A flowing river that turns to solid ice in October, freezing pipes and frosty arctic temperatures are all routine for Nunavummiut. But those issues were a first for a water treatment system previously used by the Canadian Armed Forces in places, including Haiti after the 2010 earthquake and the Philippines. Iqaluit has been under a state of emergency since Oct. 12 when fuel was found in the water at the city's treatment plant. Residents have not been able to drink tap water since then.
