The source of such contamination is varied, agricultural practices and industrial storage/spillage being identified as potentially hazardous threats. Current models of contaminant migration rely on the use of effective large scale parameters to describe typically Fickian processes and yet a number of recent studies have revealed distinct bypass mechanisms for transport processes in soils. We report here on the applicability of non-destructive, non-invasive El
