Major ion concentrations were analysed for 29 groundwater samples collected from diverse aquifersin Wolonghu mining, northern Anhui province, China. The evaluation of groundwater quality andcontrolling factors analysis were obtained by the methods such as multivariate statistical approachand conventional graphical and calculation of a series of index. The results showed that the groundwatersamples are alkaline in nature, with the high value of TDS ranging from 686 to 3927 mg/L, theconcentrations of Cl- are low for all groundwater samples, whereas the contents of SO42- and HCO3-are high. The groundwater samples of QA and CA could be used for drinking and irrigation, whereasthe groundwater of LA could not be used for irrigation for the high TDS concentration. The groundwaterin the area is mainly controlled by silicate weathering, the evaporative dissolution and carbonatedissolution. Sulphate dissolution also played an important role in the groundwater quality.
