 Background
For nearly two decades, this 111,000 m2 urban area had been used
for the unauthorized burial of wastes and served no productive
purpose. Although a property developer was considering this land as
a potential location for the largest soccer complex to ever be built
in Canada, the project had been deferred numerous times due to the
unknown volume of contaminated soil and cost of the remediation
work.
Solution
After undertaking a thorough investigation of the project and a
complementary characterization study, Biogenie proposed a global
remedial solution which included cost guarantees and met the new
regulatory requirements established by the Quebec Ministry of
Environment (MENV). This solution involved the excavation and ex
situ treatment of contaminated soil, management of close to 110,000
m3 of soil in order to prepare the area for the proposed investment
project, implementation of containment and mitigation measures,
backfilling with clean soil and development of an environmental
monitoring program.
Services
-
In-depth analysis of previous characterization studies
-
Complementary study to precisely assess the scope of the project
and requirements associated with the new regulations;
-
Detailed design and presentation of a remedial solution to the
many organizations and partners involved in the investment
project;
-
Assistance in the preparation of a presentation to the MENV,
which resulted in a $1,320,000 grant for the project as part of
the Revi-Sols (Phase II) program;
-
Management of close to 110,000 m3 of soil to optimize the reuse
of the material on site;
-
Excavation and off site treatment of close to 4,500 tons of
petroleum hydrocarbon-contaminated soil;
-
Implementation of containment and mitigation measures:
construction of a collection trench to control groundwater
inflow, installation of a surface drainage system, installation
of a biogas venting system as a preventive measure, backfilling
of a one-meter deep layer of clean soil;
-
Development of a detailed environmental monitoring program.
