Drinking water in Marbach an der Donau
3 supply zones — values can differ depending on the district. Below is the zone with the most documented parameters, the others collapsed underneath. To determine the exact match, look up the postcode.
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.

These values are more than a year old. The most recent analysis the water supplier has published for this zone dates from 18/03/2025. 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.

Frequently asked questions about drinking water in Marbach an der Donau
- How hard is the water in Marbach an der Donau?
- Gemeindeverband WVA Marbach Klein Pöchlarn publishes a total hardness of 2,87 mmol/l for the supply zone N280705R3 - WVA Gemeindeverband Marbach - Kl. Pöchlarn - Brunnen Hagsdorf - Probenahmehahn, Verbandsleitung — that corresponds to 16.1 °dH. 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.
