Abstract
For evaluating subsurface contamination, s ampling method (boring) is commonly used, but this method can not monitor the change of in-situ contamination and concentration with respect to time. The purpose of this study is to apply a measuring system for subsurface contamination in which a so-called FDR (Frequency Domain Reflectometry) and FDR-V (with Vector network analyzer) system are employed to measure the salinity and oil contaminant. This FDR and FDR-V method is a coaxial probe method, which allows the measurement of the dielectric. The experimental study indicates the possibility in measuring both the contaminant concentration and volumetric moisture content. Besides, it was possible to measures the oil infiltration behavior at the good accuracy by using one dimension column.
