The Saskatoon Landfill does not accept contaminated soil for disposal; however, it does accept ‘clean fill’ for the use as daily and intermediate cover at no charge. ‘Clean fill’ is defined by the City of Saskatoon (COS) as soil materials that do not contain any foreign debris (such as but not limited to wood, stumps, branches, concrete, asphalt, metal, plastics, ceramics and masonry materials, rocks greater than 6 inches in diamter, and refuse) and have chemical concentrations of regulated substances below applicable provincial criteria. These regulated substances include petroleum hydrocarbons (eg: fuel, oils, hydraulic fluid, etc), polycyclic aromatic hydrocarbons (ash, cinders, coal slag, etc), polychlorinated biphenyls (transformer fluids), heavy metals (arsenic, cadmium, chromium, lead, mercury), chlorides, and volatile organic compounds (dry cleaning chemicals, pesticides, etc).
Any clean fill soil delivery to the Saskatoon Landfill that exceeds one load from a single source site must have prior approval from the Environmental & Corporate Initiatives Division (ECI) in order to ensure that the materials meet the Landfill Maximum Allowable Concentrations for Daily and/or Intermediate Cover Criteria as set by the Saskatchewan Ministry of Environment in their Saskatchewan Environmental Quality Guidelines. Any chemical substance that is present within the soil that is not explicitly indicated above will be considered on a case by case basis.
