This paper is part of a comprehensive study on soil pollution with liquid petroleum products. An experimental modelto simulate the natural state of soil horizons was imitated in the laboratory. By cracking underground or abovegroundpipes, which carry liquid petroleum products, the ground - underground – groundwater system undergoes changes. Ifimmediate action is taken, the system is less affected and remediation does not require costly techniques. If the accidentis found after a long time, the oil stain can seriously affect the soil and remediation methods do not provide goodefficiency. Pollutant migration, in the proposed arrangement, has been studied for several soil types. For each soil typethere were determined: capillarity, permeability and retention capacity, size distribution and density. Pollutantmigration, a petroleum product, was studied both on horizontal and vertical direction. There were calculated the travelspeeds of pollutant in the two directions and it was measured the width of the oil spill. Future research aims theremediation of these soils through methods that can be applied in the laboratory.
