Remediation & Reclamation

We are a leading Canadian remediation contractor specializing in the segregation, handling, and treatment of contaminated soils, water and hazardous wastes.

What is the difference between remediation and reclamation?

Remediation is the process of removing contaminants from soil and water that may impact the ecosystem of a site. Activities during this phase may include soil removal or treatment, water treatment, tank removal and facility decommissioning.  Site remediation activities required depends on the previous uses of the site.
Reclamation is the process of returning a site to its pre-disturbed state. Activities can include site contouring, revegetation, creation of micro-sites to support habitat development and final reclamation reporting.

Five Stages of a Successful Wellsite Reclamation

To successfully remediate and reclaim a wellsite, there are five stages that a site must go through. Each stage has certain requirements to be met and ways Tervita can support you.

Our operators are trained and experienced in the identification and segregation of contaminated soils and our specialized earthworks equipment allows for more accurate separation of soils. We have extensive experience in all aspects of the excavation, transportation, and treatment or disposal of contaminated soils. Our teams of trained professional project managers, site supervisors, and equipment operators have successfully completed thousands of such projects. This includes planning activities such as utility locates, geotechnical evaluation and communications with local governing authorities. We analyze each remediation challenge and offer a variety of strategies for eliminating the contamination. We have the capacity, experience and equipment inventory to direct large and complex remedial projects involving the excavation of large soil volumes.  

  • Soil excavation, transport and disposal
  • Underground storage tank removal
  • Water management and disposal
  • Supply and installation of remediation systems
  • Flare pit, well site and pipeline remediation
  • Bioremediation and soil treatment
  • Landfill decommissioning

We are also experienced with a variety of in situ environmental remediation strategies, using equipment that enables us to address soil contamination at its source. With solutions like chemical injection and vapour extraction, we inhibit the migration of contaminants and speed up their natural decomposition. We offer an extensive inventory of specialized environmental remediation equipment & installation services.

Soil Excavation, Transportation, Treatment & Disposal

Tervita has extensive experience in all aspects of the excavation, transportation, and treatment or disposal of contaminated soils. Our teams of trained professional project managers, site supervisors, and equipment operators have completed thousands of such projects. This includes planning activities such as utility locates, geotechnical evaluation and communications with local governing authorities.

Sludge & Soil Stabilization

To meet the demands of clients, Tervita has experimented and researched a variety of reagents to stabilize soils and sludge cost-effectively. Reagents and the stabilization process can be costly and as a result demonstration trials become an important preliminary step to determine the most suitable stabilization process and the optimal reagent concentrations to ensure effective, long term stabilization.

Storage Tank Decommissioning

Tervita has successfully decommissioned hundreds of above and below ground storage tanks ranging in size from 500 gallons to 50 million gallons. Tervita also provides complete services including removal & disposal/recycling of residual tank waste, explosive vapour monitoring equipment, excavation, removal, cleaning, and disposal of the tanks, selective excavation and sampling of potentially contaminated soils, transportation and disposal of contaminated soils, return excavation to existing surroundings, and installation of replacement tank if required.

We own and operate a large equipment fleet and have developed significant infrastructure to serve our customers in the most environmentally friendly, safe and economically viable ways available. All personnel who operate this equipment are employees of Tervita who have gone under extensive operator health and safety training. Tervita’s specialized remediation equipment includes:

  • Soil Screeners & Conveyors
  • Multi-Phase & Soil Vapour Extraction Systems
  • Trommel Screener
  • Off-Gas Treatment Systems
  • Scarab Mixers
  • Activated Carbon Filtration Systems
  • Air Sparging Systems
  • Suspended Solids Reduction Filters
  • Water Treatment Systems Excavators

Bioremediation

We have constructed many and varied types and sizes of bioremediation cells as large as 200,000 tonnes to meet the economic and liability needs of our customers. These include:

  • Above or below ground cell construction
  • Leachate collections system
  • Powered ventilation, passive ventilation or no-ventilation cells
  • Earthen or concrete wall construction
  • Use of various liner types i.e.: HDPE, PVC, and RPE

Mine Rehabilitation

Neutralizing and relocating large volumes of tailings and waste rock material are challenging aspects of mine site rehabilitation. We are an experienced leader in large mine site rehabilitation and have earned the distinction of successfully installing North America's largest geosynthetic clay liner tailings capping system. Our expertise also extends to dredging services for recovering lakebed sediments and water treatment plant design, construction and operation. 

Our ability to integrate our in-house capabilities across the entire spectrum of mining rehabilitation requirements offers customers a convenient, cost-effective, single source for mining rehabilitation.

Asset Retirement and Compliance

Oil and gas producing fields and their associated facilities share a common reality – they have finite life spans. As the WCSB and other basins around the world mature, innovative thinking is required to ensure the industry grows and ages in a manner that is both responsible and sustainable.

Tervita has developed a fully integrated solution providing safe, cost-effective, and efficient management of the entire end-of-life process. Our process restores the land to a reclaimed state, meeting or exceeding regulatory standards. Delivering streamlined solutions that expedite the return of lands to public and/or alternative use is the foundation of this integrated service.

  • Asset retirement services include:
  • Downhole and surface well suspension
  • Integrated well abandonment
  • Pipeline integrity and compliance
  • Facility decommissioning and demolition
  • Full cycle waste management
  • Site remediation and reclamation
  • Regulatory compliance data management solutions
