Coastal Plain Geophysical and Lithologic Logs
The following information is derived from a compilation of the hydrogeologic framework of Maryland’s Coastal Plain (MGS Open-File Report No. 12-02-20: Maryland Coastal Plain
Aquifer Information System: Hydrogeologic Framework).
The data was assembled as part of a long-term multi-phase investigation, conducted by the Maryland Geological Survey and the
U.S. Geological Survey, with funding support from the Maryland Department of the Environment. It was initiated in response to
recommendations of the 2004 Maryland Advisory Committee on the Management and Protection of the State’s Water Resources.
