GPR Mapping of a Dissolved Metals Plume Inside an Old Dyeing Plant at Leuze – Belgium

B042 Abstract 1 A two antennas (250 and 500 MHz) constant offset GPR field experiment was conducted on an industrial waste land (an old dyeing plant) to evaluate the technique potential in locating underground storage tanks (expected to be sources of a soil and water contamination by dissolved metals). Data were acquired along 52 parallel profiles inside the main hangar. 2Dsections analyses show areas with many diffractions and gaps. They also pointed out a zone of higher attenuation of the signal linked with higher soil conductivities probably due to the presence of dissolved metals. Finally 3 rectangular structures were showed
