Note from the test report (in the German original): ENTEGA AG · Trinkwasseranalyse für das Versorgungsgebiet Darmstadt, Riedstadt, Weiterstadt, Erzhausen, Stockstadt, Biebesheim, Stand 2023, 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 Weiterstadt 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 Weiterstadt, 33 % 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 Weiterstadt
- Lead – not detectable at the waterworks. Lead gets into the water almost only through old lead pipes in household plumbing, not via the supplier.
Baby food and low sodium: tap water in Weiterstadt 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 Weiterstadt 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 Weiterstadt |
|---|---|---|
| Sodium | 20 mg/l | not in the report |
| Nitrate | 10 mg/l | not in the report |
| Nitrite | 0.02 mg/l | below the detection limit (0.05 mg/l) – cannot be assessed |
| Sulphate | 240 mg/l | not in the report |
| Fluoride | 0.7 mg/l | below the detection limit (0.1 mg/l) – not above |
| Manganese | 0.05 mg/l | not in the report |
| Arsenic | 0.005 mg/l | below the detection limit (0.002 mg/l) – not above |
| Uranium | 0.002 mg/l | not in the report |
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 Weiterstadt
Can you drink the tap water in Weiterstadt?
According to the verified values, yes: All tested parameters with a legal limit (10) meet the limits set by the German Drinking Water Ordinance (TrinkwV). WaterScore: 93.2 out of 100 (data coverage: 4 of 7 core parameters). This applies to the water from the waterworks – restrictions can only arise from old household plumbing.
Is there PFAS in the tap water in Weiterstadt?
The published analysis by ENTEGA AG that we evaluated gives no PFAS value. This does not mean there is no PFAS in the water; there is simply no figure for it. Since 12 January 2026, a limit of 0.1 µg/l has applied to the sum of PFAS-20. The supplier can tell you whether PFAS was measured and with what result.
Do I need to filter my tap water in Weiterstadt?
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.

Data coverage: 4 of 7 core parameters. Not in the test report: Nitrate, Uranium and PFAS (sum). Missing parameters are neither estimated nor counted as harmless: the score is based only on the values available. It is not a health assessment and says nothing about the water beyond the service connection. Methodology v3: how we calculate the WaterScore.
