Establishes maximum contaminant levels in drinking water for certain per- and polyfluoroalkyl substances (PFAS).

This bill amends the public health law to establish maximum contaminant levels in drinking water for specific per- and polyfluoroalkyl substances (PFAS). It sets the maximum levels at no higher than 4 parts per trillion for perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA), and no higher than 10 parts per trillion for perfluorononanoic acid (PFNA), perfluorohexane sulfonate (PFHxS), and hexafluoropropylene oxide dimer acid (HFPO-DA, also known as GenX). The commissioner is required to ensure public water systems comply with these levels by May 1, 2029.
