Everyone should be watching the PFAS campaigns. The EPA has, this year, revised acceptable levels of PFAS in water down to parts per billion, meaning nearly undetectable levels. This will be used to deem public water supplies unsafe and make mitigation costs ruinous. Every public water system will be tested and most will fail, since PFAS has been in our supply system for decades and is still commonly used in many products. Schools and other high-use areas will be tested, too, and fail, and taxpayers can pay for remediation there too. Standing against PFAS mitigation will make you look crazy to your neighbours.
PPT, you're right of course -- way undetectable indeed.
I've been watching this campaign unfold (be paid for) for about 9 months and wondered where it was going. This WEF vid is a good possible explanation.
PFAS is in the stage where a mass of explainer articles ("What You Need to Know about PFAS") are slowly but steadily being seeded to low-information outlets.
If you can stomach the patronizing Karen tone, the videos embedded in these two pages give a good idea of the stance ("be very concerned" ... "It's going to be very expensive.")

I like to run a news search in PFAS every so often and see where the narrative's at and who's running headlines.
