Drinking water safety update for Princess Alexandra School, Diamond Jenness Secondary School, and the Trades Centre in Hay River

Public Service Announcement

Yellowknife — December 19, 2025

The Government of the Northwest Territories (GNWT) has received lead testing results for Princess Alexandra School, Diamond Jenness Secondary School, and the Diamond Jenness Trades Centre in Hay River.

Princess Alexandra School

Testing has confirmed that some 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 and water fountains at Princess Alexandra School will be out of service, and an alternative drinking water source will be provided, where it is not already in place.

The GNWT is taking the following steps to address the issue:

  • Identify and implement remediation measures for the affected water fixtures, such as replacing fixtures or installing filters. More detailed information on remediation measures will be added to the webpage  as it is confirmed.
  • Once all corrective measures are completed, follow-up testing will be carried out and reported to the Office of the Chief Public Health Officer for health risk assessment.
  • Use of 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.

Diamond Jenness Secondary School

Testing has confirmed that some 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, Diamond Jenness Secondary School is required to flush all affected fixtures for three minutes each morning before use. All sinks and fountains remain available and safe to use. Drinking water fixtures identified in the Public Health Order will remain in service with the flushing protocol in place until mitigation measures are completed.

The GNWT is taking the following steps to address the issue:

  • Identify and implement remediation measures for the affected water fixtures, such as replacing fixtures or installing filters. More detailed information on remediation measures will be added to the webpage  as it is confirmed.
  • Once all corrective measures are completed, follow-up testing will be carried out and reported to the Office of the Chief Public Health Officer for health risk assessment.

Diamond Jenness Trade Centre

Water testing for the Diamond Jenness Trades Centre in Hay River is complete. Testing has confirmed that all water fixtures show lead levels below the maximum acceptable concentration (MAC) set out in the Guidelines for Canadian Drinking Water Quality.

No remediation or mitigation measures are required, and the Diamond Jenness Trades Centre can use sinks and water fountains normally.

Water testing at Princess Alexandra School, Diamond Jenness Secondary School, and the Diamond Jenness Trades Centre is part of the GNWT’s commitment to test drinking water in every school in the territory. A priority-based protocol guides the order in which schools are tested, based on factors such as facility age, previous water quality information, and the age of students. While the protocol determines sequencing, the commitment remains the same: all schools will be testing using a science-based approach that reflects Health Canada’s guidance and the conditions of the North.

When GNWT staff are already scheduled to travel to a community, and testing can be incorporated, the GNWT may proceed at that time, even if the school was not identified among the highest priorities.

The GNWT will support an Education Body that chooses to safely provide alternate drinking water as a precaution while testing and remediation continue. The GNWT will reimburse reasonable, cost-effective expenses so that no school hesitates to act out of concern for budget impacts.

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.
