Project Chief: Hydrogeology and Groundwater Quality of the Anacostia River

Groundwater hydrogeology in the lower Anacostia tidal watershed is not well characterized, and is possibly a source of contaminants to the river. Because of the urban nature of the watershed and the long history of industrial and residential development in the area, it is likely that Groundwater in the area is contaminated. However, little is known about the types of non-point source contaminants in the Groundwater, the characteristics of Groundwater flow, or the volumetric flux of Groundwater and associated contaminants to the river. Because of the many modifications to the river system (including bulkheads, dredging, filling, engineered wetlands, storm drains, and leaky infrastructure), Groundwater interactions with the river are expected to be complex and difficult to characterize. It is therefore important to use a wide variety of investigative tools to help characterize the Groundwater flow system, the Groundwater quality, and the Groundwater / surface-water interactions.

The overall goal of the proposed project is to develop an understanding of the hydrogeologic framework, to determine the extent of Groundwater / surface-water interactions, and to estimate the contributions of contaminants from the Groundwater to the lower tidal Anacostia River.
