Schools must develop drinking water management plans within 16 months of enactment, specifying locations of filtered bottle-filling stations, filtered faucets, and water outlets not for human consumption

Minimum of one filtered bottle-filling station required per 100 school occupants; all stations and faucets must be certified to NSF/ANSI standards for lead, PFOA, and PFOS reduction

Lead levels between 1-5 parts per billion trigger filter checks and retesting; levels above 5 ppb or PFOA/PFOS exceeding standards require immediate shutdown, parent notification within 30 days, and remediation planning with DPI

By August 1, 2027, schools must install all required filtration equipment, shut off unfiltered water outlets for human consumption, and post signage; new drinking fountains must be filtered bottle-filling stations

DPI must provide a plan template, annual training, and technical guidance within 7 months; grants may be awarded to schools for compliance costs, with DPI required to request supplemental funding from Joint Committee on Finance
