September 11, 2018Wastewater smells foul and is full of pathogens. For these reasons it is usually removed and disposed of quickly. The out-of-sight-out-of-mind strategy is, however, costly and opportunities are lost. At Eawag’s Info Day, experts in practice come together with researchers who are seeking new answers – for example, on how nutrients or heat can be recovered from wastewater.

September 7, 2018Eawag has a long history of innovation in the field of source separation technology. To understand this history, its collaborations and contexts, the directorate engaged historian Luke Keogh. His work resulted in the recently published “Flows of Science”, an intimate story of scientists at work.

September 5, 2018Climate warming is not the only cause of temperature changes in lakes, rivers and other bodies of water. The use of waterbodies for heating and cooling also leads to increases or decreases in water temperature. There has been little research to date, however, on how this affects aquatic ecosystems. This lack of understanding has been highlighted by a recent literature review carried out at Eawag and the University of Bern.

September 3, 2018In 2017, two artists from Saudi Arabia spent some time at Eawag as part of the Artists in Labs (ail) project and were inspired by research into artistic interpretations, Zahrah Alghamdi and Muhannad Shono. Now ail has created a video for both projects. 

August 30, 2018A long-term study of Switzerland’s major watercourses has been continuing for almost 45 years. An evaluation of the time series shows that as the climate is changing, so are geochemical processes. Most of the measuring stations show an increase in the concentrations of bicarbonate. The changes are caused by increases in temperatures, the presence of nutrients in the lakes and the acidity of the soil. On the other hand, following a peak in the late 1980s, nitrogen concentrations have been decreasing. The reasons for this are a reduced input of nitrogen in agriculture and improved elimination in wastewater treatment.

August 28, 2018When water samples are analysed with a mass spectrometer, peaks of compounds appear that are completely unknown, or that weren’t being looked for. If these compounds prove subsequently to be of interest to environmental researchers, evidence of their presence can be retrieved from the archived measurements. 

August 28, 2018Ecologist Florian Altermatt was appointed Associate Professor for Aquatic Ecology by the University Board on 27 August. Florian has been working in Eawag’s Department of Aquatic Ecology for over seven years as Group Head, and was awarded an SNF Research Professorship at the University of Zurich in 2014. 

August 24, 2018Cichlids belong to one of the largest fish families, with new species emerging all the time. These colourful, shimmering fish evolve so fast that Eawag researchers have now been able to practically observe them in the process of their evolution.

August 23, 2018Jennifer Inauen, group head within Eawag’s Environmental Social Sciences Department received the “Early Career Award” at this year’s European Health Psychology Society Conference in Galway. Every year, the European Health Psychology Society (EHPS) presents this award in recognition of new talent in the field of health psychology.

August 22, 2018The constantly growing number of new substances, materials and technologies are opening up new possibilities. However, their impact on the environment is often an unknown quantity and has to be carefully investigated before they are placed on the market. In order to support this process, the School of Life Sciences FHNW and Eawag, the Swiss Federal Institute of Aquatic Science and Technology, have created a joint professorship. The incumbent professor, Miriam Langer, will take up her post on 1st September in the new FHNW campus in Muttenz.
