Water Testing Homepage

  • Water Quality in Santa Clara Unified School District

    Under new California State regulations, including Assembly Bill 746, community water systems in California are testing for lead in drinking water at pre-kindergarten to twelfth-grade school sites in the state’s public schools. Lead and copper in water frequently originate from the corrosion of plumbing materials which allows the metals to leach into tap water.

    In late 2017, we began working with our local water agencies in the cities of San Jose, Santa Clara, and Sunnyvale, to test water samples from drinking fountains and faucets used for food-preparation at all of our schools. Our water agencies are testing five outlets at each site without charge to the district.

    We are fortunate to have local bond funding that has kept our facilities renovated and modernized to ensure that our campuses are well maintained and updated. As a result, we have been pleased to find that preliminary test results are quite encouraging. This webpage is designed to provide an overview of our lead testing results with updates when we receive them.

    About Lead Levels

    Assembly Bill 746 sets a regulatory reporting and action level of 15 parts per billion (ppb) (or 15 micrograms per liter) for lead in drinking water in schools.

    According to State Water Resources Control Board recommendations, if the lead level in a first-draw drinking water sample collected on a drinking water fixture at the school campus “exceeds 15 ppb“, the fixture must be removed from service and, if corrective action is taken, the fixture should be re-tested to confirm the lead level in water is not higher than the action level before being returned to service. School communities must be informed of any such lead findings and, as part of the investigation, water at the main entry point to the school campus must be tested.

    Our SCUSD Protocol

    To ensure the health and safety of our students and staff, we are following the recommendation of the American Academy of Pediatrics and plan to take any fixture that tests at 5 part per billion or higher (above the "non-detect" level) out of service until the source is identified, remediated, and then retested.

Testing and Reporting Timeline

  • Plan for Testing and Action on Fixtures:

    1. Remove from service any fixture that tests at 1 ppb or above
    2. Identify the cause of contamination 
    3. Remove the fixture
    4. Remediate the fixture
    5. Re-test before returning the fixture to service
