FY 2018 STATEMENT OF NEED

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.

• A Framework for Assessing Bioaccumulation and Exposure Risks of PFAS in Threatened and Endangered Species on AFFF-Impacted Sites
  • Lead Investigator: Frank Gobas, Simon Fraser University
• Guidance for Assessing the Ecological Risks of PFAS to Threatened and Endangered Species at AFFF-Impacted Sites
  • Lead Investigator: Jason Conder, Geosyntec Consultants
• Establishment of Fate and Transport Mechanics for PFAS under Controlled Aquifer Conditions and Correlation to Existing Data
  • Lead Investigator: Brian Shedd, USACE, Baltimore District, Geology and Investigations Section
• Investigating Potential Risk to Threatened and Endangered Species from PFAS on DoD Sites
  • Lead Investigator: Jamie Suski, EA Engineering, Science, and Technology, Inc., PBC
• Lines of Evidence to Assess the Effectiveness of PFAS Remedial Technologies
  • Lead Investigator: Rula Deeb, Geosyntec Consultants
• Approach For Assessing PFAS Risk to Threatened and Endangered Species
  • Lead Investigator: Craig Divine, Arcadis US Inc.

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