Former Fuel Dispensing Facility in Toronto

Case Study - PHCs



Overview

At a former fuel dispensing facility in Toronto, historical leaks from a series of underground storage tanks and pipes resulted in the development of a groundwater plume over an area of approximately 1,000 m . Excavation was deemed to be technically challenging and cost prohibitive. Compounds of concern within the soil included:

  • BTEX (concentration > 300 μg/g)
  • F1 & F2 (concentration > 2,800 μg/g)
  • F3 & F4 (concentration > 1,000 μg/g)

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

The Vertex Approach

  • In-situ chemical oxidation
  • Multiple applications using direct push
  • Injection of chemical oxidant
    • > 25,600 kg of RegenOx
  • Injections completed using:
    • vertical direct push points

Outcome

  • Over 250,000 L of oxidant solution delivered to impacted areas
  • Greater than 90% of remediated to residential standards
  • No surface infrastructure required
  • RegenOx solution effectively distributed throughout impacts areas as confirmed by tracer and geochemical testing
  • Record of Site Condition Obtained
