About this file
This file is a remediation map prepared for the Milwaukee Estuary Area of Concern in Milwaukee, Wisconsin, depicting Remediation Target Areas for the Downtown Reach Alternative 3 project. The map illustrates the geographic boundaries and extent of contaminated sediment requiring remediation based on specific pollution thresholds, including total polychlorinated biphenyls (PCBs) exceeding 1 milligram per kilogram, metals such as chromium, mercury, or lead, or total polycyclic aromatic hydrocarbons (PAHs) exceeding three times Probable Effects Concentrations. The project area encompasses the Milwaukee River downtown reach, with remediation targets delineated against the Toxic Substances Control Act (TSCA) dredge limits of 50 milligrams per kilogram, Federal Navigation Channel boundaries maintained by the United States Army Corps of Engineers, and existing utilities infrastructure. The map provides spatial reference through street names, landmarks including Milwaukee Bay, and directional flow indicators for both the Milwaukee River and Menomonee River.
The document serves as a technical reference tool for environmental remediation planning and bidder understanding of the contaminated sediment areas requiring treatment or removal. This map supports decision-making regarding remediation strategy and scope definition for the Milwaukee River estuary cleanup initiative, enabling contractors to assess project complexity and site conditions relevant to proposal development and cost estimation.
