Drinking water in 27726
For this postcode Wasser- und Abwasserverband Osterholz (WAV Osterholz); Endverteilung in den Kernorten durch Osterholzer Stadtwerke GmbH & Co. KG publishes several supply zones. Which of them serves an individual address is not published — below are the values of the zone with the most documented parameters, the remaining 4 underneath.
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.

* 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.

* 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.

* 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.

Frequent questions about postcode 27726
- How hard is the water in Postcode 27726?
- Wasser- und Abwasserverband Osterholz (WAV Osterholz); Endverteilung in den Kernorten durch Osterholzer Stadtwerke GmbH & Co. KG publishes a total hardness of 7.5 °dH for the supply zone ON Neuenkirchen-Schwanewede (GS, Reinwasser) und WW Siedbruch (Reinwasser) (hardness range soft). 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: 11.06.2026, retrieved on 11/07/2026.
- How much nitrate is in the drinking water in Postcode 27726?
- Wasser- und Abwasserverband Osterholz (WAV Osterholz); Endverteilung in den Kernorten durch Osterholzer Stadtwerke GmbH & Co. KG publishes a nitrate value of 6 mg/l for the supply zone ON Neuenkirchen-Schwanewede (GS, Reinwasser) und WW Siedbruch (Reinwasser). The statutory parametric value is 50 mg/l; the measured value represents 12 % of the parametric value. Basis: 11.06.2026, retrieved on 11/07/2026.
- Are PFAS detectable in the drinking water in Postcode 27726?
- Wasser- und Abwasserverband Osterholz (WAV Osterholz); Endverteilung in den Kernorten durch Osterholzer Stadtwerke GmbH & Co. KG publishes for the supply zone ON Neuenkirchen-Schwanewede (GS, Reinwasser) und WW Siedbruch (Reinwasser) a sum value PFAS-20 below the limit of quantification (entry in the report: "<0,030 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: 11.06.2026, retrieved on 11/07/2026.
- Who supplies the drinking water in Postcode 27726?
- Wasser- und Abwasserverband Osterholz (WAV Osterholz); Endverteilung in den Kernorten durch Osterholzer Stadtwerke GmbH & Co. KG. The values shown here come from the supply zone ON Neuenkirchen-Schwanewede (GS, Reinwasser) und WW Siedbruch (Reinwasser) 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.
