This Final Report describes the details of Environmental Security Technology Certification Program Project ER-200825 In Situ Wetland Restoration Demonstration. The overall objective was to field demonstrate and validate activated carbon AC in situ wetland remediation technologies which have been designed to sequester contaminants in wetlands without adversely impacting system ecology. The Field Demonstration was performed at Canal Creek, Aberdeen Proving Ground APG, Aberdeen, Maryland. This report includes discussion of quantitative and qualitative performance objectives, information about the study area, pre-demonstration testing, and the implementation and monitoring of the demonstration. Performance assessment criteria and methods, evaluation of the demonstration results, cost, potential implementation issues, and uncertainties associated with these findings are also discussed. The field demonstration was designed to evaluate three potential AC remediation technologies two pelletized A C products, a powder AC slurry, and an engineered manufactured soil cover system. The efficacy to treat hydric soils impacted by polychlorinated biphenylsPCBs was assessed via analyses of PCB pore water and tissue residue concentrations. The partitioning of PCBs from soil-to-pore water and from soil-to-benthic tissue was also evaluated. The uptake of nutrients by plants was measured for each of the treatment types.
