Drinking water in Rodgau
5 supply zones — values can differ depending on the district. Below is the zone with the most documented parameters, the others collapsed underneath. To determine the exact match, look up the postcode.
How to read the share of the parametric value
12 % Share of the parametric value. The proportion of the permitted maximum that the measured value uses — here 12 %, so just over an eighth.
< 10 % * Below the limit of quantification. The substance was not detectable. The mark shows where the detection limit lies relative to the parametric value — the actual share of the parametric value is below that.
Several samples per year: for chemical parameters the mean value is given, for microbiological ones the highest measured value. There the parametric value is zero — a single finding would disappear in the average, and it is precisely that finding which is the information. Which reference applies is stated in the last column of the table.

No date is given for these values. The water supplier publishes the analysis without a sampling date and without a report date. When the water was examined is not apparent from the source — we do not add a date and we do not estimate one. What is stated is therefore only when we retrieved the document.

Frequently asked questions about drinking water in Rodgau
- How hard is the water in Rodgau?
- Zweckverband Wasserversorgung Stadt und Kreis Offenbach publishes the hardness range mittel for the supply zone Rodgau (ohne Nieder-Roden), Mühlheim-Dietesheim (teilversorgt), Mühlheim-Lämmerspiel, Obertshausen, Hanau-Steinheim, Hanau-Klein Auheim, Heusenstamm-Rembrücken. The hardness range is a classification under the German Detergents and Cleaning Products Act (soft below 8,4 °dH, medium 8,4 to 14 °dH, hard above that) and not a quality verdict — it indicates how much calcium and magnesium is dissolved in the water. Basis: 16.10.2025, retrieved on 11/07/2026.
- Who supplies the drinking water in Rodgau?
- Zweckverband Wasserversorgung Stadt und Kreis Offenbach. The values shown here come from the supply zone Rodgau (ohne Nieder-Roden), Mühlheim-Dietesheim (teilversorgt), Mühlheim-Lämmerspiel, Obertshausen, Hanau-Steinheim, Hanau-Klein Auheim, Heusenstamm-Rembrücken and apply to the water the supplier delivers. What happens between the building connection and the tap — in old lead pipes, for example — is not covered by these analyses; information on that is provided by owners, the health authority or an examination by an accredited laboratory.
General questions — how current the data is, limit of quantification, parametric values, who is behind this site — are answered under Questions & answers.
