Water supply: quality and standards; clean drinking water requirements in schools and child care centers; modify. Amends secs. 3, 5 & 7 of 2023 PA 154 (MCL 380.1903 et seq.).

This bill amends Michigan's Clean Drinking Water Access Act to establish stricter water quality standards for schools and child care centers. It requires these facilities to create drinking water management plans within 15 months that map out water outlets and schedule regular testing and filter replacements. The law mandates filtered bottle-filling stations for every 100 occupants and requires all water fixtures to meet specific lead reduction standards, with schools taking immediate action if lead levels exceed one part per billion.
