2010
We are pleased to provide
you with this year's Annual Water Quality Report also known by the federal
acronym CCR (Consumer Confidence Report). We want to keep you informed about the excellent water and
services we have delivered to you over the past year. Our goal is, and always
has been, to provide to you a safe and dependable supply of drinking water. The
well that serves your area is located on the east side of
If you have any questions about this report or concerning your
water utility, please contact Mike Galante, District Manager at (208)

North Kootenai Water District
monitors for contaminants in your drinking water according to Federal and State
laws. The table below shows any detection of contaminants over the past five
years. We are pleased to notify you that
our water has not exceeded any allowable detection levels. As water travels
over the land or underground it can pick up contaminants such as microbes,
inorganic and organic chemicals, and radioactive substances. 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.
In the following table you will find some terms and abbreviations
that you may not be familiar with. To help you better understand these terms we
provide the following definitions:
Action Level - The
concentration of a contaminant that, if exceeded, triggers treatment or other
requirements that a water system must follow.
Maximum
Contaminant Level (MCL) - The “Maximum Allowed” 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 Goal (MCLG) - The “Goal” is 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.
Non-Detects (ND) - Laboratory analysis indicates that the constituent is not
present.
Parts per
million (ppm) or Milligrams
per liter (mg/l) - 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 - One part per billion
corresponds to one minute in 2,000 years or a single penny in $10,000,000.
Picocuries per liter (pCi/L) - Picocuries
per liter is a measure of the radioactivity in water.
Variances &
Exemptions (V&E) - State or Federal
Environmental Protection Agency (EPA) permission not to meet a MCL or a
treatment technique under certain conditions.

Lead – If present, elevated levels of lead can cause serious health problems,
especially for pregnant women and young children. Lead in drinking water is primarily from
materials and components associated with service lines and home plumbing. North Kootenai Water District is responsible
for providing high quality drinking water, but cannot control the variety of
materials used in plumbing components.
When your water has been
sitting for several hours, you can minimize the potential for lead exposure by
flushing your tap for 30 seconds to 2 minutes before using water for drinking
or cooking. If you are concerned about
lead in your drinking water, you may wish to have your water tested. Information on lead in drinking water,
testing methods and steps you can take to minimize exposure is available from
the Safe Drinking Water Hotline or at http://www.epa.gov/safewater/lead.
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. The Federal Environmental
Protection Agency (EPA) and U.S. Center for Disease Control (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.
Our wells are within the
Rathdrum Prairie Aquifer Wellhead Protection Area. This is a geographical and
geological area where strict regulations to protect ground water (drinking
water) are applied.
North Kootenai Water District works diligently to provide 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.
PLEASE
DON’T DUMP ANYTHING ON THE GROUND THAT YOU WOULD NOT WANT TO DRINK!
