Case Study:

  • 1.2 hectare1 Property (landfill) that was filled in with a wide variety of materials (cinders, ashes, metals, wood, glass)1 at the turn of the twentieth century2.
  • Estimated waste quantity 9,000 cubic metres impacted soils and 1,000 cubic metres of waste1.
  • Contamination of concern: arsenic, boron, lead and zinc exceeding MOE criteria;  manganese and sodium exceeding 1994 MOE Ontario Drinking Water Objectives1.
  • Development proposal for the property requires a detailed Certificate of Property Use (CPU)2 which requires considerable engineering and financial commitments to contain contamination.
  • The CPU also restricts land use “Refrain from using the Property for any of the following use(s): Any type of property use specified in O.Reg.153/04, other than Parkland Use” and “Refrain from constructing any building for human occupancy.”2.

Where is this property? Lansdowne Park.  

If a small (1.2 hectare, 10,000 cubic meter) hundred year old  landfill can have this type of impact; what impact will the 8,744,000 cubic meter Carp Dump have in the future? Why would a dump expansion even be considered?
