- Digital map
- Purpose
- The purpose of this map is to show the variation of drinking water (DW) hardness in Denmark based on the data available in 2023. DW hardness is an important technical characteristic of tap water in relation to precipitation of carbonates in water pipes, boilers and other hot water household appliances, as well as in relation to increased soap use. The data have also potential relevance to different authorities and industries.

- Statement
- 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.
