PFAS Contamination in Oklahoma

Oklahoma's PFAS contamination is concentrated around military installations and energy industry facilities across the state. Tinker Air Force Base in Oklahoma City has documented extensive soil and groundwater contamination from firefighting foam use, affecting the Canadian River watershed and threatening Oklahoma City's water supply system. Vance Air Force Base has additional contamination affecting northwestern Oklahoma communities and agricultural areas.

Oklahoma's oil and gas industry has potential PFAS sources from drilling operations, refineries, and chemical processing facilities. The state's extensive agricultural economy faces contamination risks from industrial sources and potential impacts on livestock operations and irrigation systems. The Canadian and Arkansas River systems, which provide water to much of the state, require protection from expanding contamination sources.
