Where to File in Idaho

Idaho personal injury claims are governed by Idaho Code § 5-219(4), providing a 2-year limitations period. Federal PFAS claims proceed in MDL 2873 (D.S.C.). Mountain Home AFB in Elmore County is the primary military PFAS contamination site in Idaho. The city of Mountain Home relies on groundwater sources that have been tested for PFAS contamination from AFFF operations. Idaho's extensive agricultural use of biosolids creates additional PFAS exposure concerns in rural communities.
