Joint Base Charleston (JBC) is located on the west bank of the Cooper River in and near the mouth of Goose Creek in Berkeley County, South Carolina. JBC encompasses more than 17,000 acres of land, with 10,000 acres of forest and wetlands, 16-plus miles of waterfront, four deep-water piers, 38.2 miles of railroad, and 292 miles of road. Charleston Harbor is on the Cooper River downstream from JBC. The harbor is a natural tidal estuary covering an area of approximately 14 square miles and is formed by the confluence of the Ashley, Cooper, and Wando rivers at Charleston. JBC is a Logistics, Transportation and Engineering Hub and the worldwide leader in moving people, vehicles, munitions, and supplies via air, land, sea, and rail for the Department of Defense. The navigation channels support the associated Department of Defense port facility. As such, it is one of the busiest surface ports in the continental United States’ defense transportation system. Maintenance dredging is required to maintain navigable conditions at JBC facilities. Sediment evaluations were needed prior to dredging the pier areas to provide information required for authorization of dredge material disposal in accordance with Sections 401 and 404 of the Clean Water Act for discharge of materials into waters. ANAMAR was contracted by USACE to perform sampling activities in the project area. ANAMAR coordinated and directed operations for this project, subcontracted vibracore sampling and laboratory analyses, and prepared final report deliverables. ANAMAR reviewed all data and produced a report summarizing the results of the physical and chemical analysis of sediment samples collected from the project area. |
