Fort McMurray, Alberta, CAN, 20090721: Chemical waste in a tailing pond at the Syncrude open pit oil excavation mine in Fort McMurray.
The tailing ponds are areas of refused mining tailings. They are a huge problem for the tar sand industry, as they take much longer to settle than projected. They are also a eye-sore, a tell-tale to how dirty the tar sand industry is.
