Firefighting foam trials present next big PFAS challenge for 3M
News
1 Oct 2022 | Star Tribune
But the miracle firefighting foam's key ingredient was one of the "forever chemicals" that have come to haunt 3M. PFAS chemicals don't biodegrade, tainting the environment. They have been linked to cancer, liver damage, decreased fertility and other maladies.
