Drinking water in 88521
For this postcode Wasserwerk Ertingen 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 4 underneath.
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 88521
- How hard is the water in Postcode 88521?
- Wasserwerk Ertingen publishes a total hardness of 3,83 mmol/l for the supply zone Wasserwerk Ertingen, Entnahmestelle Hausanschluss, Teis 426045-ON-0001, Probennummer 226015427 — that corresponds to 21.5 °dH. 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: Publication by the water supplier, retrieved on 08/08/2026.
- How much nitrate is in the drinking water in Postcode 88521?
- Wasserwerk Ertingen publishes a nitrate value of 33 mg/l for the supply zone Wasserwerk Ertingen, Entnahmestelle Hausanschluss, Teis 426045-ON-0001, Probennummer 226015427. The statutory parametric value is 50 mg/l; the measured value represents 66 % of the parametric value. Basis: Publication by the water supplier, retrieved on 08/08/2026.
- Are PFAS detectable in the drinking water in Postcode 88521?
- Wasserwerk Ertingen publishes for the supply zone Wasserwerk Ertingen, Entnahmestelle Hausanschluss, Teis 426045-ON-0001, Probennummer 226015427 a sum value PFAS-20 of 0,0000014 mg/l (0.001 µg/l). The statutory parametric value is 0.1 µg/l; the measured value represents 1 % of the parametric value. For the sum of the 20 individual substances, this parametric value has applied since 12/01/2026. Basis: Publication by the water supplier, retrieved on 08/08/2026.
- Who supplies the drinking water in Postcode 88521?
- Wasserwerk Ertingen. The values shown here come from the supply zone Wasserwerk Ertingen, Entnahmestelle Hausanschluss, Teis 426045-ON-0001, Probennummer 226015427 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.
