Optimising wastewater management and protecting water bodies

Natural waters are regularly polluted by the discharge of wastewater from combined sewage systems. With the help of a “digital twin”, the management of wastewater systems can be improved and water pollution decisively reduced.

September 23, 2022Insects that live entirely or partly in freshwater have a much lower proportion of invasive species than insects that live on land. This is shown in a study by the Swiss Federal Institute for Forest, Snow and Landscape Research WSL in collaboration with the Swiss Federal Institute of Aquatic Science and Technology Eawag and an international team of researchers.

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 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.

September 1, 2022For a long time professional fishermen have known that there is not just one whitefish species in Switzerland, but a whole range of species each with their own specialization and local name. Researchers have now analysed the entire genome of the various whitefish and shown how specialists have all developed independently of each other in each lake region.

August 24, 2022Of over a thousand lakes studied worldwide, about one in ten shows strange behaviour. In general, there is an increasing tendency for aquatic ecosystems to tip over. The ecological stability of lakes is decreasing, especially in regions with low GDP and large human populations.

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 4, 202225 years ago, urine-diverting toilets were no more than an idea, challenging the central paradigm of wastewater treatment plants. Since then, however, modular water technologies have become increasingly important. Using a new method, scientists at Eawag have mapped the dynamics of this transition.

July 19, 2022Even though industrial wastewater is treated at state-of-the art plants, the sheer variety of synthetic organic compounds from the chemical and pharmaceutical industry which end up in surface waters are seriously underestimated. This is shown by a new study carried out by Eawag and ETH Zurich.

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.

June 28, 2022Africa is home to a large part of the world's biodiversity. Many species are native only to this continent. So far, the genome of only a tiny proportion of them has been decoded, but this is an important prerequisite for their protection. The large-scale African BioGenome Project, in which Eawag researchers are also involved, now aims to change this.
