National Geographic Information Systems (GIS) layer of SSAs Information on sole source aquifers (SSAs) is widely used in assessments under the National Environmental Policy Act and at the state and local level. However, some individual aquifers serve mostly municipal purposes. Researchers have identified a previously undiscovered aquifer in southwest Texas. Aquifers covered by less permeable formations, such as clay, are confined under artesian pressure. Local aquifer: Not all groundwater sites have been associated with a local aquifer. The Texas Water Development Board (TWDB) specifically disclaims any and all liability for any claims or damages that may result from providing these data. Elevation (ft) Well Depth (ft) Water Level Observation Type. The aquifer also feeds several well-known recreational springs and underlies some of Texas most environmentally sensitive areas. Water quality is generally good northeast of the San Antonio River basin, but deteriorates to the southwest. Sandstone aquifers can be highly productive and provide large volumes of water. storage and recovery facility Water in the aquifer occurs in fractures, honeycomb zones (or intergranular pores), and solution channels in the Edwards and associated limestone formations of Cretaceous age. The information was collected by the U.S. Geological Survey and other agencies during the course of many years of study. Irrigation used the largest amount of ground water, 56,900 million gallons per day, foll, 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 component aquifers are Lower Tertiary, Upper Cretaceous, Lower Cretaceous, and Paleozoic. Now called the Maverick Basin Aquifer, it is known to be at least 3,000 square miles in area and averages 1,000 feet thick in most places. For an overview ofprincipalaquifers:The principal water-yielding aquifers of North America can be grouped into five types by rock type and location: unconsolidated and semiconsolidated sand and gravel aquifers, sandstone aquifers, carbonate-rock aquifers, aquifers in interbedded sandstone and carbonate rocks, and aquifers in igneous and metamorphic rocks. Extending from the Rio Grande in South Texas northeastward into Arkansas and Louisiana, the Carrizo-Wilcox aquifer provides water to all or parts of 66 counties. It is composed of several smaller aquifers contained within the Trinity Group.

Irrigation was the principal use in Medina and Uvalde counties. (Note that the National Aquifer Code uses a different numeric component than the geohydrologic unit names.). This dataset, published in 2003, contains the shallowest principal aquifers of the conterminous United States, Hawaii, Puerto Rico, and the U.S. Virgin Islands, portrayed as polygons. Elsewhere, water from the Trinity Aquifer is used primarily for municipal and domestic supply. Several agencies are investigating playa recharge and agricultural re-use projects over the aquifer. Igneous and metamorphic-rock aquifers can be grouped into two categories: crystalline-rock and volcanic-rock. Texas Gulf Coast Groundwater and Land Subsidence Over Forty Years of Research in the Houston-Galveston Region. This website compiles USGS resources and data related to principal aquifers including Aquifer Basics, principal aquifers maps and GIS data, and the National Aquifer Code Reference List. Unconsolidated sand and gravel aquifers are characterized by intergranular porosity and all contain water primarily under unconfined, or water-table, conditions. (in error) Northern Great Plains aquifer system, Some revisions to the lists of valid States, this code, and reference list were added to the NWIS Site File and toNWISWebwith the release of NWIS 4.5 in 2005; see the WMA Technical Memo "NWIS 4.5 -- Assigning National Aquifer Codes in the Ground Water Site Inventory (GWSI) for the NWIS 4.5 Release.". The Geologic Atlas of Texas illustrates the surface extent of geologic formations (and aquifers) across the state. This map, which was derived fromGround Water Atlas of the United Statesdata (published as part of the National Atlas in 1998, revised 2003) indicates the areal extent of the uppermost principal aquifers on a national scale. In Harris, Galveston, Fort Bend, Jasper, and Wharton counties, water level declines of as much as 350 feet have led to land subsidence. These aquifers consist of limestones, sands, clays, gravels, and conglomerates. In general, groundwater is fresh but very hard in the outcrop of the aquifer. Although referred to differently in different parts of the state, they include the Antlers, Glen Rose, Paluxy, Twin Mountains, Travis Peak, Hensell, and Hosston aquifers. Although the Carrizo-Wilcox Aquifer reaches 3,000 feet in thickness, the freshwater saturated thickness of the sands averages 670 feet. The aquifer is comprised of the Twin Mountains, Glen Rose, Paluxy, Hosston, and Hensell formations. We are the premier source for trusted information about Texas. Below are publications associated with national aquifers. These data delineate the areal extent of the alluvial and glacial aquifers as defined in The Ground Water Atlas of The United States. Aquifers in carbonate rocks are most extensive in the eastern U.S. The Ogallala Aquifer is the largest aquifer in the United States and is a major aquifer of Texas underlying much of the High Plains region.

It consists of the Hooper, Simsboro, and Calvert Bluff formations of the Wilcox Group and the overlying Carrizo Formation of the Claiborne Group. Near the plateaus edge, flow is toward the main streams, where the water issues from springs. The surficial aquifer in the Coastal Plain of these States should be included in the Northern Atlantic Coastal Plain aquifer system. The Edwards aquifer in the Balcones fault zone of southcentral Texas is one of the most permeable and most productive aquifers in the world. Water from the Antlers portion is used mainly for irrigation in the outcrop area of North and Central Texas. However, because these aquifers extend over large areas, large volumes of water can be withdrawn. It consists of the Hooper, Simsboro, and Calvert Bluff formations of the Wilcox Group and the overlying Carrizo Formation of the Claiborne Group. Computer models of the northern and southern portions of the Ogallala aquifer were completed by the Texas Water Development Board and its contractor. The Ogallala Formation of late Miocene to early Pliocene age consists of heterogeneous sequen-ces of coarse-grained sand and gravel in the lower part, grading upward into clay, silt, and fine sand. For the distance tool click points on the map to build line segments to measure and double click to complete the measurement. 1, Total pumping estimates for the Ogallala, Edwards-Trinity (High Plains), and Dockum aquifers in High Plains UWCD No. This is an important step in planning for water in Texas and Bastrop County for the next 50 years. The aquifer is used for municipal, industrial, and irrigation purposes. These aquifers span many counties and most of the major aquifers extend beyond Texas borders. This is one in a series of reports the Comptroller has prepared on water in Texas.

The Maverick Aquifer, as it's been named, lies more than a mile deep under parts of Maverick, Uvalde, Dimmit and Kinney Counties. It consists of sandstone and limestone formations of the Trinity formations, and limestones and dolomites of the Edwards and associated limestone formations. In 2008, about 72 percent of pumpage from the aquifer was for municipal use. Official websites use .gov Water Quality Available. Water quality in the Carrizo-Wilcox Aquifer shows isolated areas of slightly saline to moderately saline groundwater in the eastern and central portions of the aquifer and more widespread areas of slightly to moderately saline groundwater in the southwest. 9999--Areas that are not a national aquifer. Click any position on the map to reveal attributes for a specific location. Water-use data collected using this list of aquifers will be published in. In 2008, almost 96 percent of the water pumped from the Ogallala was used for irrigation. El Paso, however, has reduced its use of groundwater from the Hueco Bolson since 1989, and observation wells indicate that water levels have stabilized. The name of N600NECRSN was changedfrom "New England crystalline-rock aquifers" to "New York and New England crystalline-rock aquifers" to better reflect the geographic extent (January 2015). Texas Water Development Board works best with JavaScript enabled. Throughout much of the aquifer, groundwater withdrawals exceed the amount of recharge, and water levels have declined fairly consistently through time. Guadalupe runs dry with rainfall scarce. The aquifer now provides approximately 90 percent of the citys drinking water. This aquifer underlies the Edwards Plateau, extending through 40 counties from the Hill Country of Central Texas westward to the Trans-Pecos region. If you have any questions or concerns regarding the material on this page, please contact the Comptrollers Data Analysis and Transparency Division. The Hueco Bolson, located on the eastern side of the Franklin Mountains, consists of up to 9,000 feet of clay, silt, sand, and gravel and is an important source of drinking water for both El Paso and Juarez, Mexico. Declines continue in Ward County due to increased municipal and industrial pumping. Most of the water pumped from the aquifer is used for irrigation. About 60 percent of the approximately 16 million acre-feet of water used yearly in Texas is derived from underground formations that make up 9 major and 22 minor aquifers.
