2010 WATER QUALITY REPORT
Dear
We are pleased to present to
you the 2010 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.

The
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 homes plumbing.
If you are concerned about elevated lead levels in your homes 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).
Nitrates 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. 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 Agencys 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:
(1) Microbial contaminants, such
as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock
operations, and wildlife.
(2) 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.
(3) Pesticides and herbicides,
which may come from a variety of sources such as agriculture, urban stormwater
runoff, and residential uses.
(4) 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.
(5) 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, 2010 to DECEMBER 31, 2010. The table displays the number of contaminants
that were required to be tested in the last five years. It may contain up to five years worth of
water quality results. If a water system
tests annually, or more frequently, the results from the most recent year are
shown. If testing is done less
frequently the results shown are from the past five years.

Level The concentration of a contaminant that, if exceeded, triggers
treatment or other requirements that a water system must follow. |

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. MCLGs allow for a margin of safety. |

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. |

*Systems exceeding a lead
and/or copper action level must take actions to reduce lead and/or copper in
the drinking water. The lead and copper
values represent the 90th percentile of all compliance samples
collected. If you want information on
the number of sites or the actions taken to reduce these levels please contact
the water department.
