2007 WATER QUALITY REPORT
Dear
We are pleased to present to
you this year’s annual water quality report.
It is our constant goal to provide you with a safe and dependable supply
of drinking water and to answer any questions you may have concerning your
water service. We are pleased to report
that our drinking water is safe and meets federal and state requirements.
THIS REPORT WILL NOT BE MAILED TO YOU.
However, this report is available upon request. If you have any questions concerning this
report or your water utility, please contact the Village Hall or attend any
Public Works Committee meeting. The
Public Works Committee holds meetings at 6:30 PM on the first Thursday of each
month and the Village Board meets at 7:00 PM on the second Thursday of each
month. The meetings are held at the
Holmen Village Hall and the public is welcomed at all meetings.

To maintain a clean water
system water mains are flushed through the fire hydrants twice a year. The
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 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 microbiological
contaminants are available from the Safe Drinking Water Hotline
(1-800-426-4791).
Infants and young children are
typically more vulnerable to lead in drinking water than the general
population. It is possible that lead
levels at your home may be higher than at other homes in the community as a
result of materials used in your home’s plumbing. If you are concerned about elevated lead
levels in your home’s water you may wish to have your water tested and flush
your tap for 30 seconds to 2 minutes before using tap water. Additional information is available from the
Safe Drinking Water Hotline (1-800-426-4791).
Nitrate in drinking water at
levels above 10-ppm is a health risk for infants of less than 6-months of
age. High nitrate levels in drinking
water can cause blue baby syndrome.
Nitrate levels may rise quickly for short periods of time because of
rainfall or agricultural activity. If
you are caring for an infant you should ask advice from your health care
provider.
“All sources of
drinking water are subject to potential contamination by constituents that are
naturally occurring or man made. Those
constituents can be microbes, organic or inorganic chemicals, or radioactive
materials.” All 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 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 (1-800-426-4791).
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.
Contaminants that
may be present in source water include:
-Microbial contaminants, such as
viruses and bacteria, which may come from sewage treatment plants, septic
systems, agricultural livestock
operations, and wildlife.
-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.
-Pesticides and herbicides,
which may come from a variety of sources such as agriculture, urban stormwater runoff, and residential
uses.
-Organic chemical contaminants,
including synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum
production, and can, come from gas stations, urban stormwater
runoff, and septic systems.
-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 EPA prescribes regulations that limit the
amount of certain contaminants in water provided by public water systems. FDA regulations establish limits for
contaminants in bottled water, which shall provide the same protection for
public health.
The following table shows the
results of our monitoring for the period of JANUARY 1, 2007 to DECEMBER 31, 2007. The table displays the number of contaminants
that were required to be tested in the last five years. This report may contain up to five years worth
of water quality results. The most
recent results are shown.

Term |
Definition |
|
|
Action
Level – The concentration of a contaminant that, if exceeded, triggers
treatment or other requirements that a water system must follow. |
|
MCL |
Maximum
Contaminant Level – The highest level of a contaminant that is allowed in
drinking water. |
|
MCLG |
Maximum
Contaminant Level Goal -- 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. |
|
ppm |
Parts
per million or milligram per liter (mg/l) – Corresponds to one minute in two
years. |
|
ppb |
Parts
per billion or micrograms per liter (ug/l) – Corresponds to one minute in
2,000 years. |
|
pCi/L |
Picocuries
per liter (a measure of radioactivity) – A measure of the radioactivity in
water. |
|
ND |
Non-detects
– A lab analysis indicates that the constituent is not present. |
|
TCR |
Total
Coliform Rule establishes regulations for microbiological contaminants in
drinking water. This rule requires
water systems to meet a stricter limit for coliform bacteria. 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. |
