Continuous Monitoring – Thermal heating remediation site – New Hampshire - Case study

Date Conducted: June 2016 to January 2017
Client: Hull & Associates
Oversite Agency: EPA Region 1, NH-DEH
Project Description: Continuous monitoring of indoor and ambient air for TCE and PCE at 15 locations inside an active manufacturing facility at a site undergoing thermal heating remediation. Data were collected prior to heating and during heating to ensure the vapor recovery system was performing adequately. The system ran uninterrupted for over 7 months and approximately 30,000 measurements of TCE and PCE were collected. Data were available for viewing by the property owner, consultant, and EPA in real time on the web. The system enabled unexpected detections of TCE to be instantly recognized and tracked down to indoor air sources.
