There is some evidence (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9228135/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9228135/) that PFAS causes trans-generational dysfunction. Even if we somehow get it out of our environment - which we will never do - the damage already done can stay with us indefinity. They not only poisoned several generations, they poisoned future ones as well. There is no amount of money that can be be paid here.

Having read the article it's really not clear this it supports that analysis, "As expected, environmentally relevant PFAS levels did not affect survival." In particular, although the high levels of exposure (of one or more PFOS/PFOA) showed effects, there was reverse correlation at low levels. Of course this is in Zebra fish so I'd hesitate to guess the relevance for mammal or human populations. It does seem to most directly affect lipid metabolism including steroids, and is multi-generational. I'd be most worried where the chemical (waste) byproducts were used as fire suppressants rather than the small quantities found elsewhere. Those concentrations (hundreds of ppt) are much more worrying. People who sprayed their clothes, couches, tires with scotchguard were probably also already exposed to 100s of times higher lifetime doses than they will ever see through environmental sources at <10ppt (still above proposed limits). https://www.ewg.org/interactive-maps/pfas_contamination/map/ https://www.ewg.org/interactive-maps/pfas_contamination/map/
