Drinking water in Humlikon
5 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.

Wasserversorgung AndelfingenAssigned 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.

Frequently asked questions about drinking water in Humlikon
- How hard is the water in Humlikon?
- Wasserversorgung Andelfingen publishes a total hardness of 39.95 °fH for the supply zone Ortsteil Adlikon — that corresponds to 22.4 °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 Humlikon?
- Wasserversorgung Andelfingen publishes a nitrate value of 8.55 mg/l for the supply zone Ortsteil Adlikon. The statutory parametric value is 40 mg/l; the measured value represents 21 % of the parametric value. Basis: 2024, retrieved on 07/08/2026.
- Who supplies the drinking water in Humlikon?
- Wasserversorgung Andelfingen. The values shown here come from the supply zone Ortsteil Adlikon 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.
