Terramend® was used to treat 150 tons of sediment dredged from PAH impacted regions of Hamilton Harbor.
Hamilton Harbor, Hamilton, Ontario, Canada
PAHs
Sediments in the harbor were impacted with a variety of contaminants including residue from coal coking operations for the steel manufacturing industry, with PAH concentrations exceeding 1,400 mg/kg in regions of the harbor. Terramend was applied to 150 tons of dredged sediment in an engineered bioremediation cell using site-specific technology.
Following the application of Terramend, total PAH concentrations were reduced from 1,139 mg/kg to 110 mg/kg, which comprises a reduction level of 90%. With the exception of benzo(a)pyrene, all regulated PAH isomers were below the guidelines established by the Canadian Council of Ministers of the Environment (CCME) after 245 days of treatment. Benzo(a)pyrene was reduced below its target after 312 days.
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® 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® reagent was selected for the in situ treatment of 14,000 tons of BEHP impacted soil at a former plastics manufacturing facility.
