Note from the test report (in the German original): Wasserversorgung Rheinhessen-Pfalz GmbH · Prüfbericht Nr. 8114009 (freigegeben 21.07.2026), Versorgungsgebiet Hochbehälter Schwabenheim. Auf ihrer Karte der Wasseranalysen ordnet die WVR Schwabenheim an der Selz diesem Bericht zu. Die Probe stammt vom 12.05.2026 aus dem Ortsnetz in Schwabenheim (Kindergarten, Am Kindergarten, Hahn Wasserzähler), nicht aus Schwabenheim an der Selz selbst und nicht ab Wasserwerk; die Hausinstallation ist nicht erfasst. Es ist eine Einzelprobe. Trihalogenmethane bildet der Bericht nicht als Summe, deshalb fehlt dieser Wert hier.

Water at your own tap: The values describe the water the supplier delivers – not automatically the water at your tap. The water supplier is responsible up to the service connection (Hausanschluss); the building owner is responsible for the pipes beyond it. Lead can dissolve from lead pipes, leaded solder joints or old brass fittings, especially when water has stood in the pipes for a long time (stagnant water); this mainly affects buildings constructed before about 1973. If water has stood in the pipes for several hours, let it run until it comes out cool. If you suspect lead pipes, a lead analysis of the stagnant water by an accredited laboratory will help.

Background on household plumbing, not a measurement: in Schwabenheim an der Selz, 37 % of buildings with living space were built before 1970, and a further 11 % 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 Schwabenheim an der Selz

Water hardness in Schwabenheim an der Selz in everyday life

At 19.8 °dH, Schwabenheim an der Selz is in the hardness range “hard” (soft: below 8.4 °dH, medium: 8.4–14 °dH, hard: above 14 °dH).

Baby food and low sodium: tap water in Schwabenheim an der Selz 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 Schwabenheim an der Selz 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)

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.

Frequently asked questions about tap water in Schwabenheim an der Selz

Can you drink the tap water in Schwabenheim an der Selz?

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: 97.5 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 Schwabenheim an der Selz?

The total hardness is 19.8 °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 Schwabenheim an der Selz?

Yes, in measurable amounts: according to the published analysis by Wasserversorgung Rheinhessen-Pfalz (WVR) (as of 12 May 2026), the sum of PFAS-20 is 0.002 µg/l – that is 2 % 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 Schwabenheim an der Selz?

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.

Is the nitrate level in Schwabenheim an der Selz a concern?

The value of 37.9 mg/L is below the limit of 50 mg/L, but higher than in many other evaluated cities. The limit of the Drinking Water Ordinance also applies to preparing baby food; mineral water labelled “suitable for preparing infant food” („geeignet für die Zubereitung von Säuglingsnahrung“) may contain at most 10 mg/L nitrate. Boiling does not help against nitrate.
