The City of Iqaluit says that investigators have found a historic fuel spill beside the water treatment plant that may be the source of contamination in its water supply.

Testing is being done to confirm the spill is the source of the contamination. There is still no timeline for when the city’s tap water will be safe to drink.

On October 12, the city and the Government of Nunavut Health Department told Iqalummiut not to drink the tap water from the municipal water supply because it was suspected it had been contaminated with fuel.
