Abstract : The objective of the research presented in this report was to analyze subsurface contaminant transport by water at different experimental scales to provide information for moving from the laboratory experiments to field applications. The scale-dependent behavior of subsurface hydrologic and transport processes has been recognized as one of the key issues in assessing contaminant behavior for either compliance or remedial actions. Scale-dependent behavior means that the magnitude of parameters implications of scale dependency are apparent when using parameter values from laboratory columns to describe transport in a field setting, contaminant arrival times in aquifers were underestimated. The obvious solution is to conduct field experiments to obtain critical transport parameters, but field experiments are expensive, time intensive and have possible environmental ramifications (permitting requirements) compared to laboratory efforts. p4
