There are over 10,000 military and civilian aqueous film forming foam (AFFF) delivery systems in aircraft hangars and firefighting vehicles that may require prudent remediation to avoid ongoing environmental impacts from residual per- and polyfluoroalkyl substances (PFAS) within those systems. While fluorine free alternatives for AFFF are being introduced, PFAS persistence and rebound within AFFF systems will likely result in continued PFAS discharge long after initial cleaning attempts. Anecdotal and vendor supplied cleaning methods can be insufficient for PFAS levels of concern. Therefore, current operations may need adjustment to meet challenges presented by PFAS.

Researchers from EPA and the U.S. Air Force Institute of Technology evaluated PFAS remediation scenarios and developed site-specific strategies through a combination of bench-scale studies, a simulated hangar system, and hydraulic modeling. This webinar will provide data and information to refine existing cleanup guidance for remediating PFAS contaminated foam delivery systems, specifically those in hangars and Aircraft Rescue and Firefighting vehicles, potentially leading to substantial cost savings.
