Found in 1992, the Envirosoil facility in Bedford, Nova Scotia was designed and constructed to provide a solution for the treatment and disposal of hydrocarbon impacted soil and was the first commercial soil treatment facility in Atlantic Canada. The demand for soil remediation came into being as a result of leaking oil tanks and subsequent regulations imposed in late 1988 requiring operators to remove the tanks and make reparations. The regulations, enacted by the Departments of Environment for each of the Atlantic Provinces, focused on the contamination of soil and subsequently the underground water supply from petroleum hydrocarbons.
Initially, contractors were hauling petroleum hydrocarbon impacted soils to landfills but this proved unsatisfactory in part because the landfills were not appropriate disposal and not all jurisdictions had landfills available.
Initially the Envirosoil facility was approved for the use of biological treatment methods to treat impacted soils but by the end of 1994 this technology proved to be inadequate for the desired goals of the company. Envirosoil abandoned biological treatment and procured a Low Temperature Thermal Desorption (LTTD) unit in 1995 from Astec Industries located in Tennessee. At that time, Astec as well as several other major asphalt plant manufacturers had been designing and building “soil treatment plants” for over 10 years in the United States. They had become popular as a remediation technology due to the quality, certainty, and timeliness of the soil treatment achieved.
Although, the Envirosoil facility was originally designed and constructed to address fuel oil spills from residential and commercial facilities, the evolution of the entire environmental and remediation industry has proven to expand the focus of the facility. One of the largest drivers behind the requirement to treat impacted soil is the remediation that is often required when properties are being sold. New owners and mortgage companies are often less likely to buy a contaminated site. The addition of treatment for Bunker, PAH and PERC have permitted the facility to provide more solutions to the remediation.
With the growth of the Offshore Oil & Gas Industry in Atlantic Canada has materialized another opportunity for Envirosoil to provide a solution for the treatment and disposal of Oil Based Mud Cuttings for offshore drilling activities.
The combined results of brownfield development, oil & gas exploration and residential and commercial fuel spill remediation have resulted in an ever increasing demand for an effective soil treatment facility in Atlantic Canada and Envirosoil has the facility to provide the solutions required.
