Assessment of Groundwater Quality and Hydrogeological Characteristics of Ajabshir Plain, North West of Iran

The geological diversity, and water resource make the hydrogeology of Sarab Plain a uncommon and important water resource. Water quality at many coastal aquifers undergo high discharge and quality variations. Therfore, investigation of variations requires rigorous monitoring strategies more than usual methods. Groundwater resources are one of the almost important of fresh water that public use for agricultural and drinking uses. The importance of groundwater rises especially in coastal aquifer. Ajabshir aquifer is a coastal aquifer in adjacent of Urmia Lake. The Ajabshir Plain located in East Azerbaijan province that main recharge of aquifer is rainfall and springs that come from Sahand mountin in east of study area. Ghalechai is an important river in a study ara. Results of this investigation provides an improved understanding of the interaction of the hydrogeological components in Ajabshir aquifer and Urmia aquifer. In this research, investigate the hydrogeological characteristis of Ajabshir plain and then monitor the water quality variaton. The results showed in South West of region the facies of groundwater quality is Sulphate. The anomalies of sulphate is based geological factors and high evaporation in study are.
