The results of water quality testing in Iqaluit showed "exceedingly high concentrations of various fuel components" in one of the city's water tanks, the city's chief administrative officer said Friday at a news conference, as residents learned their water supply will remain undrinkable until at least mid-next week. While officials said the water could contain diesel or kerosene the territory's top doctor doesn't see long-term health concerns for those who drank the water.
