Drinking water in St. Ulrich im Mühlkreis
One supply zone, water supplier: Wasserversorgung des FWV Mühlviertel.
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.

Wasserversorgung des FWV MühlviertelAssigned via the water supplier — the exact supply zone boundary within the postcode is not yet linked.
These values are more than a year old. The most recent analysis the water supplier has published for this zone dates from 03/07/2024. 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.

Frequently asked questions about drinking water in St. Ulrich im Mühlkreis
- How hard is the water in St. Ulrich im Mühlkreis?
- Wasserversorgung des FWV Mühlviertel publishes a total hardness of 2.3 °dH for the supply zone Wasserversorgung des FWV Mühlviertel - Entsäuerung Unterhaag, Ablauf, unmittelbar nach UV (Probestelle Nr. 22) (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.

- How much nitrate is in the drinking water in St. Ulrich im Mühlkreis?
- Wasserversorgung des FWV Mühlviertel publishes a nitrate value of 4,0 mg/l for the supply zone Wasserversorgung des FWV Mühlviertel - Entsäuerung Unterhaag, Ablauf, unmittelbar nach UV (Probestelle Nr. 22). The statutory parametric value is 50 mg/l; the measured value represents 8 % of the parametric value. Basis: Publication by the water supplier, retrieved on 14/08/2026.
- Who supplies the drinking water in St. Ulrich im Mühlkreis?
- Wasserversorgung des FWV Mühlviertel. The values shown here come from the supply zone Wasserversorgung des FWV Mühlviertel - Entsäuerung Unterhaag, Ablauf, unmittelbar nach UV (Probestelle Nr. 22) and apply to the water the supplier delivers.
