GROUNDWATER AND SOIL REMEDIATION AND GASOLINE TANK REMOVAL

Project description and scope

Envirofix was retained to remove two abandoned underground storage tanks (USTs)and remediate the associated contaminated soil and groundwater at a site of a former gasoline station in Brampton, ON, Canada. 

Project deliverables

In order to complete the project, EnviroFix provided the following services:

• Removal of USTs, pressure washing and offsite shipping of materials for recycling at a licensed facility
• Excavation of over 10,000m³ of impacted soil from the USTs’ bed and stockpiled in an area at the site; the impacted soil was made into bio-piles and petrophilic groups of bacteria were applied to the impacted soil

The bio-piles were equipped with a vapour collection system consisting of a network of piping connected to EnviroFix's mobile remediation unit. The vapour from the bio-piles was collected and treated prior to emission. The work was conducted under the EnviroFix ECA. The groundwater was pumped from a series of extraction wells and passed through an Envirofix mobile groundwater treatment system. 

This project was conducted on time and within the initial estimated budget.
