Founded 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. Learn
