Drinking water in Schwarmstedt u.a.
3 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
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) | 0,000449 mg/l | 60 µg/l UBA guide value | 0.7 % | Mean |
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 Schwarmstedt u.a.
- How hard is the water in Schwarmstedt u.a.?
- Wasserverband Nordhannover (WVN) publishes a total hardness of 2,1 mmol/l for the supply zone burgwedel gesamt — that corresponds to 11.8 °dH. 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: Februar 2026, retrieved on 11/07/2026.
- How much nitrate is in the drinking water in Schwarmstedt u.a.?
- Wasserverband Nordhannover (WVN) publishes a nitrate value of 2,2 mg/l for the supply zone burgwedel gesamt. The statutory parametric value is 50 mg/l; the measured value represents 4 % of the parametric value. Basis: Februar 2026, retrieved on 11/07/2026.
- Who supplies the drinking water in Schwarmstedt u.a.?
- Wasserverband Nordhannover (WVN). The values shown here come from the supply zone burgwedel gesamt 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.
