Due to the depth and areal extent of the aquifer-system units, direct measurement was not possible. Instead, interpretations of the deeper stratigraphy and hydrostratigraphy were developed from multiple types of data collected at boreholes of various kinds, including monitor wells, boreholes, drilled corehole samples, and drill cuttings. Types of data from the boreholes include water level, geophysical logs, lithologic logs, paleontological age data, particle-size analyses, and analyses of the effects of aquifer tests. These data collected from the boreholes and water wells were used to construct the hydrostratigraphic correlations from borehole to borehole across the Atlantic Coastal Plain of North Carolina and South Carolina. See the methods of investigation section of Chapter B of the report for more information regarding how these data were used. See Figure B3 for a map of the borehole locations. See Appendix B1 for table of borehole data values. See Appendix B2 for core description of corehole example ORG-393 (#68). Gellici, J.A., Lautier, J.C., Chapter B.
