Lower Murray Water's 2024-25 annual drinking water quality report gives a hardness of 43.3 mg/L as CaCO₃, which is soft. The report states one figure for the supply, so we show no range. With water this soft, scale is unlikely to be a problem, and it is worth following the dosing guidance on detergent packs rather than adding extra.
Australian Drinking Water Guidelines: aesthetic target ≤ 200 mg/L CaCO₃.
