Residential UST Spill Remediation in North Vancouver BC: In-Situ Chemical Oxidation Success

An in-situ chemical oxidation (ISCO) remediation was conducted at a residential property in North Vancouver to address petroleum hydrocarbons (LEPH), phenanthrene, and pyrene contamination in 200 m³ of impacted soil and groundwater following a heating oil UST leak that migrated under the building foundation, causing vapour intrusion and free product in property sumps. A 2.5-meter injection radius was used for targeted treatments within the basement and exterior property foundation, utilizing directional injections and drive-points to reach both saturated and unsaturated zones. TRIUM leveraged the property’s sump system to artificially raise the groundwater level, creating a fully saturated treatment zone. Over seven days, 24 basement injections and 3 exterior injections delivered 20,104 litres of sodium persulfate, blended using TRIUM’s TriOx process with specialized activation products. The treatment successfully met regulatory soil, groundwater, and vapour guidelines, required only six weeks for completion, and allowed the property owner to safely return home with minimal disturbance.

Pipeline Release Remediation in Central Alberta: A Risk-Based ISCO Case Study

A pipeline release site in Central Alberta faced residual petroleum hydrocarbon contamination (BTEX, F1, F2) that could not be fully treated with a multi-phase extraction system. Due to site lithology, a risk-based in-situ chemical oxidation (ISCO) approach was implemented with a 1.5 to 2.5 meter injection radius, installing 12 injection wells and injecting 6,500 liters of 12% EHP (enhanced hydrogen peroxide) followed by 3,700 liters of 15% sodium persulfate using TRIUM’s ChemOx® process. The treatment successfully removed all residual NAPL, fully remediated the plume area, and exceeded performance expectations within a short timeframe.
