STATEMENT: PFAS testing for drinking water system

March 13, 2023                                                                                

The Michigan Department of Environment, Great Lakes and Energy’s (EGLE) Per and Polyfluoroalkyl compounds (PFAS) drinking water rule requires testing for seven PFAS compounds and established maximum contaminant levels (MCLs). PFAS are man-made compounds used in the manufacturing of carpets, clothing, fabrics for furniture, paper packages for food and other materials that are resistant to water, grease or stains. They are also found in products such as firefighting foams, cleaners, cosmetics, paints, adhesives and insecticides.

The Great Lakes Water Authority (GLWA) has been monitoring PFAS in since 2009. In our latest round of drinking water system testing required under the rule, GLWA is pleased to assure the public that these chemicals were not detected. This means that PFAS levels were below that which is measurable under the EPA’s standard analytical methodology for the detection of the compounds. View the full test results from GLWA’s five water treatment plants here. The water that GLWA distributes to its member partner communities remains water of unquestionable quality.
