The objective of this Statement of Need was to develop improved forensic methods and tools for source tracking and allocation of per- and polyfluoroalkyl substances (PFAS). Specific areas of interest were as follows:

• Evaluation of conventional or novel analytical techniques or methodologies to differentiate PFAS from aqueous film forming foam (AFFF) versus non-AFFF sources.
• Develop spectral libraries of PFAS to include both AFFF-derived PFAS as well as PFAS derived from other sources (i.e., consumer products, utilization in industrial manufacturing processes, landfill leachate, etc.).
• Improved analytical methods and/or validated models to predict changes to AFFF mixtures over time, including chemical pathways to the most toxic compounds.

Proposals should have addressed one or more of the objectives listed above. To provide strategic guidance for future research and demonstrations on management and remediation of AFFF- impacted sites, SERDP and ESTCP conducted a workshop on May 2-3, 2017 in Washington, D.C. Proposers were strongly encouraged to view the Workshop Report summarizing the research, demonstration, and technology transfer needs prior to submitting their proposal.

Funded projects will appear below as project overviews are posted to the website.
