Drinking water in 33142
One supply zone, water supplier: Wasserwerk Stadt Büren.
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.

Wasserwerk Stadt BürenAssigned via the water supplier — the exact supply zone boundary within the postcode is not yet linked.
No date is given for these values. The water supplier publishes the analysis without a sampling date and without a report date. When the water was examined is not apparent from the source — we do not add a date and we do not estimate one. What is stated is therefore only when we retrieved the document.
| Parameter | Value | Parametric value | Share of the parametric value | Reference |
|---|---|---|---|---|
| Nitrate | 7 mg/l | 50 mg/l | 14 % | Mean |
| Lead | <0,0010 mg/l below limit of quantification | 10 µg/l | < 10 % * | Mean |
| Sulphate | 32 mg/l | 250 mg/l | 13 % | Mean |
| Sodium | 6,47 mg/l | 200 mg/l | 3 % | Mean |
* 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.

Frequent questions about postcode 33142
- How hard is the water in Postcode 33142?
- Wasserwerk Stadt Büren publishes a total hardness of 9.5 °dH for the supply zone Aabach (hardness range mittel). 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: Publication by the water supplier, retrieved on 11/07/2026.
- How much nitrate is in the drinking water in Postcode 33142?
- Wasserwerk Stadt Büren publishes a nitrate value of 7 mg/l for the supply zone Aabach. The statutory parametric value is 50 mg/l; the measured value represents 14 % of the parametric value. Basis: Publication by the water supplier, retrieved on 11/07/2026.
- Who supplies the drinking water in Postcode 33142?
- Wasserwerk Stadt Büren. The values shown here come from the supply zone Aabach 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.
