The water supply of London, Ontario is threatened by shale fracking that may occur elsewhere in the province as well. Poisonous, flammable, and radioactive substances would flow into the Great Lakes; however, the municipal water supplies for London come from Lake Erie and Lake Huron.
London also is one of the areas in the province where Mooncor plans to explore for shale gas. There could be fracking inside the city — or immediately beside London. The green section of these maps shows where fracking might be done around London.
Those maps were made by overlaying this next one on the London area, using Google Earth.
That southwestern Ontario “Gas exploration” map is from a 2010 Toronto Star article about Mooncor’s plans for southwestern Ontario.
The London area around the shale deposits highlighted in a 2010-2011 report from the Environmental Commissioner.
