This research was designed to evaluate the performance of Constructed Wetlands (CW) for groundwater quality improvement. In the first phase of this study, performance of CW planted with cattails for Manganese (Mn) and Iron (Fe) reduction was evaluated. Subsequently, the efficiency of CW operated at 12 hours of hydraulic retention time was investigated at different plant harvest intervals. In the second phase of study, Mn and Fe removal efficiencies were 75-100 and 48-99%, respectively. Both Mn and Fe removal efficiencies for the CW system were not different between 4, 6 and 8 weeks of harvest intervals. However, the efficiency obviously increased after the first plant harvest. The results show that CW can improve the quality of groundwater before agricultural irrigation.
