Michigan collects 30k gallons of toxic PFAS firefighting foam
News
17 Jun 2020 | MLive
Foam is solidified into a cement-like state before disposal. It was originally headed for U.S. Ecology’s hazardous waste landfill in Belleville, but it has been re-routed to Idaho because the region receives less rainfall and landfills there do not generate as much leachate.
