Climate change will also have an effect on the surface waters and aquatic ecosystems of Switzerland. The extent of this effect has now been examined by Eawag researchers in a synthesis report commissioned by FOEN. All in all, it will be possible to maintain the high quality of Swiss waters through management and adaptation, however, this will entail higher costs, say the authors of the report. Read more

Wastewater contains valuable resources. However, because existing wastewater management systems have been designed primarily for pollution control and hygiene, the recovery of resources from wastewater is cumbersome. Read more

Cyanobacteria were among the first organisms to produce oxygen, which meant they were a significant milestone in the evolution of plants and animals. Countless species of cyanobacteria inhabit almost all habitats around the world. For her doctorate at Eawag, Marie-Eve Monchamp analysed sediment cores from ten different lakes around the fringes of the Alps, thus gaining an insight into the communities of cyanobacteria living over the past 100 years.

By systematically collecting samples from Switzerland’s rivers, “Progetto Fiumi” has documented more than forty species of fish. In addition, within the various species, the Eawag research group has found a rich diversity that had not been fully assessed before. The project thus provides a basis for the protection of this genetic and ecological diversity. Read more

Two studies by Eawag and the Ecotox Centre have once again shown that surface waters in agricultural catchment areas are heavily contaminated with plant protection products. Concentrations of individual substances persisting for several months pose a risk of chronic toxicity and, for extended periods, exceed the levels at which a risk of acute toxicity exists for aquatic plants and organisms. In most of the samples, 30 or more different active ingredients were detected. Studies of stream biodiversity and bioassays confirmed the threat posed by these mixtures of substances. Read more

Freshwater lakes are teeming with blue-green algae that produce a heady cocktail of substances. Little is known as yet about the health risks associated with these substances, although a review of the literature by Eawag scientist Elisabeth Janssen has now revealed some potentially harmful effects.

Today's Unesco World Water Day has the theme "Leave no one behind". Many people still do not have access to safe water and sanitary facilities for various reasons. But access to clean water alone is not enough, knows behavioural psychologist Hans-Joachim Mosler of the Department of Environmental Social Sciences. Read more
