Evaluation of Upland Disposal of Richmond Harbor, California, Sediment from Santa Fe Channel

Abstract : This report describes testing and evaluation performed by the Environmental Laboratory of the U.S. Army Engineer Waterways Experiment Station (WES) on sediment from the Santa Fe Channel of Richmond Harbor, California. Test protocols from the Corps' Management Strategy for Disposal of Dredged Material were used in the present evaluation to determine the potential for migration of contaminants into the effluent, surface runoff, and leachates at an undetermined upland disposal site. The upland site would be managed such that plants and animals would not be allowed to colonize the site. Therefore, plant and animal bioassays were not performed. Sediment was collected from Santa Fe Channel from core depths to -38 ft and transported to the WES for testing. Santa Fe Channel sediment metal concentrations were found to be in the range of those found in normal agricultural soils with the exception of nickel. Santa Fe Channel sediment contained nickel Contaminant migration, Sediment testing, Contaminated sediments, Upland disposal. Dredged material, concentrations at the maximum concentration allowed in soils for agricultural production.
