Implication

Batch experiments show sediment characteristics influence arsenic mobility in groundwater, highlighting risks for water quality.

Key Points

  • Higher adsorption capacities in Mn- and Al-rich sediments correspond to lower dissolved arsenic in groundwater.
  • Desorption experiments reveal As(III) is more mobile under variable pH and redox conditions than As(V).
  • Statistical analyses identified sediment properties such as grain size and mineralogy as significant predictors of arsenic retention.
  • The study's findings support enhanced risk assessment and arsenic management in multilayer aquifer systems.
