February 19, 2026The Swiss Federal Institute of Aquatic Science and Technology (Eawag) has been newly commissioned by the Federal Office of Public Health as the National Reference Centre for Wastewater Monitoring. This work centres around the collection of health data from municipal wastewater, and particularly that of viruses that are known to be pathogenic. A new national mandate has also been introduced for the analysis of substances related to pharmaceutical and illicit drug use.

February 10, 2026An investigation in the canton of Zurich has shown that certain rare earth elements can enter bodies of water via wastewater treatment plants in concentrations that pose a risk to aquatic organisms. These elements are gadolinium, which comes from contrast agents used in healthcare facilities, as well as lanthanum and cerium, which are used in a number of wastewater treatment plants to remove phosphorus.

January 27, 2026WSL and Eawag join forces: the new WSL-Eawag Biodiversity Center links research on biodiversity on land and in water.

January 26, 2026Sociologist and political scientist Lisa Deutsch was awarded the ETH Medal for her doctoral thesis written at Eawag and ETH Zurich. Her research demonstrated how interdisciplinary and transdisciplinary research can be successful and how theory and practice can be effectively combined in research.

January 23, 2026To mark the 2026 World Economic Forum (WEF), the ETH Domain presented highlights from its research, demonstrating how artificial intelligence is paving the way for greater sustainability. Policymakers and business leaders learned about practical AI applications for the environment and society.

January 23, 2026Aquatic ecosystems are fragile. But just how fragile they are has been revealed in a new study by the Swiss Federal Institute of Aquatic Science and Technology (Eawag) and the University of Zurich. Researchers investigated how climate change is affecting amphipods by shifting the timing of leaf fall in autumn. These creatures feed on leaves and, as the base of the food chain, have an impact on the entire ecosystem.

January 16, 2026The Biodiversity Forum of the Swiss Academy of Sciences, together with over 50 experts, has compiled and recently published a report entitled ‘Understanding and shaping biodiversity in Switzerland’. Several Eawag researchers contributed to the report, sharing their expertise in the publication.

January 15, 2026The insecticide fipronil has been detected in Swiss waterways in concentrations that are critical for aquatic life. It has not been permitted for use as a plant protection product for many years. A study involving Eawag now shows that the most likely source of contamination is flea and tick repellents for pets.

January 12, 2026A new study provides precise data on the origin of plastic in the sea. It could be key to reducing this pollution in a targeted way.

January 6, 2026For years, Eawag has been committed to ensuring that its research findings are "open access" – in other words, accessible free of charge. Within the Swiss higher education landscape, its proportion of scientific publications that are open access is therefore among the highest.
