PFAS (per- and polyfluoroalkyl substances) in AFFF firefighting foam are linked to kidney cancer, testicular cancer, thyroid disease, and liver damage. Firefighters and military personnel with occupational exposure face highest risk. EPA has set near-zero MCLs for PFOA and PFOS in drinking water. 3M internal documents show knowledge of PFAS toxicity dating to the 1970s.
