Environmental Restoration (ER) Program Area 

The objective of this limited-scope Statement of Need (SON) was to address specific knowledge gaps identified in the May 2017 SERDP and ESTCP Workshop on Management of Aqueous Film Forming Foam (AFFF)-Impacted Sites. The intent was to collate and analyze existing data on per- and polyfluoroalkyl substances (PFAS), not to conduct additional experimental work. Proposers were asked to address the following objectives:

  • Develop an approach for assessing PFAS risks to threatened and endangered (T&E) species at AFFF-impacted sites, associated exposure factors for PFAS, and suitable surrogate (non-T&E) species. 
  • Form the basis for innovative, on-site technologies for concentrated PFAS waste streams.
  • Define lines of evidence for assessing effectiveness of proposed remediation technologies.

The projects listed below were selected to address the objectives of this SON. Additional information on individual projects can be found by clicking the project title.

Research will assist in improved, data-driven remediation decisions for AFFF-impacted sites.
