A huge pipeline spill has released 22,000 barrels of oil and water into muskeg in the far northwest of Alberta.
The spill ranks among the largest in North America in recent years, a period that has seen a series of high-profile accidents that have undermined the energy industry’s safety record. The Enbridge Inc. pipeline rupture that leaked oil near Michigan’s Kalamazoo River, for example, spilled an estimated 19,500 barrels.
