FY 2023 STATEMENT OF NEED
Environmental Restoration (ER) Program Area
The objective of this Statement on Need (SON) was to develop an improved understanding of transformation processes for polyfluoroalkyl substances (aka “precursors”) in the subsurface at aqueous film forming foam (AFFF)-impacted sites. Specifically, the goal was to address the following research needs:
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 risk assessment and site management decisions by providing knowledge of the ubiquity with which transformation processes occur, rates of transformation, how those rates potentially change over time, and the relevant terminal perfluoroalkyl acid (PFAA) transformation products.
