Minnesota-based company 3M is suing the state of Michigan over its regulations of per- and polyfluoroalkyl substances, or the PFAS family of chemicals. Michigan's regulations on PFAS in drinking water were finalized in August 2020, and are among the most stringent in the country.
Exposure to some kinds of PFAS has been linked to increased cholesterol, impaired reproductive and immune systems, impaired growth in children, and heightened risk of kidney and testicular cancers. Currently, there are no federal standards from the Environmental Protection Agency for the PFAS family of chemicals in drinking water.
