摘要
Summary name="EnDivSummary">Difference in SO42- contents exists in groundwater in two banks of the Wudongde Hydroelectric Station. In particular, the SO42- contents in left side is generally higher than those in the right side. Combined with the study of water-rock interaction, hydrochemical data, temperature and hydrodynamic data, the characteristics of rock and mineral and hydrochemistry were analyzed. The cluster analysis was used to search the relativity of SO42- and other ions. It is found ultimately that the source of SO42- is related to the pyrite occurring in the formations. The difference in SO42- contents in the two sides is mainly due to the different in groundwater circulation.
