2011 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 269-8155.  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 second and fourth Wednesday of every month in the Municipal Building 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 most recent results available for each parameter.  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 (ug/l) - 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.

All sources of drinking water are subject to potential contamination by constituents that are naturally occurring or man made.  Those constituents can be microbes, organic or inorganic chemicals, or radioactive materials.

 

More information about contaminants and potential health effects can be obtained by calling the Environmental Protection Agency's Safe Drinking Water Hotline at 1-800-426-4791.

 

MCL's are set at very stringent levels. To understand the possible health effects described for many regulated constituents, a person would have to drink 2 liters of water every day at the MCL level for a lifetime to have a one-in-a-million chance of having the described health effect.

 

Lead:  Lead in drinking water is rarely the sole cause of lead poisoning, but it can add to a person's total lead exposure. All potential sources of lead in the household should be identified and removed, replaced or reduced.

 

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. EPA/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 (800-426-4791). 

 

Due to a waiver from the state this year we will not be mailing this report, copies of this same report are available at 425 Water St.  Please call our office if you have questions.
