Drinking water in 4202 (Austria)
One supply zone, water supplier: Wasserverband Fernwasserversorgung 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.

Wasserverband Fernwasserversorgung 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 04/06/2025. 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.
