Bill > S03207

This bill establishes stringent maximum contaminant levels for certain per- and polyfluoroalkyl substances (PFAS) in drinking water, which are synthetic chemicals widely used in industrial and consumer products. Specifically, the bill requires the New York State Commissioner of Health to set maximum contaminant levels at 4 parts per trillion (ppt) for PFOS and PFOA, and 10 parts per trillion (ppt) for PFNA, PFHxS, and HFPO-DA, which are known for their persistence in the environment and potential health risks. Additionally, the bill mandates the development of a hazard index to address cumulative exposure to multiple PFAS chemicals, including PFNA, PFHxS, HFPO-DA, and PFBS, recognizing that the combined impact of these chemicals may pose greater health risks than individual exposure. Public water systems in New York will be required to comply with these new maximum contaminant levels and hazard index by May 1, 2029, providing a significant timeframe for water utilities to implement necessary treatment technologies and monitoring systems to meet the new standards. The bill will take effect one year after becoming law, with immediate authorization for developing the required regulations.
