In 2017, 68 cities (mostly in Europe) again took part in a large-scale project measuring drug levels in wastewater. The results for 2017 were published today by the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA).  Read more

Heavy rainfall can cause flash floods in urban areas. While data from flood events is required to model such phenomena, water levels and discharges are not routinely measured above ground. Eawag now plans to make use of widely available images and videos to estimate these values. Read more

When a person wearing a bright-orange protective suit and carrying a laptop climbs out of a sewer shaft, it could well be an employee of the Swiss Federal Institute of Aquatic Science and Technology (Eawag). Especially if this happens in Fehraltorf. Since 2016, Eawag has been constructing an internationally unique net of sensors that document water circulation in residential areas. Read more

How much thermal energy from Swiss lakes can be exploited without having an impact on their ecosystems? Eawag was commissioned by the Swiss Federal Office for the Environment (FOEN) to estimate the potentials with the larger lakes and rivers. Read more

In collaboration with the Centre for Hydrogeology and Geothermal Energy at the University of Neuchâtel, Eawag recently organised a PEAK Course on the controversial topic of “Groundwater and Agriculture”. A major focal point of the information and discussions was the issue of nitrate pollution. Read more

Tomorrow, 21 November 2017, will be Switzerland’s first ever Digital Day, with around 40 prominent businesses and institutions holding more than 80 events around the country to show what the significance of digitalisation will be for them and for Switzerland’s future. The President of the Federal Council, Doris Leuthard, will open the Digital Day at an event in Zurich’s main railway station, which will also be attended by federal minister Johann Schneider and Eawag Director Janet Hering.

Humans have so profoundly altered the Earth that, some scientists argue, our current geologic epoch requires a new name: the Anthropocene. But defining the precise start of the era is tricky. Would it begin with the spread of domesticated farm animals or the appearance of radioactive elements from nuclear bomb tests?  Read more

Compared to other foodstuffs, Switzerland’s drinking water shows low levels of contamination with antibiotic-resistant bacteria or resistance genes. This was demonstrated in a study of eight drinking water systems carried out by Eawag researchers on behalf of the Swiss Gas and Water Industry Association (SVGW) and water suppliers. Read more

A study by Eawag environmental social scientists has identified a total of 23 forums in Switzerland concerned with water-related issues, such as the Swiss Water Management Association (SWV), Water Agenda 21, the Swiss Water Association (VSA) and the Swiss Gas and Water Industry Association (SVGW).  Read more

Dried-up ponds, culverted streams, contamination with fertilisers and pesticides – the list of adverse effects caused by agriculture to water and waterbodies is a long one. Shortening this list is a major challenge, not only for agriculture but also for society as a whole. Supplying humanity with food is, after all, equally important. At the Eawag Info Day, experts demonstrated that the conflicts between use and protection can be addressed through objective dialogue, transparently stated goals and a broad raft of measures.
