Influence of the river revitalisation on the behaviour of organic micropollutants in the Thur valley

In the project we investigate the behavior of organic micropollutants during river-groundwater interaction in the hyporheic zone and the influence of river restoration on the behavior. The project aims to clarify whether there is a conflict between river restoration and drinking water production by bank filtration with regard to contamination with micropollutants. Therefore a mechanistic understanding of the underlying elimination processes will be achieved by a combination of field work, lab experiments and modeling. The project belongs to the project “Assessment and modeling of the coupled ecological and hydrological dynamics in the restored corridor of a river” in the Competence Center Environment and Sustainability of the ETHZ.
