Note from the test report (in the German original): Zweckverband zur Wasserversorgung der Böhmfelder Gruppe · Prüfbericht des Analytik Instituts Rietzler zur Probenahme am 01.10.2025 im Ortsnetz (Feuerwehrhaus Böhmfeld). Hitzhofen, Hofstetten, Oberzell, Baumfeld und Mühlthal liegen laut Wasserportal im Verbandsgebiet; der Verband nennt Hitzhofen und Hofstetten als versorgte Orte.
Background on household plumbing, not a measurement: in Hitzhofen, 21 % of buildings with living space were built before 1970, and a further 12 % 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 Hitzhofen
- Nitrate 40 mg/L – about 80 % 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.
- Uranium – not detectable at the waterworks (limit 10 µg/L).
- pH 7.08 – 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 Hitzhofen in everyday life
At 20.2 °dH, Hitzhofen 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 Hitzhofen 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 Hitzhofen 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 Hitzhofen |
|---|---|---|
| Sodium | 20 mg/l | 3.6 mg/l – not above |
| Nitrate | 10 mg/l | 40 mg/l – above |
| Nitrite | 0.02 mg/l | below the detection limit (0.005 mg/l) – not above |
| Sulphate | 240 mg/l | 12 mg/l – not above |
| Fluoride | 0.7 mg/l | below the detection limit (0.1 mg/l) – not above |
| Manganese | 0.05 mg/l | below the detection limit (0.005 mg/l) – not above |
| Arsenic | 0.005 mg/l | below the detection limit (0.001 mg/l) – not above |
| Uranium | 0.002 mg/l | below the detection limit (0.001 mg/l) – not above |
Against the other thresholds of Annex 6, the water would qualify as: low in sodium (“suitable for a low-sodium diet”) (Sodium 3.6 mg/l, threshold below 20 mg/l).
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 Hitzhofen
Can you drink the tap water in Hitzhofen?
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: 96.2 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.
How hard is the water in Hitzhofen?
The total hardness is 20.2 °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 Hitzhofen?
The published analysis by Zweckverband zur Wasserversorgung der Böhmfelder Gruppe 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 Hitzhofen?
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 Hitzhofen a concern?
The value of 40 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.

Missing parameters are neither estimated nor counted as harmless: the score is based only on the values available.
