Coastal lowlands aquifer system
The Coastal lowlands aquifer system consists of unconsolidated deposits of Tertiary and Quaternary age that yield large quantities of water for public, industrial, and agricultural uses. - Oklahoma, and Texas (Chapter E)
- Arkansas, Louisiana, and Mississippi (Chapter F)
- Alabama, Florida, Georgia, and South Carolina (Chapter G)
Texas coastal uplands aquifer system
The Texas coastal uplands aquifer system underlies an area of about 48,000 square miles in the upper part of the Coastal Plain. The aquifer system consists of unconsolidated deposits of early Teriary age that yield large quantities of water for agicultural, public, and industral supplies. - Oklahoma, and Texas (Chapter E)
Mississippi embayment aquifer system
The Mississippi embayment aquifer system is more than 5,000 feet thick in a wide area of south-central Louisiana and southwestern Mississippi. - Arkansas, Louisiana, and Mississippi (Chapter F)
- Kansas, Missouri, and Nebraska (Chapter D)
- Illinois, Indiana, Kentucky, Ohio, and Tennessee (Chapter K)
Southeastern Coastal Plain aquifer system
The rocks comprising the five regional aquifers and three confining units of the Southeastern Coastal Plain aquifer system are exposed at the land surface as a seried of curved bands. The classic rocks of the aquifer system yield moderte volumes of water. - Arkansas, Louisiana, and Mississippi (Chapter F)
- Alabama, Florida, Georgia, and South Carolina (Chapter G)
- Illinois, Indiana, Kentucky, Ohio, and Tennessee (Chapter K)
Northern Atlantic Coastal Plain aquifer system
The aquifer system underlies an area of about 50,000 square miles. The western limit of the aquifer system is the landward edge of water-yielding Coastal Plain strata where they pinch out against crystalline rocks of the Piedmont Physiographic Province at the Fall Line. Unconsolidated sands compose the surficial aquifer, which is the uppermost water-yielding part of the aquifer system. - Science

Unconsolidated and semiconsolidated sand and gravel aquifers
Unconsolidated sand and gravel aquifers are characterized by intergranular porosity and all contain water primarily under unconfined, or water-table, conditions. They are grouped into four categories: basin-fill, blanket sand and gravel, glacial-deposit, and stream-valley aquifers. Semiconsolidated aquifers consist of semiconsolidated sand interbedded with silt, clay, and minor carbonate rocks... - Publications

Ground Water Atlas of the United States
PrefaceThe Ground Water Atlas of the United States presents a comprehensive summary of the Nation's ground-water resources and is a basic reference for the location, geography, geology, and hydrologic characteristics of the major aquifers in the Nation. The information was collected by the U.S. Geological Survey and other agencies during the course of many years of study. Results of the Regional APrincipal aquifers [of the United States]
