Managing AFFF Impacts to Subsurface Environments and Assessment of Commercially Available Fluorine-Free Foams (Web-based)
The historical use of aqueous film forming foam (AFFF) formulations containing per- and polyfluoroalkyl substances (PFAS) for firefighting and training activities by the Department of Defense (DoD) has led to concern over the potential for contamination of groundwater at hundreds of sites. This presentation will present viable approaches for treating recalcitrant PFAS and recent related research activity. Technologies of particular focus include sorption, ion exchange, oxidation, sonolysis, and plasma treatment. Challenges and limitations of these approaches, including the presence of precursors and co-contaminants and generation of byproducts will be discussed. The presentation will also highlight research activity at Clarkson University to advance and optimize PFAS treatment technologies, with a particular emphasis on treatment trains for more efficient and effective remediation.
