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 draw water from the Rathdrum
Prairie Aquifer.
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 second
Thursday of each month at the District office: 1841 W. Hayden Avenue, Hayden,
Idaho.
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 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.
MV1 – Mountain View
Terrace well #1 located on the south side of Elk Street.
MV2 – Mountain View
Terrace well #2 located on the north side of Echo Street.
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.
