  • Remediation Technologies - Bioremediation

    Bioremediation is the treatment of contaminated material involving the natural degradation of contaminants by bacteria. This process is particularly suitable for hydrocarbon contaminants such as petrol and diesel range organics. The rate of decomposition can be greatly increased by the addition of nutrients and by controlling moisture, ...

  • Surfactant Flushing

    Mobilizing contaminants for efficient mobilization and extraction. Surfactant flushing involves injecting a surfactant mixture into an aquifer impacted with Non-Aqueous Phase Liquids (NAPLs) to mobilize them. The surfactant and the mobilized NAPL are then removed through extraction wells, and either treated on-site or disposed of off-site. The ...

  • Chemical Oxidation Services

    One of the first in-situ methods of environmental remediation after bioremediation, Chemical Oxidation uses powerful oxidizing compounds tochemically treat contaminated soil and groundwater in place, or “in-situ”. When oxidant solutions, such as potassium permanganate or sodium persulphate, are injected into the subsurface, they spread ...

  • Chemical Reduction

    Harnessing powerful reducing compounds to chemically mitigate impacts in place. The other half of a redox reaction, chemical reduction results in the gain of electrons. One of the reactants in the reaction is oxidized, losing electrons; the other reactant is reduced, gaining electrons. In In-Situ Chemical Reduction (ISCR), reducing ...

  • Soil Vapour Extraction Systems

    Effectively removing volatile compounds from the vadose zone. Also called “in situ soil venting” or “vacuum extraction”, Soil Vapour Extraction systems reduce concentrations of volatile constituents absorbed into the subsurface by converting them from the solid (sorbed) and liquid (aqueous or non-aqueous) phases into the ...
