Science that matters


Exceptional diversity of whitefish

The diversity of whitefish species in Swiss lakes is unique and plays a central role in lake ecosystems. A comprehensive Eawag report now summarises the results of 150 years of research on these fish. Read more




Earthworms avoid tyre abrasion


A study by the Ecotox Centre, the Eawag and the EPFL shows that earthworms avoid soil that is heavily contaminated with tyre particles. However, the particles had no negative effects on the survival and reproduction of the animals. Read more

Green roofs and ponds as networks


To enhance biodiversity across aquatic and terrestrial systems, natural areas of high ecological value need to be interconnected. Collaboration between various stakeholders is essential to achieve this. Read more





Identifying cyanobacteria mats using the BlueROV
Our researchers used the BlueROV (Remotely Operated Vehicle) to track down cyanobacterial mats in order to observe their growth over the course of the year. They have successfully found the mats they were looking for and brought samples to the laboratory to analyze their possible toxicity. Watch the Video.

Review of the 2024 water policy
2024 was very warm and, at times, very wet. Groundwater reservoirs were filled and records were broken in hydropower production. Other topics in Bern included the expansion of hydropower, pesticides and PFAS. Read more



New website for the ARTS research project
Eawag and Empa are working with the Swiss Federal Office of Energy and several cantons to investigate how underground heat storage affects groundwater chemistry and microbiology in the subsurface. Read more
 





Groundwater – utilising and protecting the resource drinking water
Thursday, 4 September 2025, AKADEMIE, Empa-Eawag Campus, Dübendorf

80 percent of Switzerland's drinking water comes from groundwater. Its protection is becoming increasingly difficult, especially in the densely utilised Central Plateau. Can suppliers continue to supply consumers with virtually untreated groundwater under these circumstances? Why have problems that have long been recognised, such as nitrate pollution, still not really been solved? Eawag researchers will address such questions at the Info Day. They will present results and tools that support practitioners and administrators in safeguarding the quality and quantity of drinking water resources.

Cover picture: Artificial intelligence, data science, modelling and digitalisation are now central elements of water research. Eawag researchers, in particular the Department Systems Analysis, Integrated Assessment and Modelling, use these technologies and develop innovative approaches and algorithms to identify plankton species, predict the toxicity of chemicals, simulate riverine biocoenoses, study insect biodiversity and the development of floods and droughts.
