In-situ remediation for arsenic-contaminated soils using iron and aluminum amendments under varying redox conditions.

Arsenic (As) contamination can threaten groundwater quality and human health, particularly where redox conditions fluctuate. Although iron (Fe) and aluminum (Al) (hydr)oxides strongly adsorb arsenate under oxic conditions, flooding can promote As(V) reduction to more toxic and mobile As(III) and destabilize the Fe(III)...
