Annual Drinking Water Quality Report
VILLAGE OF LOMIRA
We're very pleased to provide you with this year's Annual
Drinking Water Quality 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. Our water source is ground water, our wells draw from Sandstone Aquifer.
This report shows our water quality and what it means. A
copy of this report is available upon request.
If you have any questions about this report or concerning
your water utility, please contact Brian Koll, Director of Public Works at
269-4112. We want our valued customers to be informed about their water
utility. If you want to learn more, please attend any of our regularly scheduled
meetings. They are held on the first and third Wednesday of every month at 7:30
P.M.
Village of Lomira routinely monitors for constituents in
your drinking water according to Federal and State laws. This table shows the
results of our monitoring for the period of January 1st to December 31st, 2007.
All drinking water, including bottled drinking water, may be reasonably expected
to contain at least small amounts of some constituents. It's important to
remember that the presence of these constituents does not necessarily pose a
health risk.
In this table you will find many terms and abbreviations
you might not be familiar with. To help you better understand these terms we've
provided the following definitions:
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.
Parts per trillion (ppt) or Nanograms per liter
(nanograms/l) - one part per trillion corresponds to one minute in 2,000,000
years, or a single penny in $10,000,000,000.
Parts per quadrillion (ppq) or Picograms per liter (picograms/l)
- one part per quadrillion corresponds to one minute in 2,000,000,000 years
or one penny in $10,000,000,000,000.
Picocuries per liter (pCi/L) - picocuries per liter
is a measure of the radioactivity in water.
Millirems per year (mrem/yr) - measure of radiation
absorbed by the body.
Million Fibers per Liter (MFL) - million fibers per
liter is a measure of the presence of asbestos fibers that are longer than 10
micrometers.
Nephelometric Turbidity Unit (NTU) - nephelometric
turbidity unit is a measure of the clarity of water. Turbidity in excess of 5
NTU is just noticeable to the average person.
Action Level - the concentration of a contaminant
which, if exceeded, triggers treatment or other requirements which a water
system must follow.
Treatment Technique (TT) - A treatment technique is
a required process intended to reduce the level of a contaminant in drinking
water.
Maximum Contaminant Level - The "Maximum Allowed" (MCL)
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 - The "Goal" (MCLG)
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.

state allows us to monitor for some contaminants less than once per year
because the concentrations of these contaminants do not change
frequently. Some of our data, though representative, are more than one
