Undoubtedly, water has been the cornerstone of human civilization and is also one of the most vital needs for sustainable and satisfying life throughout human life . The largest source of fresh water available to humans is located in the basement and inside geological formations. For a long time, all human civilizations have been built along with reliable water resources and now it has an important role in the comprehensive development of urban and rural areas. Increasing the amounts of industrial, domestic and agricultural pollutions is one of the major causes of groundwater degradation. Study of the there resources from the quantitative/qualitative viewpoints is of the crucial importance, especially in arid semi-arid regions, where considerable amounts of them are withdrawn. So far, numerous studies have been carried out to analyze the groundwater recourses quality and quantity through using different methods When dealing with development plans of a region, groundwater quality is one of the major parameters that should be considered. Groundwater quality should be assessed from physical and chemical viewpoints and meanwhile, groundwater quality index (WQI) is one of the most important in this case. Using data from 86 wells inn Tabriz Plain, WQI was computed (with using So4, Cl, Hco3, Total Dissolved Solids, Total Hardness, Electric Conductivity, Na, Ca, Mg, PH and K) for both dry and wet seasons during a 15 years period. The zoning maps were prepared using Kriging and Co-kriging methods through analysis of the various models. Overall analysis showed that Exponential Model in Kriging and Co-Kriging methods had better results than other models and moreover, the obtained results revealed that the groundwater quality of the studied region was poor for drinking consumption at the same period time.
