Drinking water in 8334 (Austria)
For this postcode Riegersburg publishes several supply zones. Which of them serves an individual address is not published — below are the values of the zone with the most documented parameters, the remaining 3 underneath.
The values come from the Austrian drinking water database, to which water suppliers report voluntarily. In each case the highest value of the published range is given.
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.

Frequent questions about postcode 8334
- How hard is the water in Postcode 8334?
- Riegersburg publishes a total hardness of 2,54 mmol/l for the supply zone Versorgungszone I — that corresponds to 14.2 °dH. Hardness indicates how much calcium and magnesium are dissolved in the water. It is not a quality assessment: there is no parametric value for hardness. Basis: Publication by the water supplier, retrieved on 11/08/2026.
- How much nitrate is in the drinking water in Postcode 8334?
- 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 Postcode 8334?
- 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.
