The source and fate of many pollutant substances in the Nation's largest river system are closely tied to suspended sediment. Accurate prediction of the fate of these pollutants will require more than our present understanding of the interactions between sediments and pollutants and the ways in which large rivers store and remobilize suspended sediment. Project objectives are to define and understand: (1) processes by which pollutant substances, organic and inorganic, are adsorbed onto sediment particles, (2) downstream mixing of pollutants below the confluence of large tributaries with the mainstem, and (3) seasonal storage and remobilization of sediment and pollutants, in the Mississippi River system.
