Site Remediation

Weeks Lake

Summit Earthworks completed this sensitive environmental remediation project on behalf of the Capital Regional District. The former unauthorized firearms practice and minor indiscriminate dumping activity lead to metals and hydrocarbon contamination at the Weeks Lake Gravel Pit area. The remote Weeks Lake project site is located approximately 40 Km northwest of Victoria. Weeks Lake and the surrounding area is within the Greater Victoria water supply area (GVWSA) and is accessed via gravel forest service roads. The project required onsite handling, management, transport & disposal of soils containing hazardous waste (HW), levels of leachable lead and other metals and hydrocarbon concentrations to IL+ land use standards. The project objectives were:

  • The onsite stabilization of HW lead impacted soils to bind the leachable lead (thus amending soils to IL+ standards) to
    make it acceptable for transport and disposal
  • Metals and hydrocarbons contaminated soil excavation, transport & disposal to our MoE permitted facility

General scope, outline and project activities include:

  • Metals and hydrocarbon contaminated soil excavation, transport & disposal to Summit Earthworks MoE permitted facility.
  • Amendment of leachable lead containing hazardous waste soil to non-hazardous (IL+) levels and transport/disposal to
    Summit Earthworks disposal facility.
  • Conduct soil sampling & data analysis on stabilized soil in compliance with the BC MoE guidelines.
  • Conduct soil excavation along gravel pit slopes, as per Geotech recommendation to avoid slopes failure.
  • The excavated contaminated soils were hauled via gravel truck from the remote forest site location to a barge loading facility
    near Victoria. Waste soils were loaded and transported via barge to Summit Earthworks MoE permitted soil disposal facility
    located in Mission, BC.
