This SERDP and ESTCP webinar focuses on DoD-funded research efforts to develop approaches for remediating AFFF-impacted fire suppression systems. Specifically, investigators will cover a rinsing procedure to remove PFAS from AFFF delivery equipment, evaluation of a closed-circuit high-pressure nanofiltration/reverse osmosis system for the concentration and treatment of AFFF residuals, and laboratory and field demonstrations for removing PFAS entrained on surfaces.
