The toxic compounds have been detected in water systems and groundwater throughout the state, including sites in Bloomington, Chicago, Galesburg, Peoria and the Quad Cities area. PFAS has also been detected in the groundwater at Scott Air Force Base, Chanute Air Force Base, Naval Station Great Lakes, and the Rock Island Arsenal.
