Freshwater systems including surface waters and groundwater are important to society, but the quality of these water resources can be jeopardized by inorganic or organic pollutants leaking into the aquifers from nearby contaminated sites, such as landfills. In order to assess the risk associated with these sites, there is requirement of developing reliable and cost-effective methods for detecting contamination and mapping the spreading of it. Traditionally it is done by drilling boreholes, which is an expensive and ineffective approach.  

In this PhD study Pradip Kumar has applied and developed a new approach using geophysical methods for mapping and tracking the pollutants in the subsurface. These methods can be used to scan the ground from the surface and produce a 3D image of the ground outlining possible pollution. The new approach was successfully used in Grindsted, where groundwater and surface waters are polluted due to a former landfill and a factory site.

The PhD degree was completed at the Department of Geoscience, Science and Technology, Aarhus University.
