Benzinzusatz im Grundwasser: Wieso das Wasser im Aargauer Limmattal nach Benzin riecht
Ende Juni 2026 meldeten sich Bewohner aus dem Aargauer Limmattal, insbesondere aus Würenlos und Baden, wegen Benzingeruchs und -geschmacks im Trinkwasser. Ursache war der Benzinzusatz ETBE, der nach einem Benzinaustritt am 3. September 2025 auf der Autobahnraststätte Würenlos ins Grundwasser gelangte. Der Kanton Aargau informierte, dass das Trinkwasser trotz des Geruchs sicher und uneingeschränkt nutzbar sei.
