Firefighting foams made without “forever chemicals” take longer to extinguish flames, but they can work, scientists said Wednesday at a Pentagon environmental research conference.
The Defense Department is spending millions of dollars researching fluorine-free firefighting foams. The goal is to find substitutes for the foams it now uses that contain per- and polyfluoroalkyl substances, also called PFAS and dubbed “forever chemicals” for their environmental longevity.
Research continues on how alternatives to PFAS-free foams perform and affect people and the environment, so conference speakers declined to name the leading candidates that could help the Department of Defense put out jet fuel ...
