Information about the "Non-Potable Water" Notice
Due to legal regulations, our tap water is currently marked with the notice:
"Non-potable water – due to sulfate levels similar to those found in high-quality mineral waters."
What has been measured?
In the latest analysis, a sulfate level of 396 mg/l was found.
This exceeds the limit set by the German Drinking Water Ordinance (250 mg/l), but is below or within the range of many natural mineral waters.
Is this concerning?
No. The classification as "non-potable water" is solely due to legal requirements.
Sulfate naturally occur in water and are required by the body for functions such as keratin production and bile activities. Elevated levels can have a laxative effect at very high consumption, especially in sensitive individuals or young children.
Comparison with well-known mineral waters:
- Eptinger Mineral Water: approx. 1,352 mg/l
- Ensinger Schiller Quelle: approx. 1,463 mg/l
- Franken Brunnen: approx. 1,470 mg/l
- Nussanger Tap Water: 396 mg/l
What is sulfate?
Sulfate is a natural mineral that occurs in soils and rocks. It enters groundwater through geological processes.
Many mineral waters advertise their sulfate content because it can promote digestion.
