The purpose of this project is to determine the effectiveness and sustainability od naturally occurring alumina, iron, and manganese oxides in the unsaturated zone to treat high-arsenic water. Results of the study will be used to develop a methodology to transfer the technique to areas having high-arsenic water. Water containing arsenic concentrationof about 30 ug/L will be pumped from deeper aquifers and infiltrated into a one acre pond. Arsenic in the infiltrated water is expected to be sorbed on naturally occurring alumina and iron oxides in soil and water will recharge the shallow aquifer having arsenic concentrations of about 1 ug/L.
