September 16, 2022The “Water Wall” developed by Eawag researchers recycles handwashing and toilet flushing water in a closed cycle and can therefore be used in regions with scarce water resources or those without water and wastewater networks. Now the project has been awarded the Mülheim Water Award.

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.

August 9, 2022Throughout Switzerland, infections with bacteria of the genus Legionella are increasing significantly. Researchers at Eawag have now outlined how the growth of these microbial inhabitants of drinking water systems could be curbed with the help of other organisms.

July 18, 2022A study published today in Nature Microbiology highlights the great advantage of wastewater monitoring as being rapid, unbiased and cost-effective: the detection of genomic variants of SARS-CoV-2 in wastewater offers an early alert and can be based on fewer samples as compared to clinical samples. The bioinformatics tool developed by the groups of Niko Beerenwinkel and Tanja Stadler (ETH, Department of Biosystems Science and Engineering) in collaboration with Eawag and EPFL identifies variants of concern even at low abundance.

July 18, 2022As part of a new national research programme that aims to replace animal experiments in research, the National Science Foundation is supporting a project at Eawag. This opens up new possibilities for determining the toxicity of chemical substances based solely on tests with cultured cells and computer models. Animal experiments could thus be replaced.

May 31, 2022The biologically active, slow-flow sand filters of lake water treatment would remove nanoplastics from the raw water very efficiently. This was shown both in the laboratory and in larger, realistic tests and modelling.

May 4, 2022What has been a purification process in wastewater treatment plants for decades can also be used decentrally or semi-centrally as a recycling process for nutrients. Early separation of "solid and liquid" plays a key role here. It allows for flexible solutions in terms of process technology, especially in the treatment of urine. New studies also show that the processes can be used not only for human urine, but also for that of cows or pigs.

April 14, 2022Chlorination of drinking water reduces infections – and it changes the composition of the intestinal flora of young children, as a study published today in “Nature Microbiology” shows. The results indicate that the diversity of the intestinal flora isn’t reduced and bacteria associated with gut health are increased.

March 22, 2022For World Water Day 2022, the United Nations is focusing on our groundwater – an invisible treasure that it wants to bring into the social and political spotlight. For Eawag, groundwater as a resource has long been one of its most important research priorities. An overview.

February 10, 2022Eawag researchers have won a competition organised by Britain’s National Centre for the Replacement, Refinement and Reduction of Animals in Research (NC3R). The prize money is awarded for use in research to develop technologies to replace animal testing.

February 9, 2022Wastewater treatment plants are ‘hotspots’ for antibiotic resistance genes and bacteria but sewer overflows exacerbate the problem by disseminating them into rivers. Researchers at Eawag suggest ways to minimise these effects.

February 8, 2022Mining can have serious consequences for nature and the health of the population in countries of the Global South, where environmental laws are often only inconsistently implemented. In Hwange, in western Zimbabwe, people have been fighting water pollution from coal mining for years. But they were powerless against the operators – until doctoral student Désirée Ruppen launched a citizen science project in 2018.

February 4, 2022Those who have just undergone surgery in the hospital, with their weakened immune systems, are easy prey for pathogens that lurk on a wide variety of surfaces. Even careful disinfection can only partially prevent these hospital-acquired infections. One hope in the fight against the pathogenic bacteria are bacteriophages. Eawag researchers were able to show that they improve the removal of pathogens from surfaces, especially in combination with chemical disinfection.

November 17, 2021The separation toilet save! has won the Design Award Switzerland 2021. This is also a milestone for Tove Larsen. She is a member of the Eawag Directorate and has been researching for almost 30 years how the nutrients in wastewater can be recovered in a useful way. In this interview on the occasion of World Toilet Day 2021, she explains how crucial our handling of wastewater is for climate change and for achieving the SDGs sustainability goals.

November 17, 2021Together with a team of researchers and designers, Kai Udert has designed a toilet system that makes it possible to recycle nutrients from wastewater on-site. As a result, valuable nutrients can be recovered and used as fertilisers so that they no longer end up in lakes and oceans where they do a lot of damage. Now he wants to make the system ready for market together with industry partners.

September 23, 2021The "gene scissors" CRISPR/Cas9 can be used to precisely modify genes in order to study their function in an organism. A researcher at Eawag has now succeeded for the first time in establishing the gene scissors for a fish cell line of rainbow trout. This means that, as of now, genetically modified cell lines can be produced. These allow alternatives to ecotoxicological tests on living animals.

June 18, 2021Bacteria from an Indian landfill could help eliminate contaminated chemicals. The focus is on pesticides such as lindane or brominated flame retardants, which accumulate in nature and in food chains. Researchers at Eawag and Empa used these bacteria to generate enzymes that can break down these dangerous chemicals.

June 1, 2021The Zambezi River Basin in southern Africa is a high-quality waterscape. But current rapid development threatens the waters of the Zambezi, particularly its tributaries. The challenge will be to ensure that mitigation measures keep up with population and economic growth to avoid degradation of water quality degradation.

April 29, 2021Their very small size means that rotaviruses are difficult to filter out of water. But these pathogens are among the leading causes of gastrointestinal infections, especially among children in developing countries. Now, a team of researchers from Empa and Eawag has demonstrated an approach that could make rotaviruses easier to remove in the future.

March 9, 2021Monitoring of wastewater samples has the potential to provide a further indicator – alongside the number of cases, hospitalisations and deaths – to track the course of the pandemic. With support from the Federal Office of Public Health (FOPH), an existing research project is now being expanded from two to six wastewater treatment plants.

March 3, 2021New pharmaceuticals are being launched on the market all the time. It is of course their effectiveness in people’s health that is of central importance here, but at some point, their active ingredients or traces of them wind up in the environment, where they can have negative consequences. A large-scale EU project in which Eawag is also participating is now trying to help ensure that possible environmental impacts of pharmaceuticals are recognised by the pharmaceutical industry and the relevant approval bodies in the early stages of a drug’s development.

February 4, 2021Surfaces which are frequently touched by many different people may be contaminated with the coronavirus, but the risk of infection via this route is low. However, regular collection of samples from door handles, buttons or keypads could be useful for monitoring the course of the pandemic.
