Bronson Water Report

 

Water Quality For the City of Bronson:

This report covers the drinking water quality for the City of Bronson for the 2007 calendar year.  This information is a snapshot of the quality of the water that we provided to you in 2007.  Included are details about where your water comes from, what it contains, and how it compares to Environmental Protection Agency (EPA) and state standards.

 Your water comes from two groundwater wells east of town on South Parham Road.  The State performed an assessment of our source water to determine the susceptibility or the relative potential of contamination.  The susceptibility rating is on a seven-tiered scale from "very-low" to "very-high" based on geologic sensitivity, well construction, water chemistry and contamination sources.  The susceptibility of our source is rated as “very high” for both wells.  Copies of this report is available at the city office at 141 S. Matteson.

 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 EPA’s Safe Drinking Water Hotline (800-426-4791).

 Vulnerability of sub-populations:  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 Safe Drinking Water Hotline (800-426-4791).

  Sources of drinking water:  The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells.  Our water comes from 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:

 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. Food and Drug Administration regulations establish limits for contaminants in bottled water which provide the same protection for public health.


 

Bronson Water Quality Data:

The table below lists all the drinking water contaminants that we detected during the 2007 calendar year.  The presence of these contaminants in the water does not necessarily indicate that the water poses a health risk.  Unless otherwise noted, the data presented in this table is from testing done January 1 – December 31, 2007.  The State allows us to monitor for certain contaminants less than once per year because the concentrations of these contaminants are not expected to vary significantly from year to year.  All of the data is representative of the water quality, but some are more than one year old.

 Terms and abbreviations used below:

·         Maximum Contaminant Level Goal (MCLG):  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.

·         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.

·         Maximum Residual Disinfectant Level (MRDL):  means the highest level of a disinfectant allowed in drinking water.  There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.

·         Maximum Residual Disinfectant Level Goal (MRDLG):  means 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.

·         N/A:  Not applicable   ND:  not detectable at testing limit  ppb:  parts per billion or micrograms per liter  ppm:  parts per million or milligrams per liter  pCi/l:  picocuries per liter (a measure of radioactivity).

·         Action Level:  The concentration of a contaminant which, if exceeded, triggers treatment or other requirements that a water system must follow.

*      These arsenic values are effective January 23, 2007

***   Unregulated contaminants are those for which EPA has not established drinking water standards. Monitoring helps EPA to determine where certain contaminants occur and whether it needs to regulate those contaminants.

 

Monitoring and Reporting Requirements: The State and EPA require us to test our water on a regular basis to ensure its safety.  We met all the monitoring and reporting requirements for 2007.  We will update this report annually and will keep you informed of any problems that may occur throughout the year, as they happen. Copies are available at the city office, 141 South Matteson. This report will not be sent to you.

 We invite public participation in decisions that affect drinking water quality. These are held the second Monday of each month at 5 pm at 141 South Matteson St . For more information about your water, or the contents of this report, contact Mr. Chuck Buckley at (369-5745).
