Military PFAS Information and Resources

Military installations started using Aqueous Film Forming Foam (AFFF) in the 1970’s as a firefighting agent to extinguish chemical fires or spills but was also used during crash crew training exercises, hanger system operations and testing, and for other emergency response actions.  The Department of Defense (DoD) also uses materials that can contain per- and polyfluoroalkyl substances (PFAS) in the vapor suppression systems at plating shops.

Through 2001, perfluorooctane sulfonic acid (PFOS) and, in some formulations, perfluorooctanoic acid (PFOA) were used in the manufacture of AFFF.  Manufacturers of AFFF in the United States use other PFAS other than PFOS; however, existing stocks of PFOS-based AFFF remain in use.  By 2015, the primary U.S. manufacturers voluntarily phased out production of PFOS and PFOA.

The DoD updated the Military Specification (MILSPEC) for AFFF, so that new supplies available for emergency firefighting responses, do not contain detectable levels of PFOS or PFOA. AFFF is still used by the DoD only to respond to emergency events and treats each use as a spill to limit environmental effects. AFFF is no longer used for maintenance, testing, or training on DoD installations world-wide. The DoD is assessing substitutes for PFAS in AFFF. The latest environmental research, such as finding a PFAS-free AFFF formulation or treating PFAS-contaminated soil, is being performed by the DoD under the Strategic Environmental Research and Development Program (SERDP) and Environmental Security Technology Certification Program (ESTCP) programs. For more information:

Since 2014 or 2015, DoD has been addressing PFAS with preliminary assessments, site investigations, and corrective actions under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) which will be a multi-year process. In 2019, DoD established a PFAS task force to address PFAS at military installations and surrounding communities. The latest task force update is located at: Department of Defense Per- and Polyfluoroalkyl Substances (PFAS) Task Force Progress Report, March 2020.

comprehensive environmental responses, compensation, and liability act process

On July 14, 2021, the DoD held a public outreach event which detailed the roles and responsibilities, funding process, and actions taken as part of the department’s clean up efforts related to PFAS contamination of local communities. The presentation also detailed the DoD’s future goals related to public health outcomes, such as mitigating the future use of AFFF, monitoring the health of firefighters exposed to PFAS, and expanding PFAS related public outreach.

As of May 2020, California has 62 military facilities with a known or suspected per- and polyfluoroalkyl substances (PFAS) release. Since the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) process is a multi-year process with streamlined steps to identify if there is a problem, what the risks are, and how-to cleanup, facilities will be addressed as funding permits.

The State Water Board’s Division of Drinking Water (DDW) and Division of Water Quality (DWQ) are working closely with the Department of Defense (DoD) on identifying and sampling of appropriate municipal supply drinking water wells and drinking water systems that may be at risk to per- and polyfluoroalkyl substances (PFAS) contamination from historic military operations.

Past Efforts:

To ensure safe drinking water, the DoD is proactively sampling drinking water systems on facilities and sampling private drinking water wells off-base if there was a suspected or known release that potentially migrated from a facility. It is a priority for the DoD to address PFAS to protect those living and working on a facility as well as the surrounding communities that may have been impacted. This is a national and international effort to identify releases, investigate and respond to drinking water contamination, and prevent future contamination of PFAS at military facilities.

Between 2013 and 2015, 63 DoD drinking water systems nationwide were required to be sampled for a suite of chemicals, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) included, as part of the U.S. Environmental Protection Agency’s (EPA) Unregulated Contaminant Monitoring Rule program. Only one system (Wright Patterson Air Force Base, Ohio) detected levels above the EPA's (EPA) Provisional Health Advisory.

In 2016, the military tested for PFOA/PFOS in drinking water systems (samples were collected after treatment or blending) where DoD supplies the drinking water. Samples that tested above the EPA’s PFOA or PFOS lifetime health advisory (LHA) of 70 parts per trillion (ppt), those wells were taken offline and systems were re-tested until results were less than EPA’s PFOA/PFOS LHA.  If unable to isolate the source of the PFAS coming into the system and it tested above the LHA, then the DoD provided alternative drinking water. Facilities that DoD is not the drinking water supplier encouraged those suppliers to test the drinking water system and follow EPA advisory recommendations. As of 2017, DoD has conducted off-base testing at 2,445 public and private drinking water systems nationwide as part of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) process.

Future Efforts:

DDW and DWQ are identifying non-military owned municipal supply wells in proximity to military bases under PFAS investigation for future sampling under Health & Safety Code 116378 likely in late 2020 or early 2021.

For military owned municipal drinking water systems that are on facilities under PFAS investigation, the DoD will be implementing their March 2, 2020, DoD drinking water memo.

As future PFAS information for drinking water wells and systems becomes available, information will be provided on the State Water Board’s PFAS Drinking Water Website:
