This dataset documents the depth to groundwater measured in wells screened in the Chicot aquifer, Evangeline aquifer, Jasper aquifer, Burkeville confining unit, Catahoula confining system, or a combination of multiple hydrogeologic units in the greater Houston area, Texas for 2021. 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 Groundwater Conservation District. This dataset was created to provide resource managers, public officials, researchers, and the general public with ready access to information regarding depths to groundwater in the region. All of the data in this dataset were collected from November 2020 through March 2021 and are stored in the National Water Information System (NWIS), a publicly available, searchable, online database of water information (http://doi.org/10.5066/F7P55KJN). These digital data accompany a U.S. Geological Survey Scientific Investigation Report by Braun and Ramage (2021).

This dataset contains the source information for pumping rates for municipal and industrial (MnI) wells in Texas within the Rio Grande Transboundary Integrated Hydrologic Model (RGTIHM). In RGTIHM, these wells are considered the Other Texas (OTX) group.

The Texas Water Development Board (TWDB) Groundwater Database (GWDB) contains information on selected water wells, springs, oil/gas tests (that were originally intended to be or were converted to water wells), water levels, and water quality to gain representative information about aquifers in Texas to support water planning from a local to a more regional perspective. This is a scientific database, not a registry of every well drilled in the state.

The High Plains aquifer extends from approximately 32 to 44 degrees north latitude and from 96 degrees 30 minutes to 106 degrees west longitude. The aquifer underlies about 175,000 square miles in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. This digital data set contains water-level measurements from wells screened in the High Plains aquifer and measured in both predevelopment (about 1950) and for 2017. There were 2,928 wells measured in both predevelopment (about 1950) and 2017 as well as 63 wells located in New Mexico, which were measured in predevelopment and at least once between 2013 and 2016. These water-level measurements were used to map water-level changes, predevelopment (about 1950) to 2017. The map was reviewed for consistency with the relevant data at a scale of 1:1,000,000.

These data contain basic information describing well logs and compiled by the Texas Bureau of Economic Geology, published as a downloadable file, ESRI Service, and as a Web Feature service for the National Geothermal Data System. The downloadable documents contain 9 worksheets, including information about the template, notes related to revisions of the template, resource provider information, the data, a field list (data mapping view) and a worksheet with vocabularies for use in populating the spreadsheet (data valid terms). Data from 2,491 total well logs are included. Fields in the data table include Well Name, API Number, Ended Drilling Date, Well Type, Bottom Logged Interval,and Log Notes.

This dataset provides simple features that report basic information describing a simple or complex borehole. Published by the Arizona Geological Survey as a web feature service, a web map service, and as an ESRI service for the National Geothermal Data System. Wells with multiple well bores may have separate records (rows) for each well bore, each with a distinct HeaderURI (record identifier); in this case, the ParentWellURI should provide the HeaderURI representing the well. If multiple data items are associated with a single well header, the multiple values are concatenated in a single text field using '|' as a delimiter. Borehole type is factored into 4 facets-- commodity of interest, well function, well status, and production result.

The Transboundary Aquifer Assessment Act was established to systematically assess priority aquifers along the U.S.-Mexico international boundary. The priority aquifers that were specified include the Hueco-Mesilla Bolsons aquifer in Texas and New Mexico and its counterpart in Mexico, the Conejos-Medanos Aquifer system, and the Santa Cruz and San Pedro aquifers in Arizona (Texas Water Development Board, 2019). The Transboundary Aquifer Assessment Program (TAAP) was started in 2009 and is a collaborative effort between the U.S. Geological Survey, Arizona Water Resources Research Center, New Mexico Water Resources Research Institute, and the Texas Water Resources Institute (U.S. Geological Survey, 2018) to better understand these aquifers. More information about TAAP can be found at the TAAP project website: https://webapps.usgs.gov/taap/. This data release contains data from water-quality analyses of groundwater samples collected from production wells within the Hueco Bolson which is part of the Hueco-Mesilla Bolsons aquifer system. Sampling locations were determined in coordination with El Paso Water and the U.S. Army Air Defense Artillery Center to meet TAAP goals of understanding groundwater-quality data and providing useful information to decision makers. Groundwater samples were collected from 20 production wells operated by El Paso Water and Fort Bliss Water Services during August 29–September 23, 2016. These samples were analyzed for major ions, trace elements, nutrients, pesticides, carbon isotopes, strontium isotopes, hydrogen isotopes, and oxygen isotopes. Three additional Fort Bliss Water Services wells were sampled between May 31 and June 1, 2017. These samples were analyzed for major ions, trace elements, dissolved gasses, carbon isotopes, strontium isotopes, hydrogen isotopes, oxygen isotopes, boron isotopes, and uranium isotopes.

Water Data for Texas is a product of the Texas Water Development Board (TWDB) Water Science Conservation Division and is made possible by the support of management and staff at TWDB. This project is part of our ongoing efforts to synthesize and communicate water-related data to scientists, policy makers and the public. As a convenience to the public, this website also retrieves and displays well data collected by the U.S. Geological Survey (USGS) and the Edwards Aquifer Authority (EAA). All data displayed for these wells are maintained by USGS and EAA respectively.

This project updates the geothermal resources beneath our oil and gas fields, as part of the research for the Texas GEO project. This report "Analysis of Geothermal Resources in Three Texas Counties" (October 2020) improves on previous mapping of the Texas resources for the counties of Crockett (West Texas), Jackson (central Gulf Coast) and Webb (South Texas). Through additional bottom-hole temperatures (BHT), the number of well sites increased from 532 to 5,410 in total for these counties. The improved methodology to calculate formation temperatures from 3.5 km (11,500 ft) to 10 km (32,800 ft) includes thermal conductivity values more closely related to the actual county geological formations, incorporated radiogenic heat production of formations, and the related mapped depth to basement. The results show deep temperatures as hotter than previously calculated, with temperatures of 150 degrees Celcius possible for Webb County between depths of 2.6 - 5.1 km, Jackson County between depths 3.0 - 5.4 km, and Crockett County between depths of 2.7 - 8.0 km.

In cooperation with the San Antonio Water System, continuous and discrete water-quality data were collected from groundwater wells completed in the Edwards aquifer, Texas, 2014-2015. Discrete measurements of nitrate were made by using a nitrate sensor. Precipitation data from two sites in the National Oceanic and Atmospheric Administration Global Historical Climatology Network are included in the dataset. The continuous monitoring data were collected using water quality sensors and include hourly measurements of nitrate, specific conductance, and water level in two wells. Discrete measurements of nitrate, specific conductance, and vertical flow rate were collected from one well site at different depths throughout the well bore.

The availability of groundwater-quality data for relatively deep wells (wells generally more than 300 feet deep) containing saline water (dissolved-solids concentrations greater than 2,000 milligrams per liter) is limited throughout the state of Texas. Water-quality samples are important for calibrating estimates of groundwater salinity derived from geophysical well logs. Water-quality data collected in 2021 from four wells completed in selected aquifers (Trinity, Carrizo-Wilcox, and Yegua-Jackson) in Texas are included in this data release.

This data release contains compiled historical groundwater-withdrawal data for the Coastal Lowlands aquifer system in Texas, Louisiana, Mississippi, Alabama, and Florida from 1925 to 2018. Most groundwater-withdrawals were distributed to groundwater wells and separated into water-use categories of industrial, production well, power generation, mining, domestic, irrigation, livestock or commercial. Groundwater-withdrawal data were obtained, where available, from existing database resources hosted by various State and Federal agencies. For Texas, data were obtained from the Texas Water Development Board (TWDB) from both existing Groundwater-Availability Models (GAM), and from historical groundwater-withdrawal data. For Louisiana data were obtained from the U.S. Geological Survey Lower Mississippi-Gulf Water Science Center, Baton Rouge, Louisiana office. For Mississippi data were obtained from the Mississippi Department of Environmental Quality, and from the U.S. Geological Survey Lower Mississippi-Gulf Water Science Center, Jackson, Mississippi. For Alabama data were obtained from the Alabama Department of Economic and Community Affairs, Office of Water Resources, and from the U.S. Geological Survey Lower Mississippi-Gulf Water Science Center, Montgomery, Alabama office. For Florida data were obtained from the U.S. Geological Survey Caribbean-Florida Water Science Center, Lutz and Orlando Florida offices.
