Toxic ‘forever chemicals’ were used to fight Rockton factory fire, causing concern from EPA

The Illinois EPA said the foam initially used was a “flourinated surfactant” that could contain PFOA, or perfluorooctanoic acid, and PFHxA, or perfluorohexanoic acid. Both are among some 5,000 PFAS compounds with oil- and water-resistant properties used in clothing, furniture, cookware, food packaging, cosmetics and other goods.
