Drinking Water safety update for Łı́ı́dlı̨ı̨ Kų́ę́ Elementary and High School, Mackenzie Mountain School, Fort Simpson Student Residences, Echo Dene School, Mezi School

Public Service Announcement

Yellowknife — September 22, 2026

Work to remediate fountains and sinks at Łı́ı́dlı̨ı̨ Kų́ę́ Elementary School and Łı́ı́dlı̨ı̨ Kų́ę́ Regional High School, Fort Simpson; Mackenzie Mountain School, Norman Wells; Fort Simpson Student Residences, Fort Simpson; Echo Dene School, Fort Liard; Mezi School, Whatì, are complete. The Office of the Chief Public Health Officer (CPHO) has lifted the Health Orders previously in place for these schools, following confirmation that lead levels in drinking water are within Health Canada guidelines.

Standard operating procedures are being developed to support ongoing maintenance – including filter replacement and routine re-testing – to ensure the water remains safe over time.

Across the territory, fixture mitigations are under way. Of 53 sites tested, 28 have now been confirmed to have lead levels below standards set by Health Canada. Work will continue to progress over the following months as supplies are delivered to sites.

As the work is completed, signs are being installed in schools to show staff and students where they should get drinking water. These approved drinking water sources may include water fountains, bottle-filling stations, kitchen taps, and other fixtures specific to each school program. A “Do Not Consume” sign does not mean that a fixture failed water quality testing or is unsafe to use. They are being installed as a precaution to clearly identify the water sources that will be regularly tested, monitored, and maintained for drinking water quality.
