Project Summary

The impacted soil was contaminated with petroleum hydrocarbons resulting from a former on-site underground storage tank (UST). The targeted remediation goals were the Saskatchewan Environment Criteria for BTEX and PHC fractions in a fine-grained surface soil using an agricultural land use. A total of approximately 1,100 m³ was transported to a designated treatment pad where bioremediation was initiated by utilization of our dual-drive Allu bucket attachment. The remaining bioremediation process was completed within a windrow turner.

Results and Advantages

• Achieved successful remediation for Benzene, Toluene, Ethyl-Benzene, Xylene and F1 (C₆-₁₀) petroleum hydrocarbons (results were <0.04 ppm, <0.10 ppm, <0.10 ppm, <0.10 ppm, and a range of 20 to 46 ppm respectively).
• Treated material was subsequently used as daily cover at the landfill.

Duration and Cost

• Project completed in 2 months.
• Project Cost:
  ± $57,000.00 (on budget)
