-------------------------------------------------------------------------------------------------------------------------------------------Abstract Oyster shell has tremendous potential as a remediation material for the removal of arsenic from groundwater. A single arsenic removal system was developed with oyster shell for tube well water containing arsenic. The system removes arsenic from water by adsorption through fine oyster shell. Various conditions that affect the adsorption/desorption of arsenic were investigated. Adsorption column methods showed the removal of As(III) under the following conditions: initial As concentration, 100 µg /L; oyster shell amount, 6 g; particle size,
