National Drinking Water Database
Bad Axe - Pigeon, MI
Serves 3,574 people - Test data available: 2007
This drinking water quality report shows results of tests conducted by the water utility and provided to the Environmental Working Group (EWG) by the Michigan Department of Environmental Quality. It is part of EWG's national database that includes 47,667 drinking water utilities and 20 million test results. Water utilities nationwide detected more than 300 pollutants between 2004 and 2009. More than half of these chemicals are unregulated, legal in any amount. Despite this widespread contamination, the federal government invests few resources to protecting rivers, reservoirs, and groundwater from pollution in the first place. The information below summarizes test results for this utility and lists potential health concerns.
Contaminants Exceeding Health Guidelines
Other Detected Contaminants
Testing History-Tested      -Detected      -Over Health Guidelines      -Over Legal Limit*
|Bromochloroacetic acidBromochloroacetic acid is a disinfection byproduct, and is formed when chlorine, chloramines or other disinfectants react with organic and inorganic matter in water.||6.63 ppb|
|No||Legal at any levelThis is the Federal Limit. State Limits may be lower.|
|Dibromoacetic acidDibromoacetic acid is a disinfection byproduct regulated by EPA as one of five haloacetic acids that are formed when chlorine, chloramines or other disinfectants react with organic and inorganic matter in water.||0.25 ppb|
|NOTE: Each dot in the above graph represents one month.|
* Water utilities are noted as exceeding the legal limit if any test is above the maximum contaminant level (MCL). Most MCLs are based on annual averages so exceeding the MCL for one test does not necessarily indicate that the system is out of compliance.

EPA Violation Summary
No violations were reported for this system since 2004.
Information on violations is drawn directly from EPA's national violations database in the Agency's Safe Drinking Water Information System. Analyses by others have raised questions about the quality of the information in EPA's database. For the purposes of this investigation, EWG is not showing below or including in our analyses, those violations for individual water suppliers that occurred on days for which the total number of violations assigned by EPA to that water supplier was greater than 20. This criteria was based on common characteristics of incorrect violations data as identified by water utilities, from a review of EPA's violations data by several hundred utilities prior to the release of EWG's investigation.
