A Global Leader in Thermal Remediation

Remediation at the Terminal One Tank Farm in San Francisco Bay

This project was in the beautiful San Francisco Bay adjacent to a marina. The City of Richmond’s 14-acre site, known as the former Terminal One, was operated as a shipping and bulk storage terminal.

A small portion (~1,400 ft2) of the target treatment zone (TTZ) was underneath a 90,000 ft2 warehouse built on concrete pilings. The warehouse was not demolished until after the remediation part was complete, so TerraTherm installed wells inside the warehouse to treat the soil below the building.

  • COCs: PCE, TCE, cis-1,2 DCE, and vinyl chloride
  • Geology: Bay mud and tight clay
  • 138 heater wells were laid out on a 12-feet spacing hexagonal grid. Granular activated carbon and potassium permanganate for off-gas treatment was used to treat the vapor stream.

Thermal Treatment of CVOCs in Overburden Bedrock

Thermal Conduction Heating (TCH) was selected to treat CVOCs from ground surface down into the top of two feet of weathered bedrock. The target treatment zone (TTZ) was located right next to a storm sewer which resulted in a gentle heating strategy around the sewer line.

  • Site specific contaminant of concerns (COCs) were identified as primarily tetrachloroethylene (PCE), trichloroethylene (TCE)
  • The primary objective of in situ thermal remediation (ISTR) was to treat Site COCs in the treatment zone to a concentration equal to or less than 10% of the New Jersey Residential Direct Contact Soil Remediation Standards (RDCSRS).

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).

A total of 51 heater wells were used to heat the interval from 10-80 ft bgs, while 8 steam injection wells supplied heat below the TTZ from 80 to approximately 100 ft bgs. A total of 3,620,000 lbs of steam was injected. Several existing well locations were reused as temperature or pressure monitoring points to reduce drilling costs.

  • 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
