The flow of hydrocarbon contamination in near‐surface geological structures is correlated with changes in the electrical properties of the rock, such as permittivity and resistivity. The flow of large amounts of contamination over long periods is unstable and it can be only described with stochastic models, in which hydrocarbon contamination takes the form of plumes of variable size. The Ground Penetrating Radar (GPR) wavefield in a stochastic medium also has a stochastic character, and the properties of the scattered waves from the plumes, when observed, can be used for locating the contaminated areas. Field measurements carried out in former Soviet bases in Poland support this opinion.
