Researchers Detail UV Light Mechanism for Breaking Down PFAS Chemicals

Scientists at the University of California, Riverside, have identified the specific chemical reactions by which ultraviolet (UV) light can effectively degrade per- and polyfluoroalkyl substances (PFAS) in water. Published in Nature Water, this research clarifies the chemistry behind UV-driven treatment, demonstrating its ability to convert these persistent "forever chemicals" into fluoride. This understanding is crucial for improving methods to clean up widespread PFAS contamination.
