Contamination of soils and waters by per- and polyfluoroalkyl substances (PFAS) is a challenge for the Department of Defense (DoD) due to the use of Aqueous Film Forming Foam (AFFF) formulations for fire suppression since the 1970s. Currently, there are no EPA published procedures for PFAS analyses in media other than drinking water; however, commercial laboratories offer analyses of these media using in-house developed methods that are based on EPA Method 537. Development of procedures to assess the total organofluorine in environmental waters and soil and sediment are needed to help assess transformation and distribution of PFAS, as well as to assess various aspects of PFAS remediation techniques.
In 2019, SERDP began funding a group of projects to develop standardized analytical and environmental sampling methods for PFAS in the subsurface. Described below are the five projects that were selected for funding, which includes two projects that are one-year, proof-of-concept approaches.
Summaries of these research projects are available on the SERDP and ESTCP website and all reports originating from these efforts will be available from the project web pages.
