Water Quality
Report
Hanalei
Results:
The
following tables lists all the drinking water contaminants that were
found in 2000. Unless
otherwise noted,
the data
presented in the following tables are from testing done January 1 -
December 31, 2000.
The
State requires us to monitor for certain contaminants less than once per
year because the concentrations of these contaminants are not expected
to vary from year to year. Thus, some of the data, though representative
of the water quality, is more than one year old.
Terms and abbreviations used below:
Maximum
Contaminant Level Goal (MCLG)
: is the level of contaminant in drinking water below which
there is no known or expected risk
to health. MCLGs
allow for a
margin of safety.
Maximum Contaminant Level (MCL):
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.
Action
Level (AL): the concentration of a contaminant which, when
exceeded, triggers treatment or other requirements which a water system must follow.
n/a:
not
applicable, nd: not detectable at
testing limit, ppm: parts per million or milligrams per liter (corresponds to
one penny in $10,000), ppb: parts per billion or micrograms per liter (corresponds to one penny
in $10,000,000), pCi/l:
picocuries per liter(a
measure of radiation), mrem/year:
millirems per year (a
measure of radiation exposure).
What is the pH of my Water?
The pH of
your water in the Hanalei area can range from 7.8.
What is the hardness of my water?
The hardness of your water is approximately 100 ppm.

The
Hanalei system is in compliance with Lead and Copper Rule requirements
and is on a reduced monitoring schedule.
Samples for lead and copper will be taken and analyzed ever three
years.
