Seismic Characterization of a Contaminated Site Using a Multi-Approach Technique

B032 SEISMIC CHARACTERIZATION OF A CONTAMINATED SITE USING A MULTI-APPROACH TECHNIQUE Introduction G.GRANDJEAN and A.BITRI BRGM BP 6009 Orléans France Since several decades numerous studies on contaminated sites have demonstrated that the physical characterization of the soils remains an important process that conditions the efficiency of remediation techniques. Improvement in safety and substantial cost savings can be realized with the appropriate use of geophysical methods. Of course the understanding of the limitations and applications of each method is critical to its success. As examples ground-penetrating radar is a suitable tool for delimiting the contamination plumes geometry (Grumman and Daniels 1995)
