Research

• Environmental Isotopes Group
  The main activities of the Environmental Isotopes Group are high sensitive transient tracer analytics, the application of environmental tracer methods in groundwater and lakes and numerical methods of data analysis and modelling of aquatic systems.
  
  
• Drinking Water Chemistry Group
  The research focuses on oxidation and disinfection processes and photochemical transformations in drinking water, wastewater and natural aquatic systems.
  
  
• Hydrogeology Group
  We work on field and model based methods in hydrogeology with special emphasis on investigation, monitoring and numerical process modelling. Our research foci are interactions between ground- and surface water, alpine and urban hydrogeology.
  
  
• Contaminant  Hydrology Group
  Organic pollutants: Investigation of bio(chemical) transformation in contaminated aquifers with stable isotope fractionation, and hydrology.
  Heavy metals: Surveys of river floodplains in Southeast Asia, risk assessment, mitigation.
  
  
• Water Rock Interaction Group
  The aim of our research is the provision of a scientific basis for decision making in water and waste management with regard to the potential long-term risk to groundwater resources associated with geogenic contaminants and the landfilling or utilisation of wastes.
  
  
• Chemistry of Water Resources Group
  We study basic biogeochemical processes that influence the quality of water resources, with a focus on inorganic contaminants.
  
  
• Molecular Environmental Geochemistry Group
  We study the geochemistry of major and trace elements in natural and engineered systems from a molecular-level perspective, with the aim to relate processes at the macroscopic level to distinct chemical species and their biogeochemical reactivity.
  
  
• Environmental Inorganic Geochemistry Group
  We study biogeochemical cycles of health-impacting trace elements from microscopic to global scales. Our current focus lies on the environmental behavior of selenium in the frame of the SNFS funded project: "The global biogeochemical cycle of selenium: sources, fluxes and the influence of climate".
