Drinking water in 21423
For this postcode the responsible water supplier 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 1 underneath.
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.

| Trifluoroacetic acid (TFA) | < 0.0005 µg/l below limit of quantification | 60 µg/l UBA guide value | < < 0.1 % * | Single value · Wasserwerk 24 (Ort 193) |
* 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 21423
- How hard is the water in Postcode 21423?
- handeloh publishes a total hardness of 6.8 °dH for the supply zone Wasserwerk 24 (Ort 193) (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: Publication by the water supplier, retrieved on 25/07/2026.
- How much nitrate is in the drinking water in Postcode 21423?
- handeloh publishes a nitrate value of < 0.5 mg/l for the supply zone Wasserwerk 24 (Ort 193). The statutory parametric value is 50 mg/l; the measured value lies below it and cannot be specified more precisely below the limit of quantification. Basis: Publication by the water supplier, retrieved on 25/07/2026.
- Who supplies the drinking water in Postcode 21423?
- handeloh. The values shown here come from the supply zone Wasserwerk 24 (Ort 193) 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.
