Note from the test report (in the German original): Gemeindewerke Schutterwald · Trinkwasseranalyse für das Versorgungsgebiet Schutterwald, Stand 29.07.2025, 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 Schutterwald 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.
Background on household plumbing, not a measurement: in Schutterwald, 40 % of buildings with living space were built before 1970, and a further 18 % between 1970 and 1979 (Zensus 2022, Statistisches Bundesamt, dl-de/by-2-0). (Zensus 2022) According to the German Environment Agency (Umweltbundesamt), lead pipes exist at most in houses built before 1973 – and by no means in all of them. Whether there are any in your house is known to the owner or a plumber. (UBA)
What the values mean for Schutterwald
- Nitrate 18.8 mg/L – about 38 % of the limit of 50 mg/L and in the medium range – such values occur in catchments shaped by agriculture. Boiling does not reduce nitrate.
- PFAS (sum of PFAS-20) 3 ng/L – about 3 % of the limit of 100 ng/L (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 0.3 µg/L – unremarkable against a limit of 10 µg/L. In some regions uranium occurs naturally from the rock (geogenic).
- pH 7.6 – 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 Schutterwald in everyday life
At 12.1 °dH, Schutterwald is in the hardness range “medium” (soft: below 8.4 °dH, medium: 8.4–14 °dH, hard: above 14 °dH).
- Dose detergent for the hardness range “medium”.
- As a rule of thumb, descale the kettle about every four to six weeks and the coffee machine as the manufacturer recommends.
- A limescale protection device is not a must at medium hardness; regular descaling is often enough.
Baby food and low sodium: tap water in Schutterwald 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 Schutterwald 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 Schutterwald |
|---|---|---|
| Sodium | 20 mg/l | 29 mg/l – above |
| Nitrate | 10 mg/l | 18.8 mg/l – above |
| Nitrite | 0.02 mg/l | below the detection limit (0.005 mg/l) – not above |
| Sulphate | 240 mg/l | 21 mg/l – not above |
| Fluoride | 0.7 mg/l | 0.1 mg/l – not above |
| Manganese | 0.05 mg/l | below the detection limit (0.003 mg/l) – not above |
| Arsenic | 0.005 mg/l | below the detection limit (0.001 mg/l) – not above |
| Uranium | 0.002 mg/l | 0.0003 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 Schutterwald
Can you drink the tap water in Schutterwald?
According to the verified values, yes: All tested parameters with a legal limit (19) meet the limits set by the German Drinking Water Ordinance (TrinkwV). WaterScore: 99.3 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 Schutterwald?
The total hardness is 12.1 °dH – hardness range “medium”. Dose detergent for the hardness range “medium”.
Is there PFAS in the tap water in Schutterwald?
Yes, in measurable amounts: according to the published analysis by Gemeindewerke Schutterwald (as of 29 July 2025), the sum of PFAS-20 is 0.003 µg/l – that is 3 % of the limit of 0.1 µg/l, which has applied since 12 January 2026. Even this sum of all 20 substances is below the limit of 0.02 µg/l that applies from 12 January 2028 to the sum of four of them (PFAS-4).
Do I need to filter my tap water in Schutterwald?
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.
