Summary: In this paper is presented a developed model for a pollutant diffusion in a soil-water system, for specific conditions in a real study area. A model that allows the observations of the pollutant flow in the soil-water system and its behavior and interaction with the different system elements, is searched with the purpose of orientate and support the processes and techniques application for the pollutant soil and water remediation. The basic model conditions are: 1) The pollutant is introduced to the soil. 2) The pollutant flows from the soil to the water. 3) The introduced pollutant concentration is variable during the process. 4) The pollutant may saturate the soil. 5)The pollutant is adsorbed by the soil. 6) The model is developed in 2D, with the possibility to be expanded to 3D. The model uses a cellular automata that contains different zones with their own function rules. There are four considerate zones: i) Introduction of the pollutant zone. ii) Soil zone (a porous media). iii) Soil-water interaction zone. iv) Water zone.
