Typha

In the wetlands of Idaho, the formation of an Fe(III) precipitate (plaque) on the surface of aquatic plant roots (Typha latifolia, cat tail and Phalaris arundinacea, reed canary grass) may provide a means of attenuation and external exclusion of metals and trace elements (Hansel et al, 2002). Iron oxides were predominantly ferrihydrite with lesser amounts of goethite and minor levels of siderite and lepidocrocite. Both spatial and temporal correlations between As and Fe on the root surfaces were observed and arsenic existed as arsenate-iron hydroxide complexes (82%).

It is necessary to use statistical procedures to assess chemical dynamics. The amount of Zn, As and SO42" that are removed were compared using linear correlation analyses. Examining the output from each cell for removal of these metals shows a marked correlation between Zn and S042" in the 2nd plant cell and Typha cell (r2= 0.8), before decreasing to 0.6 in the pond. This high positive correlation supports that the formation of ZnS (sphalerite) is an important aspect. Values for As are not as high. 

Figure 1 represents the layout of the treatment plant, which had a start up in 2006. It includes two wetlands, planted with typha, and an initial inorganic stage with a reception basin (of which the bottom is filled with limestone), a cascade aeration facility and a limestone channel.
