Squamish takes its water from the Powerhouse Springs wells. The District's 2025 report includes a laboratory sheet for a blended sample taken on 11 June 2025, showing 21.9 mg/L hardness as CaCO3. It is one sample, but the report describes the source water as soft. Scale is rarely an issue.
Health Canada: hardness above 200 mg/L is considered poor but tolerable; above 500 mg/L unacceptable.
