Karlsfeld is one of the few places in this dataset with soft water: the municipal analysis of July 2024 gives 46.4 mg/L CaCO₃, one value for the whole municipality. It is a one-off analysis and no newer report was found, so the figure may shift slightly. At this level limescale is rarely a problem and a softener is usually unnecessary.
German law (WRMG) uses 3 bands: soft < 8.4 °dH, medium 8.4–14 °dH, hard > 14 °dH.
