Drinking water in 4731 (Austria)
For this postcode the responsible water supplier 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 2 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
12 % Share of the parametric value. The proportion of the permitted maximum that the measured value uses — here 12 %, so just over an eighth.
< 10 % * Below the limit of quantification. The substance was not detectable. The mark shows where the detection limit lies relative to the parametric value — the actual share of the parametric value is below that.
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.
WV Gemeinde Waizenkirchen - Netzprobe Freibad nach Enteisenung, Entnahmestelle: Auslauf Bademeisterraum
Marktgemeinde Waizenkirchen (WV Gemeinde Waizenkirchen)Assigned via the water supplier — the exact supply zone boundary within the postcode is not yet linked.
These values are more than a year old. The most recent analysis the water supplier has published for this zone dates from 15/07/2025. 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.

Frequent questions about postcode 4731
- How hard is the water in Postcode 4731?
- Marktgemeinde Waizenkirchen (WV Gemeinde Waizenkirchen) publishes a total hardness of 2,64 mmol/l for the supply zone WV Gemeinde Waizenkirchen - Netzprobe Freibad nach Enteisenung, Entnahmestelle: Auslauf Bademeisterraum — that corresponds to 14.8 °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: 29.07.2025, retrieved on 14/08/2026.
- How much nitrate is in the drinking water in Postcode 4731?
- Marktgemeinde Waizenkirchen (WV Gemeinde Waizenkirchen) publishes a nitrate value of 4,29 mg/l for the supply zone WV Gemeinde Waizenkirchen - Netzprobe Freibad nach Enteisenung, Entnahmestelle: Auslauf Bademeisterraum. The statutory parametric value is 50 mg/l; the measured value represents 9 % of the parametric value. Basis: 29.07.2025, retrieved on 14/08/2026.
- Are PFAS detectable in the drinking water in Postcode 4731?
- Marktgemeinde Waizenkirchen (WV Gemeinde Waizenkirchen) publishes for the supply zone WV Gemeinde Waizenkirchen - Netzprobe Freibad nach Enteisenung, Entnahmestelle: Auslauf Bademeisterraum a sum value PFAS-20 below the limit of quantification (entry in the report: "<0,0010 µg/l"). This is not to be read as "PFAS-free": below the limit of quantification, the measurement cannot make any statement. The statutory parametric value is 0.1 µg/l; the measured value lies below it and cannot be specified more precisely below the limit of quantification. For the sum of the 20 individual substances, this parametric value has applied since 12/01/2026. Basis: 29.07.2025, retrieved on 14/08/2026.
- Who supplies the drinking water in Postcode 4731?
- Marktgemeinde Waizenkirchen (WV Gemeinde Waizenkirchen). The values shown here come from the supply zone WV Gemeinde Waizenkirchen - Netzprobe Freibad nach Enteisenung, Entnahmestelle: Auslauf Bademeisterraum 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.
