AB: The objective of this study is to evaluate the effects of zero-valent iron (ZVI), granular activated carbon (GAC) and soil as materials to build permeable reactive barrier (PRB). Flow-through Column experiments were conducted to evaluate the reactivity and adsorptive capacity of various materials for Perchloroethylene(PCE) contaminated groundwater. Columns were packed with various materials such as ZVI, GAC, and Soil. A peristaltic pump was used to feed this medium at 2.5mL/h resulting in a hydraulic retention time of approximately 70h. The column which packed only the soil shows PCE contamination came out passing after 10 pore volumes. But the other columns are continued purification effect.
