As part of a continuing programme to evaluate the potentials of non-invasive methods for rapid site assessment,<br>measurements have been made at a disused fuel distribution depot using geophysics techniques with particular<br>emphasis on the detection of sub-surface contamination. These include GPR, EM conductivity and 2D resistivity<br>imaging. The data have been analysed by a number of approaches and the results are compared with traditionally<br>acquired and chemically analysed soil samples.<br>The analysis of the data highlights the need for more work to be directed to the understanding of the physical processes<br>that give rise to the observed features, but encouragingly the comparison between the interpreted geophysics results<br>and the soil analysis has indicated that the non-invasive methods have potential to be developed into useful cost<br>effective screening tools. The direction for future work is discussed.
