Department Water Resources and Drinking Water

Water Resources & Drinking Water

Our research concentrates on physical and chemical processes in groundwater, surface water and drinking water. We conduct basic and applied research on water resources, water contaminants, and water treatment to contribute to sustainable water management from local to nationwide scales.

By the end of the century, water temperatures in Swiss rivers will rise by up to 3.5 degrees if no action to protect the climate is taken. The rivers in the Alps are particularly affected. This is the conclusion reached by researchers from Eawag and the University of Basel in a research project funded by the FOEN.

Research Projects

The project investigates what measures are most effective in influencing a river corridor so that river restoration and groundwater flow systems can help to mitigate the effects of floods and droughts.
This project facilitates the exchange of data, maps and information on geogenic contaminants (focussing on arsenic and fluoride) via the web-based Groundwater Assessment Platform (GAP)
ReCLEAN examines the effects of energy decarbonization on the nitrogen balance within Swiss ecosystems. It will serve as a crucial foundation for developing sustainable policies in Switzerland.
By taking into account the interactions between surface waters and groundwater in real time, we improve operational groundwater modeling for drinking water, energy and agriculture.
The project investigates the impact of using the subsoil as a thermal battery on the underlying aquifer, with emphasis on the changes in groundwater chemistry, microbial activity, and groundwater fauna.
