Illinois will take a first step toward reducing the use of firefighting foam containing harmful “forever chemicals” under a bill signed into law by Gov. J.B. Pritzker Friday.
The measure aims to curb the use of one source of PFAS chemicals that are tied to a host of health threats, largely through a limitation on using the foam for anything other than emergencies. Fire departments that want to conduct emergency drills or test the foam have to take precautions that prevent the chemicals from reaching waterways through sewer systems, for instance.
The bill, a compromise between environmental groups, an association of fire chiefs and industry groups, does not restrict any use in an emergency. The foam is used for serious industrial fires like those that can occur at a refinery, chemical plant or another source of flammable liquids.
