Drinking water in Bad Hersfeld, Ludwigsau
One supply zone, water supplier: Stadtwerke Bad Hersfeld GmbH (Bad Hersfeld); Gemeinde Ludwigsau (eigene kommunale Wasserversorgung).
How to read the share of the parametric value
12 % Share of the parametric value. The proportion of the permitted maximum that the measured value uses — here 12 %, so just over an eighth.
< 10 % * Below the limit of quantification. The substance was not detectable. The mark shows where the detection limit lies relative to the parametric value — the actual share of the parametric value is below that.
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 18/02/2025. 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 Bad Hersfeld, Ludwigsau
- How hard is the water in Bad Hersfeld, Ludwigsau?
- Stadtwerke Bad Hersfeld GmbH (Bad Hersfeld); Gemeinde Ludwigsau (eigene kommunale Wasserversorgung) publishes a total hardness of 13.2 °dH for the supply zone Wasserwerk Geistal, Trinkwasserausgang (hardness range mittel). 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.
