Remediation of PCB-Impacted soil at Industrial Facility in Guelph
Soil & Groundwater Remediation, PCB Clean-up
Tri-Phase was retained to remediate the property with a 100,000 square foot plant on 100 acres, which had been heavily contaminated with PCBs. The plant was used to produce transformers and the main objective was to maintain contamination on-site and ensure compliance with regulatory authorities.
The work included the excavation, solidification and disposal of over 30,000 tones of PCB-contaminated soil/sludge as well as the decommissioning of the old oil interceptor pond and construction of a new two-stage oil interceptor/ retention pond. Hydrocarbon and PCB-contaminated groundwater was controlled and treated on-site (over 8 million liters). Other work included the clean-up and decontamination of PCB-contaminated tankers using confined space entry teams, sewer flushing and lining as well as power washing.
A major component of the work also included the decommissioning of the existing groundwater recovery and treatment plant and design/build of the new treatment plant with a capacity of 500,000 liters/day.
