Section 345 Data Reporting
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 it 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", which are areas 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. More importantly, DoD has been responding to and taking action to address levels of perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) in drinking water found above EPA’s 2016 final Health Advisory (HA) levels.
DoD’s priority is to quickly address PFOS and/or PFOA in drinking water above the U.S. Environmental Protection Agency (EPA) 2016 final lifetime drinking water health advisories (HAs) from DoD activities. 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.
What is included in Section 345 Reporting?
The drinking water sampling results in the Section 345 Reporting are only for locations outside of the installation boundary; DoD separately manages and reports on-base drinking water where DoD is the purveyor under the Safe Drinking Water Act. The sampling results provided on this webpage include both drinking water currently being consumed and drinking water that isn’t being consumed. In order to quickly make this information publicly available, the data does not distinguish if the sample was taken pre-treatment (i.e., “raw groundwater” before the installed filtration system used to reduce levels of PFAS below the HA in drinking water) or post-treatment (i.e., “finished drinking water” after the filtration system – where water is actually being consumed). However, DoD is collecting this information and will be including it in future public reporting.
DoD continues to perform sampling at impacted locations off-base to further investigate and identify any location where there is known or potential risk of PFAS release.
How to Read the Final Testing Results
Final testing results for PFAS detected in off-base drinking water located within covered areas are searchable by state and are posted by installation. An installation’s PFAS reporting table includes the laboratory sample identifier, sample date, analysis method, and PFAS testing results for each drinking water sample. The table 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.

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.
