July 19, 2018Thanks to Copernicus – the EU Earth Observation Programme initiated in 2014 – environmental researchers now have access to vast amounts of high-quality satellite data. As this is also invaluable for aquatic research, Eawag is currently expanding its capacity in the area of remote sensing.

July 17, 2018Black plastic balls, which aim to reduce evaporation losses from open-air reservoirs under drought conditions, are not quite as efficient as previously assumed. Considerable quantities of water are already used in their production. 

July 12, 2018Researchers from Agroscope and Eawag have discovered that, under certain conditions, the herbicide glyphosate is rapidly degraded in Lake Greifen (Greifensee). The evidence strongly suggests that this is due to cyanobacteria using the substance as an alternative source of phosphorus.

July 5, 2018Small hydropower plants are often constructed on alpine streams, where they may have adverse impacts on sensitive ecosystems. Little is known, however, about the particular effects of individual plants, or the cumulative effects of multiple plants within the same river system. The current state of knowledge has now been reviewed in a study by Eawag researchers. 

July 4, 2018Janet Hering will take up her fourth term as Director of Eawag in 2019. Today, the Federal Council re-elected her based on the recommendation of the ETH Board. One of Janet Hering's important goals is that Eawag can integrate and synthesize knowledge from a wide variety of areas and thus make it useful in practice. 

June 28, 2018Aurin is now authorized by the Federal Office for Agriculture to be used as a fertiliser for every type of plant. Valuable nutrients from human urine are processed into high-quality liquid fertiliser — the upshot of Eawag’s “VUNA” research project. The Eawag spinoff of the same name as the project is now forging ahead with its urine recycling model.

June 20, 2018Antibiotic resistance is widespread in bacteria spores and preserved for years, as shown by experiments at Eawag and the University of Neuchâtel.

June 19, 2018Nanomaterials consist of tiny particles of different composition. They are used, for example, in textiles and can enter aquatic systems directly from the factory, while being worn or disposed of. For years, research groups at Eawag have been investigating the effects of artificially manufactured nanoparticles on human beings and the environment. Their preliminary conclusion: nanoparticles have a reputation worse than they deserve.

June 15, 2018The CENTAUR sewer control system has been recognized as the ‘Most Innovative New Technology of the Year’ at the 2018 Water Industry Awards in England. CENTAUR stands for ‘Cost Effective Neural Technique for Alleviation of Urban Flood Risk’ and is funded by the European Union’s Horizon 2020 programme. Eawag researchers were part of this project.

June 5, 2018Biological processes in rivers and brooks emit CO2, partly as a result of decaying plant litter that is deposited in the watercourses from surrounding land. Flowing water thus contributes more to the natural carbon cycle than would a terrestrial ecosystem covering the same area. Up until now, global carbon measures have only taken account of rivers that flow continuously. But about half of the world’s river networks consist of streams that are only periodically flooded. Their CO2 turnover has now been examined for the first time by 94 research institutes from all over the world, among them Eawag and the University of Zurich.
