Bill > A08634

This bill establishes strict maximum contaminant levels for certain per- and polyfluoroalkyl substances (PFAS) in drinking water. Specifically, the bill requires the 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. The bill also mandates the creation of a hazard index to address cumulative exposure to multiple PFAS chemicals, including PFNA, PFHxS, HFPO-DA, and PFBS. Public water systems will be required to comply with these new maximum contaminant levels and hazard index requirements by May 1, 2029. PFAS are a group of man-made chemicals widely used in various industries, known for their persistence in the environment and potential health risks. The bill aims to protect public health by significantly reducing allowable levels of these chemicals in drinking water, giving water systems approximately six years to implement the necessary treatment and monitoring technologies to meet the new standards.
