Drinking water in Feldbach, Riegersburg
4 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.
Versorgungszone I
RiegersburgAssigned 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 Feldbach, Riegersburg
- How hard is the water in Feldbach, Riegersburg?
- Riegersburg publishes a total hardness of 2,54 mmol/l for the supply zone Versorgungszone I — that corresponds to 14.2 °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 11/08/2026.
- How much nitrate is in the drinking water in Feldbach, Riegersburg?
- Riegersburg publishes a nitrate value of 17,7 mg/l for the supply zone Versorgungszone I. The statutory parametric value is 50 mg/l; the measured value represents 35 % of the parametric value. Basis: Publication by the water supplier, retrieved on 11/08/2026.
- Who supplies the drinking water in Feldbach, Riegersburg?
- Riegersburg. The values shown here come from the supply zone Versorgungszone I 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.
General questions — how current the data is, limit of quantification, parametric values, who is behind this site — are answered under Questions & answers.
