Major ion concentrations were analysed for twenty eight groundwater samples collected from coal bearing aquifer in Sunan coal-mining area, Anhui Province, China. The conventional graphical and multivariate statistical approaches were used to discuss the geochemical characteristics, ions source and hydrogeochemical process of groundwater. Moreover, the applicability of groundwater is also evaluated based on a series of indexes. The results showed that the groundwater samples are mainly featured alkaline in nature, with the high value of TDS ranging from 860 to 5431 mg/L. The concentration of Cl- is low comparing with the concentrations of SO42- and HCO3-, otherwise, the cations are mainly composed of Na++K+ and Ca2+. Therefore, the hydrochemical types of groundwater samples are mainly divided into Na-HCO3 and Na-SO4 types. The dissolution of dolomite, evaporation and weathering of feldspar are the main hydro-geochemical processes, which contribute most ions to groundwater. The groundwater samples could not meet the demand of drinking water, comparing with the standard of WHO. Especially, all the groundwater samples are sealed for irrigation, with the higher values of RSC and SAR.

Abstract


Major ion concentrations were analysed for twenty eight groundwater samples collected from coal bearing aquifer in Sunan coal-mining area, Anhui Province, China. The conventional graphical and multivariate statistical approaches were used to discuss the geochemical characteristics, ions source and hydrogeochemical process of groundwater. Moreover, the applicability of groundwater is also evaluated based on a series of indexes. The results showed that the groundwater samples are mainly featured alkaline in nature, with the high value of TDS ranging from 860 to 5431 mg/L. The concentration of Cl- is low comparing with the concentrations of SO42- and HCO3-, otherwise, the cations are mainly composed of Na++K+ and Ca2+. Therefore, the hydrochemical types of groundwater samples are mainly divided into Na-HCO3 and Na-SO4 types. The dissolution of dolomite, evaporation and weathering of feldspar are the main hydro-geochemical processes, which contribute most ions to groundwater. The groundwater samples could not meet the demand of drinking water, comparing with the standard of WHO. Especially, all the groundwater samples are sealed for irrigation, with the higher values of RSC and SAR.
