Drinking water in 34225
For this postcode Stadtwerke Baunatal (Eigenbetrieb der Stadt Baunatal) publishes several supply zones. Which of them serves an individual address is not published — below are the values of the zone with the most documented parameters, the remaining 9 underneath.
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 34225
- Are PFAS detectable in the drinking water in Postcode 34225?
- Stadtwerke Baunatal (Eigenbetrieb der Stadt Baunatal) states for the supply zone Baunatal - Altenbauna, Entnahmeort Bornhagen 2, Entnahmestelle Kindergarten Birkenallee that the sum PFAS-20 was not detectable (entry in the report: "n. n."). This is not to be read as "PFAS-free": below the limit of quantification, the measurement cannot make any statement. The statutory parametric value is 0.1 µg/l; the measured value lies below it and cannot be specified more precisely below the limit of quantification. For the sum of the 20 individual substances, this parametric value has applied since 12/01/2026. Basis: 22.05.2026, retrieved on 11/07/2026.
- Who supplies the drinking water in Postcode 34225?
- Stadtwerke Baunatal (Eigenbetrieb der Stadt Baunatal). The values shown here come from the supply zone Baunatal - Altenbauna, Entnahmeort Bornhagen 2, Entnahmestelle Kindergarten Birkenallee 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.
