Details for City of Madisonville Water Quality Report 2014

City of Madisonville Water Quality Report 2014
Yes, our water meets all of EPA’s health standards. We have conducted
numerous tests for over 80 contaminants that may be in drinking water.
As you’ll see in the chart on the back, we only detected 10 of these
contaminants. We found all of these contaminants at safe levels.
Your water, which is purchased surface water from Tellico Area Ser-
vice System (TASS), comes from Tellico Lake. 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 contami-
nation. 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 City of Madiosnville 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
environment/dws/dwassess.shtml 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 contaminates. The presence
of contaminates does not necessarily indicate that water poses a health
risk. More information about contaminates and potential health affects
can be obtained by calling the Environmental Protection Agency’s Safe
Drinking Water Hotline. (800-426-4791).

Our Water Board meets on the first Monday of each month at 6:00 p.m.
at City Hall located at 400 College Street, Madisonville. Please feel
free to participate in the meetings.
The State and EPA require us to test and report on our water on a regu-
lar 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.
The sources of drinking water (both tap water and bottled wter) 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-occuring 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 live-
stock operations, and wildlife.
• Inorganic contaminants, such as salts and metals, which can be
naturally-occuring or result from urban stormwater runoff, industrial,
or domestic wastewater discharges, oil and gas production, mining, or
• Pesticides and herbicides, which may come from a variety of sourc-
es 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-occuring 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 Tennes-
see Department of Environment and Conservation prescribe regulations
which limit the amount of certain contaminants in water provided by
public water systems. TASS 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.
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 transplants, people with HIV/AIDS or other immune
system disorders, some elderly and infants can be particularly at risk
for 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 Cryp-
tosporidium and other microbiological contaminates are available from
the Safe Drinking Water Hotline (800-426-479l).
If present, elevated levels of lead can cause serious health problems, es-
pecially for pregnant women and young children. Lead in drinking water
is primarily from materials and components associated with service lines
and home plumbing. City of Madisonville is responsible for providing
high quality drinking water, but cannot control the varierty of materials
used in plumbing components. When your water has been sitting for
several hours, you can minimize the potential for lead exposure by flush-
ing 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
Following the events of September 2001, we realize that our custom-
ers 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
Water Quality Data
MCLG - Maximum contaminate Level Goal, or 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.
MCL - Maximum Contaminate Level, or the highest level of a con-
taminant 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.
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 disin-
fectants to control microbial contaminates.
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.
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.
1100% of our samples were below the turbidity limit. Turbidity is a measure of the cloudiness of the water. 2During the most re-
cent round of Lead and Copper testing, only 0 out of 30 households sampled contained concentrations exceeding the action level.
3We met all treatment technique requirements for Total Organic Carbon removal.
