Abstract: The U.S. Army Corps of Engineers, Detroit District (USACE) retained RTI Laboratories, Inc. (RTI) as a contractor to perform sediment sampling services within the Harbor and Federal Navigation Channel in Kewaunee, Wisconsin (Site) in response to and in accordance with the Detroit District’s Request for Proposal (RFP) and Statement of Work (SOW) received on 26 June 2014. This project is part of an assessment of sediment quality within the navigation channel of the site. This project involves collection of sediment samples from shoaling within the Navigation Channels of the Harbor. This information will be used by the District and its clients to select the proper sediment dredging practices as well as monitor any potential migration of contaminants. RTI and its subcontractor, Coleman Engineering Company, provided sediment sampling services using Vibra-core sampling devices using a pontoon boat at the Site. The scope of the work was to sample predetermined locations within the Harbor along the Site as shown in Figure 3. The sampling crew (RTI team) mobilized and assembled at the Kewaunee boat access just west of Main Street on Thursday, 14 August 2014 in the afternoon. The team launched and began sampling from the western stations, moving east to the stations around the Harbor entrance. The RTI team consisted of three (3) people: Matthew Tuynman from RTI, and 2 operators from Coleman Engineering. Coleman was retained by RTI to provide and operate sediment sampling equipment (pontoon boat and Vibra-core sampler). Eleven samples were collected from the navigation channel at Kewaunee Harbor in two days. Sampling, sample handling, and analytical procedures were conducted in accordance with the Scope of Work (SOW) and specifications of the current USACE Contract W911XK-11-D-0005 Delivery Order 0028, in addition to “Methods for Evaluating Solid Waste”, 3rd ED, U.S. EPA No. SW-846, DoD Quality Systems Manual v5.0, and “Description of Soils (Visual-Manual Procedure)”, ASTM D 2488-69. A total of eleven (11) sediment samples were collected during two days of sampling. All samples were collected within the designated navigation channel from locations identified in the maps supplied by the District and included in Appendix A. RTI surveyed the harbor area for other areas of shoaling and some sample locations were adjusted from the original SOW. Final sample locations are provided in Appendix C, showing the actual sample locations. This report provides documentation of the field survey and describes the field activities that occurred, the samples collected, and the conditions encountered during the survey. This report also includes the overview maps and proposed sample locations in Appendix A. Appendix B – Table 1 presents the sediment chemistry analysis for the sediment samples collected. Table 2 presents the sediment grain size analysis for the sediment samples. RTI Team maintained a field logbook for this project. A typed copy of the field logbook form and the compiled notes are included as Appendix C along with maps of the final sampling locations. The compiled boring logs are presented in Appendix D. Photographs of the samples and activities are included in Appendix E. Appendix F contains the Analytical Report, with chain-of-custody forms and the Grain Size Analysis Report from TestAmerica Laboratories, a Wisconsin Certified environmental lab.
