The exposure assessment component of the aquatic portion of the Field Verification Program (FVP) relates the source input of the dredged material contaminants to the corresponding concentration distributions in space and time in the vicinity of the disposal mound. The specific objectives for this component are: (1) determine the environmental exposure field at the biological effects measurement stations in the water column (polagic zone), in the sediments (benthic zone), and at the near-bottom/sediment-water interface (epibenthic zone), (2) relate the source (dredge disposal mound) to the near-field exposure measurements using process models for the vertical transport of contaminants and particulate materials, and (3) determine the environmental processes controlling contaminant phase partitioning.
