Most of the carbonate-rock aquifers consist of limestone, but dolomite and marble locally yield water. Historically, Texas has had a wealth of fresh to slightly saline water, which underlies more than 81 percent of the state. Water Quality Available. This list of national principal aquifer codes and names are fixed values assigned by the National Water Information System(NWIS). A major aquifer is generally defined as supplying large quantities of water in large areas of the state. 600--Igneous and metamorphic-rock aquifers. Water quality is generally good northeast of the San Antonio River basin, but deteriorates to the southwest. Freshwater saturated thickness averages 95 feet. The aquifer is comprised of the Twin Mountains, Glen Rose, Paluxy, Hosston, and Hensell formations. The desired future conditions provide the foundation for estimating the amount of groundwater available to the region. The appropriate component aquifer should be used instead of Northern Great Plains. 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. Groundwater also supplies about 35 percent of the municipal needs of the state. The map layer was developed as part of the effort to produce the maps published at 1:2,500,000 in the printed series Ground Water Atlas of the United States. For the location tool click on the map to get coordinates for a particular location. About 75 percent of this water is used for irrigation, with irrigators withdrawing most of this water from the Ogallala Aquifer alone (74 percent of all groundwater used for irrigation, or 4.5 million acre-feet per year). Texas State Historical Association (TSHA). Until recently, San Antonio was one of the largest cities in the world that relied solely on a single groundwater source for its municipal supply. Throughout much of the aquifer, groundwater withdrawals exceed the amount of recharge, and water levels have declined fairly consistently through time. Natural salt pollution in the upper reaches of the Red and Brazos river basins precludes the full utilization of these water resources. This is an important step in planning for water in Texas and Bastrop County for the next 50 years. Municpal water use in 2008 accounted for 87 percent of total use from the Hueco-Mesilla Bolson. Surficial deposits of glacial origin (New Jersey) should be included in Sand and gravel aquifers (glaciated regions). Texas has three ASR systems.

Aquifers are shown in the States of Maine, Vermont, New Hampshire, Connecticut, Massachusetts, Rhode Island, New Jersey, New York, Pennsylvania, Ohio, Indiana, Michigan, Wisconsin, Illinois, Minnesota, Iowa, Missouri, Kansas, Nebraska, South Dakota, North Dakota, and Montana. The Texas Water Development Board (TWDB) specifically disclaims any and all liability for any claims or damages that may result from providing these data. Groundwater movement in sandstone aquifers primarily is along bedding planes, but joints and fractures provide avenues for the vertical movement of water. Total dissolved solids increase from less than 1,000 milligrams per liter in the east and southeast to between 1,000 and 5,000 milligrams per liter, or slightly to moderately saline, as the depth to the aquifer increases. Total ground-water withdrawals were 76,500 million gallons per day, or 85,800 thousand acre-feet per year for these three uses. 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. . The information was collected by the U.S. Geological Survey and other agencies during the course of many years of study. Individual accumulations vary greatly in thickness, but most of the Seymour is less than 100 feet.

Aquifers are identified by a geohydrologic unit code (a three-digit number related to the age of the formation, followed by a 4 or 5 character abbreviation for the geologic unit or aquifer name). The Trinity Aquifer consists of basal Cretaceous-age Trinity Group formations extending through 61 counties from the Red River in North Texas to the Hill Country of Central Texas. The U.S. Geological Survey prepared this dataset in cooperation with the Harris-Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, Lone Star Groundwater Conservation District, and Brazoria County Groun This list of national principal aquifer codes and names are fixed values assigned by the National Water Information System (NWIS). The component aquifers are Lower Tertiary, Upper Cretaceous, Lower Cretaceous, and Paleozoic. Spaces in crystalline rocks are microscopically small, few, and generally unconnected. Their combined freshwater saturated thickness averages about 600 feet in North Texas and about 1,900 feet in Central Texas. Irrigation accounts for more than half of the aquifer's discharge. Conservation districts are promoting more-efficient irrigation techniques, and market-based, voluntary transfers of unused agricultural water rights to municipal uses are more common. H2Oaks is Increased salinity may be associated with evaporative concentration of groundwater in saline playa lakes in the southern portion of the aquifer, up flow of more saline groundwater from the underlying Dockum Aquifer and other sources./p>.
