Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Volatile and semivolatile organic compound concentrations in paired porewater and surface-water samples and groundwater samples at the Garland Creosoting Superfund Site, Longview, Texas, 2023–24 Volatile and semivolatile organic compound concentrations in paired porewater and surface-water samples and groundwater samples at the Garland Creosoting Superfund Site, Longview, Texas, 2023–24
The Garland Creosoting Superfund Site in Longview, Texas is an abandoned wood treatment facility that used creosote to preserve wood products between 1960 and 1997. Previous remediation activities at the contaminated site included excavation of creosote-contaminated soil and the installation of an interceptor collector trench and groundwater treatment system to prevent the movement of...
MODFLOW-NWT model data used to simulate base flow and groundwater availability under different future climatic conditions for reach 1 of the Washita River alluvial aquifer and Foss Reservoir, western Oklahoma MODFLOW-NWT model data used to simulate base flow and groundwater availability under different future climatic conditions for reach 1 of the Washita River alluvial aquifer and Foss Reservoir, western Oklahoma
A previously calibrated MODFLOW-NWT groundwater-flow model (https://doi.org/10.3133/sir20205118) was used to determine the effects of climate variability under a range of future climatic conditions on groundwater resources in the reach 1 of the Washita River alluvial aquifer in western Oklahoma. The study area focuses on reach 1 of the Washita River alluvial aquifer; the entire Washita...
Rangeland Condition Monitoring Assessment and Projection (RCMAP) Independent Validation Data Rangeland Condition Monitoring Assessment and Projection (RCMAP) Independent Validation Data
Rangeland ecosystems provide critical wildlife habitat (e.g., greater sage grouse, pronghorn, black-footed ferret), forage for livestock, carbon sequestration, provision of water resources, and recreational opportunities. At the same time, rangelands are vulnerable to climate change, fire, and anthropogenic disturbances. The arid-semiarid climate in most rangelands fluctuates widely...
Geospatial Dataset for the Geologic Framework and Hydrostratigraphy of the Edwards and Trinity Aquifers Within Northern Medina County, Texas at 1:24,000 Geospatial Dataset for the Geologic Framework and Hydrostratigraphy of the Edwards and Trinity Aquifers Within Northern Medina County, Texas at 1:24,000
The karstic Edwards and Trinity aquifers are classified as major sources of water in south-central Texas by the Texas Water Development Board, and both are classified as major aquifers by the State of Texas. The Edwards and Trinity aquifers developed because of the original depositional history of the carbonate limestone and dolomite rocks that contain them, and the primary and secondary...
Self-potential tomography preconditioned by particle swarm optimization—Self-potential monitoring and streamflow data acquired March 26–September 14, 2023 at East Fork Poplar Creek near Oak Ridge Tennessee, with forward and inverse modeling computer scrip Self-potential tomography preconditioned by particle swarm optimization—Self-potential monitoring and streamflow data acquired March 26–September 14, 2023 at East Fork Poplar Creek near Oak Ridge Tennessee, with forward and inverse modeling computer scrip
This data release contains self-potential (SP) monitoring data measured on the flood plain of East Fork Poplar Creek (East Fork) in Oak Ridge, Tennessee and streamflow data measured at streamgage EFK5.4 about 310 meters upstream from the SP monitoring site. Additionally, forward and inverse numerical modeling scripts used to model the electrical-potential field on the East Fork flood...
82.4-kilometer profiles of waterborne self-potential and water-quality data measured August 28–September 1, 2023, in the Trinity River between the Elm Fork confluence and North Texas Municipal Water District Main Stem Pump Station in Scurry, Texas 82.4-kilometer profiles of waterborne self-potential and water-quality data measured August 28–September 1, 2023, in the Trinity River between the Elm Fork confluence and North Texas Municipal Water District Main Stem Pump Station in Scurry, Texas
This data release contains 82.4-kilometer (km) long spatial profiles of geophysical and water-quality properties data acquired along five semi-continuous segments of the Trinity River that were surveyed August 28 – September 1, 2023. The surveyed reaches start at the Elm Fork confluence in the Dallas, Texas metropolitan area and end at a pump station in Scurry, Texas. The geophysical...
