Note from the test report (in the German original): Spessartgruppe · Trinkwasseranalyse für das Versorgungsgebiet Versorgungsgebiet Spessartgruppe, Stand 14.01.2025, veröffentlicht im GW-Manager-Öffentlichkeitsportal (verlinkt im BDEW-Wasserportal), untersucht von _Institut Dr. Nuss GmbH & Co. KG. Die Werte sind unverändert aus der Datenschnittstelle des Portals übernommen. Laut Wasserportal liegen der Ortsmittelpunkt von Alzenau in Unterfranken 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 Alzenau in Unterfranken
- Nitrate 39.2 mg/L – about 78 % of the limit of 50 mg/L and comparatively high for a city waterworks; the cause is usually nitrate from agriculture entering the raw water. Boiling does not reduce nitrate.
- Lead 3 µg/L – about 30 % of the limit of 10 µg/L, measured at the waterworks. Today’s limit is met; it will drop to 5 µg/L on 12 January 2028. Lead from household plumbing (old lead pipes) comes on top of this and is not covered by this value.
- Uranium – not detectable at the waterworks (limit 10 µg/L).
Baby food and low sodium: tap water in Alzenau in Unterfranken 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 Alzenau in Unterfranken 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 Alzenau in Unterfranken |
|---|---|---|
| Sodium | 20 mg/l | 22.2 mg/l – above |
| Nitrate | 10 mg/l | 39.2 mg/l – above |
| Nitrite | 0.02 mg/l | below the detection limit (0.01 mg/l) – not above |
| Sulphate | 240 mg/l | 41.8 mg/l – not above |
| Fluoride | 0.7 mg/l | 0.08 mg/l – not above |
| Manganese | 0.05 mg/l | below the detection limit (0.001 mg/l) – not above |
| Arsenic | 0.005 mg/l | 0.0006 mg/l – not above |
| Uranium | 0.002 mg/l | below the detection limit (0.001 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 Alzenau in Unterfranken
Can you drink the tap water in Alzenau in Unterfranken?
According to the verified values, yes: All tested parameters with a legal limit (15) meet the limits set by the German Drinking Water Ordinance (TrinkwV). WaterScore: 93.7 out of 100 (data coverage: 6 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 Alzenau in Unterfranken?
The published analysis by Spessartgruppe 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 Alzenau in Unterfranken?
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 Alzenau in Unterfranken a concern?
The value of 39.2 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.
