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.

Wellsite Sump Remediation in Barrhead, AB: In-Situ Chemical Oxidation Success

An in-situ chemical oxidation (ISCO) remediation was conducted at a former wellsite sump in Barrhead, Alberta to address BTEX, F1, and F2 contamination in 645 m³ of impacted soil and 3,000 m³ of impacted groundwater. Due to shallow groundwater and a saturated silty sand lithology, excavation was limited, requiring targeted in-situ treatment. A 0.75-meter injection radius was used for soil treatment via 40 injection points, delivering 28,000 liters of 10-15% MFR (modified Fenton’s reagent) over five days, while groundwater remediation involved 13 wells, injecting 60,000 liters over two events spanning 20 days. Using TRIUM’s TriOx process, the project achieved a >90% contaminant reduction, meeting regulatory guidelines within a short treatment timeframe.
