Jasper National Park – Hydrocarbon In-Situ Microbial Remediation

Hydrocarbon impacts from a historical pipeline release extended across approximately 9,000 m² within a wetland adjacent to a river, requiring a remediation approach that minimized disturbance while meeting regulatory and stakeholder expectations.

Alta Tech developed a low-impact remediation strategy supported by detailed site investigation and stakeholder engagement.

Work included

• Development of the conceptual site model using historical and field data
• Coordination with Parks Canada and Indigenous stakeholders
• Design and implementation of in-situ microbial treatment
• Injection of targeted microbial strains using controlled delivery systemsOngoing monitoring to assess treatment performance

Approximately 70% of the site has been remediated to applicable guidelines, with significant reductions in hydrocarbon concentrations. The selected approach minimized environmental disturbance and achieved an estimated cost savings of ~$6 million compared to conventional excavation.
