Trans Mountain Pipeline Site KP387 Bioremediation

During a reactivation dig in 2021, historical petroleum hydrocarbon contamination was discovered at a site on the Trans Mountain pipeline right of way (RoW) located 8 km west of Jasper and next to the Miette River. Further assessment delineated contamination along the right of way and adjacent wetland, fen and marsh. The Remedial Action Plan recommends in-situ bioremediation as the best option to reduce contaminants to acceptable levels in both soil and groundwater, while minimizing further impacts to the area. Bioremediation involves using microbes to naturally degrade hydrocarbons, turning them into H2O and CO2. The proposed bioremediation method involves adding microbes to the site that resemble the local microbial populations.

Trans Mountain proposes to begin the microbial treatment in May 2024, and possibly re-apply in October 2024. The treatment will be applied by digging shallow hand auger holes to 1.0 – 2.5 m below surface and injecting the microbes into the subsurface. Post injection of the microbial treatment, site monitoring of soil and groundwater will occur for two years to verify performance of the microbial treatment.
