For several months, bitumen from the Athabasca oil sands has been leaching out of the ground near Cold Lake, Alberta, so far amounting to roughly half of the oil leaked in the Enbridge-caused disaster in Kalamazoo, Michigan. Nearby sites of high-pressure steam injection used to extract the bitumen (and which is already associated with violent seismic activity in natural gas fracking operations) are suspected to have caused fractures that push bitumen "sideways" and out to the surface. As Vice reporter Sarah Berman notes, "The oozing leaks will continue until the underground pressure subsides. How long that will take is anybody’s guess." While tons of contaminated vegetation and dead animals have been removed from the sites, access to the region and to government data by First Nation representatives has been repeatedly denied.
Sometime Sunday evening, an oil pipeline burst over Talmadge Creek near Marshall, Michigan, spilling an estimated 840,000 gallons of oil into the Kalamazoo River. [more inside]
