    • A Surficial Hydrogeologic Framework for the Mid-Atlantic Coastal Plain

    Metadata Updated: January 16, 2026

    The hydrogeologic framework was developed from a combination of the physiography and the predominant texture of surficial geologic units in the Mid-Atlantic Coastal Plain. It describes the primary natural physical factors that affect the flow and chemistry of shallow ground water and small streams in the Mid-Atlantic Coastal Plain. Seven hydrogeologic subregions were defined. Some of the subregions correspond directly to the physiographic subprovinces of the region; others were generalized within subprovinces based on sediment texture. For more information, see U. S. Geological Survey Professional Paper 1680.
