The research group Hydrogeology tackles the pressing regional and increasingly global challenges which affect groundwater and its protection as a natural resource. Scientific studies into the preliminary and follow-up protection of groundwater always take social and economic aspects into account. The group's regional activities include aspects of prealpine and alpine hydrogeology, global change, groundwater and surface water interactions, the passive and semi-passive remediation of large aquifers and the problems of groundwater in urban areas. Since the supply of drinking water will be one of the world's biggest challenges in the 21st century, the group also develops strategies for sustainable water supply in arid/semiarid areas and megacities. In this respect, an additional main focus of our work are investigations of groundwater quantity and quality changes due to revitalization of rivers.
