Summary
"Groundwater research report, WRC GRR 95-09."
Waste spills, landfill and storage facility leaks, and recharged surface waters introduce substances over small areas to groundwater. Resulting substance distributions generally exhibit spatial and temporal vaiability due to geologic and source property variations. Knowledge of the transport and fate of contaminants in the subsurface environment is vital to successful groundwater quality management efforts that aim to protect "clean" groundwater and clean up "contaminated" groundwater. Defining the flow pattern (velocity magnitude and temporal and spatial variations) is key to determining contaminant concentration distributions and rates of movement.
