This bill requires the Department of Defense (DOD) to attain specific standards in cleaning up perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) contamination in drinking water and other groundwater from past DOD and National Guard activities. Specifically, DOD must reduce the presence of PFOS and PFOA in drinking water and other groundwater to meet or exceed the most stringent standard among federal health advisories and enforceable federal and state requirements.
