Lawmakers in California advanced a bill through the Assembly in May on a 59-0 vote that would mandate clean water for tenants in locations served by domestic wells.
Assembly Bill 2454, authored by Assemblyman Alex Lee, would require landlords with renters who rely on private wells to test the water annually—using free domestic water testing programs if available—and share results with tenants within 10 days. If the water fails to meet quality standards, an adequate supply of clean drinking water must be provided within 14 days.
