ABSTRACT
Liquid contaminants in the pore spaces between soil particles in the unsaturated zone. When a spill front from a large liquid release passes through the unsaturated zone, the liquid contaminants may form a continuous phase, filling a large fraction of the void volume. The mobilization/remobilization of a separate immiscible contaminant phase within the pore spaces of the unsaturated zone is controlled by physical properties and conditions of the porous medium, contaminant phase, and other immiscible phases present in locus no. 6. Soil type and moisture content also influence the response of a soil to temperature changes. Generally, sandy soils transmit heat more efficiently than loamy and clayey soils. The removal of fine-grained material from the porous medium by the newly-installed well usually is limited to the immediate volume of porous medium surrounding the well and usually ceases shortly after initiation of pumping, if the water well has been properly designed.
