Verified drinking-water values
Note from the test report (in the German original): Wasserverband Heidekreis · Trinkwasseranalyse für das Versorgungsgebiet WVG Bomlitz, Stand 17.06.2025, 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 Bomlitz 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 Bomlitz
- Nitrate 0.52 mg/L – about 1 % of the limit of 50 mg/L and in the unremarkable range. Boiling does not reduce nitrate.
- PFAS (sum of PFAS-20) – not detectable in the sample evaluated. The limit of 0.1 µg/L (100 ng/L) has applied 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 – not detectable at the waterworks (limit 10 µg/L).
Water hardness in Bomlitz in everyday life
At 8.9 °dH, Bomlitz 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 Bomlitz 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 Bomlitz 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 Bomlitz |
|---|---|---|
| Sodium | 20 mg/l | 17 mg/l – not above |
| Nitrate | 10 mg/l | 0.52 mg/l – not above |
| Nitrite | 0.02 mg/l | below the detection limit (0.01 mg/l) – not above |
| Sulphate | 240 mg/l | 7.8 mg/l – not above |
| Fluoride | 0.7 mg/l | 0.16 mg/l – not above |
| Manganese | 0.05 mg/l | below the detection limit (0.01 mg/l) – not above |
| Arsenic | 0.005 mg/l | below the detection limit (0.0005 mg/l) – not above |
| Uranium | 0.002 mg/l | below the detection limit (0.00005 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 17 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 Bomlitz
Can you drink the tap water in Bomlitz?
According to the verified values, yes: All tested parameters with a legal limit (18) meet the limits set by the German Drinking Water Ordinance (TrinkwV). WaterScore: 99 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 Bomlitz?
The total hardness is 8.9 °dH – hardness range “medium”. Dose detergent for the hardness range “medium”.
Is there PFAS in the tap water in Bomlitz?
Not in measurable amounts: according to the published analysis by Wasserverband Heidekreis (as of 17 June 2025), PFAS were below the laboratory’s limit of quantification. Since 12 January 2026, a limit of 0.1 µg/l has applied to the sum of PFAS-20.
Do I need to filter my tap water in Bomlitz?
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.
