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.

Datasets include hydrogeologic cross section wells within the Red River alluvial aquifer surficial extent, Red River alluvial aquifer base contours and wells, isopach map showing combined thickness of the Red River alluvial aquifer sand and gravel units, wells used to construct the isopach map of the Red River alluvial aquifer, wells used to construct 25-foot contours showing altitude of the base of the Red River alluvial aquifer, cross-section wells within the Carrizo-Wilcox aquifer, thickness of the Carrizo-Wilcox aquifer contours and well points, contours showing the altitude of the base of freshwater of the Carrizo-Wilcox aquifer, outcrop extent of the Carrizo-Wilcox aquifer outcrop, and the approximate down-dip...

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.

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.

This dataset includes isopach contours showing altitude of freshwater of the Carrizo-Wilcox aquifer, control points used to construct the freshwater isopach contours, isopach contours showing altitude of top of the Carrizo-Wilcox aquifer, wells used to construct cross sections and isopach contours, hydrogeologic cross section H-H' through S-S' lines, isopach contours showing altitude of the base of the Carrizo-Wilcox aquifer, well points used to construct base isopach contours, isopach contours showing thickness of the Carrizo-Wilcox aquifer, and wells used to construct thickness isopach contours. Datasets are shown in figures of the larger body of work "Hydrogeologic framework of the Red River alluvial aquifer...

This dataset includes the surficial extent of the Red River alluvial aquifer, cross-section wells within the Red River alluvial surficial extent, Red River alluvial aquifer base contours and wells, isopach showing combined thickness of the Red River alluvial aquifer sand and gravel units, wells used to construct the isopach of the Red River alluvial aquifer, and well points that were used to construct 25-foot contours showing the altitude of the base of the Red River alluvial aquifer. Datasets are shown in figures of the larger body of work "Hydrogeologic framework of the Red River alluvial aquifer and Carrizo-Wilcox aquifer, in northwestern Louisiana" (Hays and others, 2021).
