Verified drinking-water values
Note from the test report (in the German original): Wasser und Abwasser GmbH -Boddenland- · Trinkwasseranalyse für das Versorgungsgebiet Wasserwerk Peterskreuz, Stand 29.07.2026, veröffentlicht im BDEW-Wasserportal. Die Werte wurden automatisch aus dem PDF ausgelesen und einzeln gegengeprüft; die Seite steht beim Originalwert. Laut Wasserportal liegen der Ortsmittelpunkt von Wieck und vier Prüfpunkte rund 1,5 km darum in diesem Versorgungsgebiet. Welches Wasser an einer bestimmten Adresse ankommt, sagt verbindlich der Versorger. Die Werte gelten ab Wasserwerk.
What the values mean for Wieck
- Nitrate 2.06 mg/L – about 4 % of the limit of 50 mg/L and in the unremarkable range. Boiling does not reduce nitrate.
- PFAS (sum of PFAS-20) – not detectable in the sample evaluated. The limit of 0.1 µg/L (100 ng/L) has applied since 12 January 2026.
- Lead – not detectable at the waterworks. Lead gets into the water almost only through old lead pipes in household plumbing, not via the supplier.
- Uranium 0.12 µg/L – unremarkable against a limit of 10 µg/L. In some regions uranium occurs naturally from the rock (geogenic).
- pH 7.51 – within the range of the Drinking Water Ordinance (6.5 to 9.5). The pH determines how corrosive the water is in household plumbing.
Water hardness in Wieck in everyday life
At 17.1 °dH, Wieck is in the hardness range “hard” (soft: below 8.4 °dH, medium: 8.4–14 °dH, hard: above 14 °dH).
- Dose detergent for the hardness range “hard” – a larger amount is needed; a water softener for the washing machine can save detergent.
- Limescale builds up quickly: descale the kettle about every two to three weeks, and taps and shower heads too.
- In your own house, limescale protection or a water softener can be worthwhile at this hardness; in a rented flat, the owner decides.
Baby food and low sodium: tap water in Wieck next to the bottled-water thresholds
Bottled water may only be labelled “suitable for preparing infant food” („geeignet für die Zubereitung von Säuglingsnahrung“) if it keeps to the maximum levels of the German Mineral and Table Water Ordinance (Mineral- und Tafelwasser-Verordnung, Annex 6). Here the published values for Wieck are shown next to them, each substance on its own. This is a comparison with labelling thresholds for bottled water, not a statement on whether your tap water is suitable for baby food. (Min/TafelWV, Anlage 6)
| Substance | Maximum level | Value in Wieck |
|---|---|---|
| Sodium | 20 mg/l | 24.9 mg/l – above |
| Nitrate | 10 mg/l | 2.06 mg/l – not above |
| Nitrite | 0.02 mg/l | below the detection limit (0.005 mg/l) – not above |
| Sulphate | 240 mg/l | 103 mg/l – not above |
| Fluoride | 0.7 mg/l | 0.3 mg/l – not above |
| Manganese | 0.05 mg/l | below the detection limit (0.002 mg/l) – not above |
| Arsenic | 0.005 mg/l | below the detection limit (0.001 mg/l) – not above |
| Uranium | 0.002 mg/l | 0.00012 mg/l – not above |
For context: the German Environment Agency (Umweltbundesamt) considers preparing baby food with bottled water carrying this label necessary only in rare cases, for example when tap water is temporarily allowed to contain more than 50 mg/l nitrate. (UBA 2016, p. 59) Water from lead pipes in the house is always unsuitable for infants. (UBA 2020, p. 16) The values apply at the waterworks. Questions about baby food are answered by your midwife, your paediatrician and the health office (Gesundheitsamt).
Frequently asked questions about tap water in Wieck
Can you drink the tap water in Wieck?
According to the verified values, yes: All tested parameters with a legal limit (20) meet the limits set by the German Drinking Water Ordinance (TrinkwV). WaterScore: 100 out of 100 (data coverage: 7 of 7 core parameters). This applies to the water from the waterworks – restrictions can only arise from old household plumbing.
How hard is the water in Wieck?
The total hardness is 17.1 °dH – hardness range “hard”. Dose detergent for the hardness range “hard” – a larger amount is needed; a water softener for the washing machine can save detergent.
Is there PFAS in the tap water in Wieck?
Not in measurable amounts: according to the published analysis by Wasser und Abwasser GmbH -Boddenland- (as of 29 July 2026), PFAS were below the laboratory’s limit of quantification. Since 12 January 2026, a limit of 0.1 µg/l has applied to the sum of PFAS-20. This means the sum of the four substances PFOA, PFOS, PFNA and PFHxS (PFAS-4) is also below the limit of 0.02 µg/l, which applies from 12 January 2028.
Do I need to filter my tap water in Wieck?
Based on the verified supplier values, a filter is not necessary. It can make sense if you do not like the taste. If you suspect lead pipes in an old building, a filter does not help; a laboratory analysis at the tap does – that is a question of the household plumbing, not of the water leaving the works.
