The Michigan Department of Environment, Great Lakes, and Energy (EGLE) today announced that Michigan's new standards limiting per- and polyfluoroalkyl substances (PFAS) in public drinking water supplies are being met by most of the state's roughly 2,700 municipal and other large public drinking water systems less than a year after the standards were adopted.
EGLE is posting data for drinking water systems still working toward compliance on the new Compliance Monitoring webpage.
Per- and polyfluoroalkyl substances (PFAS) are a large group of man-made chemicals that include perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS). PFAS have been used globally during the past century in manufacturing, firefighting and thousands of common household and other consumer products. These chemicals are persistent in the environment and in the human body – meaning they don’t break down and they can accumulate over time. In recent years, experts have become increasingly concerned by the potential effects of high concentrations of PFAS on human health.
