The bill amends Chapter 46-12 of the General Laws, titled "Water Pollution," by introducing a new section, 46-12-42, which mandates testing of biosolids for PFAS contaminants. Applicants seeking approval from the Department of Environmental Management for the distribution or land application of biosolids must conduct these tests and submit the results with their application. Additionally, operators with existing approvals are required to test their biosolids quarterly for PFAS contaminants, starting from the October to December 2025 quarter, with the first results due by December 31, 2025.

Furthermore, the bill empowers the director of the Department of Environmental Management to reject any application for approval if it is determined that the distribution of biosolids poses an environmental threat or risks public health, safety, or welfare. This legislation aims to enhance environmental protection and public health by ensuring that biosolids are tested for harmful contaminants before being applied to land. The act will take effect immediately upon passage.
