VOC Risk Mitigated at Site of Former Chemical Manufacturer
This project snapshot features the following:
- TerraShield chosen as most protective, economical vapor intrusion mitigation solution for large logistics facility
- Future occupants protected against volatile organic compounds
- TerraShield successfully installed on time and within budget
A long-vacant San Francisco Bay Area brownfield was once the site of a former chemical plant that produced chlorofluorocarbons, fuel additive anti-knock compounds, and titanium dioxide from 1956 to 1997. With onsite rail service and more than three million households within 50 miles, the property was considered a prime location for a new 2.2 million square foot logistics development. However, the site’s prior industrial history left residual volatile organic compounds (VOCs) in the subsurface and posed a potential vapor intrusion risk. Following a cost-benefit analysis and thorough evaluation of contaminant vapor barrier systems available, TerraShield® Metalized Nitrile Contaminant Vapor Barrier was selected for the new logistics building.
