Water Quality in Baden
The drinking water for the municipalities of Baden and Ennetbaden is sourced approximately 40 % from spring water and 60 % from groundwater. The well-known mineral-rich thermal water is drawn from separate springs.
Water Hardness: In the supply area, hardness is about 30 °fH (16.9 °dH), which corresponds to roughly 300 mg of calcium carbonate per liter.The hardness degrees (°fH = French hardness, °dH = German hardness) indicate the concentration of dissolved minerals such as magnesium and calcium. The higher the concentration, the “harder” the water.
✔ Conversion: °fH × 0.56 = °dH
Baden’s tap water is comparatively hard, which can lead to more limescale deposits in household appliances. Many people perceive the taste as particularly “mineral-rich.”
Drinking water is one of the most strictly controlled foodstuffs in Switzerland. Water quality is continuously monitored through laboratory tests.
Why Might a Drinking-Water Test Be Useful?
Although Swiss drinking water is rigorously monitored, contaminants can enter the supply beyond the house connection through pipes or fixtures. The owner is responsible for in-building quality. Pollutants such as heavy metals or microbes cannot be detected by sight.
A laboratory analysis provides clarity on your home’s water quality – especially important for households with sensitive individuals such as infants, pregnant women, or seniors.
Reasons for a Water Analysis:
- Regular consumption of tap water
- Noticeable changes in taste, odor, or clarity
- Infants or pregnant women in the household
- Use of water carbonators
- Uncertainty about the building’s pipe materials
