Public Health Advisory Rescinded for the Community of Hay River, Enterprise, Kátł’odeeche First Nation, and Ka'a'gee Tu First Nation (Kakisa)
NORTHWEST TERRITORIES (February 3, 2026) - The Chief Environmental Health Officer is advising all residents in the community of Hay River, Enterprise, Kátł’odeeche First Nation and Ka'a'gee Tu First Nation (Kakisa) that the precautionary Public Health Advisory for drinking water has been lifted.

Residents who receive their water from the Hay River Water Treatment Plant were asked to take precautions due to elevated levels of Trihalomethanes (THMs) in the water.

The Community Government of Hay River reported monthly results of THMs, and the current annual running average has come below 100 µg/L. The drinking water now meets the Guidelines for Canadian Drinking Water Quality. Normal use of drinking water may resume.

The Environmental Health Unit will continue to monitor results from the Town of Hay River Water Treatment Plant.
