Overview
At a trailer park in Eastern Ontario, two heating oil tanks released heating oil into the underlying unconsolidated and fractured media. Following excavation of the unconsolidated material, an in-situ chemical oxidation program was completed to address the petroleum hydrocarbon plume and associated free phase within the fracture rock.
- BTEX (concentration of 1,920 μg/L)
- F1 to F4 (concentration of 59,200 μg/L)
- Free phase up to 3 cm thick
Scope of Work
- Acquired all relevant permits to complete the remediation program
- Designed and optimized an in- program to maximize treatment efficiencies
- Implemented a program that minimized capital expenditures and infrastructure
