Of course DuPont manufactures their own treatment system. Of course they do. Which is fine but they should all be manufactured, distributed, and used as charity/penance. Yeah, 25-life with a tramp stamp labeled "sensitive receptor".Mind boggling how this was able to go on for so long. Company town mentality still runs strong in parts of the country. I see it on my work travels. DuPont C-suite occupiers and BOD officers need to go into big boy general population in a Federal Penitentiary for 25-life for this crime.
It's all pump and treat at this point and will be for a long, long time for the reasons you list.... I have a friend/former colleague who saw this coming a few years back and has timed the market perfectly and is making a killing with his patented GAC systems.
Ironically, Dupont is in the water treatment business and has an ion exchange system PFAS for PFAS removal.
AWWA has updated their curriculum to include PFAS and the topic now has it's own tract at most conferences. It still amazes me that it took as long as it did to gain meaningful traction.
Between DuPont and other chemical manufacturers and energy producers, forget society, they owe a massive debt to the species. If peasants could stay in the horseshoe business (or whatever) for 20+ generations, those C-suiters and their scions can be in the front lines of environmental cleanup for the same period of time or until the job is done.
Not just PFAS, humans can't even eat a lot of fish anymore because of the high mercury content. Step back and think how terrible that truly is:
The food chain for our species was disrupted so a few people could make an exorbitant amount of money.
Clearly the answer is that we should cut corporate taxes and ignore any concept of a wealth tax.
