SHAWNEE CO RWD 8
Confidence Report – 2018
Calendar Year – 2017
brochure is a snapshot of the quality of the water that we provided last
year. Included are the details about
where your water comes from, what it contains, and how it compares to
Environmental Protection Agency (EPA) and state standards. We are committed to providing you with information
because informed customers are our best allies. If you would like to observe
the decision-making process that affect drinking water quality, please call

drinking water is supplied from another water system through a Consecutive
Connection (CC). Your water comes from :

people may be more vulnerable to contaminants in drinking water than the
general population. Immuno-compromised persons such as those 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 infections. These people should seek advice about
drinking water from their health care providers. EPA/CDC 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).
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 EPA’s
Safe Drinking Water Hotline (800-426-4791).
sources of drinking water (both tap water and bottled water) included rivers,
lakes, streams, ponds, reservoirs, springs, and 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.
that may be present in sources water before we treat it include:
such as viruses and bacteria, which may come from sewage treatment plants,
septic systems, livestock operations and wildlife.
such as salts and metals, which can be naturally-occurring or result from urban
storm water runoff, industrial or domestic wastewater discharges, oil and gas
production, mining or farming.
which may come from a variety of sources such as storm water run-off,
agriculture, and residential users.
which can be naturally occurring or the result of mining activity.
Organic contaminants, including
synthetic and volatile organic chemicals, which are by-products of industrial
processes and petroleum production, and also come from gas stations, urban
storm water run-off, and septic systems.
order to ensure that tap water is safe to drink, EPA prescribes regulation
which limits the amount of certain contaminants in water provided by public
water systems. We treat our water according to EPA’s regulations. Food and Drug
Administration regulations establish limits for contaminants in bottled water,
which must provide the same protection for public health.
water system is required to test a minimum of 7 samples per month in accordance
with the Total Coliform Rule for microbiological contaminants. Coliform
bacteria are usually harmless, but their presence in water can be an indication
of disease-causing bacteria. When coliform bacteria are found, special
follow-up tests are done to determine if harmful bacteria are present in the
water supply. If this limit is exceeded, the water supplier must notify the
following tables list all of the drinking water contaminants which were
detected during the 2017 calendar year. The presence of these contaminants does
not necessarily indicate the water poses a health risk. Unless noted, the data presented in this
table is from the testing done January 1- December 31, 2017. The state requires us to monitor for certain
contaminants less than once per year because the concentrations of these
contaminants are not expected to vary significantly from year to year. Some of the data, though representative of
the water quality, is more than one year old. The bottom line is that the water that is
provided to you is safe.
Contaminant Level Goal (MCLG): the “Goal” is the level of a contaminant in drinking water below
which there is no known or expected risk to human health. MCLGs allow for a margin of safety.
Contaminant Level (MCL): the
“Maximum Allowed” MCL is 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.
Maximum Contaminant Level (SMCL): recommended level for a contaminant that is
not regulated and has no MCL.
Level (AL): the
concentration of a contaminant that, if exceeded, triggers treatment or other
Technique (TT): a
required process intended to reduce levels of a contaminant in drinking water.
Residual Disinfectant Level (MRDL): the highest level of a disinfectant allowed in drinking water.
There is convincing evidence that addition of a disinfectant is necessary for
control of microbial contaminants.
analysis indicates that the contaminant is not present.
per Million (ppm) or milligrams per liter (mg/l)
per Billion (ppb) or micrograms per liter (µg/l)
per Liter (pCi/L): a
measure of the radioactivity in water.
per Year (mrem/yr):
measure of radiation absorbed by the body.
Monitoring Period Average (MPA): An average of sample results obtained during a defined time frame,
common examples of monitoring periods are monthly, quarterly and yearly.
Turbidity Unit (NTU): a
measure of the clarity of water.
Turbidity in excess of 5 NTU is just noticeable to the average
person. Turbidity is not regulated for
Running Annual Average (RAA): an
average of sample results obtained over the most current 12 months and used to
determine compliance with MCLs.
