  2. Remediation of contaminated sites with cement - Wikipedia

    en.wikipedia.org/wiki/Remediation_of...

    A 1,300,000-square-foot (120,000 m 2) complex of mixed residential, office, retail and commercial space is being built on 15 acres (61,000 m 2) of former industrial land in downtown Victoria that was contaminated by lead. 10 tonnes of soil was treated with cement, which was mixed into the soil on site simply by using an excavator bucket. The ...

  3. In situ capping of subaqueous waste - Wikipedia

    en.wikipedia.org/wiki/In_situ_capping_of_sub...

    In-Situ Capping (ISC) of Subaqueous Waste is a non-removal remediation technique for contaminated sediment that involves leaving the waste in place and isolating it from the environment by placing a layer of soil and/or material over the contaminated waste as to prevent further spread of the contaminant. In-situ capping provides a viable way to ...

  4. In situ chemical oxidation - Wikipedia

    en.wikipedia.org/wiki/In_situ_chemical_oxidation

    Deep soil mixing requires specialized auger mixing equipment. In order to apply this method in-situ and in deep soil, the oxidant must be pumped to the point of mixing using a kelly bar (a piece of earth drilling equipment), or appropriate piping to the place where the soil needs to be oxidized. The soil then has to be mixed by using mixing blades.

  5. Soil salinity control - Wikipedia

    en.wikipedia.org/wiki/Soil_salinity_control

    Soil salinity control refers to controlling the process and progress of soil salinity to prevent soil degradation by salination and reclamation of already salty (saline) soils. Soil reclamation is also known as soil improvement, rehabilitation, remediation , recuperation, or amelioration.

  6. In situ thermal desorption - Wikipedia

    en.wikipedia.org/wiki/In_situ_thermal_desorption

    Thermal conductive heating is the application of heat to subsurface soils through conductive heat transfer. The source of the heat is applied via electric or gas powered thermal wells. Thermal wells are inserted vertically, or horizontally, in an array within the soil. Heat flows from the heating elements by conduction.

  7. Environmental remediation - Wikipedia

    en.wikipedia.org/wiki/Environmental_remediation

    Environmental remediation is the cleanup of hazardous substances dealing with the removal, treatment and containment of pollution or contaminants from environmental media such as soil, groundwater, sediment. [1] Remediation may be required by regulations before development of land revitalization projects.

  8. Soil vapor extraction - Wikipedia

    en.wikipedia.org/wiki/Soil_vapor_extraction

    Soil vapor extraction (SVE) is a physical treatment process for in situ remediation of volatile contaminants in vadose zone (unsaturated) soils (EPA, 2012). SVE (also referred to as in situ soil venting or vacuum extraction) is based on mass transfer of contaminant from the solid (sorbed) and liquid (aqueous or non-aqueous) phases into the gas phase, with subsequent collection of the gas phase ...

  9. Electrokinetic remediation - Wikipedia

    en.wikipedia.org/wiki/Electrokinetic_remediation

    Electrokinetic remediation, also termed electrokinetics, is a technique of using direct electric current to remove organic, inorganic and heavy metal particles from the soil by electric potential. [ 1 ] [ 2 ] [ 3 ] The use of this technique provides an approach with minimum disturbance to the surface while treating subsurface contaminants .
