The objective of the Wetland System Evaluation Project was to develop a design and performance matrix for known pollutants in surface-flow and subsurface-flow constructed wetland systems, including biochemical oxygen demand (BOD), total suspended solids (TSS), nutrients, pathogens, and wastewater-derived organic compounds (WDOCs). This objective also includes the identification of specific chemicals to best represent or act as surrogates for various classes of pollutants and WDOCs. Although this project is not expected to answer all of the many questions related to the use of wetlands for water quality improvement, it is intended to provide an assessment of the current state of our knowledge about the effectiveness of these natural treatment systems to meet water quality goals.

Research and analyses undertaken by this project supports continuing consideration of constructed wetlands as an option for providing polishing treatment to protect aquatic ecosystems and potable water supplies. The findings of the project indicate that constructed wetlands can be used to consistently and cost effectively reduce concentrations of conventional pollutants remaining in reclaimed wastewaters and can also further reduce levels of certain WDOCs.
