Drinking water in 22087
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 8 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.

| Trifluoroacetic acid (TFA) | < 0,25 µg/l below limit of quantification | 60 µg/l UBA guide value | < 0.4 % * | Mean · Source [4] |
* 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 22087
- How hard is the water in Postcode 22087?
- HAMBURG WASSER (Hamburger Wasserwerke GmbH) publishes a total hardness of 12.5 °dH for the supply zone Großhansdorf (hardness range medium). 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: 29.01.2026, retrieved on 25/07/2026.
- How much nitrate is in the drinking water in Postcode 22087?
- HAMBURG WASSER (Hamburger Wasserwerke GmbH) publishes a nitrate value of 1,8 mg/l for the supply zone Großhansdorf. The statutory parametric value is 50 mg/l; the measured value represents 4 % of the parametric value. Basis: 29.01.2026, retrieved on 25/07/2026.
- Are PFAS detectable in the drinking water in Postcode 22087?
- HAMBURG WASSER (Hamburger Wasserwerke GmbH) publishes for the supply zone Großhansdorf a sum value PFAS-20 of 0 µg/l. The statutory parametric value is 0.1 µg/l; the measured value represents 0 % of the parametric value. For the sum of the 20 individual substances, this parametric value has applied since 12/01/2026. Basis: 29.01.2026, retrieved on 25/07/2026.
- Who supplies the drinking water in Postcode 22087?
- HAMBURG WASSER (Hamburger Wasserwerke GmbH). The values shown here come from the supply zone Großhansdorf 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.
