In 2019, scientists studying the persistent pollutants uncovered new information about their impact, how they cycle in the environment, and what it will take to get rid of them. Development continued on a battery of potential treatment methods, including new adsorbents that better target PFAS and destructive technologies aimed at demolishing the strong C–F bonds that make PFAS so persistent. Chris Higgins, who studies emerging contaminants at the Colorado School of Mines, says he expects this “every tool on the table” approach to continue. “It’s such a big liability; you don’t want to put all your eggs in one basket,” he says. After a few years in the pipeline, some technologies have cleared important milestones on the road to large-scale use.
