Range across supply zones: 36–54 mg/L.
Nesttun is supplied by Bergen Vann. Bergen kommune publishes a range for the city, and the figure here is a median of 44.6 mg/L CaCO₃ within 35.7 to 53.6 mg/L. It is computed from the city-wide range, not measured in Nesttun. The water is soft, so limescale is mild and a softener is seldom worth the cost.
Norwegian waterworks report hardness in °dH or mg/L Ca; most supplies are very soft.
