Search lead test results in California school water

Lead levels above 15 ppb, the federal limit, require schools to replace faucets and notify parents.

Test results between 5 ppb and 15 ppb do not require action but pediatricians and other health advocates say they pose a health risk especially to children.

This group includes test results of 5 ppb or less. Health advocates say lead levels under 1 ppb are considered safe.
