Vapor mitigation allows for animal shelter development

TerraShield Installation Leads to Development of Animal Welfare Facility

A local animal welfare organization needed a new building and outdoor space to provide a state-of-the-art center for animal care in an urban community. United Consulting, a multi-disciplinary engineering and environmental consulting firm based in Georgia, was engaged to develop a plan for remediating the soil impacts and assessing vapor intrusion risk at a prospective site. Methane was identified in the vapor phase, requiring mitigation to reduce the vapor intrusion risk. United Consulting specified TerraShield due to its high level of protection against contaminant vapor intrusion. With the building protected from vapor intrusion by TerraShield, the facility workers, prospective pet foster parents, and the animals are ensured a safe breathing environment.

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.
