Approximately 4,000 tons of soil impacted with hydraulic oil and diesel fuel at a former manufacturing facility in Georgetown, Ontario were effectively treated ex situ with Terramend® reagent.

Hydraulic oil, diesel fuel, TPH
Approximately 4,000 tons of impacted soil were excavated and placed in a remediation cell. Terramend® was applied to the cell using a site-specific aerobic protocol with the goal of achieving the remedial standard of 1,000 mg/kg of heavy oils and 100 mg/kg for gas/diesel in all sampling zones.
Active treatment of the soil occurred within the treatment cell for a period of approximately 12 months, with a 5-month inactive period. During this period, soil hydrocarbon concentrations were reduced by approximately 99%. Following treatment, the mean concentration of the gas/diesel rang hydrocarbons was 3 mg/kg, while the mean concentration of heavy oil hydrocarbons was 67 mg/kg. It should be noted that due to cost constraints, treatment proceeded more slowly that otherwise possible, resulting in lower remedial costs.
Terramend® Reagent was used to remediate approximately 10,500 cubic yards of soil impacted by diesel petroleum hydrocarbon at levels ranging from 500 mg/kg to 3,000 mg/kg.
Terramend® was used to treat soil impacted with 40,000 liters of crude oil along a remote stretch of highway north of Perth, Australia. The remediated soil was then used for gravel pit rehabilitation.
Soils impacted with Polycyclic Aromatic Hydrocarbon (PAH) and Pentachlorophenol were treated in situ and ex situ in an independent study for the US EPA Superfund Innovative Technology Evaluation (SITE) program. Terramend® reagent supported removal of all target compounds in soil at the Domtar Wood Preserving site.
