additional information, please contact us at 660-327-4334.
SOURCE
OF DRINKING WATER- The City of
Paris
purchases all water from the MO2020421 Clarence Cannon Wholesale Water
Commission. The water source for the CCWWC is
Mark
Twain
Lake
located in
Monroe
and
Ralls Counties
,
Missouri
.
Mark
Twain
Lake
is a surface water reservoir owned and operated by the U.S. Army Corps of
Engineers. The sources of drinking water (both tap water and bottled
water) include rivers, lakes, streams, ponds, reservoirs, springs, and
groundwater 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, and can pick up substances resulting from the
presence of animals or from human activity. The Department of Natural
Resources conducted an assessment of our source water to determine its
susceptibility to contaminations. All surface water sources are
vulnerable to land use activities within their watershed. This is why
all surface water in
Missouri
must be treated in dual treatment trains with barriers in place for
potential microbiological and chemical contaminants. The assessment is
a delineation of our watershed(s) and an inventory of the potential
contaminants found within the watershed(s). If you want to know more
about the assessment or wish to participate on a watershed protection team
to protect this valuable resource, then please call 573-672-3237.
INFORMATION
ON WATER QUALITY – 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. 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).
Contaminants
that may be present in source water include:
A.
Microbial contaminants, such as viruses and
bacteria, which may come from sewage treatment plants, septic systems,
agricultural livestock operations, and wildlife.
B.
Inorganic contaminants, such as salts and
metals, which can be naturally-occurring or result from urban stormwater
runoff, industrial, or domestic wastewater discharges, oil and gas
production, mining, or farming.
C.
Pesticides and herbicides, which may come from a
variety of sources such as agriculture, urban stormwater runoff, and
residential uses.
D.
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.
E.
Radioactive contaminants, which can be naturally
occurring or be the result of oil and gas production and mining activities.
In
order to ensure that tap water is safe to drink, the Department of Natural
Resources prescribes regulations which limit the amount of certain
contaminants in water provided by public water systems.
Department of Health 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 from
infection. These people should
seek advice about drinking water from their healthcare providers.
Environmental Protection Agency/Centers for Disease Control
guidelines on appropriate means to lessen the risk of infection by
Cryptosporidium and other microbial contaminants are available from the Safe
Drinking Water Hotline (800-426-4791).
If you would
like be observe the decision-making process that affects drinking water
quality or if you have any further questions about your drinking water
report, please call us at 660-327-4334 to inquire about scheduled meetings
or contact persons.

Definitions:
(1)
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. MCLG’s allow for a margin of safety.
(2)
MCL:
Maximum Contaminant Level, or the highest level of a contaminant that is
allowed in drinking water. MCL’s
are set as close to the MCLG’s as feasible
using the best available treatment technology.
(3)
TT :
Treatment Technique, or a required process intended to reduce the
level of a contaminant in drinking water.
(4)
AL
: Action Level, or the
concentration of a contaminant which, when exceeded, triggers treatment or
other requirements which a water system must follow.
(5)
90th
percentile: For lead and copper testing.
10% of test results are above this level and 90% are below this
level.
(6)
Level
Found: is the average of all
test results for a particular contaminant.
(7)
Range
of
Detection
: Shows the lowest and highest
levels found during a testing period, if only one sample was taken, then
this number equals the level found.
(8)
MRLDG:
Maximum Residual Disinfectant Level Goal, or the level of a drinking water
disinfectant below which there is no known or expected risk to health.
(9)
MRDL:
Maximum Residual Disinfectant Level, or the highest level of a disinfectant
allowed in drinking water.
Abbreviations:
(1)
ppb: parts
per billion or micrograms per liter.
(2)
ppm:
parts per million or milligrams per liter.
(3)
n/a: not
applicable.
(4)
ntu:
Nephelometric Turbidity Unit, used to measure
cloudiness in drinking water.
(5)
mfl:
million fibers per liter, used to measure asbestos concentration.
(6)
nd:
not detectable at testing limits.
The
state has reduced monitoring requirements for certain contaminants to less
often than once per year because of these contaminants are not expected
to vary significantly from year to year.
Records with a sample year more than one year old are still
considered representative.
