Hardness of Danish drinking water
Map showing information about drinking water hardness (dH) at the level of water supply areas of public waterworks in Denmark based on quality-assured data, extracted from the national well-database Jupiter in September 2023. The hardness degree is based on the concentration of calcium and magnesium in the drinking water and has importance, for example, for the soap dosage when washing clothes: hard water requires more soap than soft water. Drinking water hardness may vary considerably from location to location and in time. Contact your water utility company to get the updated and precise figures.

The map is based on the latest available hardness information at the water supply areas of public waterworks. The public waterworks metadata and drinking water analyses of Ca, Mg and total hardness were extracted from the Jupiter database on 6 September 2023. The water supply areas are from Schullehner (2022, https://doi.org/10.34194/geusb.v49.8319). Data were quality assured, filtered, aggregated and linked together.
