Drinking water in Unterlangenegg
2 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.

Frequently asked questions about drinking water in Unterlangenegg
- How hard is the water in Unterlangenegg?
- Gemeinde Eriz publishes a total hardness of 23.14 °fH for the supply zone Blatter-Quelle Eriz — that corresponds to 13 °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 12/08/2026.
- How much nitrate is in the drinking water in Unterlangenegg?
- Gemeinde Eriz publishes a nitrate value of 3.69 mg/l for the supply zone Blatter-Quelle Eriz. The statutory parametric value is 40 mg/l; the measured value represents 9 % of the parametric value. Basis: Publication by the water supplier, retrieved on 12/08/2026.
- Who supplies the drinking water in Unterlangenegg?
- Gemeinde Eriz. The values shown here come from the supply zone Blatter-Quelle Eriz 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.
