March 30, 2021Ecotoxicological tests need to be extremely accurate – which often poses challenges in research and practice. Eawag has now developed a computer model that enables even more accurate testing at high throughput; the model is simple, widely applicable and saves resources.

March 25, 2021In the latest NEST podcast with Peter Richner, Tove Larsen talks about what we flush down the toilet, why problems should be solved at the source and why wastewater doesn't lie.

March 23, 2021Online biomonitoring systems offer the possibility of real-time monitoring of wastewater with organisms and enable wastewater treatment plant operators to react immediately to acute pollution in wastewater. So far, however, very little information is available on the suitability of online biomonitoring systems for such monitoring. An applied project by Eawag, the University of Applied Sciences Northwestern Switzerland and the Oekotoxzentrum is now set to change this.

March 22, 2021The motto of today’s World Water Day is “Valuing water – What means water to you?”. With this motto, the United Nations wants to raise awareness of the vital importance of water and call on people to think about the value of water. In an interview, Eawag Director Janet Hering explains the importance of water for the aquatic research institute Eawag and also her personally.

March 16, 2021There will be no general shortage, but water may be scarce depending on the region and time of year – conversely, heavier rainfall will lead to more local flooding. These are the findings of the Hydro-CH2018 project published today, Hydrological Principles of Climate Change. The extensive study with collaboration of the Eawag Water Research Institute was carried out under the lead of the Federal Office for the Environment (FOEN) in conjunction with the National Centre for Climate Services (NCCS). Climate change means that our use of water will have to change in future.

March 11, 2021Rare earth metals such as cerium and gadolinium are increasingly entering wastewater from industry, but also from hospitals. This is shown by Eawag’s investigations at 63 wastewater treatment plants in Switzerland.

March 9, 2021Monitoring of wastewater samples has the potential to provide a further indicator – alongside the number of cases, hospitalisations and deaths – to track the course of the pandemic. With support from the Federal Office of Public Health (FOPH), an existing research project is now being expanded from two to six wastewater treatment plants.

March 3, 2021Researchers have discovered a unique bacterium that lives inside a unicellular eukaryote and provides it with energy. Unlike mitochondria, this so-called endosymbiont derives energy from the respiration of nitrate, not oxygen.

March 3, 2021New pharmaceuticals are being launched on the market all the time. It is of course their effectiveness in people’s health that is of central importance here, but at some point, their active ingredients or traces of them wind up in the environment, where they can have negative consequences. A large-scale EU project in which Eawag is also participating is now trying to help ensure that possible environmental impacts of pharmaceuticals are recognised by the pharmaceutical industry and the relevant approval bodies in the early stages of a drug’s development.

March 2, 2021In Lake Constance, sticklebacks are occupying increasingly varied habitat types – in recent years even including the open and deep waters of the lake. In an Eawag review undertaken as part of the “SeeWandel” project, these uniquely diverse ecological adaptations are explained in terms of renewed contact between three stickleback lineages – including one originating from the Baltic region, whose genetic material is as yet rarely observed in other Swiss lakes.
