One of the major environmental quality problems facing the Corps of Engineers, the dredging industry, and those responsible for maintenance and operation of harbors and waterways in the U.S. is that of determining the best overall method for dredged material disposal. Because chemical contaminants in many dredged sediments have exceeded the arbitrary criteria developed by some water pollution control regulatory agencies, alternate methods of dredged material disposal have been adopted. This has, in many instances, increased the cost of disposal. This situation led to creation of the Corps of Engineer Dredged Material Research Program (DMRP), which was specifically designed to provide information to be used in determining the best overall method of disposal of dredged sediments. The DMRP project at Galveston consisted of three major components: studies on the currents, geology and fate of dredged sediments deposited at the Galveston site; water-quality studies on the water column and sediments before, during and after dredged material disposal operations; and studies on the effect of dredged material disposal on the numbers and types of aquatic organisms present in the disposal area.
