The Canadian Armed Forces is now providing potable water in Iqaluit amid its ongoing water contamination crisis. The city has been under a state of emergency since Oct. 12, when staff confirmed evidence of fuel contamination in the city's treated water supply. Residents were told the water is unsafe to drink, even if filtered or boiled. The CAF is using mobile water treatment units to treat water from the Sylvia Grinnell River using reverse osmosis. It then transfers potable water to a designated city water truck that carries it to water filling depots at the Arctic Winter Games and the library parking lots.
