"TRAVERSE CITY, Mich. — More than 60 drinking water systems in Michigan sampled last year had measurable levels of a class of long-lasting and highly toxic chemicals linked to cancer and a variety of other illnesses, state officials said Monday.
The Department of Environmental Quality released data from a statewide effort to determine the extent of drinking water contamination from perfluoroalkyl and polyfluoroalkyl substances, known collectively as PFAS, which increasingly have turned up in public water supplies and private wells around the U.S. They are used in firefighting foam, nonstick pots and pans, water-repellent clothing and many other household and personal items.
The Michigan agency said it oversaw sampling of 1,114 public water systems and 17 operated by tribes. Also tested were supplies at 461 schools and 168 child care and Head Start providers that operate their own wells."
