How hard is the water in Aalen?

Stadtwerke Aalen publishes a total hardness of 17 °dH for the supply zone Eigenwasser Niederzone Aalen (hardness range hart). 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: Publication by the water supplier, retrieved on 11/07/2026.

How much nitrate is in the drinking water in Aalen?

Stadtwerke Aalen publishes a nitrate value of 13,1 mg/L for the supply zone Eigenwasser Niederzone Aalen. The statutory parametric value is 50 mg/l; the measured value represents 26 % of the parametric value. Basis: Publication by the water supplier, retrieved on 11/07/2026.

Who supplies the drinking water in Aalen?

Stadtwerke Aalen. The values shown here come from the supply zone Eigenwasser Niederzone Aalen 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.

No date is given for these values. The water supplier publishes the analysis without a sampling date and without a report date. When the water was examined is not apparent from the source — we do not add a date and we do not estimate one. What is stated is therefore only when we retrieved the document.
