Drinking water in Nickenich
One supply zone, water supplier: TWIST RLP - Wasserwerk Kruft (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 - Wasserwerk Kruft (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 Nickenich
- How hard is the water in Nickenich?
- TWIST RLP - Wasserwerk Kruft (WW), TW publishes a total hardness of 1.92 mmol/l for the supply zone Wasserwerk Kruft (WW), TW — that corresponds to 10.8 °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 Nickenich?
- TWIST RLP - Wasserwerk Kruft (WW), TW publishes a nitrate value of 45 mg/L for the supply zone Wasserwerk Kruft (WW), TW. The statutory parametric value is 50 mg/l; the measured value represents 90 % of the parametric value. Basis: Publication by the water supplier, retrieved on 13/07/2026.
