The spatial requirements for surface waters specified in the Waters Protection Act represent the absolute minimum required to safeguard their ecological functions. The space provided along small streams is of particular importance, as material flows between terrestrial and aquatic ecosystems are not dependent on the width of the watercourse. This is shown by Eawag’s own investigations – and by a review of available studies, which was cited by the Federal Supreme Court in a recent ruling.

Researchers want to make use of the fact that coronaviruses excreted by infected individuals can be found in wastewater. If the viruses can be detected successfully, this may provide a much faster way of spotting a wave of infections than via testing of symptomatic individuals. To find out more, we interviewed Eawag researcher Christoph Ort.

Using a simple but ingenious strategy, a research team has successfully demonstrated how water quality downstream of wastewater treatment plants is influenced by a single pharmaceutical manufacturing site: as variations in the concentrations of compounds over time are dependent on production cycles, it is possible to distinguish between industrial and household emissions – even a long way downstream.

Contaminated waste water often flows into rivers and streams after heavy rains. Antibiotic-resistant bacteria thus also enter the waters. Eawag is researching exactly which ones and in what amounts as part of a national research programme.

Precipitation varies substantially in terms of location and time. With climate change increasing this variability, urban stormwater systems are also affected – not least in Switzerland. How exactly their performance may change has been investigated by Eawag researcher Lauren Cook in the dissertation she has written at Carnegie Mellon University in Pittsburgh, Pennsylvania (USA).

Geochemist Denise Mitrano received this year’s SNSF Eccellenza Professorial Fellowship. This fellowship enables her to establish her own research group at the ETH Zurich as an assistant professor. She would like to use this opportunity to get one step closer to her career goal: to become a full professor.

Degradation products of the fungal agent chlorothalonil are found widely in groundwater on the Swiss Plateau, even in places where it is used as drinking water. Dealing with these substances is becoming a challenge for waterworks. There is a wide range between rash immediate measures and concealing the problem. An Eawag fact sheet serves to contribute to an objective discussion and longer-term strategies.

Microbial communities are known to be indispensable for our planet. But surprisingly little is known about how they function. Researchers at the aquatic research institute Eawag are now shedding a little light on this subject: A new method enables them to observe the interaction between microorganisms.

Although use of the fungicide hexachlorobenzene has been banned since 2004, this compound is chemically stable – and accumulates in the polar regions where humpback whales replenish their fat reserves each year. Cell line studies conducted at Eawag have now shown that, while hexachlorobenzene does not have acute toxic effects, it can cause damage to DNA in humpback whale cells.
