Drinking water in Weilbach
One supply zone, water supplier: Wasserversorger Weilbach.
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.

Frequently asked questions about drinking water in Weilbach
- How hard is the water in Weilbach?
- Wasserversorger Weilbach publishes a total hardness of 10.6 °dH for the supply zone Weilbach (hardness range mittel). 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: 2025, retrieved on 14/07/2026.
- How much nitrate is in the drinking water in Weilbach?
- Wasserversorger Weilbach publishes a nitrate value of 14,5 mg/l for the supply zone Weilbach. The statutory parametric value is 50 mg/l; the measured value represents 29 % of the parametric value. Basis: 2025, retrieved on 14/07/2026.
- Who supplies the drinking water in Weilbach?
- Wasserversorger Weilbach. The values shown here come from the supply zone Weilbach 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.
