Along the banks of the Yukon River, decades-old fuel contamination from a former refinery was slowly leaking into one of Canada’s most important freshwater systems. What began as a visible sheen on the river surface revealed a much larger problem beneath the ground: one involving multiple fuel types, sensitive habitat, and a long list of regulatory and community stakeholders.
North 60 Petro Ltd., the current site owner, faced an urgent challenge. They needed to stop the contamination from reaching the river while navigating a complex regulatory environment and working within a short fisheries window. PGL was retained to help chart a path forward.
PGL led detailed site investigations, risk assessments, and remediation planning to understand how the contaminants were moving through soil and groundwater toward the river. Working with engineers, biologists, and regulators, PGL helped design a remediation strategy that balanced effectiveness, constructability, and environmental protection.
PGL supervised foreshore excavation and restoration works, including installation of containment systems and treatment infrastructure to manage contaminated soil and water. Follow-up measures ensured longterm control of residual contamination and prevented future releases to the river.
Through careful coordination and risk-based decision-making, the project moved from ongoing environmental threat to active protection, which safeguarded the Yukon River while meeting the needs of regulators, the community, and the client.
