Terramend® reagent was selected for the in situ treatment of 14,000 tons of BEHP impacted soil at a former plastics manufacturing facility.
Former plastics manufacturing facility; Confidential client
New Jersey, USA
Bis (2-ethylhexyl) phthalate (BEHP)
The remedial goal of 210 mg/kg for BEHP had to be achieved in the upper two feet of all impacted areas of the site and some regions of the site also required treatment of PAHs. Over 4 acres of the 12-acre site required treatment, and some treatment activities had to be coordinated with tidal fluctuations, given that the water table was very close to the surface and heavily influenced by the tide. Terramend was applied in situ using a site-specific aerobic protocol.
The mean concentration of BEHP was reduced from 1,250 mg/kg to less than 150 mg/kg after approximately 10 months of active treatment, surpassing the remedial goal of 210 mg/kg. Elevated PAH concentrations were also reduced to below the NJ Department of Environmental Protection criteria.
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® was used to treat 150 tons of sediment dredged from PAH impacted regions of Hamilton Harbor.
