The New York State Department of Health announced proposed regulations for PFAS in drinking water systems, establishing Maximum Contaminant Levels (MCLs) for 23 additional emerging contaminants. The proposed regulations are amendments to Public Health Law signed by Governor Kathy Hochul and represent the Department's effort to address emerging contaminants including per- and polyfluoroalkyl substances (PFAS). PFAS break down slowly in the environment and have contaminated drinking water supplies leading to exposure and health concerns.
