Drinking water in Weener
One supply zone, water supplier: Wasserversorgungsverband Rheiderland.
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.

| Parameter | Value | Parametric value | Share of the parametric value | Reference |
|---|---|---|---|---|
| Nitrate | <1 mg/l below limit of quantification | 50 mg/l | < 2 % * | Single value |
| Lead | < 0,001 mg/l below limit of quantification | 10 µg/l | < 10 % * | Single value |
| Sulphate | 199 mg/l | 250 mg/l | 80 % | Single value |
| Sodium | 76 mg/l | 200 mg/l | 38 % | Single value |
* 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.

Frequently asked questions about drinking water in Weener
- How much nitrate is in the drinking water in Weener?
- Wasserversorgungsverband Rheiderland publishes a nitrate value of <1 mg/l for the supply zone Wasserwerk Weener. 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: 25.02.2026, retrieved on 11/07/2026.
- Who supplies the drinking water in Weener?
- Wasserversorgungsverband Rheiderland. The values shown here come from the supply zone Wasserwerk Weener 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.
