2006 Water Quality Report
Is my drinking water safe?
Yes,
our treated water meets all of EPA’s
health standards. We have conducted numerous tests for over 80 contaminants
that could be in drinking water. As you’ll
see in the chart on the back, we detected only 11 of these contaminants. We found all
of these contaminants to be at safe levels.
What is the source of my water?
Your
water comes from the Elk
River on Tim's Ford Lake located on State Highway 130, about 3 miles from
Winchester. Our goal is to protect our water from contaminants and we
are working with the State of
An
explanation of
Drinking
water, including bottled water, may reasonably be expected to contain at least
small amounts of some contaminants.
Community water systems are required to disclose the detection of
contaminants; however, bottled water companies are not required to comply with
this same regulation. 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 at (800) 426-4791.

The Board of Public
Utilities meets on the second
Monday of each month at the Winchester Utilities main office building at 219
2nd Avenue N.W. in
Is our water system meeting other rules that
govern our operations?
The
State and EPA require us to test and report on our water on a regular basis to
ensure its safety. We have met all of these requirements. We want you to know that we pay attention to
all the rules.
Due
to all water containing dissolved contaminants, occasionally your water may
exhibit slight discoloration.
We strive to maintain the standards to prevent this. We at the Winchester
Water System work around the clock to provide top quality water
to every tap. We ask that all our customers help us
protect our water sources, which are the heart of our community, our way of
life, and our children’s future.
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
under-gone 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 not only their drinking
water, but food preparation, personal hygiene, and precautions in handling
infants and pets from their health care providers. EPA/CDC guidelines on appropriate means to
lessen the risk of infection by Cryptosporidium
and other microbiological contaminants are available from the Safe Drinking
Water Hotline at (800) 426-4791.

What does this
chart mean?
·
Maximum Contaminant Levels (MCL): are set at very stringent levels. 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.
·
Maximum Contaminant Level Goal (MCLG): The level of a contaminant in drinking water below
which there is no known or expected risk to health. MCLG’s
allow for a safe margin of safety.
·
Maximum Residual Disinfectant Level Goal (MRDLG): The level of a drinking water
disinfectant below which there is no known or expected risk to health. MRDLG’s do not reflect the benefits of the use of
disinfectants to control microbial contaminants.
·
Parts per million (ppm) or Milligrams per
liter: Explained as
a relation to time and money as one part per million corresponds to one minute
in two years or a single penny in $10,000.
·
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.
·
Action Level (
·
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.
·
Non-Detects
(ND): Laboratory analysis
indicates that the contaminant is not present.
Unless otherwise noted, the data presented in this table is from sampling performed during the 2006 calendar year.

Important Information about Your
Drinking Water Monitoring
Requirements not met for Winchester
Utilities
Our water system recently violated a
drinking water standard. Although this was not an emergency, as our customers,
you have a right to know what happened, what you should do, and what we did to
correct this situation.
We are required to monitor your
drinking water for specific contaminants on a regular basis. Results of regular
monitoring are an indicator of whether or not our drinking water meets health
standards. During the period of November 2005, December 2005 and February 2007,
we did not complete all monitoring requirements for Individual Filter Turbidity
and therefore cannot be sure of the quality of our drinking water during that
time.
What should I do?
You do not need to boil your water or take other actions. We do not know of any
contamination, and none of our testing during the months listed showed any
disease-causing organisms in the drinking water.
What does this mean?
Turbidity has no health effects.
However, turbidity can interfere with disinfection and provide a medium for
microbial growth. Turbidity may indicate the presence of disease causing
organisms. These organisms include bacteria, viruses, and parasites, which can
cause symptoms such as nausea, cramps, diarrhea, and associated headaches. These
symptoms are not caused only by organisms in drinking water. If you experience
any of these symptoms and they persist, you may want to seek medical advice.
What happened? What is being done?
We are required to monitor and
record turbidity from each filter every 15 minutes that the plant is in
operation. During some days in November 2005, December 2005 and February 2007
one of our individual filter turbidity recorders was not fully operational and
the required data was not recorded. We were taking readings on the water being
pumped to the customers every two hours.
Steps We Are Taking
The Winchester Utilities Water
System has purchased a computer to collect the required data from each filter along
with having our personnel at the treatment plant keeping an hourly check to
insure the recorders are operational.
For more information, please contact
Howard Walls of the Winchester Utilities Water System at (931) 967-1732 or
Please share this information with
all the other people who drink this water, especially those who may not have
received this directly (for example, people in apartments, nursing homes,
schools, and businesses). You can do this by posting this notice in a public
place or distributing copies by hand or mail.
