Abstract
Dense Non-Aqueous Phase Liquids (DNAPLs) induce variation in electric permittivity and resistivity. To better understand the effect of DNAPL on electrical permittivity and resistivity in a water saturated medium, we collected electrical resistivity, induced polarization and georadar data on a cell filled with glass saturated beads contaminated by HFE-7100 (hydrofluoroether). Time-lapses show GPR, ERT and IP data change in a different way due to their different sensitivity to the multi- phase of HFE, and to the chemical-physical process that occurs over time. The methods resulted to be complementary in the characterization of medium contaminated by DNAPL. Read More: http://library.seg.org/doi/10.1190/segam2015-5844594.1| File | Dimensione | Formato | |
