PFAS Data

On-Base Water Data (Military Installations)

On-Base DoD-Owned and Operated Drinking Water Systems

DoD provides drinking water to approximately 2 million people on its installations worldwide. To protect the health of our Service members, their families, and the DoD civilian workforce, the Department tested its DoD-owned and operated drinking water systems and took immediate action to reduce levels of PFOS and PFOA at all locations that tested above 70 parts per trillion (ppt). DoD follows the Environmental Protection Agency’s recommended actions which include treatment of drinking water, closing drinking water wells, providing alternative water supplies such as bottled water, and connecting residents to alternate drinking water systems. In cases where DoD purchases drinking water at installations and finds PFOS and PFOA above 70ppt, DoD encourages drinking water supplier(s) to take corrective action to reduce levels of PFAS.

DoD is ensuring a consistent approach to continued testing of on-base drinking water across DoD so that no one on-base is exposed to PFOS or PFOA above 70ppt in drinking water. The Department first issued policy in March 2020, and updated it July 11, 2023, for continued periodic testing of DoD-operated drinking water systems for certain PFAS, including PFOS and PFOA. The Military Departments will resample water systems periodically based on these results. For consistency across the nation, the Department also issued a policy for monitoring drinking water at installations where DoD purchases drinking water in July 2020.
