Drinking water in Arriach
12 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.
9542 Münchwilen TG
Genossenschaft EW MünchwilenAssigned 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 31/12/2023. 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.

These values are more than a year old. The most recent analysis the water supplier has published for this zone dates from 02/04/2025. 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.

Frequently asked questions about drinking water in Arriach
- How hard is the water in Arriach?
- Genossenschaft EW Münchwilen publishes a total hardness of 33.4 °fH for the supply zone 9542 Münchwilen TG — that corresponds to 18.7 °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: 2023, retrieved on 07/08/2026.
- How much nitrate is in the drinking water in Arriach?
- Genossenschaft EW Münchwilen publishes a nitrate value of 15 mg/l for the supply zone 9542 Münchwilen TG. The statutory parametric value is 40 mg/l; the measured value represents 38 % of the parametric value. Basis: 2023, retrieved on 07/08/2026.
- Who supplies the drinking water in Arriach?
- Genossenschaft EW Münchwilen. The values shown here come from the supply zone 9542 Münchwilen TG 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.
