PFAS Data

On-Base DRINKING Water Information

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, DoD has tested all DoD-owned and operated drinking water systems for PFAS. DoD has taken action at locations where on-base drinking water exceeded 70 parts per trillion (ppt) of PFOS and PFOA.

On April 26, 2024, the EPA published a final federal National Primary Drinking Water Regulation (NPDWR) establishing drinking water standards for certain PFAS under the Safe Drinking Water Act (SDWA). This rule applies to public drinking water systems. EPA’s drinking water rule includes enforceable Maximum Contaminant Levels (MCL) for five PFAS. It also includes a Hazard Index (HI) MCL for mixtures of certain PFAS. The rule provides five years for regulated public water systems to comply. The Department is collecting the necessary sampling information and is taking actions to ensure compliance within the required 5-year timeframe.

On-Base Drinking Water Testing Results

DoD is providing the testing results for PFAS in drinking water collected from DoD-owned drinking water systems in the table below. The testing results can be sorted by State, DoD Component, Installation, Drinking Water System, and Analyte. To filter the data, click on the dropdown and select the search term.

Information to consider when conducting searches includes:

  • DoD Component filter: National Guard and Reserve installations are included as part of the “Air Force” or “Army.” U.S. Marine Corps installations are included as part of the “Navy.”
  • To select multiple data elements within a filter, hold down Ctrl+ and click on the element to add.
  • If a search term returns no results, the data for that search term is currently not available.
  • Default analytes displayed are Perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA), Hexafluoropropylene oxide-dimer acid (HFPO-DA), Perfluorobutanesulfonic acid (PFBS), Perfluorohexanesulfonic acid (PFHxS), and Perfluorononanoic acid (PFNA).
