非水相液体（NAPLs），如溶剂和燃料是土壤和地下水中常见的污染物。溢出、地下储存罐泄漏和处置不当都会导致非核液体通过土壤释放和移动。NAPLs通过土壤的运动被认为是由于重力和/或毛细管驱动的不混溶相流。溶解组分的扩散和对流迁移、挥发、吸附和降解也被认为是非水相液体污染的重要过程。一个额外的运输机制，NAPLs蔓延在水面上，由于差分粘合剂和凝聚力的吸引力证明在这项研究中。
Nonaqueous phase liquids (NAPLs) such as solvents and fuels are common contaminants in soils and groundwater. Spills, leaking underground storage tanks, and improper disposal practices all result in the release and movement of NAPLs through soils. Movement of NAPLs through soil is considered to result from gravity- and/or capillarity-driven immiscible phase flow. Dispersive and convective transport of dissolved components, volatilization, sorption, and degradation are also considered important processes in NAPL contamination. An additional transport mechanism in which NAPLs spread on water surfaces due to differential adhesive and cohesive attractive forces is demonstrated in this study.
