ANAEROBIC COMPOST CONSTRUCTED WETLANDS SYSTEM TECHNOLOGY - SITE ITER
Tetra Tech EM Inc. ANAEROBIC COMPOST CONSTRUCTED WETLANDS SYSTEM TECHNOLOGY - SITE ITER. U.S. Environmental Protection Agency, Washington, DC, EPA/540/R-02/506, 2003.
In Fall 1994, anaerobic compost wetlands in both upflow and downflow configurations were constructed adjacent to and received drainage from the Burleigh Tunnel, which forms part of the Clear Creek/Central City Superfund site. The systems were operated over a 3 year period. The effectiveness of treatment by the CWS was evaluated by comparing the concentration of zinc and other metals from corresponding influent and effluent analyses. The upflow CWS removed an average of 93 percent of the zinc during the second and third years. The downflow CWS removed an average of 77.4 percent of zinc during the first year and 70 percent during the second year. (Flow was discontinued to the downflow system in the third year). Complete data were published in the Technology Evaluation Report (TER) for the evaluation and are available from EPA.
