The Great Lakes National Program Office (GLNPO) selected environmental dredging as the remedy of choice for remediation and cleanup of the Ottawa River (near Toledo, Ohio) where the sediments are contaminated with PCBs, PAHs, and Pb. A Phase 1 baseline assessment of the site was conducted in the summer and fall of 2009 and the spring of 2010 prior to the onset of dredging. In partnership with GLNPO, EPA implemented a comprehensive sustained research program (2009-2015) for the Ottawa River remediation project to evaluate and optimize the assessment and monitoring methods conceived and developed along physical, biological, and chemical lines of evidence that can be used in a weight-of-evidence framework to assess sediment remedies. This report summarizes the site characterization and data collection tasks carried out in Phase 1 prior to the onset of environmental dredging activities. Additional data reports will follow that document the subsequent phases of the Ottawa River project. https://nepis.epa.gov/Exe/ZyPURL.cgi?Dockey=P100SUO2.txt
