Hydrogeochemical characteristics of groundwater impacted by acid mine drainage: Seasonal evolution of dissolved organic matter and heavy metals

Key Points

• Groundwater impacted by acid mine drainage shows significant changes in heavy metal concentrations during different seasons, indicating environmental stress.
• Seasonal shifts in dissolved organic matter were also observed, with peaks in specific months highlighting the complex nature of groundwater chemistry.
• The analysis employed a systematic approach to examine parameters affecting groundwater quality, drawing on data from various sites.
• Findings may inform management strategies for regions affected by acid mine drainage; further studies could validate these observations.
