On July 10, 2018 Michigan’s MLive Media Group reported that a U.S. Coast Guard maintenance hangar at the Selfridge Air National Guard Base near Mount Clemons, Michigan experienced an “inadvertent discharge of about 20 gallons of AFFF foam” on June 7. AFFF is aqueous film-forming foam that contains toxic chemicals containing a variety of per- and poly fluoroalkyl substances, or PFAS. They are used in fire-fighting foams.
