May 3, 2023An Eawag study shows that a large variety of living organisms leave their DNA traces in groundwater – which also depends on the land use in the catchment area. In future, these biological parameters could be used to assess groundwater quality.

April 28, 2023The hot summer made water supply security a political issue in 2022. Added to this were deficits in groundwater protection and "eternal" chemicals.

April 20, 2023In urban India, rising water scarcity and increasing pressure on water supply utilities have prompted the use of treated wastewater as an alternative source. A study of Eawag together with Indian partners explains how the use of sensors and automated chlorination can improve microbial water quality in on-site water reuse systems for increased user safety.

April 13, 2023Mining repeatedly causes water pollution. In the Global South, polluters often get away with it because the waters are seldom monitored. Satellite data can provide evidence of the origin, spread and extent of environmental disasters.

March 17, 2023The UN Water Conference is an urgent appeal to the global community to act on Sustainable Development Goal 6 - Clean Water and Sanitation. Eawag is willing to make its contribution and presents new approaches such as the Urban Water Flow Diagram, which improves water management in cities.

March 8, 2023The hydrogeologist Mario Schirmer has been appointed as adjunct professor by Canada’s Laval University. He tells us why he is committed to teaching, research and society.

February 16, 2023A new “Theory of Change” shows which psychological factors influence the use of decentralised water treatment technologies and which measures can support their introduction.

January 27, 2023Switzerland's groundwater is home to a multitude of hitherto unknown organisms. An Eawag research project is shining a light into the darkness and revealing this habitat’s exceptional biodiversity.

January 20, 2023Environmental DNA analysis of microbial communities can help us understand how a particular region’s water cycle works. Oliver Schilling, Professor at Eawag and the University of Basel, recently used this method to examine the water cycle on Mount Fuji. His results have implications for Switzerland as well.

January 10, 2023Eawag researcher and EPFL professor, Urs von Gunten has been awarded a prize for outstanding services by the journal Environmental Science and Technology (ES&T).
