FY 2018 STATEMENT OF NEED
Environmental Restoration (ER) Program Area
The objective of this Statement of Need (SON) was to improve our understanding of per- and polyfluoroalkyl substances (PFAS) in source zones resulting from the use of Aqueous Film Forming Foam (AFFF) formulations by the Department of Defense (DoD). In particular, the goal was to better understand the fate of precursor compounds and the role they play in sustaining perfluoroalkyl acid (PFAA) groundwater plumes, as well as the contribution to groundwater impact of residual PFAS mass in near surface soils. Ultimately, the ability to better characterize and model the nature of sources (and associated plumes) should lead to more targeted remediation strategies based on prioritizing areas posing the greatest risk. Specifically, the goal was to address the following objectives:
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 should lead to improved management of PFAS-impacted sites, specifically for residual chemical impact characteristic of aged source zones with particular emphasis on perfluorooctane sulfonate (PFOS)-containing AFFF agents. Products should provide tools and guidance to users (i.e., Remedial Program Managers) on effective management options for such sites. Further, this information will be used to support cost-benefit analyses of treatment methods and management strategies. The resulting tools and understanding should improve the ability to implement effective remedial strategies at DoD sites.
