Abstract
In this discussion the sources of nonequilibrium during contaminant transport are reviewed and the effects of contaminant solubility and geologic material organic carbon content on sorption equilibrium are reported. For experimental work with three neutral organic compounds (NOC’s) and geologic material from the saturated zone (TOC = 0.33 g kg−1), unsaturated zone (TOC = 2.6 g kg−1), and surface soil (TOC = 6.9 g kg−1), sorption nonequilibrium during solute transport through columns was detectable for contaminant-geologic material combinations yielding retardation factors >2.
