"Researchers are seeking a breakthrough in technologies to tackle PFAS contamination," reports the Washington Post — including experiments with ultraviolet light, plasma and sound waves:"We're in a good spot," said Christopher Higgins, a professor of civil and environmental engineering at the Colorado School of Mines who researches PFAS. The process used in a patented technology created by Battelle produces carbon dioxide and a form of fluorine that can be quickly neutralized to become a harmless salt. Known as hydrothermal alkaline treatment, or HALT, it involves adding a low-cost chemical reagent such as sodium hydroxide to superheated liquid water.... A destruction method that harnesses ultraviolet light has also emerged as a contender [ has licensed by a company in Michigan].
