Simulation of ground-water flow of the coastal plain aquifers in parts of Maryland, Delaware, and the District of Columbia

Geomorphic processes and the aquatic habitat of the Redwood Creek basin were studied extensively between 1973 and 1983. This volume contains 22 separate articles by 32 investigators who studied geology, major storms, timber harvesting and its role on accelerating erosion, mass movement, fluvial erosion, sediment transport and storage, stream channel response to storms and landuse, stream habitat, and stream chemistry. This research describes a rapidly eroding landscape that is sensitive to effects of both landuse and major storms.

Ground-water flow and the potential effects of remediation at Graces Quarters, Aberdeen Proving Ground, Maryland

Ground water in the east-central part of Graces Quarters, a former open-air chemical-agent test facility at Aberdeen Proving Ground, Maryland, is contaminated with chlorinated volatile organic compounds. The U.S. Geological Survey's finite- difference model was used to help understand ground-water flow and simulate the effects of alternative remedial actions to clean up the ground water. Scenarios to simulate unstressed conditions and three extraction well con- figurations were used to compare alternative remedial actions on the contaminant plume. The scenarios indicate that contaminants could migrate from their present location to wetland areas within 10 years under unstressed conditions. Pumping 7 gal/min (gallons per minute) from one well upgradient of the plume will not result in containment or removal of the highest contaminant concentrations. Pumping 7 gal/min from three wells along the central axis of the plume should result in containment and removal of dissolved contami- nants, as should pumping 7 gal/min from three wells at the leading edge of the plume while injecting 7 gal/min back into an upgradient well.
