“The boil water advisory is a precautionary measure because water is not filtered through normal water treatment processes,” the department said in a statement.
The statement said residents should boil their water for a full minute if it is to be used for drinking, preparing infant formula, washing fruits and vegetables, cooking and brushing teeth.
Iqaluit residents were unable to consume tap water for two months last fall after it was discovered to be contaminated with fuel.
The city said an old fuel tank buried next to the sewage treatment plant was the source of the previous contamination, and residual traces of fuel entered the distribution system again last week.
The city said engineers and experts are on hand to find out how the fuel got into the water again.
Water is pumped from Lake Geraldine, Iqaluit’s water source, and delivered to residents without going through the treatment plant.
The city said the bypass system chlorinates the water, but residents may notice discoloration or a different taste or smell.
“Residual hydrocarbons from the historic fuel tank discovered and removed last fall, entered the distribution system and were noted on the water treatment plant’s real-time monitoring station,” the city said. .
“Identification of the exact path of contamination as it entered the distribution system is ongoing.”
