Drinking water in Barnstorf, Eydelstedt, Drentwede

11 supply zones — values can differ depending on the district. Below is the zone with the most documented parameters, the others collapsed underneath. To determine the exact match, look up the postcode.

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.

For trifluoroacetic acid (TFA), the German Drinking Water Ordinance does not specify a parametric value. The comparison is therefore made with the guide value of 60 µg/l issued by the Umweltbundesamt, which has replaced the earlier health-related guidance value of 3 µg/l. A guide value is not a legal maximum but a health-related classification.

An exceedance of a parametric value does not automatically mean a health risk; the statutory parametric values include safety margins. Assessment and any measures are the responsibility of the competent health authority of the respective country.

* 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.

For trifluoroacetic acid (TFA), the German Drinking Water Ordinance does not specify a parametric value. The comparison is therefore made with the guide value of 60 µg/l issued by the Umweltbundesamt, which has replaced the earlier health-related guidance value of 3 µg/l. A guide value is not a legal maximum but a health-related classification.

Frequently asked questions about drinking water in Barnstorf, Eydelstedt, Drentwede

How hard is the water in Barnstorf, Eydelstedt, Drentwede?
OOWV (Oldenburgisch-Ostfriesischer Wasserverband) publishes a total hardness of 7 °dH for the supply zone Großenkneten (hardness range weich). 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 11/07/2026.
How much nitrate is in the drinking water in Barnstorf, Eydelstedt, Drentwede?
OOWV (Oldenburgisch-Ostfriesischer Wasserverband) publishes a nitrate value of 5,2 mg/l for the supply zone Großenkneten. The statutory parametric value is 50 mg/l; the measured value represents 10 % of the parametric value. Basis: Publication by the water supplier, retrieved on 11/07/2026.
Are PFAS detectable in the drinking water in Barnstorf, Eydelstedt, Drentwede?
OOWV (Oldenburgisch-Ostfriesischer Wasserverband) publishes for the supply zone Großenkneten a sum value PFAS-20 below the limit of quantification (entry in the report: "<0,020 µg/l"). 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 11/07/2026.
Who supplies the drinking water in Barnstorf, Eydelstedt, Drentwede?
OOWV (Oldenburgisch-Ostfriesischer Wasserverband). The values shown here come from the supply zone Großenkneten 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.

General questions — how current the data is, limit of quantification, parametric values, who is behind this site — are answered under Questions & answers.
