Stadtwerke Eberbach lists total hardness for five supply points in its 2025 analysis. All are soft, at about 1 to 3 °dH, or 21.4 to 50.0 mg/L CaCO₃, with a median of 37.5 mg/L. The figures come from the tap-water columns of the table, not the raw-water wells that only feed the network. The source shows a year, not an exact sampling date, and the hardness depends on the supply point serving your street.
German law (WRMG) uses 3 bands: soft < 8.4 °dH, medium 8.4–14 °dH, hard > 14 °dH.
