An understanding of the hydrology and the contaminant distribution and fate in the wetlands is needed to evaluate feasible ground-water remediation methods. Many processes, however, could act to naturally attenuate the ground-water contaminants in the wetland sediments. The purpose of this study is to evaluate the factors controlling the fate and mobility of the contaminants in the wetland so that natural attenuation can be evaluated as a possible remediation method.
Objectives Define the hydrogeologic framework in Canal Creek area.
Determine the nature, extent, behavior, and as nearly as feasible, the sources of contamination in the ground water. Evaluate the hydrologic and hydrogeochemical effects of relevant remedial activities. Determine the extent of surface-water contamination and the amount of offsite migration. Determine contaminant fate and mobility in a tidal marsh at West Branch Canal Creek. Define ground-water flowpaths and interactions between the ground water, marsh, and surface water.
