Drinking water in Salzhausen
One supply zone, water supplier: Samtgemeinde Salzhausen (WW Salzhausen).
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.
WW Salzhausen
Samtgemeinde Salzhausen (WW Salzhausen)Assigned 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 14/01/2025. 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.

* Value below the limit of quantification: the actual share of the parametric value is not known; it lies somewhere below the stated upper bound. The marker shows where the limit of quantification of the measurement lies relative to the parametric value.
For trifluoroacetic acid (TFA), the German Drinking Water Ordinance does not specify a parametric value. The comparison is therefore made with the guide value of 60 µg/l issued by the Umweltbundesamt, which has replaced the earlier health-related guidance value of 3 µg/l. A guide value is not a legal maximum but a health-related classification.

Frequently asked questions about drinking water in Salzhausen
- How hard is the water in Salzhausen?
- Samtgemeinde Salzhausen (WW Salzhausen) publishes a total hardness of 7.6 °dH for the supply zone WW Salzhausen (hardness range soft). 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. Basis: 19.02.2025, retrieved on 13/07/2026.
- How much nitrate is in the drinking water in Salzhausen?
- Samtgemeinde Salzhausen (WW Salzhausen) publishes a nitrate value of < 1,0 mg/l for the supply zone WW Salzhausen. The statutory parametric value is 50 mg/l; the measured value lies below it and cannot be specified more precisely below the limit of quantification. Basis: 19.02.2025, retrieved on 13/07/2026.
- Who supplies the drinking water in Salzhausen?
- Samtgemeinde Salzhausen (WW Salzhausen). The values shown here come from the supply zone WW Salzhausen 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.
