Water Quality Research Program: Studies on the Adsorption/Desorption and Microbial Mobilization of Contaminants from Sediments in Corps of Engineers Reservoir Projects
Abstract
Laboratory studies were conducted to meet three recommendations developed in a previous technical report on sediment-water interactions and contaminants in Corps of Engineers reservoir projects (Technical Report E-89-2). Each of three aspects of sediment-water interaction are addressed in a separate part of the report. These investigations include examination of the effects of adsorption kinetics, oxidation status of suspended sediments in the water column, and sediment concentration on interactions of trace metals with suspended sediment; examination of the effects of low sediment concentrations in the water column on loading kinetics, desorption kinetics, the distribution coefficient, and sequential desorption of low levels of an organic contaminant; and description of an investigation conducted to determine whether copper flux from reservoir sediments is enhanced in proportion to the microbial release of dissolved organic matter from sediment deposits.
