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.

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 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.

August 8, 2022Eight apprentices have successfully completed their training at Eawag as EFZ Laboratory Technicians and EFZ Business Administrators. Congratulations!

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 28, 2022Over the last six years, more than 160,000 people around the world have participated in online courses offered by Eawag, thus acquiring valuable knowledge about, for example, sanitation systems or municipal solid waste management.
