The bill amends section 6111.041 and enacts section 6109.26 of the Revised Code to enhance the regulation of drinking water contaminants in Ohio. It mandates the Director of Environmental Protection to establish maximum allowable contaminant levels (MCLs) for specific harmful substances, including per- and polyfluoroalkyl substances (PFAS), chromium-6, and 1,4 dioxane. The bill outlines the definitions of MCLs and PFAS, and requires the director to consider standards set by other states, scientific studies, and federal guidelines when adopting these rules. Additionally, the director is tasked with ensuring that the established MCLs are protective of public health, particularly for vulnerable populations such as pregnant women and children.

Furthermore, the bill requires the director to adopt water quality standards for the same contaminants, ensuring they are not less stringent than federal standards. The director must conduct annual reviews of these standards and amend them as necessary based on the latest scientific research. The existing section 6111.041 is repealed, and the new provisions aim to improve the quality of Ohio's water resources while safeguarding public health.
