Sediment samples and samples for water-toxicity testing were collected during 2014 from several streams in San Antonio, Texas known locally as the Westside creeks (Alazán, Apache, Martínez, and San Pedro Creeks) and from the San Antonio River. Samples were collected once during base-flow and again after periods of storm-water runoff (post-storm conditions) to determine baseline sediment- and water-quality conditions. Streambed-sediment samples were analyzed for selected constituents, including trace elements and organic contaminants such as pesticides, polychlorinated biphenyls (PCBs), brominated flame retardants, and polycyclic aromatic hydrocarbons (PAHs).

The U.S. Geological Survey (USGS) in cooperation with the Harris‐Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, and Lone Star Groundwater Conservation District has produced this dataset of groundwater‐level altitudes and groundwater‐level altitude changes in the Chicot, Evangeline, and Jasper aquifers in the Houston‐Galveston region, Texas. This dataset shows current‐year (2018) groundwater‐level altitudes for each aquifer, 5‐year (2013‐18) groundwater‐level changes for each aquifer, long‐term (1990‐2018 and 1977‐2018) groundwater‐level changes for the Chicot and Evangeline aquifers, and long‐term (2000‐2018) groundwater‐level change for the Jasper aquifer. The groundwater‐level measurements...
More than 11,500 well records, such as geophysical logs, drilling descriptions, and published hydrogeologic framework information, were evaluated to help characterize the framework of hydrogeologic units in and near Gaines, Terry, and Yoakum Counties, Texas. Additional geophysical data were collected to improve the spatial coverage across the study area and to reduce uncertainty with regard to hydrogeologic unit extents. The evaluation of existing data plus the collection of new geophysical data provided that basis for developoing a refined understanding of how the saturated thickness of the Ogallala and Edwards-Trinity aquifers vary throughout the study area.
The U.S. Geological Survey, in cooperation with the Harris‐Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, Brazoria County Groundwater Conservation District, and Lone Star Groundwater Conservation District, has produced this dataset of water-level changes and approximate water-level altitudes in the Chicot, Evangeline, and Jasper aquifers in the Houston-Galveston region, Texas.

Temporal patterns in glyphosate and atrazine concentrations were measured weekly by the U.S. Geological Survey (USGS) during the 2013 growing season in 100 small streams in the Midwestern United States. Concentrations also were measured every 2 days at a subset of 8 of the sites, all located in Missouri. Glyphosate was detected more frequently in urban streams than in agricultural streams, and at concentrations similar to those in streams with high agricultural land use in the watershed. In contrast, atrazine was detected more frequently and at higher concentrations in agricultural streams than in urban streams. This data release provides watershed characteristics and 2013 glyphosate and atrazine compound concentrations...

The transboundary Mesilla Basin/Conejos-Médanos aquifer system was identified as one of the priority transboundary aquifer systems for additional study by the United States and Mexico U.S.-Mexico Transboundary Aquifer Assessment Act of 2006 (United States-Mexico Transboundary Aquifer Act, Public Law 109-448). As one of the largest rechargeable groundwater systems by total available volume in the Rio Grande/Rio Bravo del Norte Basin region of the United States and Mexico, the Mesilla Basin/Conejos-Médanos aquifer system supplies water for irrigation as well as municipal use in El Paso, Texas; Las Cruces, New Mexico; and Ciudad Juárez, Chihuahua, Mexico (Alley, 2013). The U.S. Geological Survey in cooperation with...
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...
Please note: a more recent version of this dataset is available. Users are strongly advised to access the newer version of the dataset at https://doi.org/10.5066/P9YGUE2V. The U.S. Geological Survey, in cooperation with the Harris‐Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, and Lone Star Groundwater Conservation District, produced a dataset through 2017 of compaction values in the Chicot and Evangeline aquifers in the Houston‐Galveston region, Texas. This dataset contains compaction values of subsurface sediments (mostly in the fine-grained silt and clay layers because little compaction occurs in sand layers) in the Chicot and Evangeline aquifers that were recorded continuously...

This data release consists of three geophysical data sets measured in the lower Guadalupe River channel, south-central Texas, and one supplementary geophysical data set measured in a laboratory. The lower Guadalupe River is incised into the outcrop of the Carrizo-Wilcox aquifer in south-central Texas. The river and the aquifer are hydraulically connected across the outcrop, although the connectivity is obscured by alluvium and surface-water and groundwater exchange dynamics are currently poorly understood. The data sets were therefore produced to investigate surface-water and groundwater exchange dynamics between the lower Guadalupe River and the Carrizo-Wilcox aquifer, and consist of (1) a 14.86 kilometer (km)...

To help characterize the groundwater system at Homestake Mining Company Superfund Site near Milan, New Mexico, the U.S. Geological Survey collected borehole geophysical and groundwater-quality data in cooperation with the U.S. Environmental Protection Agency during July–October 2016. The following borehole geophysical data were collected from wells at or near the Homestake Mining Company Superfund Site: induction, fluid resistivity, natural gamma, spectral gamma, fluid temperature, caliper, casing collar locator, optical televiewer, and electromagnetic flow meter logging (ambient and stressed). The geophysical data were used to evaluate well construction, stratigraphy, distribution of potassium, uranium, and thorium,...
The Soil Water Assessment Tool (SWAT) model was used to simulate the hydrologic response of a watershed in south-central Texas within the Honey Creek State Natural Area for the time period 2001 to 2010; the simulation was focused on simulating the hydrologic outcomes of brush management. Specifically a SWAT2012 (Arnold et al., 2012) model of the watershed was built using the ArcSWAT tool (Winchell et al., 2007). Included are the necessary files and processing scripts for users to recreate the Monte Carlo and global sensitivity analysis results presented in the publication. Note the actual outputs from the analyses are not included herein because of storage size limitations. The results of the SWAT modeling are presented...
This dataset provides compiled and computed data from 1900 through 2017 associated with streamflow statistics used to perform regional analyses for the Brazos, Colorado, Big Cypress, Guadalupe, Neches, Sulphur, and Trinity River Basins. These seven river basins are mostly within Texas, but parts of some of the basins extend into New Mexico and Louisiana. Because changes in precipitation, temperature and groundwater levels can appreciably affect streamflow, understanding changes in streamflow requires taking these forcing variables into account. Long-term streamflow statistics for these seven river basins were derived by analyzing streamflow data and other observed climatological variables. Data include tables of...
The Edwards aquifer in south central Texas is one of the most permeable and productive aquifers in the United States and is the major source of public water supply for Bexar, Comal, Hays, Medina, and Uvalde Counties. The Edwards aquifer also supplies large quantities of water to agriculture, business, and industry in the region. The major artesian springs of the Edwards aquifer provide water for recreational activities, businesses, and downstream users, and provide habitat for several threatened or endangered species. The areas pertinent to the recharge process are the catchment area and the recharge zone. The catchment area consists of the parts of stream basins upstream from the recharge zone. Streams in the...
This data release consists of three different types of geoelectric data measured along three curvilinear profiles during two separate geophysical surveys completed on July 9, 2017 and January 9, 2018. The datasets include three self-potential (SP) profiles, two spatially-coincident electric contact-resistance (CR) profiles, and two spatially-coincident electric resistance tomography (ERT) tomograms. All profiles were oriented in a northeast-southwest alignment along 650 meters of a natural berm parallel to a surface-water reservoir to the west and Hamilton Creek to the east, in Burnet County, Texas. The profiles along the berm began at latitude and longitude coordinates (30.716319o N, -98.229917o W) and terminated...
