Drinking water in Ottenhöfen im Schwarzwald

One supply zone, water supplier: Gemeinde Ottenhöfen im Schwarzwald.

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.

Gemeinde Ottenhöfen im Schwarzwald

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 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 Ottenhöfen im Schwarzwald

How hard is the water in Ottenhöfen im Schwarzwald?
Gemeinde Ottenhöfen im Schwarzwald publishes the hardness range 0,7 for the supply zone Versorgungsbereich 1 (Ottenhöfen und Furschenbach). 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: Stand: Oktober 2024, retrieved on 08/08/2026.
How much nitrate is in the drinking water in Ottenhöfen im Schwarzwald?
Gemeinde Ottenhöfen im Schwarzwald publishes a nitrate value of 4,53 mg/L for the supply zone Versorgungsbereich 1 (Ottenhöfen und Furschenbach). The statutory parametric value is 50 mg/l; the measured value represents 9 % of the parametric value. Basis: Stand: Oktober 2024, retrieved on 08/08/2026.
Who supplies the drinking water in Ottenhöfen im Schwarzwald?
