Environmental pollution is one of the greatest problems in the world. Despite the convenience offered by developing technology in daily life, the extent of pollution to the environment produced by this technology and the nature of this technology is rapidly increasing day by day. Today, in both urban and rural areas, water, air and soil pollution is increasing with industrialization and construction. Environmental pollution is causing massive damage and animal ecosystems due to the effects of pollution on water, air and soil. Industrial, agricultural and domestic based pollutants directly affect the air, soil and groundwater in areas of undeveloped infrastructure and protective services. A required precaution is to develop and protect the ecosystem against environmental pollutants. Geographic Information Systems (GIS) is an effective technological tool used for the collection, management, interrogation and analysis of data related to the natural environment. This study is focused on presenting how to use GIS in the field of environmental pollution by providing examples and analysis. The major causes of pollution in the valleys are to be determined with The Analytic Hierarchy Process (AHP). Spatial exposure areas of industrial plants, households and agricultural lands will be determined with spatial analysis, and the results will be displayed on the relevant maps. The guiding supports will be created for determination of important areas of spatial planning and the development of applications for protecting these areas from pollution. The resulting maps also represent significant contributions to the establishment of environmental information systems for the Watershed Protection Action Plan.
