The Government of the Northwest Territories (GNWT) has received lead testing results for Helen Kalvak School in Ulukhaktok. Testing has confirmed that some drinking water fixtures show lead levels above the maximum acceptable concentration (MAC) set out in the Guidelines for Canadian Drinking Water Quality. As a result, the Office of the Chief Public Health Officer (OCPHO) has issued a Public Health Order for the school.
Effective immediately, affected water fixtures at Helen Kalvak School will be out of service and an alternate drinking water source will be provided.
The GNWT is taking the following steps to address the issue:
- Signage placed on all affected water fixtures prohibiting access.
- Once all corrective measures are completed, follow-up testing will be carried out and reported to the OCPHO for health risk assessment.
- Water service at the affected fixtures will only resume once new safety systems are in place, testing confirms the water meets all health standards, and approval is provided by the OCPHO.
Water testing at Helen Kalvak School is part of a territory-wide school testing protocol that uses a priority-based approach guided by national best practices and advice from the OCPHO. Priorities are based on factors such as facility age, existing water quality data, and the age of students. The protocol follows Health Canada’s guidance and is adapted to the unique conditions of the NWT, where remote locations, trucked water systems, and older infrastructure can pose additional challenges.
When travel to a community is already planned and testing can be incorporated NWT may proceed even if the school was not identified among the highest priorities.
The GNWT remains committed to ensuring safe drinking water in all schools and will continue monitoring systems, conducting regular testing, and sharing updates as the territory-wide testing program progresses.
