Water supply: quality and standards; effective date of the clean drinking water access act; revise. Amends secs. 5 & 7 of 2023 PA 154 (MCL 380.1905 & 380.1907).

HB 5507 amends Michigan’s Clean Drinking Water Access Act to require all public schools to implement stricter lead testing and filtration for drinking water. Schools must create a management plan within 24 months, install filtered bottle-filling stations (1 per 100 occupants) or filtered faucets in specific areas, and conduct annual lead testing to ensure levels stay below 5 parts per billion. If lead exceeds 5 ppb, schools must immediately shut off the source, notify parents, and develop a remediation plan. Full compliance, including shutting off non-filtered water outlets, is required by the 2028-2029 school year, contingent on state funding appropriations.
