Note from the test report (in the German original): Die Werte stammen aus der Übersicht 'Trinkwasserqualität 2025' der Stadtwerke Lutherstadt Wittenberg GmbH (Stand 15.06.2026, Durchschnittswert 2025 mit Vergleichswerten aus 2024). Das Trinkwasser wird nicht selbst gewonnen, sondern als Fernwasser vom Wasserwerk Lindau der Trinkwasserversorgung Magdeburg GmbH bezogen und von den Stadtwerken Wittenberg verteilt – die Analyse deckt den Verteilbereich der Kernstadt ab, nicht separat ausgewiesene Ortsteile. Direkt aus dem PDF gelesen und Wert für Wert verifiziert. Calcium, Magnesium, Ammonium, coliforme Keime, Trihalomethane und PFAS sind in diesem Dokument nicht ausgewiesen und daher nicht enthalten.

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.

What the values mean for Lutherstadt Wittenberg

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).
pH 7.63 – 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 Lutherstadt Wittenberg in everyday life

At 8.4 °dH, Lutherstadt Wittenberg 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 Lutherstadt Wittenberg 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 Lutherstadt Wittenberg 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”
Substance	Maximum level	Value in Lutherstadt Wittenberg
Sodium	20 mg/l	8.7 mg/l – not above
Nitrate	10 mg/l	below the detection limit (1 mg/l) – not above
Nitrite	0.02 mg/l	below the detection limit (0.01 mg/l) – not above
Sulphate	240 mg/l	68 mg/l – not above
Fluoride	0.7 mg/l	below the detection limit (0.2 mg/l) – not above
Manganese	0.05 mg/l	below the detection limit (0.003 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 8.7 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 Lutherstadt Wittenberg

Can you drink the tap water in Lutherstadt Wittenberg?

According to the verified values, yes: All tested parameters with a legal limit (14) meet the limits set by the German Drinking Water Ordinance (TrinkwV). WaterScore: 100 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.

How hard is the water in Lutherstadt Wittenberg?

The total hardness is 8.4 °dH – hardness range “medium”. Dose detergent for the hardness range “medium”.

Is there PFAS in the tap water in Lutherstadt Wittenberg?

The published analysis by Stadtwerke Wittenberg 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 Lutherstadt Wittenberg?

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.
