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

Gemeinde Ottenhöfen im SchwarzwaldAssigned 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.
| Parameter | Value | Parametric value | Share of the parametric value | Reference |
|---|---|---|---|---|
| Nitrate | 4,53 mg/L | 50 mg/l | 9 % | Single value |
| Lead | <0,001 mg/L below limit of quantification | 10 µg/l | < 10 % * | Single value |
| Sodium | 1,6 mg/L | 200 mg/l | 0.8 % | Single value |
* 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 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?
- Gemeinde Ottenhöfen im Schwarzwald. The values shown here come from the supply zone Versorgungsbereich 1 (Ottenhöfen und Furschenbach) 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.
