This SERDP and ESTCP webinar focuses on DoD-funded research efforts to develop PFAS-free firefighting foams. Specifically, investigators will discuss research into surfactant transport and its applicability to both firefighting foams and bilgewater emissions, and the development of fluorine-free siloxane containing and alkypolyglycoside surfactants to develop an optimized firefighting mixture. There will be two presentations titled: 1) "Surfactant Transport at Fluid-Fluid Interfaces, from Bilgewater Emulsions to Firefighting Foams" and 2) "Drop-in Synergistic Surfactants and Additives for Effective Pool Fire Suppression".
