Abstract :

Background and Objective: Considering the water crisis, especially in the last decades, investigation of groundwater quality and identification of the factors contributing to the decline of water quality in this resources are important. The information on available sources of groundwater in Ardebil show that, in the absence of excess surface water, much of the water consumed in the study area comes from groundwater sources. The most significant processes of geomorphologic study of groundwater are alluvial fans and terraces waters. Therefore, in this study it has been attempted to establish a relationship between the shapes and surface morphology of Ardebil plain and its groundwater resources tin order to estimate the groundwater resources based on what has been observed in the nature. Methods: In this study, to assess the quality of the groundwater samples, the quality data from wells was received from the Regional Water Company of Ardebil. Also the Arc GIS software was used to draw the maps. Findings: EC of groundwater in the Ardebil plain has been changed from 267 to 6580 μs/cm (with an average of about 1284 μs/cm) during the years 1994, 1998 and 2013. Discussion and Conclusions: The results show that the chemical properties of geologic formations are the most influential factors in the quality of groundwater resources in the region.
