Together with the Canton of St. Gallen, Eawag has been investigating the impact of the expansion of the wastewater treatment plant at Flawil to include a stage for the removal of micropollutants on water quality in the River Glatt. Initial results now show a very positive picture.

New technologies in the water sector can contribute to the flexible and sustainable development of urban water management and the sustainable utilisation of water as a resource. In a recent article in the journal Aqua & Gas, a team of researchers from the aquatic research institute Eawag shows what opportunities and risks are associated with this.

No tiger duck and no football club - the formula "yellow-black-grey" refers to the separation of wastewater streams at their source, i.e. at the toilet, washbasin or shower. This opens up new possibilities and saves resources. On the occasion of World Toilet Day on 19 November, a series of Eawag fact sheets shows how this can be done.

Terrestrial and aquatic food webs respond differently to changes in the environment. Understanding these differences is fundamental to identifying the species most important to an ecosystem and to effectively protecting biodiversity. This is shown by a study led by the research institutes Eawag and WSL and published in the journal Nature Communications .

Researchers at ETH Zurich and Eawag have developed an approach to accurately record and fully track the biodegradation of plastics in soils.

Scientists from Eawag, along with researchers from the former Eawag spin-off aQuatox-Solutions and the National Institute of Biology in Slovenia, have won almost 800,000 Swiss francs in the second phase of a contest run by the British Centre for the Replacement of Animals in Research.

researchers Wenzel Gruber and Urs Schönenberger have won this year's Otto Jaag Water Protection Prize for their dissertations. Reducing emissions of the climate-damaging nitrous oxide from wastewater treatment plants and reducing the leaching of pesticides from drainage systems are the topics.

Researchers at Eawag recommend setting up a monitoring system for antibiotic resistance in the synthesis report of the National Research Programme NRP 72 Antimicrobial resistance, similar to the wastewater monitoring for Sars-CoV-2.

In the 45 years since he began studying Chemistry at ETH Zurich, Bernhard Wehrli has been a research scientist, Head of Department and member of the Directorate at Eawag and Professor at ETH Zurich, as well as holding various other positions.

In many regions of the world, groundwater is contaminated with arsenic of natural origin. The harmful substance can be filtered out of water with the help of iron. researchers have for the first time made visible exactly what happens in this process in a new type of experimental set-up.
