Lab water test for Miramichi taps

Municipal reports cover the plant. A Tap Score kit tests the water at a Miramichi tap for a broader contaminant panel.

Reading this page

Miramichi's most recent drinking water sample (2026-07-22) reports hardness of 204 mg/L, classified as very hard, and pH 7.7, drawn from a surface water source and treated at Miramichi Water Treatment Plant. Lead measured 0.4 μg/L and fluoride 0.5 mg/L.

Free chlorine measured 0.9 mg/L in this sample. E. coli was detected in this sample; check for an active boil water advisory before drinking untreated tap water.

Miramichi's hardness of 204 mg/L is above 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.

All monitored parameters meet Health Canada guidelines.

Health parameters compliant; minor aesthetic factors such as hardness or pH near guideline edges.

Water softeners for hard water

Very hard water. Whole-house softeners are the high-ticket fit; salt and test kits support the install.
