"'There’s also a lot of interest in having firefighters use foams that don’t contain PFAS, not just to protect the firefighters, but also because the PFAS foams have contaminated a lot of groundwater and drinking water across the U.S.,' said study co-author Ruthann Rudel, research director at Silent Spring Institute.
Because many manufacturers do not disclose the ingredients contained in firefighting foam, the project GreenScreen has recently launched a certification program to identify PFAS-free foams, Rudel pointed out."
