How hard is the water in Valangin?

EVN Wasser GesmbH publishes a total hardness of 15 °dH for the supply zone 2042, Großsnondorf (hardness range hard). The hardness range is a classification under the German Detergents and Cleaning Products Act (soft below 8,4 °dH, medium 8,4 to 14 °dH, hard above that) and not a quality verdict — it indicates how much calcium and magnesium is dissolved in the water. Basis: 2026-02-12, retrieved on 08/07/2026.

How much nitrate is in the drinking water in Valangin?

EVN Wasser GesmbH publishes a nitrate value of 14 mg/l for the supply zone 2042, Großsnondorf. The statutory parametric value is 50 mg/l; the measured value represents 28 % of the parametric value. Basis: 2026-02-12, retrieved on 08/07/2026.

Who supplies the drinking water in Valangin?

EVN Wasser GesmbH. The values shown here come from the supply zone 2042, Großsnondorf and apply to the water the supplier delivers. What happens between the building connection and the tap — in old lead pipes, for example — is not covered by these analyses; information on that is provided by owners, the health authority or an examination by an accredited laboratory.

These values are more than a year old. The most recent analysis the water supplier has published for this zone dates from 31/12/2024. We have no newer values — which is why we show the latest available ones rather than none at all. They say nothing about how the water has changed since then.
