The Municipality of Iqaluit reports that an underground fuel spill uncovered near the contaminated water tank is likely to be responsible for the problem.
In a statement released on Tuesday, city officials explained that they had discovered traces of a past spill while carrying out checks from a hole in the ground.
The water from the Iqaluit aqueduct has not been safe to drink since October 12, when analyzes confirmed the presence of petroleum hydrocarbons in a reservoir at the water treatment plant.
Other analyzes are currently being carried out to confirm whether the spill is the cause of the contamination of the water.
The municipality says it reported the spill to the Government of Nunavut and commissioned a professional firm to decontaminate the site.
No timeline has yet been announced for when people will be able to drink tap water again.
