APPLICATION OF ELECTRIC POLARIZATION TO CONTAMINANT DETECTION IN SOILS
Preliminary experiments indicate the feasibility of constructing for field use a contaminant-detection instrumentation based on dielectric measurements. This study applies the technique of time-domain reflectometry to assess characteristic "signatures" of some selected contaminants and soil-contaminant mixtures. The results imply that a proper differentation between various signatures can be attained, allowing an assessment in regard to soil-contaminant status. The proposed technique is similar in principle to the induced-polarization method applied in mineral exploration.
