Remediation

If you're dealing with historic hydrocarbon impacts, salt-affected soil, or waste that's been sitting on site for years, remediation is the critical step between "we have a problem" and "we have a reclamation certificate."

Terra-Sano provides remediation services across Alberta, combining our environmental expertise with in-house earthworks capabilities to manage contaminated sites. We resolve any issues, manage waste, and bring your site into compliance with cleanup standards required by regulators.

Planning & Regulatory Strategy

Remedial Action Plan Preparation and Implementation

You can't start digging contaminated soil without a plan. You require a documented approach that defines the contamination, remediation methods, cleanup standards, and verification of success.

Terra-Sano’s environmental professionals prepare Remedial Action Plans (RAPs) and their implementation, ensuring seamless execution from start to finish without the need for third-party contractors.

Remedial Reporting

Once remediation is complete, regulators want proof that you actually achieved cleanup standards. Our environmental team prepares remedial reports that document:

  • Pre-remediation site conditions and contamination levels
  • All remediation activities undertaken
  • Post-remediation soil sampling results demonstrating cleanup success
  • Waste disposal documentation and manifests

These reports are designed to satisfy AER requirements the first time, reducing the likelihood of deficiency letters or requests for additional work.

Field Execution & Contamination Management

Microbial Remediation

For many hydrocarbon-impacted soils, microbial remediation offers a cost-effective alternative that treats contamination on-site rather than hauling it to a landfill. Microbial remediation is most effective for petroleum hydrocarbon contamination in soil that's not heavily salt- or inhibitor-impacted. 

We excavate contaminated soil, place it in treatment cells if required, and optimize conditions for naturally occurring microbes that break down hydrocarbons. Through regular tilling, moisture management, nutrient addition, and monitoring, we accelerate the natural degradation process until the soil meets cleanup standards.

Sump Remixes

Old sumps are one of the most common contamination sources on inactive oil and gas sites. Historic sumps often contain a mix of drilling fluids, produced water, hydrocarbons, and salt-affected soil.

Terra-Sano handles initial characterizations, sump remix notifications and approvals, and remixing the sump to meet approved notifications.

Waste Management & Disposal

Waste Disposal

Once contaminated soil is excavated and characterized, it needs to go somewhere legal with proper documentation. We manage transportation to approved disposal facilities as well as waste manifesting and documentation.

Appropriate Landfill Classification

Not all contaminated soil can go to the same place. Alberta has different landfill classifications based on waste characteristics.

Getting this wrong is expensive. Send waste to the wrong facility, and you're paying to re-excavate, re-characterize, and re-dispose. Our environmental professionals ensure waste is properly characterized and classified before it leaves your site, so it goes to the right facility the first time.

Field Testing Equipment

Effective waste management starts with knowing what you're dealing with. Field testing guides laboratory decisions and helps us make decisions in the field.

Our field testing equipment allows us to:

  • Quickly screen soil for contamination levels during excavation
  • Delineate clean soil from contaminated soil to minimize disposal volumes, supported by lab data
  • Make real-time decisions about which material needs remediation versus disposal

Field testing means less guesswork and faster project execution. 

Project Management
That Ties It All Together

Remediation projects involve multiple phases, regulatory approvals, field execution, waste management, and final reporting. Our project management team coordinates everything so activities happen in the right sequence, nothing falls through the cracks, and your site moves steadily toward closure.

Whether we're managing remediation as part of a full site restoration or handling it as a standalone project, you get experienced oversight from people who've done this hundreds of times across Alberta.

Why We’re Trusted to
Remediate Sites Across Alberta

Because We Actually Do the Work (Not Just Write Reports)

Many environmental consulting firms will assess your site, write a remedial action plan, and then hand you a list of contractors to call. 

Terra-Sano eliminates that gap. Our environmental professionals write the plan, and our earthworks division executes it. Same company. Same project manager.

Because We Optimize for Cost, Not Just Compliance

Remediation can be expensive, but it doesn't have to be wasteful. Our integrated approach allows us to minimize disposal, collaborative remediation activities across multiple sites to reduce mobilization costs and sequence work efficiently to minimize equipment downtime. We're finding the most cost-effective path to clean your site.

Because We Know Contamination Is Rarely Simple

Our project managers and field crews have seen complications before. We know how to adapt, make informed decisions in the field, and keep projects moving forward even when conditions aren't ideal. You're benefiting from years of experience managing Alberta's variable site conditions.

Because We Understand the Pressure You're Under

Contaminated sites are liabilities. You need contamination fixed, not studied indefinitely. Our team understands that urgency. We move sites from "contaminated liability" to "remediated and ready for reclamation" as efficiently as possible, keeping you informed throughout the process and delivering results that satisfy regulators.
