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.

Will global warming force a shift in Biel’s drinking water intake? What caused the sudden turbidity of the water supply in the winter of 2009? Eawag has come up with answers to these and other questions for Energy Service Biel, and in the process, new questions have also emerged. Read more

August 25, 2017

Eawag researchers working on the research project “VUNA” have developed a new recycling process with which nutrients in urine can be harvested and used as fertilizer. In order to further their ideology of sustainable handling of water and wastewater and to work out and implement innovative concepts of water and wastewater treatment, the researchers have founded the Spin-off Vuna GmbH.  Read more

Arsenic-contaminated groundwater used as drinking water or for irrigation may threaten the health of 50 to 60 million people in Pakistan. This is shown by an Eawag-led study – co-financed by SDC – in which data from 1200 groundwater samples was analysed and combined with geological and hydrological parameters to generate a hazard map.

The emergence of new technologies requires conditions tailored to specific industrial sectors. Social scientists at Eawag have developed a conceptual framework describing the relevant innovation drivers. This should make it possible to identify factors hindering innovation and to design industry‑specific support programmes.  Read more

Eawag scientists handle the wastewater disposal line mess at NEST: At the Water Hub, they develop technologies for the treatment of separated wastewater streams. (Foto: Roman Keller)
July 24, 2017

It has been a year since the research building NEST was inaugurated by Empa and Eawag. Since then, scientists working in the research platform Water Hub have investigated new models and methods to recycle waste water. Experiments for processing and reusing grey water started in June.  Read more

Central Switzerland is shaped by Lake Lucerne, which offers not only rich landscape diversity but also habitats for numerous animal species. As part of the Swiss-wide “Projet Lac” study, the lake’s fish fauna was surveyed for the first time using standardized quantitative methods – producing some surprising findings. Read more

Surface temperatures in Lake Geneva on 1.7.2017: while in Geneva and on the southwest shore near Nyon, temperatures below 10 degrees were recorded, in Évian swimmers were enjoying 22 to 23-degree waters. (Source: meteolakes.epfl.ch)
July 13, 2017

If the wind blows away the warm surface waters of a lake, cold water flows in from the depths. As a result of this effect the temperature in Lake Geneva recently sank to 8 degrees. A project led by Eawag and EPFL had predicted this cooling event. Read more

Fieldwork on Lake Victoria
May 2, 2017

A conflict is developing in Africa’s Lake Victoria between fish farming in cages and the “normal” fishing industry. Added to that are other factors such as invasive species, wastewater pollution, pesticides and dam construction are putting the unique ecosystem under increasing pressure.  Read more
