Drinking water in Gröbming, Michaelerberg-Pruggern, Mitterberg-Sankt Martin
One supply zone, water supplier: Wv Bergdietikon.
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.

An exceedance of a parametric value does not automatically mean a health risk; the statutory parametric values include safety margins. Assessment and any measures are the responsibility of the competent health authority of the respective country.

Chemical parameters (2)
| Parameter | Value | Parametric value | Share of the parametric value | Reference |
|---|---|---|---|---|
| Fluoride | < 0.1 mg/l below limit of quantification | 1.5 mg/l | < 7 % * | Mean · Bergdietikon |
| Nitrate | 14.7 mg/l | 40 mg/l | 37 % | Mean · Bergdietikon |
* Value below the limit of quantification: the actual share of the parametric value is not known; it lies somewhere below the stated upper bound. The marker shows where the limit of quantification of the measurement lies relative to the parametric value.

Frequently asked questions about drinking water in Gröbming, Michaelerberg-Pruggern, Mitterberg-Sankt Martin
- How hard is the water in Gröbming, Michaelerberg-Pruggern, Mitterberg-Sankt Martin?
- Wv Bergdietikon publishes a total hardness of 32.8 °fH for the supply zone Bergdietikon — that corresponds to 18.4 °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: 2025, retrieved on 07/08/2026.
- How much nitrate is in the drinking water in Gröbming, Michaelerberg-Pruggern, Mitterberg-Sankt Martin?
- Wv Bergdietikon publishes a nitrate value of 14.7 mg/l for the supply zone Bergdietikon. The statutory parametric value is 40 mg/l; the measured value represents 37 % of the parametric value. Basis: 2025, retrieved on 07/08/2026.
- Who supplies the drinking water in Gröbming, Michaelerberg-Pruggern, Mitterberg-Sankt Martin?
- Wv Bergdietikon. The values shown here come from the supply zone Bergdietikon 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.
