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.
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.
