Scientists Discover Way to Destroy Harmful “Forever Chemicals” in Water Supply
New technology could help water utilities remove stubborn PFAS chemicals linked to cancer and other maladies.

This is very interesting. Currently, most ion exchange systems that remove PFAS have to dispose of their brine as hazardous waste, which is very costly and doesn't necessarily destroy PFAS - in Florida, for example, they inject the brine into a deep aquifer.
A lot of novel technologies target PFAS destruction in these concentrated waste streams, but often further concentration is required before you can effectively destroy PFAS with advanced oxidation processes. If they could use low-UV to destroy it without further concentration or additional chemicals (beside the salt already used to regenerate the resin), ion exchange would become a much better solution for treated PFAS contaminated water.
