Transformation of Polyfluoroalkyl Substances Found in Soil and Groundwater at AFFF-Impacted Sites
SERDP, Environmental Restoration Program Area
The objective of this Statement of Need 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. Specific research areas of interest included:
Identification of microbiological and/or abiotic processes and pathways capable of either transforming or degrading AFFF-relevant precursors.
Evaluation of relevant environmental factors that affect transformation rates such as subsurface geochemistry, soil chemical/physical properties, nutrient availability, etc.
Development of methodologies and/or molecular biological tools to assess or predict the extent and rate of in situ transformation under ambient field conditions.
Proposals should have addressed one or more of the objectives listed above. Research and development activities at laboratory-, bench-, and field-scale were considered. Work did not necessarily have to culminate in a field-scale effort.
Funded projects will appear below as project overviews are posted to the website.
