Project snapshot highlights:

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.

Featured Case Study: Cross-Team Collaboration Moves New Public Library and Town Hall Complex Forward

A growing community near Charlotte, North Carolina was seeking a site to construct a new town hall and public library complex. SUMMIT Engineering, Laboratory & Testing, P.C. (SUMMIT) conducted an environmental assessment at the property in April 2020, confirming that petroleum hydrocarbon (PHC) contamination was present. SUMMIT recommended installing a vapor intrusion mitigation system (VIMS) to the property development team, knowing it would be the most effective approach to address PHC contaminant vapors. In considering their options, Nitra-Seal, a state-of-the-art VIMS offering proven chemical resistance and vapor intrusion protection, was selected by the development team.

Introducing a New Advanced Nitrile Composite Vapor Barrier System

Nitra-Seal is an update/improvement on current vapor barrier systems. Originally, passive vapor barrier systems were waterproofing systems adapted for use as contaminant vapor barriers. An acknowledged weakness in these systems is in the penetration and perimeter termination locations, where spray-applied core material composed of Styrene-Butadiene (SBR)- modified asphalt is used. While excellent at repelling water, aggressive chemicals such as petroleum solvents and chlorinated volatile organic compounds (VOCs), will permeate into the SBR-modified asphalt at a relatively high rate particularly in sensitive areas of the building construction such as barrier seams, slab penetrations and perimeters. Nitra-Seal offers a substantial upgrade as it employs a more chemically resistant nitrile latex instead of the more susceptible SBR material. Nitrile is recognized throughout the environmental engineering industry as being more chemically resistant than rubber or SBR and is often used in personal protective equipment when working on hazardous waste sites (e.g. nitrile gloves).

In this live European webinar, Blayne and Tom discuss the challenges of vapor intrusion assessments and the benefits of continuous monitoring. They are joined by Rick Gillespie, Senior Vice President of Land Science, the vapor mitigation division of REGENESIS.

With vapor intrusion assessments, typically only a few contaminant concentration measurements are made, so it is often difficult to reach a conclusion if the vapor intrusion pathway is a concern. The result is that vapor intrusion investigations can drag on for months to years before a conclusion can be reached regarding the potential risk. Such time periods are unacceptable if there is a potential risk to human health.

For Patrick Lowery, Sr. Environmental Manager with SUMMIT Engineering, Laboratory & Testing, Inc., a multi-disciplinary environmental consulting firm and valued Land Science® client, a career in environmental remediation was sparked by an interest in geology, a field his grandfather worked in. Lowery initially planned to follow his grandfather’s path and become a geologist, but then realized his true passion involved assisting in the cleanup of our planet. He shares, “My grandfather was a geologist for Shell Oil in the Permian Basin, near Midland Texas. Throughout college my focus was to work in the petroleum industry. I took a year off from school after earning my Bachelor of Science in Geology from the University of Alabama and was going to attend Colorado State University for my Masters in Geophysics, however, while working with a consulting geologist that year I found I enjoyed the environmental field.”

Featured Video: Nitra-Seal Applied as Preemptive Vapor Mitigation Solution for Town Hall and Library Complex

A growing community near Charlotte, North Carolina was seeking a site to construct a new town hall and public library complex. The city planners had identified a land parcel that would meet the spatial requirements for the new complex, but the site was a former gasoline service station which operated on a portion of the land for nearly two decades. As part of the City’s due diligence, a Phase I Environmental Site Assessment (ESA) was completed and revealed the underground storage tank (UST) system was decommissioned in 1991 with the tanks abandoned in place. However, no records existed which documented environmental conditions at the time of UST removal. Consequently, the USTs were listed as a recognized environmental concern (REC) in the Phase I ESA. In early 2020, a geotechnical investigation identified soil with odors and elevated photoionization detector (PID) readings, a further indication of petroleum hydrocarbon (PHC) contamination in the subsurface.

Featured Case Study: TerraShield Protects Future Occupants from Harmful Vapor Intrusion

A large automotive and supply company planned to build its new corporate headquarters on a 4.5-acre brownfield site recently acquired in Southfield, MI. Soil and groundwater sampling on the property revealed the presence of trichloroethylene (TCE) and polynuclear aromatic hydrocarbons (PAHs). TCE was also identified in soil gas beneath the site. Within the footprint of the planned building itself, contaminant concentrations were found to be in excess of applicable indoor air quality screening levels. The developer utilized brownfield funding from the local authority to conduct the necessary environmental remediation measures.

Featured Project Snapshot: Leading Hotel Chain Moves Forward With Brownfield Site Construction Following Installation of Vapor Barrier System

The project site is a modern, climate-controlled self-storage facility that includes all-in-one moving, packing, and storage services for its customers. The building was developed on a former industrial brownfield at the site of a former factory. As part of Maryland’s Voluntary Cleanup Program, the environmental consultant completed a Phase II investigation, finding elevated chlorinated solvent contaminants in the soil gas. The Maryland Department of Environment required the installation of a vapor mitigation system over a portion of the building. However, in working with the consultant, it was ultimately determined that a vapor barrier spanning the entire building footprint would be necessary to protect the future building tenants fully. Based on chlorinated solvent concentrations, TerraShield® was specified to provide the highest level of chemical resistance and long-term barrier performance available on the market. The project required active venting and a site-specific design, leveraging Land Science’s vapor barrier design expertise. Additionally, the TerraShield vapor mitigation system included an extended material warranty to provide the project stakeholders added assurance that building occupants would be protected long into the future.

Superior Chemical Resistance Over Any Vapor Barrier on the Market Today

Nitra-Seal Applied as Preemptive Vapor Mitigation Solution for National Restaurant Chain

This project development site is a newly opened quick-service restaurant in Conyers, Georgia. Offsite chemical spills from historical operations had resulted in low-level volatile organic compounds (VOCs) released to the subsurface, creating a potential for vapors to intrude into new buildings constructed in the affected area. Recognizing the risk and placing emphasis on future workers’ safety, the forward-thinking client decided that a preemptive measure be instituted, requiring the installation of a vapor mitigation system as part of the construction specification.

Introducing a New Advanced Nitrile Composite Barrier System

Nitra-Seal is an update/improvement on current vapor barrier systems. Originally, passive vapor barrier systems were waterproofing systems adapted for use as contaminant vapor barriers. An acknowledged weakness in these systems is in the penetration and perimeter termination locations, where spray-applied core material composed of Styrene-Butadiene (SBR)- modified asphalt is used.
