Drinking water in 68723
For this postcode the responsible water supplier publishes several supply zones. Which of them serves an individual address is not published — below are the values of the zone with the most documented parameters, the remaining 2 underneath.
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.

Frequent questions about postcode 68723
- How hard is the water in Postcode 68723?
- Zweckverband Wasserversorgung Kurpfalz (ZWK) publishes a total hardness of 17.9 °dH for the supply zone Wasserwerk Schwetzinger Hardt (hardness range hart). 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: 21.05.2026, retrieved on 11/07/2026.
- How much nitrate is in the drinking water in Postcode 68723?
- Zweckverband Wasserversorgung Kurpfalz (ZWK) publishes a nitrate value of 1,0 mg/l for the supply zone Wasserwerk Schwetzinger Hardt. The statutory parametric value is 50 mg/l; the measured value represents 2 % of the parametric value. Basis: 21.05.2026, retrieved on 11/07/2026.
- Are PFAS detectable in the drinking water in Postcode 68723?
- Zweckverband Wasserversorgung Kurpfalz (ZWK) publishes for the supply zone Wasserwerk Schwetzinger Hardt a sum value PFAS-20 below the limit of quantification (entry in the report: "<0,005 µg/l"). This is not to be read as "PFAS-free": below the limit of quantification, the measurement cannot make any statement. The statutory parametric value is 0.1 µg/l; the measured value lies below it and cannot be specified more precisely below the limit of quantification. For the sum of the 20 individual substances, this parametric value has applied since 12/01/2026. Basis: 21.05.2026, retrieved on 11/07/2026.
- Who supplies the drinking water in Postcode 68723?
- Zweckverband Wasserversorgung Kurpfalz (ZWK). The values shown here come from the supply zone Wasserwerk Schwetzinger Hardt 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.
