Range across supply zones: 94–126 mg/L.
Penticton's 2024 treatment plant report includes quarterly lab results from distribution stations around the city, ranging from 93.7 to 126 mg/L as CaCO3. The range shown is that spread, and the figure is its midpoint. The city's source waters, Okanagan Lake and Penticton Creek, differ in hardness, so values vary by area. Expect some scale over time.
Health Canada: hardness above 200 mg/L is considered poor but tolerable; above 500 mg/L unacceptable.

What it means at home
- Visible kettle scale every few weeks; vinegar or citric acid is enough.
- Water heater and washing machine: some long-term scale; a scale inhibitor slows it.
- Dishwasher: medium salt setting.
- Softener optional; pays off mainly with a gas boiler or tankless heater.
How much salt will you use for softening?
Optional. A scale inhibitor or a small softener protects the heater; soap savings are modest.
Descale a coffee machine or kettle about every 3 months (typical manufacturer guidance for this hardness).
