TerraTherm Recognized with EBJ Business Achievement Award
April 5, 2023
Environmental Business Journal® (EBJ) has honored TerraTherm with a Business Achievement Award for project merit. Awards were given for projects that completed or passed a significant milestone in 2022 and were noted for innovation, unique solution, or partnership (in water, remediation, NRM, EC, or other areas) and TerraThem was selected for a remediation project.
“In a rather tumultuous year of economic ups & downs in 2022, a number of companies set themselves apart with performance, transactions or projects that merit special consideration,” said Grant Ferrier, editor of Environmental Business Journal and chair of the selection committee.
TerraTherm was contracted to remove free-phase non-aqueous phase liquid (NAPL) and reduce organic benzene, toluene, ethylbenzene, and xylene (BTEX) and naphthalene to below the industrial/commercial remediation objectives to the extent practicable at a former manufactured gas plant (MGP) site.
TerraTherm’s approach combined thermal conduction heating (TCH) with multi-phase extraction (MPE). The project was implemented in two phases, first treating a 10,789 cubic yard volume around a former MGP gas holder and then continuing treatment in the adjacent 24,676 cubic yard volume that encompassed the former MGP infrastructure. The second phase of treatment was successfully implemented around a large 8-ft diameter active sewer line that ran through the treatment zone. Subsurface temperatures were monitored around the sewer throughout operations. Power input to the heaters was adjusted during treatment as needed to ensure safe temperature limits were not exceeded and the sewer was not damaged.
TerraTherm heated and treated the site to achieve diminishing returns, and removed an estimated 41,000 lbs. of contaminant mass from the subsurface, with an estimated additional 48,957 to 125,171 lbs. of contaminant mass destroyed in situ. Final project reporting was completed in 2022.
The 2022 EBJ awards were presented at the EBJ Business Achievement Awards banquet at Environmental Industry Summit XXI on March 22-23, 2023 in San Diego.
