Drinking water in 55457
One supply zone, water supplier: TWIST RLP - PS Gensingen (WW),TW.
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.
PS Gensingen (WW),TW
TWIST RLP - PS Gensingen (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.
| Parameter | Value | Parametric value | Share of the parametric value | Reference |

| Sodium | 83.9 mg/L | 200 mg/l | 42 % | Mean · PS Gensingen (WW),TW |
* 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.
Annual means and medians are not individual measured values, but the parametric values apply per sample. If a mean lies above it, at least one individual sample was above it — the mean does not say how many, or by how much. That is why this is not reported here as an exceedance of the parametric value. What counts remains the water supplier's publication, which each row links to.

Frequent questions about postcode 55457
- How hard is the water in Postcode 55457?
- TWIST RLP - PS Gensingen (WW),TW publishes a total hardness of 2.2 mmol/l for the supply zone PS Gensingen (WW),TW — that corresponds to 12.3 °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 55457?
- TWIST RLP - PS Gensingen (WW),TW publishes a nitrate value of 10.9 mg/L for the supply zone PS Gensingen (WW),TW. The statutory parametric value is 50 mg/l; the measured value represents 22 % of the parametric value. Basis: Publication by the water supplier, retrieved on 13/07/2026.
- Are PFAS detectable in the drinking water in Postcode 55457?
- TWIST RLP - PS Gensingen (WW),TW publishes for the supply zone PS Gensingen (WW),TW a sum value PFAS-20 of 0.13 µg/L. The statutory parametric value is 0.1 µg/l — the published value lies above it. An exceedance of a parametric value does not automatically mean a health risk; the parametric values include safety margins. The competent health authority of the respective country is responsible for the assessment and any measures. 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 55457?
- TWIST RLP - PS Gensingen (WW),TW. The values shown here come from the supply zone PS Gensingen (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.
