Water Testing

As part of ongoing effort to improve and maintain healthy school environments, CVUSD voluntarily contracted with ACC Environmental Consultants, a Bay Area environmental company to conduct water quality tests at all school sites in August.  ACC Environmental Consultants gathered random samples from hundreds of fixtures and faucets throughout the district and has presented us the preliminary results. At a few locations the preliminary results showed lead levels above the recommended range, and we have taken immediate action to turn off the water at that station (sink or faucet) until the fixtures can be replaced and the water re-tested. Bottled water is available for students and staff as we work to address the problem.

Maintenance and Operations staff are working to address faucets and fixtures that require immediate replacement. Once complete, we will conduct a full assessment of any site that had an identified water testing finding. If there are any subsequent findings, we will work to resolve them next. For school sites with no identified findings in the first round of testing (August 2017), we will complete a full assessment after all issues are addressed at the other sites.  Additionally, we are working to install hydration stations at all sites regardless of findings. Ongoing updates about projects funded by Measure G, which includes health and safety as a top priority, will be shared with the community on an ongoing basis. The report is available here

Questions and Answers on District Water Testing

  • What is the timeline on replacement impacted faucets?
    • Parts have been ordered and we expect to have them and to be able to replace them within the next few weeks. Until then we have bottled water available. In accordance with Environmental Protection Agency (EPA) guidelines, it is a good practice to flush water faucets and fountains by running the water for thirty seconds before use. As an extra precaution, we are sharing this information with our staff and ask that they utilize this practice.
  • What is the timeline for conducting a full assessment of the entire district?
    • For the school sites identified in the draft report, we will complete a full water quality assessment as soon as possible. This process may take several months to complete.
  • What about classrooms that still have water access in the identified fixtures? Is that water okay for students to use?
    • The full assessment will provide us the necessary information. Until then, we recommend everyone to follow the EPA guideline of running the water thirty seconds before use. Bottled water is available.
  • What is the normal recommended range?
    • The normal range is less than fifteen (15) parts per billion (PPB).
  • How is changing the fixtures going reduce the lead in the water?
    • Although every attempt is made to reduce contaminants, replacing fixtures and faucets will not eliminate all lead in the water. By installing new faucets and fixtures we will be reducing lead to acceptable ranges.
  • Which sites were identified as having a few faucets and fixtures that need to be addressed?
    • Random voluntary tests were conducted in August 2017. Fountains and faucets were not used all summer, which could have impacted the results, increasing the possibility of higher levels of lead showing up in random tests.   All sites were randomly tested and after 300+ samples, the draft  report indicated the following locations require corrective action:
      • Canyon Middle School- none
      • Castro Valley Adult School- none
      • Castro Valley Maintenance Yard- none
      • Castro Valley Pre-school- none
      • Castro Valley Elementary- 1 fixture  
      • Castro Valley High School- 1 fixture  
      • Chabot Elementary- 4 fixtures
      • Creekside Middle School- 4 fixtures
      • District Office- none
      • Independent Elementary- none
      • Jensen Ranch Elementary- 2 fixtures
      • Marshall Elementary- none
      • Palomares Elementary- 4 fixtures
      • Proctor Elementary- none
      • Stanton Elementary-4 fixtures
      • Vannoy Elementary- 2 fixtures
      • Redwood High School- 3 fixtures
