Contaminated Soil Remediation
Earth, Unsalted.
TERRAVOLT delivers expert soil remediation technology to our partners in Oil & Gas, Brownfield and Saline Agriculture sites across Canada. From salts and hydrocarbons to heavy metals, we return contaminated land to its natural state.
What We Do
Specialized Remediation for Oil & Gas Contaminants
TERRAVOLT's patented* electrokinetic stack is built to handle multiple contaminants: Cl, PHC, Heavy Metals. We partner with service providers and design site-specific strategies that address the contaminants, soil type, and local site conditions to achieve full regulatory closure.
Salt Remediation: Oil & Gas, Saline Agriculture
TERRAVOLT's patented* electrokinetic technology excels at removing salts (NaCl) from multiple soil types: sand, silt, and clay. The innovation is our multi-cell wafers (EK stacks) and our advanced, contaminant-specific electrolytes.
- Electrical conductivity reduction
- Sodium adsorption ratio correction
- Soil amendment application
- Vegetation re-establishment
Hydrocarbon Remediation
Petroleum hydrocarbons from spills and legacy contamination require targeted treatment approaches. We employ electrokinetics, soil washing, and bioremediation to break down and remove hydrocarbons.
- BTEX and F1-F4 fraction removal
- Bioremediation
- Soil washing and thermal treatment
- Post-remediation monitoring
Heavy Metals Remediation
Heavy metals such as lead, arsenic, and barium from drilling activities pose long-term environmental risks. Our stabilization and extraction techniques immobilize or remove metals to meet regulatory criteria.
- Arsenic, Lead, Mercury, and Cadmium
- Soil stabilization and solidification
- Phytoremediation programs
- Risk-based closure assessments
About TERRAVOLT
Trusted Environmental Remediation Across Western Canada
TERRAVOLT Soil Remediation Inc. specializes in the assessment and remediation of contaminated sites within the oil and gas sector. With over 15 years of experience, our team has successfully remediated hundreds of wellsites, pipeline rights-of-way, and facility leases across Alberta, Saskatchewan, and British Columbia.
We work closely with environmental consultants, landowners, and regulatory bodies to design cost-effective remediation strategies that achieve closure efficiently while protecting the environment for future generations.
Regulatory Expertise
Full compliance with Alberta Environment and Protected Areas (AEPA) standards and federal CCME guidelines.
Environmental Stewardship
We go beyond cleanup. Our remediation restores ecosystems and supports long-term land productivity.
Proven Results
Hundreds of successful site closures through partnerships & rigorous remediation practices meeting standards set by the Alberta Energy Regulator.
Industry Partnerships
Trusted by major producers, junior operators, and environmental consultants across Western Canada.
Our Approach
From Contamination to Closure
Our systematic four-phase approach ensures every project is executed with precision, transparency, and full regulatory compliance from initial assessment through final closure.
Site Assessment
Comprehensive environmental site assessment including soil sampling, groundwater monitoring, and contamination delineation to characterize the full extent of impact.
Remediation Planning
Development of a site-specific remediation action plan including technology selection, regulatory consultation, timeline, and cost estimation for stakeholder approval.
Active Remediation
Execution of the approved remediation program using proven techniques including excavation, soil decontamination, electrokinetics, bioremediation, and soil amendment application.
Verification & Closure
Confirmatory sampling, regulatory reporting, and submission of closure applications to achieve a certificate of remediation and return the land to productive use.
Disposal Sites
Where Salt-Impacted Soil Goes Today
Fixed facilities accepting salt-impacted or oilfield-contaminated soils and waste across Alberta, British Columbia and Saskatchewan — landfills, salt caverns, terminals and treatment sites, current to July 2026. Shaded circles mark the principal oil & gas producing regions. Click any marker for operator, capability and source. Use the layer control to filter by facility type.
Compiled July 2026 from operator facility pages (secure.ca, r360canada.com, claystonewaste.com, remedx.net), Alberta EPA facility lists and CHWMEG facility reviews. Coordinates flagged “approximate” in popups are town-level (±2–10 km). Note: Secure divested 29 facilities (incl. 6 landfills, 2 caverns) to Waste Connections / R360 Canada in February 2024.

Electrokinetic Soil Remediation
Patented* ex-situ technology for efficient removal of salts, hydrocarbons & heavy metals
The Industry Challenge
Soil contamination poses a significant threat to human health, the environment, and the economy
$47.8B
Annual Global Soil Remediation Market (2024)
170,000+
Orphaned Wells in Alberta Alone
$37.9B+
Estimated Cleanup Liability (AER)

New O&G Wells Drilled Annually
- Traditional remediation methods are costly, energy-intensive, and generate significant waste
- Dig-truck-dump methods cost $270-$460 per ton (AER) and often just relocate the problem
- Salt contamination destroys soil structure and inhibits plant growth permanently
- Hydrocarbons from O&G spills persist for decades without proper treatment
The oil & gas industry faces mounting regulatory pressure with limited effective solutions.

What is Electrokinetic Remediation?
Applying electrical current to mobilize and extract contaminants from soil
Electromigration
Charged contaminants (ions) move toward opposite electrodes
Electro-osmosis
Bulk water flow carries dissolved contaminants toward cathode
Electrokinetic Forces
Combined effect creates net flow of contaminants
Key advantage: Effective in fine-grained soils (silts and clays) where other methods fail
Traditional In-Situ EK Limitations
Why conventional in-situ electrokinetic approaches have not achieved commercial success
Non-Linear Field Flow Dynamics
Electric field lines spread unpredictably in natural soil formations
Variable Soil Conductivity
Heterogeneous soil properties cause inconsistent treatment results
Limited Quality Control
Difficult to monitor and verify remediation progress in-ground
Slow Treatment Speed
Long treatment times (months to years) increase project costs
Cannot control electrolyte composition and flow in-situ
TerraVolt's patented* ex-situ approach solves these fundamental limitations.
