Lead Sampling Information for Schools

In 2017, the Governor signed into law Assembly Bill 746 (AB 746), adding Section 116277 to the Health and Safety Code (HSC 116277), and the State Water Resources Control Board - Division of Drinking Water (DDW) issued permit amendments to public water systems related to requirements for testing of lead levels of drinking water at schools. Combined, these two mandates require the testing of lead levels of drinking water at California K-12 public schools, preschools, and child day care facilities located on public school property constructed before January 1, 2010. Testing for schools on public property must be completed by July 1, 2019. Lead sampling of drinking water at private schools remains voluntary and requests for sampling must be completed by November 1, 2019.

​​​ACWD requires a written request from a school official in order to initialize a sampling plan and to test the water at the most commonly used water drinking fountains.  A request template [Word Document] is provided for your convenience. Schools must be located within ACWD's service area. 

​Results from completed lead sampling from schools throughout California can be accessed on a map updated by DDW.  Please note that the map provided by the DDW is not updated with lead sampling results from child day care facilities on private property at this time.
