Vapor Intrusion Mitigation System – Palo Alto, CA

Terra-Petra’s Environmental Engineering Division has partnered with a significant environmental consulting firm in the Bay Area to prepare a comprehensive Vapor Intrusion Mitigation System (VIMS) for a new development located in Palo Alto, CA.

Terra-Petra designed the passive mitigation system with the ability to convert it to an active system in the future if deemed necessary. The VIMS System was reviewed and approved by the Department of Toxic Substances Control (DTSC).

Having completed the VIMS design we have moved on to the construction administration phase which includes submittal review and RFI responses, as well as the QA/QC inspections. We are currently on-site overseeing the smoke testing of the subslab membrane system.
