Abstract: Groundwater quality models have been used lately in solving cases dealing with groundwater flow and pollutant transport problems. Finite element method is used in such problems and is considered a successful tool in this respect. However, the grid arrangements may take different shapes to discretize the domain of the problem. In case of the pollutant transport problems in groundwater reservoirs, the grid arrangements and its adjustment is of much importance in order to find a good solution otherwise serious drawback may result. In this paper, several shapes of grid arrangements were carried out for a case of pollutant transport in a groundwater aquifer. The case which compared well with the analytical exact solution  was adjusted and recommended for any groundwater quality model. This achievement will have an important potential in this respect.
