Utilities weigh advanced oxidation as contaminant limits tighten

Across the country, water utilities face tightening limits on uranium, arsenic, nitrate and PFAS. Conventional adsorption handles some of these expensively and incompletely, pushing operators toward advanced oxidation processes (AOP) that destroy rather than relocate contaminants.

Vendors report power-free, chemical-free configurations that fit existing footprints — a draw for small and mid-size systems without capital for new basins.
