Massachusetts personal injury claims are governed by M.G.L. ch. 260 § 2A, providing a 3-year limitations period from discovery. Federal PFAS claims proceed in MDL 2873 (D.S.C.). Otis ANGB (Sandwich, MA) on Cape Cod has documented PFAS contamination affecting Cape Cod drinking water — one of the earliest and most studied military PFAS contamination sites in the nation. Hanscom AFB in Bedford has PFAS contamination in the MetroWest/Route 128 corridor. Massachusetts set a statewide PFAS drinking water standard of 20 ppt (the sum of six PFAS) in 2020 — among the nation's most stringent.
