Electrical measurements were made on the surface of the earth with low frequency commutated current using nineteen separate frequencies and six electrode separations. Analysis of the data indicates that there is an effect of appreciable magnitude attributable to an interface 6000 feet below the surface.

A method for detecting zones of soil contamination with contrast-in-resistivity ecotoxicants, as well as geophysical methods for monitoring soil decontamination processes, are discussed in the article. A zone of soil contamination was designed and simulated using electrical prospecting methods - sounding and profiling. The direct and inverse problem of electrical prospecting of a contaminated zone in the form of a sphere inside a homogeneous soil body was solved in this work, while the main design dependencies were determined, which most accurately describe the data obtained experimentally. The proposed algorithm, based on adaptive step size random search, allows to quickly determine the depth and the effective radius of a zone of contamination with contrast-in-resistivity ecotoxicants, based on the results of profiling, and to estimate the degree of pollution by the ratio of the resistivity of the anomalous zone to that of the host medium.
