Covering roughly 46 hectares, the PEPSC (Parc d'entreprises de la Pointe-Saint-Charles) site is located in the Sud-Ouest Borough, near the North Shore of the St. Lawrence River, between the Victoria Bridge and access roads for the Bonaventure Expressway. The project was developed to decontaminate groundwater (petroleum hydrocarbons, PCBs, PAHs, metals, and ammonia nitrogen). Unigesco was tasked with building this groundwater treatment plant.
