Lindesnes has four supply systems. Skadberg Vannverk, by far the largest, reports 37.5 mg/L CaCO₃ for 2025, while the smaller systems are between 3.9 and 15.3 mg/L. The figure here is the median of the four, 11.1 mg/L, so it is lower than what most residents receive. Skadberg's value is the better guide for the main settlements.
Norwegian waterworks report hardness in °dH or mg/L Ca; most supplies are very soft.
