We're pleased to present to you this year's
Annual Quality Water Report. This report is designed to inform you about the
quality water and services we deliver to you every day. Our constant goal is to
provide you with a safe and dependable supply of drinking water. We want you to
understand the efforts we make to continually improve the water treatment
process and protect our water resources. We are committed to ensuring the
quality of your water.
What is the source of our water?
The sources of drinking water, both tap and
bottled water, 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 occurring minerals and, in some cases radioactive material
and can pick up substances resulting from the presence of animals or from human
activity. Our water source is ground water. We have 14 deep wells that range in depth
from 1000 ft. to 1868 feet deep at various locations in and around the city.
The Department of Natural Resources conducted a source water assessment to determine the susceptibility of our source water to contamination. The final assessment will not be completed until late this year, but you can review the preliminary results on the internet at http://maps.cares.missouri.edu/maproom/SwipMaps/index.html.
Why are there contaminants in my
water?
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 the 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 at
1-800-426-4791.
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 storm water 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 storm water 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 storm
water 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 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.
Is our water system meeting
other rules that govern our operations?
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
MO5010142 for the purposes 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 the state requirements or
standards will be further explained later in this report.
How might I become actively
involved?
If you would like to 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 417-237-7300 to
inquire about scheduled meetings or contact persons.
Do I need to take special
precautions?
Some people may be more vulnerable to contaminants
in drinking water than the general population. Immuno-compromised persons such
as persons with cancer that are 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).
Contaminants
Report
Carthage Water and Electric routinely monitors
for contaminants in your drinking water according to Federal and State laws.
This table shows the results of our monitoring for the period of January 1 to December 31, 2006.
All drinking water, including bottled drinking water, may be reasonably
expected to contain at least small amounts of some contaminants. It's important to remember that the presence
of these contaminants does not necessarily pose a health risk.
Definitions and Abbreviations:
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.
AL: Action Level, or the concentration of a contaminant which, when exceeded, triggers treatment or other requirements which a water system must follow.
TT: Treatment Technique, or a required process intended to reduce the level of contaminant in drinking water.
90th Percentile: For lead and copper testing. 10% of rest results are above this level and 90% are below this level.
Level Found: The average of all test results for a particular contaminant.
Range of Detections: Shows the lowest and highest levels found during a testing period, if only one sample was taken, then this number equals the Level Found.
MRLDG: Maximum Residual Disinfectant Level Goat, or the level of a drinking water disinfectant below which there is no known or expected risk to health.
MRDL: Maximum Residual Disinfectant Level, or the highest level of a disinfectant allowed in drinking water.
PPB: Parts per billion or micrograms per liter.
ppm: Parts per million or milligrams per liter.
n/a: Not applicable.
NTU: Nephelometric Turbidity Unit, used to measure cloudiness in drinking water.
MFL: Million fibers per liter, used to measure asbestos concentration.
ND: Not detectable at testing limits.
The State has reduced monitoring requirements for
certain contaminants to less often than once per year because the
concentrations of these contaminants are not expected to vary significantly
from year to year. Records marked with *, though representative, are more than
one year old.

Contaminants Report Continued
Unregulated Contaminants Notice
Our water system participated in the Unregulated Contaminant monitoring
required by the Environmental Protection Agency (EPA). This special monitoring
helps EPA decide if new contaminants of concern are found in drinking water at
levels that need to be controlled. We did not detect any of these unregulated
contaminants in our water. If you want to review the individual results of the
monitoring, please contact us at the phone number listed under “How might I
become actively involved?”
Unregulated Contaminants
Unregulated contaminants are those for which the
EPA has not established drinking water standards. The purpose of unregulated
contaminant monitoring is to assist the EPA in determining the occurance of
unregulated contaminants in drinking water and whether future regulation is warranted.
Information on all the contaminants that were monitored for, whether regulated
or unregulated, can be obtained from this water
System or the Department of Natural Resources.
