Langford is one of the Westshore municipalities on the Capital Regional District's Juan de Fuca distribution system. The CRD's 2024 report gives a median hardness of 17.2 mg/L as CaCO3 for that system. The water is very soft, so scale is rarely an issue and a softener adds little.
Health Canada: hardness above 200 mg/L is considered poor but tolerable; above 500 mg/L unacceptable.
