Science that matters

Green and blue food webs are wired differently

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. Read more

How rusting iron removes arsenic from water

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. Eawag researchers have for the first time made visible exactly what happens in this process in a new type of experimental set-up. Read more

Alpine fish biodiversity is amazingly young

A high fraction of the endemic biodiversity of the Alps is very old. The endemics – species found only in a confined area – have developed over the past millions of years during the cycles of glacial and interglacial periods. Fish, however, are an exception: most endemic fish species emerged only after the end of the last ice age about 15,000 years ago. Read more

With new ponds against amphibian extinction

Nature conservation pays off: amphibians benefit from new ponds - despite many causes of endangerment that still affect them. This is what researchers from WSL and Eawag found in a joint study using data from amphibian monitoring in the canton of Aargau. Read more

How nanoplastics enter the aquatic food web

The smallest of all plastic particles have remained largely unexplored until now, because they could not be detected in the environment. Now a study shows: 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.

Forum Chriesbach - A Sustainable Building for Aquatic Research
Eawag is focused on sustainable development in terms of its research activities. The Institute places a high value on the conservation of resources in operating its buildings and facilities. Built in 2006, Forum Chriesbach represents a highly energy-efficient building that is also exemplary in terms of its pioneering water management system. The administration and research building continues to set standards in terms of sustainability. Click here for the video.

Verhebts? A ressource-oriented Apéro
The connection obligation is a killer argument against the implementation of decentralised and resource-oriented sanitation systems. Besides, there is no implementation knowledge in Switzerland. The Wings program asked, "Is this really the case"? In the video, it dispels myths surrounding resource-based sanitation systems.

Professor Bernhard Wehrli: an active retirement
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. Though he has now retired, he remains committed to freshwater science and sustainability. Read more

Award for the Water Wall
The “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. Read more
