Drinking water in Mechernich
12 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.

These values are more than a year old. The most recent analysis the water supplier has published for this zone dates from 31/12/2019. We have no newer values — which is why we show the latest available ones rather than none at all. They say nothing about how the water has changed since then.

Frequently asked questions about drinking water in Mechernich
- How hard is the water in Mechernich?
- Verbandswasserwerk GmbH publishes a total hardness of 3,86 mmol/l for the supply zone Entnahmestelle: HB Lommersum, Behälterausgang, Probenahmehahn (Probenahmeort: 53919 Weilerswist-Lommersum, Derkumerstraße, HB) — that corresponds to 21.6 °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: 03.11.2025 (Digital signiert), retrieved on 27/07/2026.
- How much nitrate is in the drinking water in Mechernich?
- Verbandswasserwerk GmbH publishes a nitrate value of 6,2 mg/l for the supply zone Entnahmestelle: HB Lommersum, Behälterausgang, Probenahmehahn (Probenahmeort: 53919 Weilerswist-Lommersum, Derkumerstraße, HB). The statutory parametric value is 50 mg/l; the measured value represents 12 % of the parametric value. Basis: 03.11.2025 (Digital signiert), retrieved on 27/07/2026.
