The paper presents theoretical model of the pollutant density changes in water environment. Spreading of the pollutant is modeled by strong pointed force on the pollution system in the water. This force appears as a strong short term pressure in certain point of the system after which it starts to move in one direction. Results of applying of this model shows that density of the pollution depends on mass of the pollution and the speed of the spreading of the pollutant in the aquatic system. One dimensional result of the pollutant density that is received, i.e. pointed direction of the pollutant stands only in the cases of precisely fixed conditions defined by modeling. For any other values that exceed these values the pollutant density value is equivalent zero value.
