The infiltration of a light nonaqueous phase liquid (LNAPL) into an unsaturated porous medium will result in varying amounts of water, LNAPL, and air within the soil voids. A simple and reliable method of determining the percent saturation of each fluid is needed to analyze laboratory infiltration experiments. This note reviews the available methodologies for determining the oil content in porous media and presents an experimental study of a simple and reliable method for determining water and oil contents in an unsaturated fine to medium sand. Key words: fluid saturations, oil content, gravimetric, extraction, assay.
