Health officials in the N.W.T. have lifted a drinking water advisory issued last fall for people in Hay River, Enterprise, Kátł'odeeche First Nation and Kakisa.
The chief environmental health officer said in November that residents should take precautions because of elevated levels of disinfection byproducts called trihalomethanes (THMs) detected in the water from the Hay River treatment plant.
In a news release on Tuesday, the chief environmental health officer said that testing at the plant now shows that the water meets federal guidelines for drinking water quality, and residents can go back to using tap water as normal.
The advisory in November recommended using filters or letting tap water sit for a day to allow THMs to partially evaporate.
Trihalomethanes are a by-product formed when chlorine reacts with organic matter in the water, such as decaying plants. Health officials said that extended exposure to high levels of THMs, meaning 70 years or more, could increase the risk of cancer.
