In order to determine the pollution status of the southern part of Rafsanjan plain alluvial aquifer, about 90 samples from groundwater discharge points (mainly wells) were collected. The samples were analyzed using ICP – MS technique and the concentration of As, Hg, Pb, Cd, Al, Fe, Cr and Ni elements was determined. Afterwards, using Arc GIS, the isoconcentration maps of these elements was prepared. Based on these maps, among the elements analyzed, the concentration of As, Hg, Pb, Al, Fe, Cr, Ni ,Cd in some parts of the plain is above the permissible limit for drinking water. In this article the details of concentration variations, as well as the influencing factors are discussed.<\div>
