Si County is situated in northeast of the Huaibei plain in Anhui. Water shortage has always hindered economic development in the county. Through analysis of hydrogeological conditions, this paper identified groundwater abundance of major aquifers and their features in the area, mastered groundwater distribution law,based on the constructed water supply wells and water quality results, recognized groundwater level dynamic and analyzed water chemistry types of groundwater, and then analyzed the causes of water shortage: clay-dominated stratum lithology-led water-source type water shortage; and excess primary elements-led water quality type water shortage, finally put forward countermeasures and suggestions for relieving water shortage issues.
