Alberta Energy estimated oilsands mining projects had created about 220 square kilometres of tailings ponds by the end of 2013. The ponds are used to store water needed to separate heavy bitumen crude from sand and other impurities and contain water, silt, leftover bitumen and solvents. They have long been one of the industry's toughest environmental challenges.
