Abstract

Suspended sediment was isolated from water samples collected from the Mississippi River at Thebes, IL, eight times over a 5-year period from May 1988 through September 1993 in order to evaluate the transport of lipophilic halogenated organic compounds associated with the suspended sediment. Two hydrologic extremes were included-the 1988 drought and the 1993 flood. Halogenated organic compounds included polychlorinated biphenyls (PCBs), hexachlorobenzene, pentachloroanisole, DCPA (dacthal), trifluralin, aldrin, dieldrin, and chlordane components. Sediment transport of most of these organic compounds was substantially higher during the 1993 flood then at other sampling times. The extreme transports during the flood were due to unusually high concentrations of some contaminants on the suspended sediment, low to average concentrations of suspended sediment being transported, and unusually high water discharges.
