Abstract: This report presents field data and test results from sediment and water collection activities in Big Fishweir Creek, Jacksonville, Florida, that occurred in October 2019 by Water & Air Research, Inc. (Water & Air). The purpose of this sampling effort was to provide information required by decision makers to evaluate future dredging activities within the creek and to help determine the appropriate method of sediment disposal, which may be placement into nearby wetlands to restore elevations for storm resiliency and/or landfill disposal. Before dredging can occur, sediments and elutriates needed to be tested and compared to sediment and water quality criteria to determine if they contained elevated concentrations of contaminants of concern that may alter the method of placement or disposal of the dredged sediment. Geotechnical vibracores were also collected for testing by the U.S. Army Corps of Engineers (USACE) Jacksonville District. Sampling locations within Big Fishweir Creek are presented on Figure 1. Prior to initiating field work, a Quality Assurance Project Plan (QAPP) was developed and approved by the U.S. Army Corps of Engineers, Jacksonville District. The sampling and laboratory test procedures used followed those specified in the QAPP (Appendix A). While some problems were encountered, all were successfully resolved. Two problems were notable: 1) The shallowness of the area, which hindered the sampling schedule of activities. 2) Unanticipated elevated detection limits for some contaminants of concern. Although some problems were encountered, all data were judged acceptable for project needs.
