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.
This report includes the sample date, laboratory sample identifier, analysis method, and Per- and Polyfluoroalkyl Substances (PFAS) testing results for each drinking water sample. The report indicates whether the testing results for PFAS are above or below the detection limits. Detection limits represent the lowest concentration of a chemical that can be accurately measured by the laboratory equipment. The data distinguishes if the sample was taken pre-treatment (i.e., “raw groundwater” before an installed filtration system was used to reduce levels of PFAS below the Environmental Protection Agency’s (EPA) 2016 Health Advisory (HA) in drinking water) or post-treatment (i.e., “finished drinking water” after the filtration system was used and where water is actually being consumed).
For information regarding PFAS Chemical Abstract Services (CAS) Registry Numbers, analyte names, and analyte abbreviations, click here. DoD uses validated EPA methods 533, 537, 537.1, and 1633 and DoD Quality Systems Manual Table B-15 to test for PFAS in drinking water. For more information about the validated EPA methods, see EPA.gov. For additional information on DoD Quality Systems Manual Table B-15 analysis method, please see the Environmental Data Quality Workgroup website.
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.
Component
The sampling results per Section 345 of the National Defense Authorization Act for Fiscal Year 2022 are only reported for locations outside of the installation boundary. (The Department of Defense (DoD) separately manages and reports on-base drinking water where DoD operates the drinking water system.) The sampling results provided on this webpage include both drinking water consumed and water that is being treated before being consumed. DoD quickly treats water or provides an alternative drinking water source when tests indicate perfluorooctane sulfonate (PFOS) or perfluorooctanoic acid (PFOA) above 70 parts per trillion (ppt). (Sampling results that display above 70 ppt for PFOS or PFOA are indicative of water not being consumed.) DoD continues to sample, investigate, and identify off-base locations where there is known or potential risk of a PFAS release. DoD will conduct long-term cleanup action as necessary.
The final reported data includes the sample date, laboratory sample identifier, analysis method, and testing results for PFOS and PFOA in each drinking water sample. Additional PFAS data associated with samples obtained from a treatment system are available through the advanced search option. Quarterly Scheduled Test Dates are highlighted green if PFAS testing is planned in off-base drinking water during the current quarter.

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.
The Department of Defense (DoD) conducts sampling of drinking water off-base to identify potential impacts of Per- and Polyfluoroalkyl Substances (PFAS) resulting from DoD activities. The Report Data Archive contains reports of final testing results for installations that have reported data per Section 345 of the National Defense Authorization Act for Fiscal Year 2022. Final testing results reports are searchable and available for PDF download in the Report Data Archive. Use the keyword search below to locate the archived PDF report you are searching for.
