How hard is the water in Itter?

Gemeinde Itter publishes a total hardness of 12.2 °dH for the supply zone 6305, Volksschule, Dorfplatz 3, WB 2. Klasse (hardness range medium). 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: 2023-07-19, retrieved on 08/08/2026.

How much nitrate is in the drinking water in Itter?

Gemeinde Itter publishes a nitrate value of 4,5 mg/l for the supply zone 6305, Volksschule, Dorfplatz 3, WB 2. Klasse. The statutory parametric value is 50 mg/l; the measured value represents 9 % of the parametric value. Basis: 2023-07-19, retrieved on 08/08/2026.

How to read the share of the parametric value

12 % Share of the parametric value. The proportion of the permitted maximum that the measured value uses — here 12 %, so just over an eighth.

< 10 % * Below the limit of quantification. The substance was not detectable. The mark shows where the detection limit lies relative to the parametric value — the actual share of the parametric value is below that.

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.

Assigned 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 19/07/2023. 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.
