Drinking water in Speyer
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.

Frequently asked questions about drinking water in Speyer
- How much nitrate is in the drinking water in Speyer?
- Stadtwerke Speyer GmbH publishes a nitrate value of <1 mg/l for the supply zone speyer gesamt. 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: Stand 10/2025, retrieved on 11/07/2026.
- Who supplies the drinking water in Speyer?
- Stadtwerke Speyer GmbH. The values shown here come from the supply zone speyer gesamt 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.
