Tackling PFAS in drinking water | CBC News

Have we stopped the global production of PFAS? It is non-biogradable and thus cumulative in the environment and due to earth's natural hydrological cycle, it doesn't respect borders.
Filtering our drinking water while not banning it entirely and leading the charge to a global ban is just whistling past the graveyard.
Banning the production of all PFAS will take time. There are no alternatives to Teflon in many contexts, and many medical devices would simply not work if not for Teflon. A hard and immediate end to PFAS production would be devastating for medical care. It's a bit of a damned if you do, damned if you don't situation.
True, but medical devices are probably very very minor sources of pollution compared to textiles and firefighting foam. 80/20 rule is a clear step forward. Let's not artificially invent uneccessary arguments to stall progress.
The irony is, teflon is used extensively in water treatment and plumbing as well.
