Arsenic Distribution and Occurrence In Ground Water from Coastal Plain Aquifers In Maryland
The distribution of dissolved arsenic and the age of water in the Aquia and Piney Point/Nanjemoy aquifers suggest that arsenic is derived from a natural source within the aquifers, rather than anthropomorphic contamination. Furthermore, no arsenic-bearing minerals are present in these aquifers in sufficient quantities to provide a likely source of dissolved arsenic in elevated concentrations. Possible geologic and geochemical factors affecting dissolved arsenic concentrations in ground water are discussed.
David D. Drummond, Maryland Geological Survey David D. Drummond received his Bachelor of Arts Degree in Geochemistry from the University of Colorado at Boulder in 1977, and his Master of Science Degree in Geology from the George Washington University in 1987. He has worked at the Maryland Geological Survey since 1978 in the Hydrogeology Program. His research includes hydrostratigraphy, ground-water flow and contamination, and water-supply evaluation of the Coastal Plain aquifers in Maryland. Mr. Drummond has developed digital computer models to simulate ground-water flow, solute transport, and particle tracking, and has used a GIS extensively to analyze hydrogeologic data.
