PFAS are highly persistent in water and soil, creating a difficult, long-term contamination problem. The article argues that tackling this requires chemical-processing ingenuity: better detection and selective capture to limit spread, coupled with scalable, truly destructive treatments that mineralize PFAS, all while balancing cost, energy use, and tightening regulations. It emphasizes coordinated R&D across industry, utilities, and academia, along with developing PFAS alternatives and lifecycle-aware process designs.
