Analytical solution of the problem of migration of polluting substances in the limited soil layer should be interesting, particularly in the case when the moisture and mass transport occur at shallow level of subsoil or ground water. In this case the data, sufficient for application of the analytical solution of the problem of mass transport, can be received from measurement over concentration of polluting substances in ground water and irrigation water together with an estimation of soil water balance. The purpose of this study was a development of the analytical solution of the mass transport model in the soil, taking into account the simultaneous influence of the chemical substances of the ground and irrigation waters on soil pollution. As a result of the solution of the designed system the analytical solution was received to predict (i) the influence of surface and subsoil (ground) waters on the change of concentration of soil chemicals at a given soil depth; (ii) the pollutant concentration at the uniform and non-uniformly distribution of the chemical substances in the soil profile (with limited depth); and (iii) the pollutant concentration in the soil profile under different leaching conditions. Accuracy of the results will be limited by the preconditions used at the statement of the problem and assumption of the equations.
