Groundwater is an essential component of the Earth's freshwater resources and is also a major water source for agricultural and domestic uses where surface water is not enough for human living [1]. The availability of groundwater is particularly crucial in mining area [2]. In recent years, with the acceleration of industrialization and urbanization in China, excessive groundwater exploitation and groundwater pollution have been common in the whole
Surface water is an indispensable water resource of drinking and irrigation, which plays important role on human health and quantity of grain production. Hydrogeochemical process as well as quality assessment of 31 representative surface water samples from 3 typical lakes around Fuli abandoned quarries area were carried out. The cation is dominated by Ca 2+ and Mg 2+ , while the anion is dominated by HCO 3 and SO 4 2-. The two leading hydrochemical type are SO 4. HCO 3 -Ca.Mg (100%) in No. 1 lake, wheres HCO 3. SO 4-Ca.Mg (88.24%) and SO 4. HCO 3 -Ca.Mg (11.76%) of No.2 and No.3 lake. The chemical composition of No.1 lake are mainly controlled by carbonate dissolution and ion-exchange, the chemical composition of No.2 and No.3 lake is mainly influenced by both ion-exchange and dissolution of carbonate and silicate minerals, among which rock weathering is the most important factor. The recharging of the lakes is mainly derived from atmospheric precipitation with the existence of evaporation. The surface water in the study area, in general, is suitable for drinking and irrigation. The outcomes of this research provide a better understanding of hydrochemical mechanism of surface water around quarries, and it will help to improve management and sustainable utilization of water resources for local government.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
