Drinking water in Grebenau
7 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 04/12/2024. 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 Grebenau
- Who supplies the drinking water in Grebenau?
- Grebenau. The values shown here come from the supply zone Bieben ON 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.
General questions — how current the data is, limit of quantification, parametric values, who is behind this site — are answered under Questions & answers.
