Basic Data Report 22


Six exploratory test wells were drilled in Southern Maryland to obtain hydrogeologic data for the Upper Patapsco and Lower Patapsco aquifers. Information collected from the test wells includes lithologic descriptions of sediments; biostratigraphic analyses using fossil pollen, spores, and plankton; geophysical logs; hydraulic characteristics; water-quality analyses; and water-level data. The hydrogeologic data were used in a regional study of the water-supply potential of the Coastal Plain aquifers in Calvert, Charles, and St. Mary’s Counties, Maryland. This report documents the hydrogeologic data collected from the wells, and includes brief descriptions of associated drilling, construction, and data-collection procedures.
