Note from the test report (in the German original): Laut OOWV wird Löningen aus den Wasserwerken Thülsfelde und Großenkneten versorgt. Hier die Werte des Wasserwerks Thülsfelde (Probenahme 26.01.2026); welches Werk Ihre Adresse beliefert, nennt der OOWV. Zum Vergleich Großenkneten: 7 °dH (weich), Nitrat 5,2 mg/l, Probenahme 26.01.2026. Gesamthärte 6,6 °dH – Härtebereich weich.

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 Löningen, 31 % of buildings with living space were built before 1970, and a further 13 % 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 Löningen

Water hardness in Löningen in everyday life

At 6.6 °dH, Löningen is in the hardness range “soft” (soft: below 8.4 °dH, medium: 8.4–14 °dH, hard: above 14 °dH).

Baby food and low sodium: tap water in Löningen 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 Löningen 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)

Values at the waterworks next to the maximum levels for bottled water “suitable for infant food”
SubstanceMaximum levelValue in Löningen
Sodium20 mg/l13 mg/l – not above
Nitrate10 mg/l4.3 mg/l – not above
Nitrite0.02 mg/lbelow the detection limit (0.003 mg/l) – not above
Sulphate240 mg/l42 mg/l – not above
Fluoride0.7 mg/lbelow the detection limit (0.1 mg/l) – not above
Manganese0.05 mg/lbelow the detection limit (0.005 mg/l) – not above
Arsenic0.005 mg/lbelow the detection limit (0.001 mg/l) – not above
Uranium0.002 mg/lbelow 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 13 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 Löningen

Can you drink the tap water in Löningen?

According to the verified values, yes: All tested parameters with a legal limit (16) meet the limits set by the German Drinking Water Ordinance (TrinkwV). WaterScore: 100 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 Löningen?

The total hardness is 6.6 °dH – hardness range “soft”. Dose detergent for the hardness range “soft” – the lowest amount on the pack.

Is there PFAS in the tap water in Löningen?

Not in measurable amounts: according to the published analysis by Wasserwerk Thülsfelde (OOWV) (as of 26 January 2026), 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 Löningen?

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.

WaterScore

Data coverage: 7 of 7 core parameters. 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.
