Drinking water in Wislikofen
8 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.

Annual means and medians are not individual measured values, but the parametric values apply per sample. If a mean lies above it, at least one individual sample was above it — the mean does not say how many, or by how much. That is why this is not reported here as an exceedance of the parametric value. What counts remains the water supplier's publication, which each row links to.

Frequently asked questions about drinking water in Wislikofen
- How hard is the water in Wislikofen?
- Gemeinde Zurzach publishes a total hardness of 31.5 °fH for the supply zone 5323 Rietheim — that corresponds to 17.6 °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: 2025, retrieved on 07/08/2026.
- How much nitrate is in the drinking water in Wislikofen?
- Gemeinde Zurzach publishes a nitrate value of 19 mg/l for the supply zone 5323 Rietheim. The statutory parametric value is 40 mg/l; the measured value represents 48 % of the parametric value. Basis: 2025, retrieved on 07/08/2026.
- Who supplies the drinking water in Wislikofen?
- Gemeinde Zurzach. The values shown here come from the supply zone 5323 Rietheim 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.
