ANNUAL REPORT ON WATER QUALITY (Consumer Confidence Report)
MO2010624
This
Annual Water Quality Report is presented to customers of the City of Paris, MO
and interested parties. This
report details the quality of water delivered to users, the efforts made to
provide safe drinking water and other information of interest.
If you have any questions about the information presented or need
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 CCWWC has entered into a contract with the Corps and the
state of
Missouri
for purchase of water storage space in
Mark
Twain
Lake
. The reservoir has a total of 16 million gallons of raw water per day
available for drinking water purposes. Current production average 4.0
millions of gallons per day. 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.
INFORMATION
ON WATER QUALITY – 2006
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).
The
Missouri Department of Natural Resources regulates our water system and
requires us to test our water on a regular basis to ensure its safety.
Our system has been assigned the identification number MO2010624 for
the purpose of tracking our test results.
Last year, we tested for a variety of contaminants.
The detectable results of these tests are on the following pages of
this report. Any violations of
state requirements or standards will be further explained later in the report.
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.
