Stadtwerke Lüdenscheid's Jubach waterworks has a 2025 annual mean of 50.0 mg/L CaCO₃, among the softest values in our German data. The Sauerland rock holds little lime, which fits soft water. The PDF contains a printed calcium value that does not match the total, so we used the alkaline-earth sum. Descaling needs are minimal.
German law (WRMG) uses 3 bands: soft < 8.4 °dH, medium 8.4–14 °dH, hard > 14 °dH.
