Former flare pit area overlying shallow fractured bedrock. Condensate (BTEX) contamination dissolved in groundwater covering 21,000 m2.
Conduct detailed geological/hydrogeological investigation to identify fracture pathways and contaminate transport.
In-situ chemical oxidation (ISCO) program based on 15-meter injection radius of influence. Establish health and safety protocol and site logistics for handling oxidizer.
Installed 90 injection wells and injected over 100,000 litres of blended 17% EHP (enhanced hydrogen peroxide) oxidant. Blending is site specific following TRIUM’s ChemOx® process.
AISCT® revolutionizes site characterization with rapid, 20-minute soil and water analysis. This portable technology reduces lab dependence, enhances decision-making with real-time results, and ensures accurate volume estimations. It streamlines remediation, minimizes landfilling, and boosts confidence in project outcomes.
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 litres of 12% EHP (enhanced hydrogen peroxide) followed by 3,700 litres 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.
