Description	Solution of various problems related to soil contamination by non-aquacous phase liquids (NAPL) require a konwledge of capilalry pressure-saturation relationships. In soil-water-air systems,this relationship is frequently denoted as the soil water retention curve. Results of measurements of capillary pressure-saturation relatinships for tow two-phase systems (air-wter and air-oil) in two soils (loamy sand and silt loam) are presented. A prediction technique based on a modification of Leverettś concept was applied. The suitability of the method was tested for loamy sand and silt loam by comparison of the scaling factors based on theoretical interfacial tension values with the actual scaling factors between two capillary pressure functions. The data measured shows that the scaling factors for soil-air-water and soil-air-oil consist of the rations of the interfacial tensions and the wetting angles of both liquids. Both parameters cannot easily be predicted and should be studied in detail.
