Why Choose Thermal?

Eliminates Uncertainty

A remedial solution should be both certain and final. The ability to achieve performance-based goals is a testament to the reliability and predictability of our thermal technologies. Guaranteed fixed price contracts are available for most applications, and unlike other technologies, the application of thermal remediation eliminates "rebound" of contaminants. There is no place to hide: thermal remediation removes organic contaminants from a diverse series of lithologies, including clays, silts, sands, sandstone, and fractured rock - both below and above groundwater.

Fast and Definitive Treatment

Thermal remediation treatment times generally range between 8 to 32 weeks, after which residential target levels may be achieved in both ground water and soil. The exact duration of treatment time will depend on multiple factors, such as contaminant types treated, target temperatures, hydrology, and well spacing. A successful project begins with a proper design, and GEO completes a full numerical simulation and three dimensional thermal model for every project before implementation, guaranteeing a fast track to site closure.

Minimal Nuisances

No excavation, no dump trucks, no shoring, and no dust are necessary. Projects have been successfully implemented beneath businesses, railroad tracks, buildings, apartments, and even homes. Subgrade completion of GTR™ wells is possible in active facilities.

Competitive Pricing

The total cleanup costs with GTR™ are extremely competitive, especially when considering:

• No long term liabilities (and no uncertainty associated with it)
• Restoration of full property value
• No long term monitoring
• No disruption of operations during remediation
• Time value of money: remediation cycle of less than one year

When all costs are taken into account, thermal is often the most economical choice.

Applicable to a Wide Variety of Contaminants, Soil Types, and Configurations

Nearly all organic contaminants (and even a few inorganic contaminants) are suitable for GTR™ treatment. The technology works effectively in all soil types as conductive heat progresses quasi-homogeneously throughout the different lithologies.

Often the Most Sustainable Remediation Option

GTR™ is a very sustainable option compared to more traditional alternatives:

• After treatment, land usage is often unrestricted. GTR™ has attained residential closure standards in VOC and SVOC applications alike.
• Low energy consumption: energy efficient heater designs - combined with the use of "clean" natural gas or LPG - present an alternative to high amperage three phase electrical connections.
• No electrical or utility upgrades: no electrical upgrades are required at many project sites. When natural gas is unavailable, the GTR™ heaters can operate from LPG (propane) or diesel fuel sources.
