Hydrochemistry and Contaminants
Questions related to the chemistry of groundwater are an important topic in groundwater research and when managing groundwater resources. On the one hand, hydrochemical and isotope methods can provide unique information about the functioning of groundwater flow systems. On the other hand, there is a growing concern about groundwater contamination and a need for an improved understanding of the fate of contaminants in aquifers and methods for groundwater remediation.
The hydrochemistry and contaminants group addressed both of these topics with a strong focus on experimental studies at laboratory and field scale benefitting from the extensive field and laboratory infrastructure of the institute.
Context and Research Orientation
One of the main research topics of the group is the behavior of organic contaminants in the subsurface. This research includes the development of new methods to detect contaminant transformation processes, especially methods based on stable isotope analysis, and studies that investigate the contaminant behavior in complex subsurface environments. These system-oriented studies focus on the contaminant behavior in alluvial aquifers, at the groundwater-surface water interface or in karst systems. Other key research topics are the effect of land-use changes on the long-term evolution of groundwater quality and the effect of climate change on groundwater quantity and quality.
