Drinking water in 32457
One supply zone, water supplier: Stadtwerke Porta Westfalica GmbH.
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.

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.

* 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.
PFAS (1)
| Parameter | Value | Parametric value | Share of the parametric value | Reference |
|---|---|---|---|---|
| Trifluoroacetic acid (TFA) | 0.00169 mg/l | 60 µg/l UBA guide value | 3 % | Single 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.

Frequent questions about postcode 32457
- How hard is the water in Postcode 32457?
- Stadtwerke Porta Westfalica GmbH publishes a total hardness of 3.3 mmol/l for the supply zone Grundwasserwerk Veltheim, Sprengelweg, 32457 Porta Westfalica, Reinwasserbehälter, Entnahmehahn — that corresponds to 18.5 °dH. 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: 21.06.24, retrieved on 11/07/2026.
- How much nitrate is in the drinking water in Postcode 32457?
- Stadtwerke Porta Westfalica GmbH publishes a nitrate value of 25 mg/l for the supply zone Grundwasserwerk Veltheim, Sprengelweg, 32457 Porta Westfalica, Reinwasserbehälter, Entnahmehahn. The statutory parametric value is 50 mg/l; the measured value represents 50 % of the parametric value. Basis: 21.06.24, retrieved on 11/07/2026.
