Soil Treatment Facilities (STF) are utilized for receipt of contaminated soils that can be treated to levels approved for beneficial re-use. Jurisdictional regulations govern requirements of the facilities engineering and operations through formal permitting processes. Facilities are generally located adjacent to Municipal Solid Waste Landfill facilities so that treated soils can be re-used as Alternative Daily Cover (ADC) material for low density municipal solid waste. Chemical analysis is completed by clients and reviewed by technical staff to understand levels of contamination and ensure that treatment can be achieved. Soil is received and treated during summer months which offer more conducive conditions for material handling and promotion of hydrocarbon degradation. Once soil is treated it can be reused which eliminates long term liability associated with disposal.
KBL developed a STF in Yellowknife adjacent the city landfill in a former rock quarry. The facility has been engineered to accommodate contaminated soils as well as waste water and snow. Materials are treated and soil is beneficially re-used by the City as ADC and water used for dust suppression in adjacent quarry operations or released once confirmed to meet applicable criteria. Additionally KBL has an existing contract to market, operate and manage a STF for the Town of Hay River, NT. This facility is adjacent to the Municipal Solid Waste Landfill and has been engineered to accommodate contaminated soils. Soil is treated and once confirmatory sampling has been completed and chemical analysis illustrates that soil meets regulatory objectives, it is used as ADC at the landfill.
