Drilling Sump Remediation in Central Alberta | Ex-Situ Chemical Oxidation

Former drilling waste disposal area under active remediation and with limited site access. Contaminants in the soil included BTEX, F1, and F2. A total of >10,000 m3 of low to moderate PHC impacted mineral soil, up to 7,000 ppm TPH.

EXCO process conducted on aliquots of up to 750 m3.  Daily production of 300 m3. A specialized mulcher was used for the project in order to ensure the greatest contact between the oxidant and the impacted soils.

Mineral soils had a total of 500,000 Lof 25% - 50% EHP (enhanced hydrogen peroxide) applied.

• Treatment of soils was completed in less than 3 months
• >90% of mineral soil was remediated to below applicable guidelines
• Mineral soils were backfilled and organic soils were left in place for further soil management
