March 9, 2021Monitoring of wastewater samples has the potential to provide a further indicator – alongside the number of cases, hospitalisations and deaths – to track the course of the pandemic. With support from the Federal Office of Public Health (FOPH), an existing research project is now being expanded from two to six wastewater treatment plants.

March 3, 2021New pharmaceuticals are being launched on the market all the time. It is of course their effectiveness in people’s health that is of central importance here, but at some point, their active ingredients or traces of them wind up in the environment, where they can have negative consequences. A large-scale EU project in which Eawag is also participating is now trying to help ensure that possible environmental impacts of pharmaceuticals are recognised by the pharmaceutical industry and the relevant approval bodies in the early stages of a drug’s development.

February 23, 2021A new fact sheet highlights the opportunities and challenges associated with greywater.

January 19, 2021The Ecotox Centre presents a new strategy to assess the quality of sediments. Sediments are of great significance in water protection.

January 6, 2021Each year, around 130 kilograms of mercury flow into Swiss wastewater treatment plants, which filter out the lion’s share from the waste water. This is shown by a survey of almost thirty wastewater treatment plants conducted by the Swiss Federal Institute of Aquatic Science and Technology (Eawag) and the Federal Office for the Environment (FOEN).

December 4, 2020The mobile and automated MS2field mass spectrometer allows measurements to be taken of harmful substances in surface waters with high temporal resolution. The initial measurements using the device are revealing the extent to which peak concentrations of pesticides, for example, have been underestimated by traditional methods.

November 26, 2020Sprawling carpets of floating plants are the result of too many nutrients. However, they could become part of solution strategies, Eawag researchers show.

November 3, 2020In agricultural areas, large volumes of water from fields, roads and paths drain directly into streams via manholes and other forms of artificial drainage. These shortcuts also transport pesticides into surface waters – and, according to a new study, in significantly larger quantities than was previously assumed.

September 23, 2020Air quality in Switzerland has improved but is still not good enough. To continue the monitoring of air pollutants which has taken place for many years in Dübendorf (ZH), today  federal government has opened a new station as part of its National Air Pollution Monitoring Network (NABEL) on the Empa-Eawag-campus.

September 8, 2020Process Engineer Adriano Joss from Eawag water research institute has been working for many years on wastewater treatment plants and the removal of micropollutants from water. Together with Ralf Kägi, Head of the Eawag Particle Laboratory, he has compiled the current status of knowledge on microplastics. In an interview, he presents the most important findings. We have recently posted detailed information on the website “Microplastics in the environment”.
