Phillipsburg, New Jersey: GTR with Soil Vapor Extraction

GEO used Gas Thermal Remediation in Phillipsburg, New Jersey, to address PCE and TCE in the subsurface. GTR supplied thermal conduction heating through 44 heater wells. The source lists a target temperature of 100°C and a heating period of 102 days.

Aboveground treatment equipment at the Phillipsburg, New Jersey project.

The extraction network included 12 deep dual-nested soil vapor extraction wells and five shallow soil vapor extraction wells. Extracted off-gas was treated with C3 Technology and activated carbon. The case study describes heating to depths of up to approximately 41 feet, with groundwater encountered at approximately 50 feet.

The reported removal rate for identified VOCs exceeded 98%, above the project's 75% removal goal. These results describe treatment of the defined soil volume.

GTR and TCH are complementary descriptions in this project: GTR identifies the fuel-fired heating system, while TCH describes how heat is transferred into the formation.
