Walter Giger was a pioneer in the life cycle analysis of environmental pollutants. He analysed, but also insisted that action be taken when the harmfulness of a substance was proven. His work on toxic nonylphenols attracted worldwide attention. Walter Giger passed away on 6 November 2025. With his passing, Eawag and environmental chemistry have lost an outstanding researcher, but for many he was also a good friend.
