Thermally enhanced (steam injection) multi-phase extraction (MPE) remedial system at a former Industrial Site

Location
Toronto, ON
Key Services
  • Soil and Groundwater Remediation
  • Contaminated Site Remediation
  • Soil Vapour Extraction
  • Water Treatment
  • Pump and Treat Systems
Description
  • Milestone Environmental Contracting Inc. (Milestone) received a contract to undertake remedial work at a former industrial site. This site had been utilized for diverse industrial activities dating back to the 1930’s, resulting in soil and groundwater contamination primarily from petroleum hydrocarbons, including the presence of Light Non-Aqueous Phase Liquid (LNAPL). The remediation efforts encompassed designing, supplying, installing, commissioning and operating a thermally enhanced (steam injection) multi-phase extraction (MPE) remedial system at the Site.
Key Challenges

Key Challenges:

Logistical constraints

  • The site was situated within a heavy industrial area and included two industrial buildings with a significant portion of the contamination situated beneath one of them.

Concurrent Activities

  • Concurrent activities on the site posed potential risks to both schedule and safety, requiring careful coordination among multiple stakeholders.

Uptime

  • Maintaining system uptime and ensuring uninterrupted remedial operations.
Key Solutions

Logistical constraints

  • The use of an in-situ remedial approach, combined with careful integration of site-specific logistical constraints into the design, allowed remediation to proceed without disturbing the existing structures. This preserved the architectural and infrastructural integrity of the buildings, an outcome that would not have been achievable with conventional methods such as demolition and excavation.

Concurrent Activities

  • To address this, Milestone collaborated closely with the Owner and other Contractors, establishing clear time and space agreements. This proactive coordination minimized operational conflicts and maintained Health and Safety standards throughout the project.

Uptime

  • Thorough planning was conducted during the design phase, including robust contingency measures to mitigate downtime risks.
