Benzine additive makes tap water taste in Baden and Würenlos

Residents in Baden and Würenlos in Aargau may notice a petrol-like taste in their tap water due to traces of the fuel additive ETBE found in the groundwater flow. Although the levels are significantly below the legal limit and the water is safe to drink and can be used without restriction, authorities are investigating how the residues entered the groundwater.
