The project consisted of a request made by the Société des parcs Sorel-Tracy, the MRC Bas-Richelieu, the city of Sorel-Tracy and the riverside contractors.

Dredging and Basin
Cleaning Project

Shell Refinery in Montreal

For this dredging project, 60,000 m3 of C-D and D+ contaminated sediments were treated in the vicinity of the Shell refinery in Montreal. The Gersol team also undertook the cleaning of two tanker anchorage basins as well as the installation of large basins to receive the contaminated sediments. These were dewatered and recycled according to their degree of contamination. Finally, Gersol carried out the transportation and disposal of the contaminated sediments at the accredited sites.
