Reading this page

Vancouver's most recent drinking water sample (2026-07-22) reports hardness of 22 mg/L, classified as soft, and pH 7.6, drawn from a mixed water source and treated at Vancouver Water Treatment Plant. Lead measured 0.1 μg/L and fluoride 0.7 mg/L.

Free chlorine measured 0.6 mg/L in this sample. No E. coli was detected in this sample.

Vancouver's hardness of 22 mg/L is below the British Columbia average of 139 mg/L across 31 tracked municipalities, with a provincial average pH of 7.5.

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 metric and provincial comparison first, then the source footer for the underlying dataset.

Health parameters meet Health Canada limits; turbidity above the 1 NTU typical target.

One or more parameters exceed a Health Canada drinking water guideline or turbidity target.
