Soil remediation services

Soil remediation services in Alberta and across North America

Nelson provides soil remediation through mobile thermal treatment, in-situ programs and Earthworks excavation and disposal. From Acheson, Alberta, the team assesses the contaminants, material quantities, access and cleanup objectives before selecting a site-specific approach.

Assessment

What soil remediation needs to establish

Soil remediation manages contaminated ground to meet the objectives for a site and its intended use. Start with the site history, analytical results, affected soil and groundwater, exposure pathways and applicable criteria. The assessment establishes what must be treated, removed or managed, and what the project must demonstrate.

A treatment plan defines the source boundary, excavation or in-situ access, material handling, water management and verification. Testing treated soil is one part of the record; remaining ground, groundwater and residual materials may require separate confirmation.

Treatment selection

Match the method to the material and the site

Mobile ex-situ thermal desorption processes excavated soil containing suitable organic contaminants. In-situ programs address affected soil or groundwater where leaving the material in place fits the geology and access. Earthworks provides excavation, haulage, authorized disposal and restoration where those pathways fit the scope.

Petroleum hydrocarbons, BTEX, PAHs, PCBs and legacy dioxin residues require contaminant-specific treatment and verification. Metals cannot be destroyed by heating. Mixed materials may need segregation or stabilization and an authorized residual destination. Nelson's PFAS work remains pilot-validated, including NATO STO test-bed participation; a hydrocarbon result does not establish PFAS performance.

Alberta

Local project evidence and Alberta cleanup objectives

Establish the applicable Alberta Tier 1 or Tier 2 objectives, land use, soil texture and exposure pathways before choosing the remedy. Upstream oilfield waste, soil remediation and reclamation can involve different requirements. Meeting a sampled-soil criterion does not automatically establish a remediation or reclamation certificate.

Bear Hills on Louis Bull First Nation land and the Alberta legacy wellsite project provide local examples of thermal treatment of hydrocarbon-impacted soil. Use their project records to compare material type and treatment scope, rather than assume identical performance at another site.

Verification

Agree the evidence and responsibilities before mobilization

Define representative soil sampling, operational records, off-gas testing where relevant, water and residual management, and receiving-facility documentation. Identify who supplies each part of the completion record and which requirements the qualified project professional or regulator must review.

Treated material can be considered for reuse where analytical results, geotechnical suitability and applicable approvals support the intended use. Treatment, disposal, clean backfill and restoration can all contribute to one site-management plan.

Frequently asked

What is soil remediation?

Soil remediation manages contamination to meet site-specific cleanup and land-use objectives. Treatment, excavation, authorized disposal, stabilization and restoration are different contributions to that scope. The method follows the contaminant evidence, affected media, access and verification requirements.

Does Nelson provide soil remediation in Alberta?

Yes. Nelson operates from Acheson, Alberta, with hydrocarbon remediation project evidence at Bear Hills and Alberta legacy wellsites. The Thermal, In-Situ and Earthworks divisions assess treatment and material-management options against the particular site.

Can treated soil be reused?

Where representative results, geotechnical suitability and applicable requirements support the intended use, treated material can be considered for reuse. A passing treated-soil result does not by itself establish that every part of a site has met its completion requirements.

What should I send for an initial project discussion?

Send existing assessments, laboratory results, estimated material quantities, cleanup criteria and a site plan showing access and operational constraints. Identify uncertainties and missing information so the team can establish what further characterization or treatability work is needed.
