Some residents of Fort Good Hope, N.W.T., say they've spotted surface contaminants on the Mackenzie River after Imperial Oil reported a spill last week from a produced water line at its Norman Wells, N.W.T., operation. "We're all concerned since I know I saw something in the water," said Jim Tobac, a resident of Fort Good Hope. "And somebody went by it with a boat and it looked like oil or something." Fort Good Hope is located downstream from Norman Wells. Tobac said that when the community heard that there was potentially a spill in the Mackenzie River, people started pulling their fishing nets from the water. Additionally, he said it's alarming for the community because their drinking water is from the river.
