AFFF Firefighting Foam
OpenFASTCausation
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.

Defense counsel at NYU MDL conference: ~20,000 PI cases sat on the MDL 2873 docket ~5 years with fact sheets but no vetting. When defendants raised PI settlement (late 2024/early 2025), leadership disclosed ~100,000 claims; after Judge Gergel's vetting order the docket reached ~130,000 within ~3 months. Tens of thousands since dismissed or failed proof; ~100,000 remain. Federal officer removal has kept most cases out of state court.
