Remedial Construction:
This project involved implementing soil mixing activities as part of a remedial action at the Goodfish Lake Former Municipal Waste Water Treatment Lagoon (the Lagoon) site in Goodfish Lake, Alberta. The intent of the in situ soil mixing (ISSM) operations was to treat the chlorinated solvents in the area of the Lagoon using in situ chemical reduction with granular zero valent iron (ZVI) delivered via soil mixing.

Geo-Solutions Inc. was subcontracted by Quantum Remediation to perform soil mixing activities at the site. For the construction effort, Geo-Solutions provided specialty equipment and materials including the soil mixing drill rig with a 2.4 meter (8 foot) diameter mixing tool, grout mixing plant, special in situ sampler, and all of the required bentonite materials. Geo-Solutions was also responsible for quality control of the work and the operation of key specialty equipment.

The area targeted for remediation is approximately 1,180 square meters (m2). The treatment zone extended to a maximum depth of 8 meters. The resulting treated volume was approximately 7,500 cubic meters.
