A Global Leader in Thermal Remediation

SEE/TCH Remediation at a Former Manufacturing Site

The site consisted of two adjoining parking lots at different elevations, separated by a 8-foot retainage wall. The source zone was located below portions of both lots. In order to heat the lower portion and reduce the amount of groundwater entering the heated zone, TCH was combined with Steam Enhanced Extraction (SEE).

  • Volume: 15,392 cy
  • Contaminants of concern: CVOCs (primarily TCE and PCE)
  • Over 22,000 lbs of contaminated mass was removed

ERH Remediation of Active Gas Station

Electrical Resistance Heating (ERH) was selected to address both soil and groundwater impact within the source area. Underlying geologic units included sandy silt, fill, dense till, and a deep gravel outwash. Due to their varying electrical conductivities, different voltages and currents were applied to the distinct soil layers using a system of stacked electrodes.

  • Electrodes were placed across the steeply sloping 12,800 ft2 treatment area
  • Heating extended to a maximum depth of 52 ft below ground surface
  • 19,000 lbs of contaminated mass removed

TCH Treatment of Creosote and SVOCs to 350°C at former Wood Treatment Facility

This is the largest high temperature ISTR project ever undertaken at a wood treatment site. The only alternative deemed capable of achieving the unrestricted land use goal was soil excavation followed by off-site incineration. The thermal solution was approximately 40% lower cost than the excavation/incineration alternative for this F-listed waste.

  • 785 thermal wells, including 654 heater-only and 131 heater-vacuum wells at 7 ft spacing at the site
  • Contaminants: Petrachlorophenol, PAHs, creosote, (wood) and dioxins
  • The target temperature to achieve destruction and removal of all COCs including dioxins was 335°C.

Dioxin Treatment at Da Nang Airport – Phase 2

Soil and Sediment contaminated with dioxins due to the disposal of Agent Orange at the former military airfield in Da Nang , was excavated and loaded into a specially designed and constructed pile 6m tall and roughly the size of a football field.

  • Heaters: 1,254
  • Volume:
    • Phase 1 – 43,348 m3
    • Phase 2 – 49,071 m3
  • Goal: 150 ppt for 2,3,7,8-TEQ
  • Results: 8.9 ppt for 2,3,7,8-TEQ
  • TerraTherm received the EBJ 2018 Business Achievement Award for Project Merit in Remediation.
