Reading this page
Brantford's most recent drinking water sample (2026-07-22) reports hardness of 266 mg/L, classified as very hard, and pH 7.4, drawn from a surface water source and treated at Brantford Water Treatment Plant. Lead measured 0.2 μg/L and fluoride 0.5 mg/L.
Free chlorine measured 0.7 mg/L in this sample. No E. coli was detected in this sample.
Brantford's hardness of 266 mg/L is above the Ontario average of 182 mg/L across 51 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 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 and very hard water.
Health parameters meet Health Canada limits; turbidity exceeds the typical 1 NTU aesthetic target.
