Contaminants move preferentially along zones of higher permeability.
Accordingly, the permeability of such discrete zones determines, in part, the rate at which contaminants move through the ground-water system. Constrain the flow system with ground-water ages obtained from chlorofluorocarbon analyses. Use geochemical modeling to determine appropriate simplifications that can be made. Information on appropriate simplifications will be useful at similarly contaminated sites where data are limited and may help determine the types of data that need to be collected. Develop improved instrumentation and more efficient data-collection techniques to determine rates of uptake of dissolved metals in the hyporheic zone.
