The data in Table 12.4 provide a summary of chemical and physical characteristics of influent and effluent water from constructed wetlands at Tennessee Valley Authority (TVA) facilities. Water quality generally improved in all cases, and most met the state effluent guidelines for total Fe < 3.0 mg L"1, total Mn < 2.0 mg L-1, pH 6.0-9.0, and nonfilterable residues (NFR) < 35.0 mg L 1. These data also indicate that wetlands are more effective in the removal of Fe2+ than Mn2+.

During the treatment of heavy-metal containing solutions, the use of constmcted wetlands is thought of as an easy technologieal alternative when compared with conventional treatment methods. The term wetland is used to characterize natural ecosystems partially or totally flooded during the year. Observations about the ability of natural wetlands to change the quality of water led to the development of artificial ecosystems able to treat several classes of wastewater. Those ecosystems are called constructed wetlands, and the main...
