November 8, 2016Hydropeaking operations at storage hydropower plants affect hydrological processes and have adverse impacts on river ecosystems. For example, rapid and intense fluctuations in discharge can cause fish and macroinvertebrates to be flushed downstream or stranded.

November 7, 2016Eawag colleague Bouziane Outiti has been nominated for the 2016 Energy Globe World Award for his wastewater treatment project in Morocco. The award, which will be presented on 10 November at the World Climate Conference in Marrakech, is designed to highlight the existence of sustainable and innovative projects that tackle many of our environmental problems while protecting our resources.

November 3, 2016Stream and river restoration measures may be showcase projects for conservationists, but – in the absence of systematic monitoring – it is often unclear what benefits they provide for ecosystems.

October 31, 2016On 1 November 1986, a chemical warehouse at Schweizerhalle near Basel was destroyed by a fire. Aquatic life in the Rhine suffered catastrophic damage as a result of inflows of toxic, red-coloured firefighting water.

October 25, 2016In the coming years, around a hundred wastewater treatment plants (WWTPs) across Switzerland are to be upgraded with an additional treatment step in order to eliminate micropollutants. The method of choice is often ozonation.

September 29, 2016A study by Eawag and Zurich University researchers using a new imaging method has revealed that, surprisingly, cocaine accumulates in the eyes of zebrafish. The findings indicate that chemicals – especially psychoactive drugs – need to be assessed quite differently with waterborne exposure than, for example, when pharmaceutical substances are tested in mice. In particular, the uptake mechanisms and effects of cocaine in fish cannot simply be transferred to mammals or humans.

September 27, 2016Together with Eawag, the ETH organized at the beginning of September 2016 the second ETH Week. More than 180 students from 20 countries and all 16 departments accepted the challenge of formulating problems on the theme “Challenging Water” and searching for sustainable solutions.

September 16, 2016Switzerland’s lakes are not only diverse ecosystems, but also recreation sites, fishing grounds and energy sources. At this year’s Info Day, the tensions between these competing interests were explored. It was concluded that sustainable management calls for an understanding of the complex interactions occurring in lakes – which in turn requires scientific data and appropriate methods of observation.

September 8, 2016Biologists at Eawag have described a new amphipod species which is endemic to the Alps. While alpine lakes provide relatively undisturbed habitats for Gammarus alpinus, this species is being displaced by an invasive amphipod in Lake Constance.

September 6, 2016Lakes are major ecosystems. Their secrets have been investigated in Switzerland for more than 100 years. Nonetheless, scientists and their partners at the federal and cantonal specialist departments can still be surprised. For example, a fish in Lake Constance that had been declared extinct, or the results of Roman forest clearing around Lake Murten or concentrated antibiotic-resistant genes in the vicinity of wastewater discharges in Lake Geneva.
