List of semiconsolidated sand and gravel aquifers Completed

By Water Resources Mission Area March 8, 2021

Semiconsolidated aquifers of the United States, which consist of semiconsolidated sand interbedded with silt, clay, and minor carbonate rocks.

To learn more, visit the Unconsolidated and Semiconsolidated Sand and Gravel Aquifers webpage for an overview, or access more extensive information from the Ground Water Atlas of the United States (USGS Hydrologic Atlas 730) by clicking on an individual region/chapter below.

 

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.

 

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.

 

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.


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.

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.

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...

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 A
