The location of hydrocarbon contamination in the ground using the GPR method is based mainly on information taken from reflected signals. In the cases investigated in Polish contaminated sites, such signals were very seldom recorded. A long time after spillage, contamination takes the form of plumes with different size and distribution, which depends on geological and hydraulic properties of the ground. In this paper, it is shown that the set of hydrocarbon plumes should be de-scribed with a stochastic model, and such plumes may generate the scattered waves which cause changes in the power spectra. It has been observed that the power spectra of GPR signals over contaminated areas are quite different from such spectra over clear ones. These differences were discussed in this paper on the basis of theoretical analysis, numerical modelling and the results of GPR terrain surveys.
