Where it starts
Groundwater
Research confidence: high
Named source waters
- Riverdale / Selkirk Aquifer (Yukon River-recharged groundwater)
- Schwatka Lake (historic primary source; potential future backup after treatment upgrades)
Treatment plants
Selkirk Pumphouse
Central Riverdale facility where production-well water receives sodium hypochlorite disinfection before distribution; currently the sole municipal treatment step.
How it reaches your street
Municipal piped system is supplied from roughly seven Riverdale Aquifer production wells. Water is chlorinated at Selkirk Pumphouse and monitored continuously there plus weekly at many distribution sites. Some residents use private wells or trucked tank water outside the piped system.

Reading this page
Whitehorse's most recent drinking water sample (2026-07-22) reports hardness of 149 mg/L, classified as hard, and pH 7.7, drawn from a surface water source and treated at Whitehorse Water Treatment Plant. Lead measured 0.4 μg/L and fluoride 0.5 mg/L.
Free chlorine measured 0.9 mg/L in this sample. No E. coli was detected in this sample.
Water hardness measures dissolved calcium and magnesium; it affects soap performance and appliance scaling but carries no Health Canada health-based limit.
These readings summarize a single compliance snapshot, not a certification of the water reaching your tap. Test your own water periodically, especially on a private well, and consider a softener if hardness is classified hard or very hard.
How to use this page: read the headline metrics first, then where the water comes from (map and tap story), then the parameter table and source footer.
All monitored parameters meet Health Canada guidelines.
All health parameters meet Health Canada guidelines with comfortable pH, hardness, and turbidity.
