Drinking water in Dietlikon
One supply zone, water supplier: Wasserversorgung Dietlikon.
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.

Wasserversorgung DietlikonAssigned 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 31/12/2024. 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.

| Chlorothalonil metabolite R471811 | 0.16 µg/l | 0.1 µg/l | 160 % Mean above the parametric value | Mean · Wasserversorgung Dietlikon |
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 Dietlikon
- How hard is the water in Dietlikon?
- Wasserversorgung Dietlikon publishes a total hardness of 31.5 °fH for the supply zone Wasserversorgung Dietlikon — 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: 2024, retrieved on 07/08/2026.
- How much nitrate is in the drinking water in Dietlikon?
- Wasserversorgung Dietlikon publishes a nitrate value of 12.56 mg/l for the supply zone Wasserversorgung Dietlikon. The statutory parametric value is 40 mg/l; the measured value represents 31 % of the parametric value. Basis: 2024, retrieved on 07/08/2026.
- Who supplies the drinking water in Dietlikon?
- Wasserversorgung Dietlikon. The values shown here come from the supply zone Wasserversorgung Dietlikon 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.
