Note from the test report (in the German original): Gemünden a. Main · Trinkwasseranalyse für das Versorgungsgebiet Gemünden am Main, Stand 28.01.2026, veröffentlicht im GW-Manager-Öffentlichkeitsportal (verlinkt im BDEW-Wasserportal), untersucht von Institut Dr. Nuss. Die Werte sind unverändert aus der Datenschnittstelle des Portals übernommen. Laut Wasserportal liegen der Ortsmittelpunkt von Gemünden am Main 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.

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 Gemünden am Main

Nitrate 10.6 mg/L – about 21 % of the limit of 50 mg/L and in the medium range – such values occur in catchments shaped by agriculture. Boiling does not reduce nitrate.
pH 7.79 – 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 Gemünden am Main in everyday life

At 7.6 °dH, Gemünden am Main is in the hardness range “soft” (soft: below 8.4 °dH, medium: 8.4–14 °dH, hard: above 14 °dH).

Dose detergent for the hardness range “soft” – the lowest amount on the pack.
Limescale deposits are rare; kettles and coffee machines only need descaling every few months.
At this hardness you do not need limescale protection or a water softener.

Baby food and low sodium: tap water in Gemünden am Main 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 Gemünden am Main 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 Gemünden am Main
Sodium	20 mg/l	not in the report
Nitrate	10 mg/l	10.6 mg/l – above
Nitrite	0.02 mg/l	below the detection limit (0.01 mg/l) – not above
Sulphate	240 mg/l	not in the report
Fluoride	0.7 mg/l	not in the report
Manganese	0.05 mg/l	not in the report
Arsenic	0.005 mg/l	not in the report
Uranium	0.002 mg/l	not in the report

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 Gemünden am Main

Can you drink the tap water in Gemünden am Main?

According to the verified values, yes: All tested parameters with a legal limit (3) meet the limits set by the German Drinking Water Ordinance (TrinkwV). WaterScore (provisional): 100 out of 100 – the test report contains only 2 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 Gemünden am Main?

The total hardness is 7.6 °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 Gemünden am Main?

The published analysis by Gemünden a. Main 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 Gemünden am Main?

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.

Data coverage: 2 of 7 core parameters. Not in the test report: Lead, Copper, Arsenic, Uranium and PFAS (sum). Missing parameters are neither estimated nor counted as harmless: the score is based only on the values available and is therefore provisional. It is not a health assessment and says nothing about the water beyond the service connection. Methodology v3: how we calculate the WaterScore.
