Welcome to our water hardness directory, a comprehensive collection of the water hardness levels of many towns and cities. We have made it our mission to provide you with an easily accessible and user-friendly platform where you can quickly and easily determine the water hardness in your locality.
Thanks to the user-friendly search, you can quickly and easily find the water hardness in your area in our directory. However, if no value is entered there, you have the option of entering the water hardness yourself. We provide you with comprehensive guides so you know exactly how to do it. In this way you can actively contribute to expanding and improving our directory.
With our water hardness directory, we would like to give you valuable help to better understand the water quality in your locality and, if necessary, to be able to take appropriate measures. Welcome to us and good luck in finding the water hardness in your locality.

There are now many discussions about tap water. One of the most important topics of conversation is the distinction between hard and soft water. The nature of tap water is not the same everywhere. Rather, the tap water is subject to fluctuations in quality depending on the individual requirements. But what is even better? Soft or hard water? What is the difference and how can hard water become soft water. Here you will find all important information on the subject of water hardness.
What is water hardness?
The hardness of the water is determined by the concentration of hardness-forming elements in the water. The alkaline earth metals magnesium and calcium in particular belong to these hardeners, as well as very small amounts of strontium and barium. The hardness is calculated from the amount of magnesium or calcium ions in the water. Accordingly, hard water has more ions than soft water. Although calcium and magnesium are dissolved in water, they may combine to form insoluble substances such as lime. Hard tap water is therefore often recognized by limescale deposits on the tap. In a high concentration, the metal deposits cause damage and blockages in the pipes. The hardeners get into the groundwater via the soil or are transported into the water via aquifers. For comparison: Rainwater usually contains almost no hardening elements.
Pros and cons of hard and soft water
Soft water is better for drinking, watering plants and cleaning dishes. It has a disadvantageous effect on the formation of foam during the washing process and on the washability of soap when washing hands. Hard water helps to loosen encrustations on the dishes, but also requires more detergent or dishwashing liquid. If hard water is regularly used to operate heaters or household appliances (e.g. coffee machines or kettles), scale will eventually form on the appliances. In addition, hard water can contribute to calcification and clogging of the pipes in the long term. Soft water is therefore more suitable for domestic use.
How can hard water be made softer?
Filter systems are most successful in converting hard water into soft water. Here the tap water is freed from metals. This improves the usability of the water. Household appliances have a longer service life, the water is more digestible for plants and the general water quality is improved. Unfortunately, filters usually do not help to protect the pipes. Filters are only attached to the tap, so they have no influence on the hardness of the water inside the inlet pipes.
The quality of tap water has an impact on many areas of application. Whether it is used in plant breeding, as drinking water or in the household, soft water is generally to be preferred. Unfortunately, the quality of tap water always depends on the environment and the sanitary systems. It is therefore worth relying on a filter system for filtering metals. This allows consumers to quickly and easily convert hard tap water into soft water and then use it.
