Opportunity for input on decisions affecting your water quality

Third Tuesday of the month – 2:30 p.m. at the Water and Light Office, 507 19th St, Brodhead WI.

Health Information
Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the Environmental Protection Agency's safe drinking water hotline (800-426-4791).

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 systems 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 microbial contaminants are available from the Environmental Protection Agency's safe drinking water hotline (800-426-4791).

Educational Information
The sources of drinking water, both tap water and bottled water, include rivers, lakes, streams, ponds, reservoirs, springs and wells. As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from human activity.

Contaminants that may be present in source water include:
  • Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations and wildlife.
  • Inorganic contaminants, such as salts and metals, which can be naturally- occurring or result from urban stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining or farming.
  • Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban stormwater runoff and residential uses.
  • Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum production, and can also come from gas stations, urban stormwater runoff and septic systems.
  • Radioactive contaminants, which can be naturally occurring or be the result of oil and gas production and mining activities.
In order to ensure that tap water is safe to drink, EPA prescribes regulations that limit the amount of certain contaminants in water provided by public water systems. FDA regulations establish limits for contaminants in bottled water, which shall provide the same protection for public health.

Definitions 
term                     definition
AL  Action Level: The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow. 
Level 1 Assessment A Level 1  assessment is a study of the water system to identify potential problems and determine, if possible, why total coliform bacteria have been found in our water system. 
Level 2 Assessment  A Level 2 assessment is a very detailed study of the water system to identify potential problems and determine, if possible, why an E. coli MCL violation has occurred or why total coliform bacteria have been found in our water system, or both, on multiple occasions. 
MCL  Maximum Contaminant Level: 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. 
MCLG  Maximum Contaminant Level Goal: 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.
MFL  million fibers per liter 
MRDL  Maximum residual disinfectant level: The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for microbial contaminants. 
MRDLG  Maximum residual disenfectant level goal: The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contaminants. 
mrem/year  millirems per year (a measure of radiation absorbed by the body) 
NTU  Nephelometric Turbidity Units 
pCi/l  picocuries per liter (a measure of radioactivity) 
ppm  parts per million, or milligrams per liter (mg/l) 
ppb  parts per billion, or micrograms per liter (ug/l) 
ppt  parts per trillion, or nanograms per liter 
ppq  parts per quadrillion, or picograms per liter 
TCR  Total Coliform Rule 
TT  Treatment Technique: A required process intended to reduce the level of a contaminant in drinking water 

Detected Contaminants
Your water was tested for many contaminants last year. We are allowed to monitor for some contaminants less frequently than once a year. The following tables list only those contaminants which were detected in your water. If a contaminant was detected last year, it will appear in the following tables without a sample date. If the contaminant was not monitored last year, but was detected within the last 5 years, it will appear in the tables below along with the sample date.

Unregulated Contaminants
Unregulated contaminants are those for which EPA has not established drinking water standards. The purpose of unregulated contaminant monitoring is to assist EPA in determining the occurrence of unregulated contaminants in drinking water and whether future regulation is warranted. EPA required us to participate in this monitoring.

Additional Health Information
If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. Brodhead Waterworks is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline or at www.epa.gov/safewater/lead.

Important Information about the Fluoride level
We are required to notify you when we discover that the fluoride levels in your drinking water exceed 2 mg/l because of the cosmetic dental problem described below. The drinking water provided by your community water system, Brodhead Waterworks (Water and Light), had a fluoride concentration of 3.99 mg/l as reported on one occasion in 2017 in a sample tested by a company that had not previously been used by Brodhead Water and Light. Because this report was significantly INCONSISTENT with typical daily results, which range from 0.6 to 0.8 mg/l, an immediate resampling was conducted and yielded normal results. Brodhead Water and Light is confident that no customer’s tap water carried fluoride levels outside of the normal range.

As a result of the test, that was inconsistent with our normal testing. We are required to inform the public of the possible effects of high levels of fluoride in the water. At low levels, fluoride can help prevent cavities, but children drinking water containing more than 2 milligrams per liter (mg/l) of fluoride may develop cosmetic discoloration of their permanent teeth known as dental fluorosis. Dental fluorosis, in its moderate or severe forms, may result in a brown staining and /or pitting of permanent teeth. This problem occurs only in developing teeth, before they erupt from the gums. Children under 9 should be provided with alternative sources of drinking water or that has been treated to remove the fluoride to remove the possibility of staining and pitting of their permanent teeth. You may also want to contact your dentist about proper use by young children of fluoride-containing products. Older children and adults may safely drink the water. Some home water treatment units are also available to remove fluoride from drinking water. To learn more about available home water treatment units, you may call NSF International at 1-877-8-NSF-HELP. For more information, please call Patrick Sullivan of Brodhead Water and Light at (608) 897-2505.
