The City of Iqaluit says trace amounts of fuel have been detected in the Nunavut capital’s water supply. The city says an initial review of data from its real-time monitoring station indicates fuel entered the water on Monday and Wednesday. It says there have been no measurements above low-alarm thresholds, but the city is proactively opening distribution valves to flush the water. The city had already confirmed it was investigating after residents complained they could smell fuel in their tap water again.
