Lab water test for Tecumseh taps

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

Reading this page

Tecumseh's drinking water earns Grade C (Fair). Hardness is 192 mg/L (very hard), and pH is 7.5 against Health Canada's 6.5–8.5 guideline.

Lead at 0 μg/L is below the 5 μg/L maximum, and fluoride is 0.6 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 Tecumseh 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

Groundwater

Research confidence: medium

Source waters

  • groundwater

Treatment plants

  • Tecumseh 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.
