Implication

Analysis reveals groundwater pollution from coal mining activities, indicating significant hydrochemical impacts.

Key Points

  • The study identifies groundwater pollution with elevated levels of TDS, SO42−, Fe, and Mn in closed coal mine areas.
  • Piper's trilinear diagram and PMF model identified SO42− as the dominant ion among chemical constituents in surface and groundwater.
  • The mineralization of surface and groundwater is influenced by the weathering of silicate and dissolution of carbonate minerals.
  • Findings suggest mining activities significantly impact water quality, while agricultural impacts are comparatively minor.
