Mixed-Waste Soil Remediation in Manitoba

Co-contaminated soil on Manitoba sites typically combines hydrocarbon with chlorinated solvent, PAH, or PCB fractions: rail yards, fuel distribution sites, industrial lands, and legacy electrical infrastructure. The Contaminated Sites Remediation Act[1] and its regulation[2] govern the remediation process, CCME Canada-Wide Standards reference the hydrocarbon fractions[3], and the federal PCB Regulations govern PCB fractions[4].

How Nelson handles mixed waste

Mixed waste streams are the reality of most industrial and legacy sites: hydrocarbons layered with PAHs, chlorinated solvents, heavy metals, PFAS, dioxin residues, and matrix variability that defeats single-technology approaches. Sending mixed waste to landfill converts a treatable problem into a permanent liability line item.

Nelson's RS-series thermal platform is engineered to handle mixed organic streams: hydrocarbons through gasoline-to-crude, PAHs, PCBs, dioxins, PFAS, creosote, and pesticides in a single treatment envelope. Inorganic co-contaminants are managed through the engineered treatment train, with confirmation sampling calibrated to each contaminant profile.

The platform is the same one Nelson operates on hydrocarbon, dioxin, and PFAS mandates. Mixed waste uses the same physics, with characterization-driven tuning of temperature, residence time, and treatment-train selection.

Proof: Nelson's mixed-organic destruction record spans hydrocarbon, dioxin, and complex industrial matrices across five continents. The Bear Hills and Tioga projects are on the public record; mixed-waste specifics are shared under NDA at scoping.

Operational reach in Manitoba

Mobilized from Acheson, Alberta by road. One mobilization treats the combined stream with engineered off-gas treatment sized for the full parameter set.

Frequently asked

Can one mobilization handle hydrocarbon plus solvent plus PCB?

Yes, the RS-series platform is engineered for co-contamination, with off-gas treatment sized for the combined stream and PCB fractions managed under the federal PCB Regulations[4].

Where do metals go?

Concentrated in a manageable residual stream characterized for end-disposition under the provincial framework[2].

Treatment approach · By contaminant

Heavy Metals (Arsenic, Mercury, Chromium, Lead)Regulated inorganic trace elements — including arsenic, mercury, hexavalent chromium, lead, cadmium, and nickel — that are toxic at parts-per-billion to parts-per-million levels, do not biodegrade, and are managed by immobilization, physical separation, or valence-state conversion.

ArsenicA naturally-occurring metalloid regulated at 10 μg/L in drinking water whose remediation is driven by oxidation state — mobile, toxic As(III) is oxidized to less mobile As(V) and coprecipitated with iron or bound into a stabilized matrix.

MercuryA globally-regulated heavy metal — listed under the Minamata Convention — whose remediation is dominated by indirect thermal desorption that vaporizes elemental Hg from soil and condenses it as a recoverable stream for offsite reclamation.

Hexavalent Chromium (Cr(VI))The oxidized, mobile, IARC Group 1 carcinogenic form of chromium — regulated at 10 μg/L in California drinking water — whose remediation is defined by in-situ chemical reduction to immobile, non-toxic Cr(III).

AsbestosA family of six naturally-occurring fibrous silicate minerals — regulated under US EPA NESHAP and OSHA — whose remediation is a containment and disposal problem, not a treatment problem: the fibers are chemically stable and cannot be biologically or thermally destroyed at practical scales.

SulfateThe SO₄²⁻ oxyanion released to groundwater and surface water from acid mine drainage, oilsands process water, industrial effluent, and gypsum-bearing geology; regulated for taste and osmotic effects and for downstream sulfide generation in anaerobic sediments.

Dioxins and Furans (PCDD/PCDF)A family of 210 chlorinated tricyclic aromatic congeners — including 2,3,7,8-TCDD — formed as unintended byproducts of combustion, chlorine chemistry, and legacy herbicide manufacture; persistent, bioaccumulative, and destroyed only by high-temperature thermal treatment.

PCBs (Polychlorinated Biphenyls)A family of 209 chlorinated biphenyl congeners manufactured from 1929 to 1979 as dielectric fluids, plasticizers, and heat-transfer oils — banned globally under the Stockholm Convention and listed as US EPA and Health Canada priority contaminants for their persistence, bioaccumulation, and dioxin-like toxicity.

Chlorinated Solvents (TCE, PCE, TCA, DCE, VC)Man-made chlorinated aliphatic hydrocarbons — tetrachloroethylene (PCE), trichloroethylene (TCE), 1,1,1-trichloroethane (TCA), cis-1,2-DCE, and vinyl chloride — that formed the industrial degreasing and dry-cleaning solvent market for four decades and left the densest DNAPL groundwater plumes in North America.

Chlorinated VOCs (CVOCs)Chlorinated volatile organic compounds: a family of chlorinated solvents including TCE, PCE, vinyl chloride, and DCE that migrate readily in soil vapor and groundwater and require chemical, biological, or thermal treatment.

In-Situ Chemical Oxidation (ISCO)In-situ chemical oxidation: injection of a chemical oxidant — permanganate, persulfate, or Fenton's reagent — directly into contaminated soil or groundwater to destroy dissolved-phase organic contaminants without excavation.
