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)

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

Changing people’s behaviour is no easy matter. Having developed a method that has been shown to promote behaviour change, Hans-Joachim Mosler of Eawag’s Environmental Social Sciences department has now set up a consulting firm – attracting considerable interest among development cooperation professionals in particular.  Read more

Urban water management 4.0 on World Water Day
March 22, 2017

The future of urban water management is also our future – this was the opinion of seven PhD students from Eawag came to, who decided to write a paper on the subject.  Read more

The water footprint indicates how much water is used to produce consumer goods. A study by Eawag scientists shows that there is a need for standardization in assessments of the grey water component. Comparability is impaired, for example, by the use of different water quality standards.  Read more
