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.

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.

Frequently asked questions about drinking water in Koblenz
- How hard is the water in Koblenz?
- TWIST RLP - WGA Kaltenengers (WW), TW publishes a total hardness of 2.44 mmol/l for the supply zone WGA Kaltenengers (WW), TW — that corresponds to 13.7 °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 Koblenz?
- TWIST RLP - WGA Kaltenengers (WW), TW publishes a nitrate value of 11 mg/L for the supply zone WGA Kaltenengers (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 Koblenz?
- TWIST RLP - WGA Kaltenengers (WW), TW publishes for the supply zone WGA Kaltenengers (WW), TW a sum value PFAS-20 of 0.01 µg/L. The statutory parametric value is 0.1 µg/l; the measured value represents 10 % 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 Koblenz?
- TWIST RLP - WGA Kaltenengers (WW), TW. The values shown here come from the supply zone WGA Kaltenengers (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.
