Drinking water in 67278
One supply zone, water supplier: TWIST RLP - ÜGS Mertesheim (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.

TWIST RLP - ÜGS Mertesheim (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 67278
- How hard is the water in Postcode 67278?
- TWIST RLP - ÜGS Mertesheim (WW), TW publishes a total hardness of 2.5 mmol/l for the supply zone ÜGS Mertesheim (WW), TW — that corresponds to 14 °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 67278?
- TWIST RLP - ÜGS Mertesheim (WW), TW publishes a nitrate value of 21 mg/L for the supply zone ÜGS Mertesheim (WW), TW. The statutory parametric value is 50 mg/l; the measured value represents 42 % of the parametric value. Basis: Publication by the water supplier, retrieved on 13/07/2026.
- Are PFAS detectable in the drinking water in Postcode 67278?
- TWIST RLP - ÜGS Mertesheim (WW), TW publishes for the supply zone ÜGS Mertesheim (WW), TW a sum value PFAS-20 below the limit of quantification (entry in the report: "< 0.001 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: Publication by the water supplier, retrieved on 13/07/2026.
- Who supplies the drinking water in Postcode 67278?
- TWIST RLP - ÜGS Mertesheim (WW), TW. The values shown here come from the supply zone ÜGS Mertesheim (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.
