2005
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 wells that serve your area are located on
Your
drinking water is safe and meets federal and state requirements.
If you have any questions about this report or concerning
your water utility, please contact Mike Galante, District Manager at (208)
772-3619. If you want to learn more,
please attend any of our regularly scheduled Board meetings that are held at
12:30 PM on the first and third Thursday of each month at the District office:
North
Kootenai Water District monitors for
contaminants in your drinking water according to Federal and State laws. The
table below shows the results of our monitoring for the period of January 1 to
December 31, 2005. 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've provided 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
EPA permission not to meet a MCL or a treatment technique under certain
conditions.
