Description
Summary:The Biological and Chemical Oceanography Branch of the Naval Ocean Research and Development Activity conducted a three-phase study to assess the environmental effects of depositing 2,907,750 cubic yards of dredged material at the Jacksonville Harbor ocean disposal site designated for such purposes by the Environmental Protection Agency. Approximately 56% (1,637,000 cubic yards) of this material was dredged from the U.S. Naval Station, Mayport, FL. Distribution of dredged material at the disposal site was found to be both vertically and horizontally heterogeneous. Changes in bottom topography, coupled with significant increases of certain heavy metal (Ni, Cu, Pb, Zn, and Cr) within the disposal site, can be attributed to accumulation of dredged material during the period of investigation. A standard elutriate test indicated that heavy metals were bound to the Mayport dredged material and would not be readily released to the water column during disposal operations.
