Thermal Remediation Services, Inc. (TRS) successfully completed the remediation of subsurface trichloroethene contamination in a mixed-phase environment on a time-based, fast-track, guaranteed basis. By utilizing TRS’ signature Electrical Resistive Heating (ERH) technology complimented by vapor recovery, TRS was able to overcome significant challenges that included: A low permeability soil/clay matrix. A tight time schedule for project completion. Contamination at varying depths extending below the groundwater level. Remediation goals magnitudes lower than original contamination levels. Figure 1 shows the average TCE concentration in soil before and after ERH-based remediation.
