Requires certain residential property owners, schools, and child care centers to test drinking water for lead every three years.

This bill requires owners of pre-1987 residential buildings with three or more units, schools, and licensed child care centers to test drinking water for lead every three years. Testing must be done by certified labs, with at least one sample per occupied unit (or random sampling for buildings over 10 units). If lead levels exceed EPA standards, owners must notify tenants, parents, staff, and local health officials, and schools/child care centers must post results online. The law applies to all qualifying properties, with existing testing requirements exempting some properties under prior law.
