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.
Industrial Site - Former underground storage tank at a transportation hub
Northern California
Diesel petroleum hydrocarbon (TPH-d)
Terramend® reagent was applied to excavated TPH-impacted soil in a soil remediation cell. The remediation cell was irrigated to achieve the desired water holding capacity level to create optimal conditions for aerobic bioremediation of TPH compounds in soil.
TPH-d concentration was monitored biweekly using samples collected in 10 sections within the remediation cell. The remedial target of 400 mg/kg was achieved in all sampled sections after 120 days of remedial activity.
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.
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.
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.
Terramend® was used to treat 150 tons of sediment dredged from PAH impacted regions of Hamilton Harbor.
Terramend® reagent was selected for the in situ treatment of 14,000 tons of BEHP impacted soil at a former plastics manufacturing facility.
