80% of Switzerland's drinking water comes from groundwater. Its protection is becoming increasingly difficult, especially in the densely utilised Central Plateau. New or newly focussed pollutants, such as PFAS or nanoplastics, are raising new questions. Higher water temperatures and longer periods of drought as a result of climate change are exacerbating the situation. Can suppliers continue to supply consumers with virtually untreated groundwater under these circumstances? Why have problems that have long been recognised, such as nitrate pollution, still not really been solved? Eawag researchers will address such questions at the Info Day. They will present results and tools that support practitioners and administrators in safeguarding the quality and quantity of drinking water resources.
