Gas Station Remediation Southern Alberta: ISCO & SVE Treatment

A closure-based in-situ chemical oxidation (ISCO) remediation was conducted at a former gas station in Southern Alberta to address BTEX, F1, F2, and PAH contamination in 6,630 m³ of impacted soil, bedrock, and groundwater, including off-site impacts beneath residential properties. Due to infrastructure constraints and vapour risks, a Remediation Train® approach was implemented, starting with a soil vapour extraction (SVE) and air sparge system, followed by a ISCO program with a 3-meter injection radius. Nested injection wells targeted various depth intervals, with careful scheduling around residential activity. Over 45 days, 1.6 million liters of 10% EHP (enhanced hydrogen peroxide) was injected using TRIUM’s ChemOx® process, achieving daily blend volumes of >35,000 L. The treatment successfully met regulatory groundwater quality guidelines, managed vapour risks, and was recognized as an industry-leading process by consultants, with no negative impact on the community.

Pipeline Release Remediation in Central Alberta | ISCO & Permeable Trench

A pipeline release at an active multi-well pad in Central Alberta required remediation due to BTEX, F1, F2, and PAH contamination in 2,000 m³ of impacted soil and groundwater, with remediation timeframes limited by site conditions. A staged risk-based in-situ chemical oxidation (ISCO) approach was implemented with a 3-meter injection radius, involving the installation of 52 injection wells and five permeable reaction trenches to facilitate groundwater extraction and oxidant circulation. A total of 17,500 liters of 12% EHP (enhanced hydrogen peroxide) was injected using TRIUM’s ChemOx® process, with injections timed during frost-cap months to maintain pressure. Results show a well-defined and shrinking plume, significant source area concentration reductions, and an approximate 90% decrease in PHC and PAH concentrations since project inception.
