Arsenic can be removed from water through rhizofirtration using phytostabirizing plants. The performanc e ol Eteocharis macrostachya in artificial or constructed wetlands for arsenic removal was determined at the prototype level. The concentrations of arsenic in the inlet water were maintained constant at five levels (0.05, 0.1, 0.2, 0.3 and 0.4 mg/L), and a flow rate of 130 L/d). Water samples were taken at the inlet and outlet of the wetlands during the entire testing period. Plant growth was also monitored to determine tolerance at the tested arsenic concentrations. The prototypes with plants were able to retain an average of 85 to 90% of the arsenic present in feed water containing concentrations in the range of 0.01 to 0.4mg/L. Plant reproduction values were above 116%, and no difference in growth size with respect to the control was observed. Results show that Eteacharis macrostachya tolerates high arsenic concentrations in flooded environments and behaves as a rhizofilterer retaining arsenic from water in artificial wetlands.
