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.

On Wednesday, 5 May, the expansion of the Empa and Eawag research campus in Dübendorf began with a ground-breaking ceremony for a new laboratory building. This was attended by representatives of the two research institutes, the general contractor, the architectural office and the city of Dübendorf.

Their 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.

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.

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.

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.

Online biomonitoring systems offer the possibility of real-time monitoring of wastewater with organisms and enable wastewater treatment plant operators to react immediately to acute pollution in wastewater. So far, however, very little information is available on the suitability of online biomonitoring systems for such monitoring. An applied project by Eawag, the University of Applied Sciences Northwestern Switzerland and the Oekotoxzentrum is now set to change this.

The motto of today’s World Water Day is “Valuing water – What means water to you?”. With this motto, the United Nations wants to raise awareness of the vital importance of water and call on people to think about the value of water. In an interview, Eawag Director Janet Hering explains the importance of water for the aquatic research institute Eawag and also her personally.

There will be no general shortage, but water may be scarce depending on the region and time of year – conversely, heavier rainfall will lead to more local flooding. These are the findings of the Hydro-CH2018 project published today, Hydrological Principles of Climate Change. The extensive study with collaboration of the Eawag Water Research Institute was carried out under the lead of the Federal Office for the Environment (FOEN) in conjunction with the National Centre for Climate Services (NCCS). Climate change means that our use of water will have to change in future.

Rare earth metals such as cerium and gadolinium are increasingly entering wastewater from industry, but also from hospitals. This is shown by Eawag’s investigations at 63 wastewater treatment plants in Switzerland.

Monitoring 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.

Researchers have discovered a unique bacterium that lives inside a unicellular eukaryote and provides it with energy. Unlike mitochondria, this so-called endosymbiont derives energy from the respiration of nitrate, not oxygen.

New 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.

In Lake Constance, sticklebacks are occupying increasingly varied habitat types – in recent years even including the open and deep waters of the lake. In an Eawag review undertaken as part of the “SeeWandel” project, these uniquely diverse ecological adaptations are explained in terms of renewed contact between three stickleback lineages – including one originating from the Baltic region, whose genetic material is as yet rarely observed in other Swiss lakes.

Copepods (minute crustaceans with paddle-like feet) can differentiate between disturbances in water generated by nearby organisms and turbulence caused by wind or waves – an ability which helps them to find mates. It had previously been assumed that turbulent conditions would impede the quest for mates.

A new simulation study shows that climate change risks significantly altering water temperature, ice cover and mixing of many Swiss lakes. Mid altitude lakes are especially under pressure, running the risk of completely losing ice cover and no longer fully mixing twice per year. Such a change would have fundamental consequences for the functioning of lake ecosystems.

A community of sulfur bacteria grows in the northern basin of Lake Tanganyika and plays a key role in the lake's nitrogen cycle. With climate change, the deep blooms could expand southward, a new study shows. This could have drastic consequences for regional fisheries.

Beavers are master builders that reshape aquatic landscapes with their dams and lodges. The environments they inhabit experience an increase in the biodiversity of aquatic organisms, for example. Now, for the first time, an Eawag study from the wine-growing region known as “Zürcher Weinland” has shown that this is also true for streams in areas given over largely to agriculture. The rodents could therefore be interesting partners when it comes to enhancing bodies of water.

Surfaces 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.
