Lead Testing for Child Day Care Facilities

Assembly Bill 2370 (AB 2370) requires all licensed child day care and preschool facilities located on private property in California to test for lead levels in their drinking water.  AB 2370 requires licensed child day care facilities which are located in a building that was constructed before January 1, 2010, to have its drinking water tested for lead contamination levels on a specified schedule and to notify parents or legal guardians of children enrolled in the day care center of the requirement to test the drinking water and the results of the test. If a licensed child day care center is notified that it has elevated lead levels, AB 2370 requires the day care center to immediately make inoperable and cease using the affected fountains and faucets and obtain a potable source for water for children and staff. ​​Testing for lead levels in drinking water must be conducted between January 1, 2020 and by the end of 2022. ​​Day care facilities are responsible for the cost of testing and any subsequent repairs. ​​
