Range across supply zones: 75–251 mg/L.
South Burnett Regional Council supplies Kingaroy, and its 2024-25 drinking water report lists a treated-water hardness of 173.0 mg/L CaCO₃. Measurements are wide, from 75.0 to 251.0 mg/L, so the level changes over the year, probably with the mix of source water. This is in the hard range: expect noticeable scale in kettles and hot-water systems, and consider a softener if it bothers you.
Australian Drinking Water Guidelines: aesthetic target ≤ 200 mg/L CaCO₃.

What it means at home
- Fast scale on taps, shower screens and kettle; white spots on glassware.
- Water heater: efficiency loss and element failures within years if unprotected.
- Dry skin and dull hair after showering are common.
- Softener recommended; jug or reverse osmosis for drinking.
How much salt will you use for softening?
Recommended, especially with a heater or boiler: scale cuts efficiency and shortens its life.
Descale a coffee machine or kettle about every 2 months (typical manufacturer guidance for this hardness).
