Report from EWG shows that Chemical Manufacturers Knew of the Risks Associated with PFAS more than 60 years ago

As the nation’s PFAS contamination problem continues to grow, a report recently released by the Environmental Working Group states that PFAS manufacturers have known about the risks associated with these chemicals for more than 60 years. The report documents studies and internal memos with a timeline that begins in 1950. PFAS manufacturers 3M and DuPont are the focus of the report.
