Drinking water in 99102
For this postcode the responsible water supplier publishes several supply zones. Which of them serves an individual address is not published — below are the values of the zone with the most documented parameters, the remaining 11 underneath. The water supplier publishes 7 further local networks that cannot be clearly assigned to this postcode — they are listed on the water supplier page.
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.

Frequent questions about postcode 99102
- How hard is the water in Postcode 99102?
- Wasser-/Abwasserzweckverband Arnstadt und Umgebung (WAZV) publishes a total hardness of 10.6 °dH for the supply zone arnstadt gesamt (hardness range medium). 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: Stand: Januar 2026, retrieved on 11/07/2026.
- How much nitrate is in the drinking water in Postcode 99102?
- Wasser-/Abwasserzweckverband Arnstadt und Umgebung (WAZV) publishes a nitrate value of 14,3 mg/l for the supply zone arnstadt gesamt. The statutory parametric value is 50 mg/l; the measured value represents 29 % of the parametric value. Basis: Stand: Januar 2026, retrieved on 11/07/2026.
- Who supplies the drinking water in Postcode 99102?
- Wasser-/Abwasserzweckverband Arnstadt und Umgebung (WAZV). The values shown here come from the supply zone arnstadt gesamt 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.
