AbstractSaturated hydraulic conductivity and intrinsic permeabilities were evaluated for eight soils and five solvent combinations. The solvents were kerosine, isopropyl alcohol, ethylene glycol, xylene, and water. Two hundred eleven column tests were run to determine saturated conductivity. An analysis of variance was performed to evaluate differences between intrinsic permeability for the different soils and solvents. A multiple regression analysis provided a predictive model for intrinsic permeability as a function of soil properties with an R²-value of 0.81. Moisture retention curves were determined using a pressure retention procedure for three soils and two solvent combinations--water and kerosine. Kerosine results do not follow a general pattern, demonstrating changes in procedure will sometimes become necessary when working with organic solvents in soils.
