Chemical characteristics of grain coatings in a Coastal Plain sandy aquifer on the Eastern Shore of Virginia were investigated where sediments have been exposed to distinct groundwater redox conditions. Dissolved O2 was 5.0 to 10.6 mg L 1 in the regionally extensive aerobic groundwater, whereas in a narrow leachate plume it was only <0.001 to 0.9 mg L . The amount of dissolved Fe in the aerobic groundwater was only 0.005 to 0.01 mg L , but it was 12 to 47 mg L 1 in the anaerobic zone. The… CONTINUE READING
