In order to understand the impact of the mine drainage in the abandoned mine of the Yudong River Basin on the water environment, the pH value, the concentrations of SO42- and heavy metals (Fe, Mn, Cu, Cd, Pb, Zn) of the river water and mine water, and the contents of heavy metals (Fe, Mn, Cu, Cd, Pb, Zn) in the sediment were determined. The results show that the mine water is acidic, the concentrations of Fe, Mn and Zn exceed the local mine water discharge standards; the pH value, concentrations of SO42-, Fe, Mn and Cd in river water in the Yudong River Basin exceed the relevant standard limits of surface water sources; the water quality of the upstream river of the Yudong River Basin and the Chongan River are good, the results from the comprehensive pollution index method indicate that the water is not polluted; due to the discharge of mine water, the pH value, concentrations of SO42-, Fe and Mn of the water of downstream river obviously exceed the standard limit of surface water sources, and the evaluation result indicates that water of downstream river is severely polluted. Correlation analysis and principal component analysis show that river water is mainly affected by mine water and natural factors. The contents of Cu and Mn in the sediments do not exceed the soil background values of Guizhou Province, while the contents of Fe, Cd, Pb and Zn exceed the standard. The evaluation results from the cumulative accumulation index method show that the river sediment in the Yudong River Basin is slightly polluted by Cd, Pb and Fe, the sediment of the mine drain is moderately or strongly polluted by Fe.
