Graded against Health Canada drinking water guidelines
Osoyoos hardness is 273 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 Osoyoos’s 273 mg/L hardness — metered whole-house softener sized for very hard Canadian tap water
Osoyoos: under-sink carbon for drinking water (chlorine 0.6 mg/L) — does not remove hardness minerals
Optional shower carbon for Osoyoos if chlorine taste bothers you
Verify 273 mg/L hardness at your tap before buying salt and sizing a softener

Osoyoos's drinking water earns Grade C (Fair). Hardness is 273 mg/L (very hard), and pH is 7.6 against Health Canada's 6.5–8.5 guideline.
Lead at 0.1 μg/L is below the 5 μg/L maximum, and fluoride is 0.7 mg/L against a guideline of ≤ 1.5 mg/L.
