Two years ago Assembly Bill 746 required all California K-12 public schools built before 2010 to test for lead in drinking fountains and faucets by July 1, 2019. So far, 1,256 of 7,188 schools tested by the California State Water Resources Control Board (17 percent) have reported levels of lead that exceed five parts per billion (ppb). The American Academy of Pediatrics recommends that lead in school drinking fountains not exceed 1 ppb, whereas the Centers for Disease Control and Prevention says there is no blood lead level for children that can be considered safe.
