Drinking water in Owingen
One supply zone, water supplier: Bodensee-Wasserversorgung.
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.

Frequently asked questions about drinking water in Owingen
- How hard is the water in Owingen?
- Bodensee-Wasserversorgung publishes a total hardness of 22.3 °dH for the supply zone Owingen, Kindergarten Guggenbühl (hardness range hart). 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: Publication by the water supplier, retrieved on 27/07/2026.
- How much nitrate is in the drinking water in Owingen?
- Bodensee-Wasserversorgung publishes a nitrate value of 12 mg/L for the supply zone Owingen, Kindergarten Guggenbühl. The statutory parametric value is 50 mg/l; the measured value represents 24 % of the parametric value. Basis: Publication by the water supplier, retrieved on 27/07/2026.
- Are PFAS detectable in the drinking water in Owingen?
- Bodensee-Wasserversorgung states for the supply zone Owingen, Kindergarten Guggenbühl that the sum PFAS-20 was not detectable (entry in the report: "n.n."). This is not to be read as "PFAS-free": below the limit of quantification, the measurement cannot make any statement. The statutory parametric value is 0.1 µg/l; the measured value lies below it and cannot be specified more precisely below the limit of quantification. For the sum of the 20 individual substances, this parametric value has applied since 12/01/2026. Basis: Publication by the water supplier, retrieved on 27/07/2026.
- Who supplies the drinking water in Owingen?
- Bodensee-Wasserversorgung. The values shown here come from the supply zone Owingen, Kindergarten Guggenbühl 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.
