Electrical Resistance Heating with Steam Enhanced Extraction at a Superfund Site

TerraTherm deployed both Electrical Resistance Heating (ERH) and Steam Enhanced Extraction (SEE) to treat the heterogeneous subsurface lithology where some depth intervals were too tight for SEE and groundwater flow in other intervals too high for ERH. Once the source remediation was complete, clean water was pulled through the downgradient plume to enhance the effectiveness of the bioremediation approach.

All 100 soil confirmation samples collected from various locations and depths within the treatment zone met the thermal remediation goals (<10 mg/kg PCE) after 150 days of heating. Total contaminant mass removed from the site was 7,800 lbs (three times the original mass estimate).

Thermal Treatment of Deep Bedrock

For the thermal design, every heater boring was equipped with a co-located soil vapor extraction well, allowing for the best pneumatic connection to the bedrock fracture system. The concentration of TCE in these vapor streams from individual wells was used to gauge remedial completeness. Our Tier-One containerized treatment system was utilized to treat the contaminants.

TCE vapor concentrations at heater locations were decreased 99.98% during operation, while the concentrations at nested soil vapor probes located at the midpoint between heater borings decreased 99.9%.

Remediation of Coal Tar in a Manufactured Gas Plant Gasholder

An abandoned gasholder contained approximately 2,200 cy of soil and debris contaminated with coal tar. We utilized our high temperature TCH approach to perform a multi-level in situ heating approach for coal tar remediation. To our knowledge, this is the first site where a multi-level in situ heating approach was ever applied.

A total of approximately 140,000 lbs of mass was removed from the relatively small gasholder, and as a result of the material removal, the soil in the holder subsided. By eliminating DNAPL within the holder and reducing concentrations of VOCs, SVOCs, and TPH below MCP upper concentration limits so that residual risk is minimized. All remedial goals were met.

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 of the target treatment zone  was underneath a 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.

Following treatment, soil concentrations of PCE were reduced from 2,700 mg/kg to 0.012 mg/kg which is more than 99.99%. Similar effectiveness was documented for TCE, cis-1,2 DCE, and vinyl chloride. All goals were met on time and within budget.
