Geographic information system (GIS) is an appropriate tool to enhance the  sustainable development of groundwater resources. Belmonte et al. (1999) introduced applying some of the GIS tools for integrative management in cultivated regions. Dixon (2005) obtained quality vulnerability maps of groundwater using fuzzy logic and GIS in Kansas State, USA. Pathak and Hiratsuka (2011) also applied qualitative modeling to evaluate the groundwater extraction management using GIS approach in Kathmandu, Nepal . They suggested some solutions to managers to make decision. In this study, we evaluated the parameters of electrical conductivity, sodium concentration, and the ratio of sodium absorption in Lake Urmia using geo-statistical methods and quality standardized modeling of the Ministry of Energy for agricultural water and introducing the GIS as an applicable tool for managers in decision making.
