Description: Das Projekt "Detecting and Locating Non-Aqueous Phase Contaminants in Soils by Combining Three Geophysical Methods" wird vom Umweltbundesamt gefördert und von Universität Köln, Institut für Geophysik und Meteorologie durchgeführt. The developed methodology aims at locating and possibly determining the volume of Non-Aqueous Phase Liquid pollutants in the non saturated zone of soils up to the water-table in the depth-range 0-20 m. The methodology will especially apply to liquid hydrocarbons such as gasoline, diesel fuel and heavy fuel, to HAP-containing tars and to chlorinated hydrocarbons such as solvents and PCB's, for the investigation of industrially and accidentally contaminated sites with the interest of avoiding many boreholes. It consists in combining three existing geophysical tools (Ground Penetrating Radar, Radiomagnetotellurics and Electrical Direct Current or Electromagnetic Tomography) to take advantage of their complementarity and in enhancing their respective resolution by using improved processing methods. The operational methodology will be completed by a dedicated graphic software for interactive 3D data visualisation.
