Abstract: In recent years, the soil and its surrounding environment have undergone and faced irrecoverable changes and contaminations due to human activities. From among contaminating sources, hydrocarbon compounds are very important because they easily permeate into soil and aquifers due to storage or leakage (when transferred). Investigating contamination transfer peculiarities is, in fact, a vital and basic issue in the environmental studies because of their high potential of permeation into soil and aquifers. In the present research, effort has been made to introduce the mechanism of contaminations' dispersion and the basic equation in the related theory while applying boundary conditions, and extending the equation to study one-dimensional dispersion. Next, the results of one-dimensional dispersion in Bentonite with and without surface absorption in time intervals of 15, 30, and 90 days from the beginning of dispersion have been compared using the C-Tran Software. The results of this research study have revealed that the oil contamination density (concentration) variations along the soil column experience a decreasing trend; under the conditions of one-dimensional dispersion, the reduction rate is nearly constant 90 days after the commencement of the dispersion process.
