    • Hydrogeologic unit map for Wake County, North Carolina

    Metadata Updated: January 6, 2026

    A hydrogeologic unit map was created for Wake County, North Carolina by grouping geologic map units from Clark and others, 2004 based on their water-bearing potential. The water-bearing potential of the units was determined from rock origin, composition, and texture as described in Daniel (1989) and Daniel and Payne (1990) for the Piedmont and Blue Ridge Provinces of North Carolina. A layer file is also included to provide the map symbology used in the report.
