Graded against Health Canada drinking water guidelines
Ingersoll hardness is 271 mg/L — pitcher filters improve taste but will not soften water. Size a metered whole-house softener for scale, and add under-sink carbon for drinking chlorine.
OpenStats pick for Ingersoll’s 271 mg/L hardness — metered whole-house softener sized for very hard Canadian tap water
Ingersoll: under-sink carbon for drinking water (chlorine 1.2 mg/L) — does not remove hardness minerals
Ingersoll’s 1.2 mg/L chlorine — bestselling shower filter on Amazon.ca
Verify 271 mg/L hardness at your tap before buying salt and sizing a softener

Ingersoll's drinking water earns Grade C (Fair). Hardness is 271 mg/L (very hard), and pH is 7.4 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 0.5 mg/L against a guideline of ≤ 1.5 mg/L.

Watershed to tap
How Ingersoll 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.
Groundwater
Research confidence: high
Multiple Ingersoll Water Treatment Facilities (per-well sites)
Secure groundwater. Most sites: oxidation/filtration for H₂S, iron, manganese; ferric sulfate/chloride aids; sodium hypochlorite or chlorine gas. Wallace Line WTF offline in recent reports.
Oxford County system; water tower (~2,840 m³) and Merritt Street reservoir (~3,290 m³); ~14,900 people.
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.
