Lab water test for Cochrane taps

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

Reading this page

Cochrane's drinking water earns Grade C (Fair). Hardness is 231 mg/L (very hard), and pH is 7.9 against Health Canada's 6.5–8.5 guideline.

Lead at 0.7 μg/L is below the 5 μg/L maximum, and fluoride is 0.7 mg/L against a guideline of ≤ 1.5 mg/L.

How to use this page: read the headline metric and provincial comparison first, then supply and treatment notes, then the source footer for the underlying dataset.

Supply and treatment

How Cochrane draws, treats, and distributes drinking water, from municipal and utility publications. Chemistry grades above come from separate parameter records; this section does not invent plant lab figures.

Source type

Mixed surface and groundwater

Research confidence: medium

Treatment plants

  • Cochrane Water Treatment Plant

    From municipal open data or regional estimate (verify locally).

Cited sources

Outbound municipal or utility citations pending. See methodology for how supply research is gathered.

Supply notes summarize published utility materials. They are not a substitute for the issuing authority's current notices or for a licensed tap test.

Health parameters meet Health Canada limits; turbidity above the 1 NTU typical target and very hard water.

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

Water softeners for hard water

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