Perfluoroalkyl and polyfluoroalkyl substances (PFAS), such as perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), are part of a group of chemicals used globally during the past century in manufacturing, firefighting and thousands of common household and other consumer products.
In recent years, experts have become increasingly concerned by the potential effects of high concentrations of PFAS on human health. Learn more about PFAS at www.michigan.gov/pfasresponse.
Drinking Water Testing
The State of Michigan is working proactively to identify locations where PFAS may be present as a contaminant. The Michigan Department of Environmental Quality is testing all of the public systems in Michigan this year, and many already have been tested.
