Development of a Methodology for Evaluating Subsurface Concentrations of Pollutants Using Electrical Polarization Technique
The study involves the introduction of an electrical polarization technique to in situ analysis of subsurface pollutants by measuring and analyzing the variation of soil-pollutant dielectric properties as a function of concentration of the pollutant in the soil. The developed system was modeled using transmission line theory, and the electrical parameters were optimized using the electrical circuit simulation software (Circuit Maker™) and the experimental results. Also, a methodology was developed to evaluate soil pore fluid concentrations via the use of two important electrical properties for the medium, which are resistance and capacitance.
