Montreal, Quebec, November 18, 2024 – ALTRA | SANEXEN has been honored with the coveted 2024 Brownie Award for Sustainable Remediation, showcasing their innovative approach to complex environmental challenges. The award-winning project, a collaboration with Vivenda and the Ministère de l'Environnement, de la Lutte contre les changements climatiques, de la Faune et des Parcs, transformed a former quarry in Montreal into a thriving residential development.
Overcoming Unprecedented Challenges
The project site presented a formidable challenge with its intricate soil contamination profile, featuring a hazardous mix of organic and inorganic compounds, including persistent petroleum hydrocarbons. ALTRA | SANEXEN's team of environmental experts rose to the occasion, devising a three-pronged remediation strategy: strategic excavation of contaminated soils to the groundwater table, cutting-edge in-situ treatment for petroleum hydrocarbon contamination, innovative risk assessment approach for metal-contaminated soils. This multifaceted solution not only addressed the site's complex contamination issues but also paved the way for sustainable urban development.
Redefining Brownfield Redevelopment
The approval of ALTRA | SANEXEN's remediation plan marked a turning point in brownfield redevelopment practices. It enabled the seamless construction of a four-story residential building with underground parking, all while the in-situ treatment continued – a testament to the efficiency and effectiveness of the company's approach.
