How to read the share of the parametric value
Several samples per year: for chemical parameters the mean value is given, for microbiological ones the highest measured value. There the parametric value is zero — a single finding would disappear in the average, and it is precisely that finding which is the information. Which reference applies is stated in the last column of the table.

Frequently asked questions about drinking water in Schwanstetten
- How hard is the water in Schwanstetten?
- Zweckverband zur Wasserversorgung der Schwarzachgruppe publishes a total hardness of 8.3 °dH for the supply zone Wasserwerk Großschwarzenlohe (hardness range soft). 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: August 2025, retrieved on 13/07/2026.
- How much nitrate is in the drinking water in Schwanstetten?
- Zweckverband zur Wasserversorgung der Schwarzachgruppe publishes a nitrate value of 6 mg/l for the supply zone Wasserwerk Großschwarzenlohe. The statutory parametric value is 50 mg/l; the measured value represents 12 % of the parametric value. Basis: August 2025, retrieved on 13/07/2026.
- Who supplies the drinking water in Schwanstetten?
- Zweckverband zur Wasserversorgung der Schwarzachgruppe. The values shown here come from the supply zone Wasserwerk Großschwarzenlohe 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.
