However, water quality diminishes to the south, where large areas contain total dissolved solids in excess of 1,000 milligrams per liter. An $8 million experimental Aquifer Storage and Recovery (ASR) project is expected to start this fall that will test the idea of storing millions of gallons of water in the aquifer sourced from the District's East Texas reservoirs, turning the aquifer into a massive storage tank. Natural salt pollution in the upper reaches of the Red and Brazos river basins precludes the full utilization of these water resources.

Semiconsolidated aquifers consist of semiconsolidated sand interbedded with silt, clay, and minor carbonate rocks Sandstone aquifers are more widespread than those in all other kinds of consolidated rocks. Please note that the maps do not show the entire extent of an aquifer, only itssubcropor outcrop area. In general, groundwater is fresh but very hard in the outcrop of the aquifer. Texas has numerous aquifers capable of producing groundwater for households, municipalities, industry, farms, and ranches.

An official website of the United States government. 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). These aquifers are located in El Paso and Hudspeth counties in far West Texas and occur in Tertiary and Quaternary basin-fill deposits that extend northward into New Mexico and westward into Mexico. The Aggregate Water-Use Data System (AWUDS) is the database management system used to enter, store, and analyze state aggregate water-use data.

Surficial deposits which are not of glacial origin may be coded as Alluvial aquifers. The Texas Water Development Board (TWDB) recognizes 9 major aquifers aquifers that produce large amounts of water over large areas (see major aquifers map) and 22 minor aquifers aquifers that produce minor amounts of water over large areas or large amounts of water over small areas (see minor aquifers map). Water level increases were found in the northern portion of the study area, near the Yoakum and Terry County boundary and in northeastern Gaines County. Sulfate and chloride concentrations also tend to increase with depth.

Click any position on the map to reveal attributes for a specific location. Historical large-scale groundwater withdrawals, especially for the municipal uses of El Paso and Juarez, have caused major water-level declines and significantly changed the direction of flow, causing a deterioration of the chemical quality of the groundwater in the aquifer, according to El Paso Water Utilities and the USGS. Irrigation was the principal use in Medina and Uvalde counties. Whether you are a teacher or home-school parent, you will find our Teacher's Guide to be an invaluable tool for teaching all things Texas to your students. The San Antonio River Authority also has a number of flood-control structures that effectively recharge the aquifer.

The quality of groundwater used for public supply was assessed in 25 principal aquifers (PAs) that account for 84% of groundwater pumped for public supply in the U.S. (89.6 million people on a proportional basis). However, because these aquifers extend over large areas, large volumes of water can be withdrawn. The information was collected by the U.S. Geological Survey and other agencies during the course of many years of study. This area corresponds to the principal recharge zone for the aquifers. The aquifer is comprised of the Twin Mountains, Glen Rose, Paluxy, Hosston, and Hensell formations.
