Trailer Park in Eastern Ontario

Case Study - PHCs



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
