Environmental Restoration (ER) Program Area 

The objective of this Statement on Need (SON) was to develop cost effective remedial technologies for matrices impacted by per- and polyfluoroalkyl substances (PFAS) resulting from the use of Aqueous Film-Forming Foam (AFFF) formulations. Specifically, the goal was to address the following research needs:

  • Develop cost effective treatment approaches for PFAS-impacted matrices, including but not limited to groundwater, soils, aquatic sediments, spent media, and AFFF concentrates.
  • Develop cost effective approaches for complete destruction of PFAS bound onto spent media, regeneration of spent media, and treatment of associated ancillary waste streams.
  • Evaluate treatment technologies using field-impacted media containing PFAS mixtures and common environmental treatment complications.
  • Develop treatment train approaches that cost-effectively treat PFAS and facilitate treatment of co-occurring chemicals.
  • Conduct field monitoring events by partnering with pre-existing, commercial incineration facilities to document thermal destruction of PFAS within PFAS-laden soil, PFAS-impacted investigation-derived waste (IDW), spent GAC, and/or spent single-use ion exchange resins.

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 by facilitating the establishment of more cost-effective and efficient remedial action plans that are protective of human health and the environment. In addition, the remediation approaches will improve the reliability of treatment processes and expedite the cleanup closure of DoD impacted sites.
