PFAS drinking water rules in Northwest Territories, the agency and citation behind them, how they compare to the Health Canada Objective of 30 nanograms per litre for the sum of 25 PFAS compounds, and the federal sites in Northwest Territories where the Government of Canada has recorded PFAS as a contaminant of concern.
This is the Canada view of the North American PFAS dataset. The complete dataset, including all 3,452 US systems and 97 Canadian sites, lives on the main PFAS contamination map.
Guidance value only
NWT adopts the HC Objective; small-community PWS testing expanding under 2024 federal-territorial funding. No enforceable jurisdiction-specific PFAS drinking water number was located in a primary source at the last review.

From the Federal Contaminated Sites Inventory, ordered by federal priority classification. The inventory records which contaminants are present at each federal site, not the measured concentrations, so these entries show where PFAS has been identified rather than how much was found.

The map is built from the US EPA Fifth Unregulated Contaminant Monitoring Rule, a United States programme. Canada has no equivalent national monitoring dataset for PFAS in drinking water. Sampling is run by provincial regulators and individual utilities, and results are published in their own reporting. The regulatory detail above is compiled from the NWT Environment and Climate Change source listed in the citations.
Every count above is read straight from a published government file. Nothing is modelled, averaged, or estimated. The rules below are the exact rules used to produce the figures for Northwest Territories.
Open the inventory source page
EPA UCMR 5 does not apply. UCMR 5 is a United States drinking water programme, so it produces no results for Northwest Territories. No US figure is reused or scaled to stand in for Canadian data.
Which sites are listed. Inventory records whose province field is NT and that carry the PFAS contaminant code. That gives 3 sites in Northwest Territories.
Site records, not samples. The inventory reports site status, classification, custodian, and affected media. It does not publish drinking water concentrations, so there is no Canadian equivalent of the US nanogram per litre figures.
Reporting lag. Custodian departments update their records on their own schedule, so a site may have progressed since it was last reported.
Limits and rules. The Northwest Territories standard shown above comes from NWT Environment and Climate Change, No jurisdiction-specific PFAS standard located; Health Canada Objective applies as guidance, reviewed 2026-08-13.
