Drinking water in 56746
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.

TWIST RLP - HB Engelner Kopf (WW), TWAssigned 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.

Frequent questions about postcode 56746
- How hard is the water in Postcode 56746?
- TWIST RLP - HB Engelner Kopf (WW), TW publishes a total hardness of 1.28 mmol/l for the supply zone HB Engelner Kopf (WW), TW — that corresponds to 7.2 °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: Publication by the water supplier, retrieved on 13/07/2026.
- How much nitrate is in the drinking water in Postcode 56746?
- TWIST RLP - HB Engelner Kopf (WW), TW publishes a nitrate value of 32 mg/L for the supply zone HB Engelner Kopf (WW), TW. The statutory parametric value is 50 mg/l; the measured value represents 64 % of the parametric value. Basis: Publication by the water supplier, retrieved on 13/07/2026.
- Are PFAS detectable in the drinking water in Postcode 56746?
- TWIST RLP - HB Engelner Kopf (WW), TW publishes for the supply zone HB Engelner Kopf (WW), TW a sum value PFAS-20 of 0.002 µg/L. The statutory parametric value is 0.1 µg/l; the measured value represents 2 % of the parametric value. For the sum of the 20 individual substances, this parametric value has applied since 12/01/2026. Basis: Publication by the water supplier, retrieved on 13/07/2026.
- Who supplies the drinking water in Postcode 56746?
- TWIST RLP - HB Engelner Kopf (WW), TW. The values shown here come from the supply zone HB Engelner Kopf (WW), TW 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.
