German water hardness ranking
66 German cities water hardness ranking
Germany's water is too hard. Excessive water hardness can lead to more scale deposits in water pipes and household appliances. Many residents also report that washing hair with hard water can cause hair loss.
The water hardness (Wasserhärte) in Germany varies from region to region, with some regions having harder water and others having softer water. Germany uses °dH units to indicate the concentration of calcium and magnesium ions in each liter of water. Water with 0-8.4°dH is considered soft, while water with more than 14°dH is considered hard.
According to data from the German Water Hardness website, let's take a look at the water hardness rankings of 66 German cities to see which cities have the hardest water.

It can be seen that the water hardness is significantly higher in southern and eastern Germany, such as in Würzburg, because the proportion of limestone in the rocks in these areas is higher.
However, friends living in hard water areas don't have to worry. Hard water basically has no effect on health. Those who are concerned can also use water filters, water softeners, and other equipment to reduce the hardness of the water.
