Drinking water in Münster-Sarmsheim
7 supply zones — values can differ depending on the district. Below is the zone with the most documented parameters, the others collapsed underneath. To determine the exact match, look up the postcode.
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 - Übergabestelle HB Dorsheim, (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.

Frequently asked questions about drinking water in Münster-Sarmsheim
- How hard is the water in Münster-Sarmsheim?
- TWIST RLP - Übergabestelle HB Dorsheim, (WW), TW publishes a total hardness of 1.98 mmol/l for the supply zone Übergabestelle HB Dorsheim, (WW), TW — that corresponds to 11.1 °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 Münster-Sarmsheim?
- TWIST RLP - Übergabestelle HB Dorsheim, (WW), TW publishes a nitrate value of 27 mg/L for the supply zone Übergabestelle HB Dorsheim, (WW), TW. The statutory parametric value is 50 mg/l; the measured value represents 54 % of the parametric value. Basis: Publication by the water supplier, retrieved on 13/07/2026.
- Are PFAS detectable in the drinking water in Münster-Sarmsheim?
- TWIST RLP - Übergabestelle HB Dorsheim, (WW), TW publishes for the supply zone Übergabestelle HB Dorsheim, (WW), TW a sum value PFAS-20 of 0.016 µg/L. The statutory parametric value is 0.1 µg/l; the measured value represents 16 % 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 Münster-Sarmsheim?
- TWIST RLP - Übergabestelle HB Dorsheim, (WW), TW. The values shown here come from the supply zone Übergabestelle HB Dorsheim, (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.
