Science that matters

Eawag researchers are using machine learning to map nitrate pollution in Swiss groundwater. This allows gaps in the measurement network to be filled and the causes of excessive values to be identified. The study is part of a larger project analysing the nitrogen cycle in Switzerland.

James Runnalls, software engineer at the aquatic research institute Eawag, receives the National Prize for Open Research Data (ORD) for developing the interactive online platform alplakes for monitoring and forecasting alpine lakes.

A new combination of data and statistical algorithms makes it possible for the first time to precisely track the movements of animals deep underwater. An initial study of flapper skate on the seabed around Scotland will help to develop targeted measures to conserve these Critically Endangered animals and designate suitable protected areas. The results have now been published in Science Advances.

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.
