November 21, 2022Eawag 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.

November 17, 2022No 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.

November 15, 2022Researchers 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.

October 24, 2022Researchers at ETH Zurich and Eawag have developed an approach to accurately record and fully track the biodegradation of plastics in soils.  

October 18, 2022In 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. Eawag researchers have for the first time made visible exactly what happens in this process in a new type of experimental set-up.

September 27, 2022Janet Hering, Director of the aquatic research institute Eawag, signed a cooperation agreement with the International Atomic Energy Agency (IAEA) on Monday 26 September 2022. The cooperation between Eawag and the IAEA should help to further advance groundwater research and support the sustainable utilisation of groundwater resources.

September 26, 2022Floating on Lake Geneva since 2019 is the globally unique research laboratory called LéXPLORE. Now anyone interested can visit the platform virtually, at any time and from anywhere, and learn more about the instruments, the data collected, the research projects and the goals of LéXPLORE.

September 22, 2022The smallest of all plastic particles have remained largely unexplored until now, because they could not be detected in the environment. Now researchers at Eawag show: Nanoplastics stick to slimy biofilms, which can for example be found on stones in streams or rivers. When freshwater snails feed on the slime, the nanoplastics are taken up.

September 20, 2022Around 140 participants from public administration, private engineering firms and research took advantage of the Eawag Info Day in Lausanne to learn about and exchange information on new possibilities for collecting and using water data.

August 11, 2022As an additive in toothpaste, it protects our teeth from decay. But when fluoride occurs in nature in larger quantities and accumulates in groundwater, it can become a hazard for our health. For the first time, Eawag scientists have produced a detailed map of global fluoride contamination in groundwater and shown which regions of the world are particularly affected.
