In Alberta, toxic waste spill may be biggest of all recent disasters in North America

A leak in Northern Alberta involving at least 9.5 million liters of toxic waste from an oil and gas operation is the third major leak in a region where "residents are now questioning whether enough is being done to maintain aging energy infrastructure." I'm gonna go with no. The spill was first detected June 1, but only Wednesday did Houston, TX-based operator Apache Corporation release an estimate of the leak's size.

“Every plant and tree died” in the area touched by the spill, said James Ahnassay, chief of the Dene Tha First Nation, whose members run traplines in an area that has seen oil and gas development since the 1950s.
