The Wetlands Demonstration Project 1 (WDP1) facility was an anaerobic, subsurface flow wetland, whereas the Colorado Tailings (CT) facility was a lime-added, aerobic system. At both sites, a significant fraction of each metal of concern (Cu, Cd, Zn, Fe, and Mn) existed in particulate form in some parts of the treatment system. The anaerobic WDP1 wetland removed dissolved metals to very low levels, but had mixed success in filtering out fine-grained sulfide precipitates of Cu, Cd and Zn. The CT wetland showed better capacity to remove particulate metals. Based on these two case studies, the importance of obtaining both filtered and unfiltered (total recoverable) samples at treatment wetlands is stressed.
