Drinking water in Eyholz, Visp
One supply zone, water supplier: Wasserversorgung Visp / Eyholz.
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 Visp / EyholzAssigned 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.

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.

- How hard is the water in Eyholz, Visp?
- Wasserversorgung Visp / Eyholz publishes a total hardness of 13.7 °fH for the supply zone Visp und Eyholz — that corresponds to 7.7 °dH.

- Wasserversorgung Visp / Eyholz publishes a nitrate value of 2.1 mg/l for the supply zone Visp und Eyholz. The statutory parametric value is 40 mg/l; the measured value represents 5 % of the parametric value. Basis: 2024, retrieved on 07/08/2026.
