Description:
In this SITE demonstration, phytoremediation technology was applied to contaminated dredged materials from the Jones Island Confined Disposal Facility (CDF) located in Milwaukee Harbor, Wisconsin. The Jones Island CDF receives dredged materials from normal maintenance of Milwaukee's waterways and tributaries, and has done so for many years. Like many CDFs across the country, Jones Island faces the dilemma of steady inputs and no feasible alternative for expansion. The U.S. Army Corps of Engineers (USACE), in partnership with the Milwaukee Port Authority, is exploring an extensive range of beneficial reuse options for the dredged material, from building materials to road fill to landscaping soil. However, a portion of the material must be remediated before it can be beneficially reused.
Aged dredged material at Jones Island is heterogeneous in composition because it comes from waterway sources over a wide area over a period of many years. Some dredged materials contain USEPA listed wastes from industrial discharge, spills, and urban run-off in widely varying concentrations. Dredged materials used in the SITE demonstration were impacted by polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and diesel-range organics (DRO).
The goal of this demonstration project was to evaluate the ability of four different treatment schemes, three plant-based and one microbe-based, in attaining residual contaminant levels for PAHs, PCBs and DRO consistent with the most applicable Wisconsin Department of Natural Resources (WDNR) requirements for beneficial use of dredged materials.
