January 25, 2024At night or during cold winter days, lake water cools faster near the shore than in the middle of the lake. This creates a current that connects the shallow shore region with the deeper part of the lake. An international team led by Eawag researchers were able to show for the first time that this horizontal circulation transports gases such as oxygen and methane.

December 12, 2023Field studies by Eawag researcher David Janssen in southern Greenland show that the heavy metals in the rivers are largely of natural origin, and that the influence of mining and agriculture is negligible, at least during the period observed.

December 1, 2023A team of seven current and former Eawag researchers will receive the Swiss Chemical Society’s Sandmeyer Prize in 2024 for the development of advanced wastewater treatment for the degradation of micropollutants using ozone. And the most amazing thing is: Just about 15 years have passed between basic research and large-scale technical implementation. This incredible timetable was only possible thanks to the wealth of knowledge already available at Eawag and the fact that interdisciplinary collaboration is a matter of course at the Swiss aquatic research institute.

November 16, 2023A comparison of three Swiss lakes with the Great Lakes of North America show that the quagga mussel is spreading with a similar dynamic.

November 9, 2023Over the next 20 years, Austria and Switzerland will be investing more than CHF 1.4 billion in flood protection and ecological enhancement measures on the Alpine Rhine. As well as protecting the Rhine valley against flooding, the aim is to promote careful management of groundwater resources. With a new method, scientists from Eawag and the University of Neuchâtel are providing support for International Rhine Regulation planners.

October 17, 2023The guidelines of the WHO list only four substances produced by cyanobacteria. This is a small fraction of all the metabolites that can have ecotoxicological effects.

August 24, 2023This can indirectly affect the survival of fish populations and may be one of the reasons for the fish decline we are currently observing in Switzerland.

August 9, 2023In the scientific journal Nature, a team including a member of Eawag published a study on the development of biodiversity in European inland waters, based on invertebrates.

June 22, 2023CO2 emissions from heterotrophic respiration could increase by 40% by the end of the century.

June 7, 2023Nutrient changes, invasive species and climate change have a major impact on the ecosystem of Lake Constance. This is the conclusion of a large-scale project conducted by seven institutions in Switzerland, Germany and Austria. At the close of the project, the results will be presented at two events.
