Range across supply zones: 36–86 mg/L.
The District of Summerland's 2025 drinking water report gives a calculated average hardness of 55.4 mg/L as CaCO3, with results from 35.6 to 86.0 mg/L. That is soft to moderately soft water, and the spread means the figure shifts through the year. Health Canada sets no health-based limit for hardness. Scale is light, so a softener is rarely needed.
Health Canada: hardness above 200 mg/L is considered poor but tolerable; above 500 mg/L unacceptable.
