The underground water pollution of metropolitan areas is one of the major problems of the big cities such as Tehran at present. The main reasons of underground water pollution are excessive population growth, sanitary wastewater of buildings and industrial development. However, in this study the BOD5 of 9 wells in district 7 of Tehran municipality were sampled and analyzed. Due to the results and compare to the standards, the zoning maps of the BOD5 pollution are prepared. In ARCGIS, two interpolation methods of Spline and Kriging are used to produce the maps. Due to the results, it can be concluded that the Spline method is more suitable than the kriging for underground water pollution zoning.
