Graded against Health Canada drinking water guidelines
Norfolk County hardness is 258 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 Norfolk County’s 258 mg/L hardness — metered whole-house softener sized for very hard Canadian tap water
Norfolk County: under-sink carbon for drinking water (chlorine 0.7 mg/L) — does not remove hardness minerals
Optional shower carbon for Norfolk County if chlorine taste bothers you
Verify 258 mg/L hardness at your tap before buying salt and sizing a softener
