Reading this page

Moncton's most recent drinking water sample (2026-07-22) reports hardness of 24 mg/L, classified as soft, and pH 8, drawn from a surface water source and treated at Moncton Water Treatment Plant. Lead measured 0.5 μg/L and fluoride 0.5 mg/L.

Free chlorine measured 1 mg/L in this sample. No E. coli was detected in this sample.

Moncton's hardness of 24 mg/L is below the New Brunswick average of 155 mg/L across 7 tracked municipalities, with a provincial average pH of 7.7.

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 metrics first, then where the water comes from (map and tap story), then the parameter table and source footer.

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.
