Is my drinking water saafe?
W have conductted
Yes, oour water meets all of EPA’s heealth standards. We
numeroous tests for over 80 contaminants that may be in drinking water. As
you’ll see in the chart on
o the back, we only detected 9 of these contaminannts.
We fouund all of these coontaminants at safe levels.

(TDEC

for the untreated water sources serving thhis water system. The SWAP Repport
assessses the suscepptibility of untreaated water souurces to potenttial

Why aare there contamiinants in my wateer?
Drinkinng water, includingg bottled water, may reasonably be expected to contaain
at leasst small amounts of
o some contaminnants. The presennce of contaminannts
does nnot necessarily inddicate that water poses
p
a health risk. More informatiion
about contaminants andd potential health effects
e
can be obttained by calling the
t
Environmental Protectioon Agency’s Saffe Drinking Wateer Hotline (800-42264791).

Microbial contaminnants, such as viruuses and bacteria, which may come
frrom sewage treatm
ment plants, septicc systems, agriculltural livestock
ooperations, and willdlife.
· Innorganic contaminnants, such as saltts and metals, which can be
n aturally-occurring or result from urbban stormwater runnoff, industrial, or
d omestic wastewatter discharges, oil and gas production, mining, or
faarming.
·P
Pesticides and herrbicides, which maay come from a vaariety of sources
s uch as agriculturee, urban stormwateer runoff, and residential uses.
Organic chemical ccontaminants, including synthetic annd volatile organicc
·O
c hemicals, which aare by-products of industrial processses and petroleum
m
pproduction, and ca n also come from gas stations, urbaan stormwater
ruunoff, and septic ssystems.
·R
Radioactive contam
minants, which cann be naturally-occcurring or be the
reesult of oil and gass production and m
mining activities.
In order to ensure that tapp water is safe to ddrink, EPA and thee Tennessee
Departm
ment of Environmeent and Conservattion prescribe reguulations which limit
the amoount of certain contaminants in wateer provided by pubblic water systems.
Maynarddville Water Systeem's water treatmeent processes are designed to
reduce aany such substancces to levels well bbelow any health cconcern. FDA
regulatioons establish limitss for contaminantss in bottled water w
which must
provide tthe same protectioon for public healtth.
Do I Neeed To Take Speccial Precautions??
Some peeople may be moore vulnerable to contaminants in ddrinking water than
the geneeral population. IImmuno-comprom

cancer undergoing chem
motherapy, persoons who have under-gone organ
transpla nts, people with HIV/AIDS or otheer immune system

How ccan I get involved

Water Board meetss on the second Tuesday of each month
m
at 7:00 p.m. at
City Haall, 125 Johnson Rd.
R Please feel freee to participate inn these meetings.
Lead in Drinking Water
If presennt, elevated levelss of lead can causee serious health pproblems,
especiallly for pregnant woomen and young cchildren. Lead in ddrinking water is
primarilyy from materials annd components asssociated with serrvice lines and
home pl umbing. The Mayynardville Water Syystem is responsibble for providing
materials used in
high quaality drinking waterr, but cannot control the variety of m
plumbingg components. W
When your water haas been sitting for several hours, you
can miniimize the potentiaal for lead exposurre by flushing yourr tap for 30
secondss to 2 minutes befoore using water foor drinking or cooking. If you are
concerneed about lead in yyour water, you maay wish to have yoour water tested.
Informattion on lead in drinnking water, testing methods, and steps you can take
to minim
mize exposure is avvailable from the S
Safe Drinking Watter Hotline or at

Is our water system meeeting other ruless that govern our operations?
The S
State and EPA require us to test and
a report on ourr water on a reguular
basis tto ensure its safetty. We have met all of these requirrements. Results of
unreguulated contaminannt analysis are avaailable upon requeest. We want youu to
know tthat we pay attentiion to all the rules.
Water S
System Security
Followinng the events of Seeptember 2001, w
we realize that our customers are
concerneed about the secuurity of their drinkinng water. We urge the public to
report anny suspicious activvities at any utilityy facilities to 992-33821.

Other Information
The soources of drinking water (both tap water and bottled water)
w
include riverrs,
lakes, streams, ponds, reservoirs,
r
springss, and wells. As waater travels over thhe
surfacee of the land or thrrough the ground, it dissolves naturally-occurring
mineraals and, in some caases, radioactive material, and can pick up substancees
resultinng from the presennce of animals or from human activity.
Pharmaaceuticals In Drinnking Water
Flushinng unused or exppired medicines ccan be harmful tto your drinking
water. Learn more aboout disposing of uunused medicinees at

Q u a l i t y
D a t a
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. 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 disinfectants to control microbial contaminants.

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
%

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.

RTCR – Revised Total Coliform Rule. This rule went into effect on April 1, 2016 and replaces the MCL for total coliform with a Treatment
Technique Trigger for a system assessment.

99.4% of our samples were below the turbidity limit. Turbidity is a measurement of the cloudiness of water. 2During the most recent
round of Lead and Copper testing 0 out of 20 households sampled contained concentrations exceeding the action level for lead or
copper. 3Water purchased from Northeast Knox Utility District met the treatment technique requirements for TOC during the calendar
year of 2015. 4 Alpha emitters. Certain minerals are radioactive and may emit a form of radiation known as alpha radiation. Some
people who drink water containing alpha emitters in excess of the MCL over many years may have an increased risk of getting cancer.
