Continuous Monitoring - Thermal Heating Remediation site - Oakland, CA - Case study

Date Conducted: Feb 2017 – ongoing
Client: OTIE
Oversite Agency: EPA Region 9
Project Description: Continuous monitoring of indoor and ambient air for vinyl chloride, TCE and PCE at 14 locations across and bordering a site undergoing thermal heating remediation. This is the first time that vinyl chloride in air has been measured in real time. Data were collected prior to heating and during heating to ensure the vapor recovery system was performing adequately and make adjustments based upon the real-time data. As of September 2017, approximately 25,000 measurements of vinyl chloride, TCE and PCE have been collected. Data are available in real time to the client and EPA and also automatically uploaded to EPA’s Viper database software.
