Invertebrates on the beds of water bodies are observed closely, for they serve as indicators for the ecological status of running waters. A new Swiss-wide study by the aquatic research institute Eawag shows which species are especially good indicators, and how the monitoring and management of surface waters can be further improved.

It's World Toilet Day today. What may sound curious is intended to draw attention to a serious problem. Because worldwide, one in three people lack access to appropriate sanitation. In the Blue Diversion Autarky project, researchers are developing an off-grid toilet, with on-site treatment allowing valuable resources to be recovered.

ETH Zurich has awarded Stefan Achermann the Otto Jaag Water Protection Prize for his dissertation entitled "Exploring linkages between micropollutant biotransformation reactions and microbial community characteristics in activated sludge". This prize is awarded to outstanding dissertations and master theses at ETH Zurich in the field of water protection and hydrology. In his work, Stefan Achermann combined chemical-analytical and molecular-biological methods to investigate the degradation pathways of micropollutants in wastewater treatment plants.
