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.
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...
The Ogallala aquifer is contained in the Tertiary-age Ogallala Formation in the Texas Panhandle and is the primary water-bearing hydrogeologic unit of the High Plains aquifer system. The Ogallala aquifer is the primary source of water used for agricultural and municipal purposes in the Texas Panhandle. The Dockum aquifer is contained in the formations that compose the Triassic-age Dockum Group and serves as an additional source of water in the Texas Panhandle. Depth to groundwater measurements and water-quality samples were collected from 32 monitoring wells in the North Plains Groundwater Conservation District management area within the northern part of the Texas Panhandle as part of two synoptic sampling efforts,...
This part of the data release contains historical streamflow data compiled from the literature and evaporation loss estimates used in the streamflow gain loss equation. These digital data accompany Houston, N.A., Thomas, J.V., Ging, P.B., Teeple, A.P., Pedraza, D.E., and Wallace, D.S., 2019, Pecos River Basin Salinity Assessment, Santa Rosa Lake, New Mexico to the Confluence of the Pecos River and the Rio Grande, Texas,2015: U.S. Geological Survey Scientific Investigations Report 2019-5071, https://doi.org/10.3133/sir20195071.

This Data Release contains various types of hydrologic and geologic data from the Pecos River Basin during1900–2015, including water-quality data compiled and synthesized from various sources (including data from water-quality samples collected by the USGS in 2015 from 26 sites), streamflow gain-loss data collected by the USGS in 2015 and historical streamflow gain-loss data compiled from the literature, the horizontal extent of and depth to the base of the 16 geologic and hydrogeologic units that underlie the study area, and geospatial data collected by the USGS. The data were used to complete a detailed salinity assessment of the Pecos River from Santa Rosa Lake, New Mexico to the Confluence of the Pecos River...

This part of the Data Release contains the water-quality data compiled and synthesized from various sources(including data from water-quality samples collected by the USGS in 2015 from 26 sites). This collection includes three main tables that contain (1) the list of site locations that water-quality data were collected, and information about those sites, such as the spatial coordinates of a well (Site_information); (2)the list of samples that were collected, and information about those samples, such as the date the sample was collected (Sample_information); and (3) the results of the measured constituent, and information about the result such as amount of concentration measured in a constituent(Water_quality_results)....

Patrick Bayou, a section of the Houston Ship Channel near Deer Park, Texas, has accumulated permitted industrial wastewater discharges, municipal wastewater treatment plant effluent, and stormwater runoff from adjacent industrial facilities and nearby urban and residential areas. These discharges are suspected to be the primary sources of the sediment contamination in the Patrick Bayou section of the Houston Ship Channel near Deer Park, Texas. The U.S. Environmental Protection Agency (EPA) placed Patrick Bayou on the Superfund program’s National Priorities List because of sediment contamination detected in the wetlands bordering Patrick Bayou, posing a threat to downstream fisheries. The U.S. Geological Survey (USGS),...
This part of the data release contains geospatial data collected and compiled during the Pecos River Basin salinity assessment of the Pecos River Basin from Santa Rosa Lake in New Mexico to the confluence of the Pecos River and the Rio Grande in Texas. Raster representations of horizontal extent, and depth below land surface to the base of sixteen Quaternary through Permian aged geologic units that underlie the Pecos River Basin are provided in image format. These units include: the San Andres Limestone; the Artesia Group which includes the Grayburg, Queen, Seven Rivers, Yates, and Tansill Formations; Capitan Limestone; Castile, Salado, and Rustler Formations; the Dewey Lake Redbeds; the Dockum Group (divided into...

Groundwater-quality data and geophysical information for relatively deep wells (wells generally more than 300 feet deep) containing saline water (dissolved-solids concentrations greater than 2,000 milligrams per liter) are limited throughout the state of Texas. Information derived from geophysical well logs can be used to estimate groundwater salinity. Geophysical logs were collected in 2021 from 10 of the 12 wells completed in selected aquifers (Trinity, Edwards-Trinity (Plateau), Carrizo-Wilcox, Sparta, and Yegua-Jackson) in Texas.

This part of the data release contains the geospatial data collected by the USGS during the Pecos River salinity assessment. The data includes a feature class of the study area boundary and the Pecos River Basin boundary, the picks that were used to develop the depth to the base of the 16 geologic units, a feature class of springs, seeps and sinkholes compiled in the study area, a feature class of the USGS streamflow-gaging stations locations in the study area, a feature class of the locations of the saltwater disposal wells in the study area, and a feature class of areas of interest with respect to salinity. These digital data accompany Houston, N.A., Thomas, J.V., Ging, P.B., Teeple, A.P., Pedraza, D.E., and...

In late August and early September 2017, Hurricane Harvey made landfall on the southeastern coastline of Texas and produced a record amount of rainfall, leading to widespread flooding. From August 25 through September 1, 2017, some areas in southeastern Texas received more than 60 inches of rain with large areas receiving at least 40 inches of rain. Hurricane Harvey was the largest rainfall event in United States history in terms of spatial extent and rainfall totals since rainfall records began in the 1880s (Watson and others, 2018). The five most heavily flooded river basins in Texas during this storm included the Brazos River, where the U.S. Geological Survey (USGS) collected water-quality samples at the Brazos...

The availability of groundwater-quality data along with geophysical information 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 samples and geophysical logs were collected from a total of 12 wells completed in selected aquifers (Trinity, Edwards-Trinity (Plateau), Carrizo-Wilcox, Sparta, and Yegua-Jackson) in Texas.
