GTR™ is a system that is also used for onsite soil treatment, when the soil is treated on site after excavation (no transportation off site).

In Situ Thermal Conductive Heating using Gas Thermal Remediation (GTR™) was specifically developed to be the most flexible ISTR platform. Period.

GEO’s proprietary Electrical Resistance Heating (ERH) Technology is an intensive in situ environmental remediation method that uses the flow of alternating current electricity to heat soil and groundwater and vaporize contaminants. Alternating electric current is passed through a targeted soil volume between subsurface electrode elements. Operating voltages can be varied to adapt for different lithologies and dynamic resistive properties of many soil types.  The resistance to electrical flow that exists in the soil causes the formation of heat; resulting in an increase in temperature until the boiling point of water at depth is reached. After reaching this temperature, further energy input causes a phase change, forming steam and removing volatile contaminants. ERH – like TCH and SEE heating techniques – is typically cost effective when used for treating contaminant source areas.

Steam Enhanced Extraction ("SEE") has proven a successful In Situ Thermal Treatment method at multiple projects. The injection of steam heats the soil and groundwater surrounding the injection well. The steam front transfers the latent heat of condensation from the steam to the adjacent soil and groundwater, until temperatures are reached to sustain steam throughout the entire treatment zone.

Batch Pile Treatment is one of the most commonly applied methods of Ex Situ Thermal Desorption for the remediation of soils.  When soil is heated, the organic contaminants extracted from the soil pile or are destroyed in place.

Containerized thermal desorption systems for remediation of contaminated soils, sludge, sediments & assorted media. GEO designs, constructs and operates or leases its patented containerized thermal desorption (“CTD”) systems for onsite remediation of contaminated media, including soils, sludge, sediments and mixed waste streams. The CTD systems were designed for crude oil recovery from soils and sludge. The capacity of each container is 80 m3. The units are operated in cycles of 25 or 50 days.

C3 Technology is the pinnacle of vapor treatment effectiveness for the most demanding environmental remediation projects. C3 Technology harnesses a combination of compression, cooling  and condensation processes to recover all volatile organic compounds (VOCs) from the off-gas vapor stream of soil vapor extraction (SVE) or dual phase extraction (DPE) systems. VOC vapors are condensed by the system and recovered as a non-aqueous phase liquid (NAPL) that can be disposed of offsite or recycled. Generally, greater than 99.99% of VOCs are recovered from the vapor stream. Complex mixtures of chlorinated ethenes, ethanes and petroleum hydrocarbons are regularly processed by C3 Technology, even at extremely high influent concentrations.

GEO’s Cooling-Condensation vapor treatment systems provide enhanced recovery of volatile organic compounds.  The C2 Technology upstream conditioning systems control humidity and temperature while also removing organic compounds from the vapor stream ahead of final adsorption media used for final vapor treatment.  By condensing a portion of VOCs from the vapor stream, the loading of contaminants on the downstream adsorption media is reduced, thus extending the useful life of the adsorption media. Controlling for a constant vapor temperature further enhances the efficacy of common off-gas treatment media, such as vapor phase granular activated carbon.
