
