The basis for electrical resistivity methods is that an electrical potential difference (i.e., voltage) forms around current-carrying electrodes that are implanted within a conductive medium. The ...

The distribution of electrical potential around a current-carrying electrode depends on the distribution of the electrical resistivities of the materials surrounding the electrode. This principle is ...

Electrical resistivity is a basic property that quantifies a material’s opposition to current flow—it’s the reciprocal of conductivity. The resistivity of a material depends upon several factors, ...

Can we remotely detect groundwater contamination? Is it possible to detect subsurface contamination from the surface without drilling boreholes or wells? Let's look at a heavily contaminated rural ...
