The pollution of the soil and of groundwater represents an environmental issue which is as old as complex, with regard to the migration mechanisms of various pollutant substances in both the soil and the subterranean environment. Also, soil pollution, in terms of food safety and drinking water, is a problem of permanent actuality. The paper presents the results of the research carried out in Săcel oilfield (Romania) that is currently under preservation. The results of the sample collection show that, in terms of legislation, the quality of the soil here falls below the threshold of intervention for sensitive types of use; from all the samples collected, 26.31% fall under normal values, 23.68% are within the normal limit alert threshold for sensitive land use types, and 7.90%, situated at a depth of 30 cm, exceed these normal values for the content of oil pollutants in the soil. In terms of protection of the soil resources and environmental protection, detailed knowledge of the content of pollutants and processes of selfpurification occurring in these soils are key factors for establishing measures and ameliorative actions needed to recover the economic value of the affected land. By observing this process in all the perimeters from where soil samples were taken, one can conclude that the self-purification process is the result of the intimate and concrete interaction in time between pollutant-oil residue and the soil - a living body capable of self-regeneration.
