This bill appropriates funds to the Department of Environmental Services for various water infrastructure projects. Specifically, it allocates $50,000,000 for the remediation of per- and polyfluoroalkyl substances in the state's drinking water and wastewater, with $5,000,000 designated as a grant for the Southern New Hampshire Regional Water Interconnection Project, Phase 2B. Additionally, it provides $325,000 to the Pillsbury Lake Village District for water system upgrades, which includes piping upgrades, water filtration improvements, and other system enhancements. The state treasurer is authorized to borrow up to $50,000,000 to support these appropriations.

The bill also includes specific amendments to existing law, such as the deletion of references to "loan" costs associated with the upgrades for the Pillsbury Lake Village District, replacing it with a broader term "water system improvements." Furthermore, the language regarding the development of a new well has been changed to reflect a more general approach to water system improvements, emphasizing collaboration between the Department of Environmental Services and the Pillsbury Lake Village District. The act is set to take effect on July 1, 2026.
