An Iqaluit city official told CBC News that an underground fuel spill found near the water treatment plant could explain why the city had to declare an emergency due to fuel-contaminated drinking water. "The team located an underground spill that showed signs of historic fuel adjacent to the water treatment plant in an inaccessible, below-ground void," Amy Elgersma, Iqaluit's chief administrative officer, told Mary Tatty, host of CBC's noon hour program, Nipivut.
