Per- and Polyfluoroalkyl Substances

Public Disclosure of Results of Department of Defense (DoD) Testing of Off-Base Drinking Water in a Covered Area for Per- and Polyfluoroalkyl Substances (PFAS)

DoD conducts sampling of drinking water off-base to ensure the Department identifies potential impacts of PFAS resulting from DoD activities. Off-base drinking water includes non-DoD drinking water systems and private wells located outside the installation boundary. In accordance with Section 345 of the National Defense Authorization Act for Fiscal Year 2022, DoD is providing the final testing results for off-base drinking water located in “covered areas.” Covered areas are locations in the United States that are adjacent to and down gradient from a military installation, Formerly Used Defense Site (FUDS), or National Guard facility.

DoD has been actively testing and monitoring off-base drinking water since 2016. DoD’s priority is to quickly address levels of perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) in drinking water found above 70 parts per trillion (ppt). DoD’s actions are consistent with EPA’s recommended actions, which include treatment of drinking water or providing alternative water supplies, such as bottled water, implementing a whole-house filtration system, or connecting residents served by private wells to public drinking water systems.

You can find the information about final testing results for PFAS or planned PFAS testing in off-base drinking water within a covered area by either using the search fields or clicking on the map below. States colored teal on the map include searchable final testing results for PFAS in off-base drinking water. Planned PFAS testing in the current quarter is displayed as part of the summary overview for each installation. States shaded gray do not have final PFAS testing results or planned PFAS testing during the current quarter. When using the search fields you may select up to five different installations from the same State. For a more detailed search, including State, DoD Component, installation, report start date, and report end date, please see the Advanced Search tab at the top of this page.

In an effort to enhance transparency and communicate ongoing efforts associated with PFAS investigations, DoD is providing enhanced functionality to search testing dates or download a testing report, select a State, DoD Component (All Components by default), and up to three different installations from the same State. A selection is required in each field to generate a query and result. Click the “Download Testing Date Report” button(s) to download files and view reports.

The Department of Defense (DoD) conducts sampling of drinking water off-base to ensure it identifies potential impacts of Per- and Polyfluoroalkyl Substances (PFAS) resulting from DoD activities. Final testing results for PFAS in off-base drinking water in a covered area are searchable by State, DoD component, installation, report start date, and report end date. The database includes installations that have currently reported final sample data per Section 345 of the National Defense Authorization Act for Fiscal Year 2022. Results can be further filtered by PFAS analyte(s). To filter by PFAS analyte, click on the dropdown for “Select PFAS Analyte(s)” and select the PFAS analyte(s) for your search. Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) are selected as default analytes.
