Unfortunately, PFAS sticks around forever, so everywhere that the old firefighting foam was deployed (e.g. air force bases) still has high levels of PFAS contamination.

So avoid using dry teflon lubricant spray? Will do!
There was a scare in 2024 where high levels of PFAS were found in the water supply in the Blue Mountains region of NSW. It took months, but they traced it to a single fire in 1992 where foam was deployed. Scary stuff.
