Noble gases used to sniff out the pathways of the Emmental’s groundwater
Research
Eawag
An Eawag researcher has helped to develop a new approach to tracking how river water enters the groundwater. In the test area within the Emmental, the flow time within the aquifer has been shown to be much shorter than previously assumed. This has potential consequences during dry spells.
Last ice age: colder than thought
Research
Eawag
The last ice age, about 20,000 years ago, was significantly colder than previously thought. This is shown for the first time by systematically analysed samples of groundwater collected around the globe and the inert gases dissolved in it. Swiss groundwater from Uster (ZH) also contributed to the results.
Biomass production in lakes becomes easier to de-termine
Research
Eawag
The condition of Swiss lakes has improved thanks to stricter protection measures, but less than expected. A new method developed by Eawag for calculating biomass production in lakes provides explanations and a basis for further water protection measures.
Autarky water module proves itself as a handwashing station
TechTransfer
Eawag
A mobile handwashing station that hygienically recycles its own water without water mains or sewage connection not only has great potential for deployment in countries lacking in infrastructure. The water wall also has great potential in public transport or at events.
Why study biodiversity? Because we depend on it!
Research
Eawag WSL
In the Blue-Green Biodiversity research initiative of WSL and Eawag scientists from around the world are working together to find solutions to the pressing challenges of biodiversity loss. The scientists explain in a video what they are working on – and why.
Precisely determining toxic concentrations
Research
Eawag
Ecotoxicological tests need to be extremely accurate – which often poses challenges in research and practice. Eawag has now developed a computer model that enables even more accurate testing at high throughput; the model is simple, widely applicable and saves resources.
