FY 2018 STATEMENT OF NEED
Environmental Restoration (ER) Program Area
The objective of this limited-scope Statement of Need (SON) is to develop innovative approaches for treatment of investigation-derived waste (IDW) from investigations of per- and polyfluoroalkyl substance (PFAS) impact in the subsurface. This IDW largely consists of excess soil cuttings, purge water from groundwater sampling, and fluid from decontamination of drilling equipment that are impacted at varying levels with PFASs as well as potentially many other traditional CERCLA and RCRA compounds. The preference is for destructive technologies that treat the IDW rather than rely on landfilling so as to avoid potential future environmental liability given that disposal requirements for PFASs are evolving. 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 sites, specifically for residual 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.
