Whitehorse Water Hardness & Quality Report (2026)

The City of Whitehorse Water Utility draws its supply from five groundwater wells situated within the Yukon Territory. These wells tap into local aquifers, and the water is then blended at the Selkirk Pumphouse to ensure a consistent quality for residents. Recent shifts in the source groundwater's character have prompted the utility to investigate multi-barrier treatment strategies, acknowledging the potential vulnerability of the aquifer system. The City of Whitehorse relies entirely on these groundwater sources.

Whitehorse's water originates from groundwater aquifers within the Yukon Territory. The geology here, characterized by bedrock and glacial deposits, is rich in calcium and magnesium. This mineral-rich geological makeup is the reason for the water's hardness, which varies from well to well, ranging between 80 and 250 mg/L. The blending process at the Selkirk Pumphouse aims for a moderately hard final water, though recent quality changes suggest potential aquifer stress or surface influences.

For homeowners in Whitehorse, the water's significant hardness means you'll likely notice scale buildup on fixtures and a reduced lathering effect from soaps. Appliances like water heaters, dishwashers, and washing machines are especially susceptible to mineral deposits, which can shorten their lifespan and decrease efficiency. Installing a water softener is a practical step for managing maintenance costs and protecting these household systems, particularly those involving hot water. Residents can find detailed water quality information, including mineral content, in the City of Whitehorse's official Water Quality Report Card.
