Drinking water in 4101 (Austria)
One supply zone, water supplier: Fernwasserverband Mühlviertel.
The values come from the Austrian drinking water database, to which water suppliers report voluntarily. In each case the highest value of the published range is given.
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.

Frequent questions about postcode 4101
- How hard is the water in Postcode 4101?
- Fernwasserverband Mühlviertel publishes a total hardness of 6.4 °dH for the supply zone at-herzogsdorf gesamt. Hardness indicates how much calcium and magnesium are dissolved in the water. It is not a quality assessment: there is no parametric value for hardness. Basis: Publication by the water supplier, retrieved on 14/08/2026.
- How much nitrate is in the drinking water in Postcode 4101?
- Fernwasserverband Mühlviertel publishes a nitrate value of 11,00 mg/l for the supply zone at-herzogsdorf gesamt. The statutory parametric value is 50 mg/l; the measured value represents 22 % of the parametric value. Basis: Publication by the water supplier, retrieved on 14/08/2026.
- Who supplies the drinking water in Postcode 4101?
- Fernwasserverband Mühlviertel. The values shown here come from the supply zone at-herzogsdorf gesamt 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.
