Historical refinery operations contaminated the soil, surface water, streambed sediments, alluvium, and groundwater with refined and stored products at the site. The Wilcox and Lorraine process areas are where the highest concentrations of volatile organic compounds, semivolatile organic compounds, polycyclic aromatic hydrocarbons, and trace elements (including metals) (collectively hereinafter referred to as \u201ccontaminants\u201d) were measured in a local shallow perched groundwater system within the alluvium (hereinafter referred to as the \u201calluvial aquifer\u201d) at the site during previous site assessments. In order to understand the potential migration of contaminants through the soil and groundwater in these areas, the U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency, investigated aquifer characteristics of the alluvial aquifer in the Wilcox and Lorraine process areas of the site to (1) document hydraulic conductivity and other aquifer characteristics of the alluvial aquifer that govern contaminant fate and transport, (2) describe the geospatial extent and concentration of the contaminants in the alluvial aquifer in the Wilcox and Lorraine process areas, and (3) describe the geochemical controls pertaining to oxidation and reduction governing the fate and transport and the degradation potential of contaminants in the groundwater. This data release documents the data that were collected and briefly describes how they were used to characterize the hydrogeologic framework, groundwater-flow system, geochemistry, and aquifer hydraulic properties of the shallow groundwater system. Refer to the companion larger work citation (Teeple and others, 2025) for the complete description and data analyses.\nIn January and August 2022, surface geophysical resistivity data were collected to characterize the sediments and their extents in the shallow groundwater system. Two methods were utilized: frequency domain electromagnetic (FDEM) and electrical resistivity tomography (ERT). Twenty new groundwater monitoring wells were installed at the Wilcox Oil Company Superfund site in October 2022, to enable the collection of additional data at locations of interest to supplement data collected from older groundwater monitoring wells and piezometers. An electrical conductivity log and a core sample were collected at each groundwater monitoring well installation location to better understand and correlate observations in the subsurface and more accurately determine contamination zones. This dataset includes the combined resistivity values of the surface geophysical data and the electrical conductivity logs and grid results.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9FR2ZF6", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.675223f3d34e5c4500cf478e.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_675223f3d34e5c4500cf478e", "keyword": ["Bristow", "Creek County", "Oklahoma", "Superfund", "USGS:675223f3d34e5c4500cf478e", "Wilcox Oil Company", "aquifer characterization", "benzene", "conceptual modeling", "data integration", "electrical resistivity imaging", "electrical resistivity logging", "electromagnetic surveying", "frequency domain electromagnetic", "geologic contacts", "geophysics", "geoscientificInformation", "geospatial analysis", "geospatial datasets", "hydrogeologic framework", "hydrogeology", "industrial pollution", "kriging", "lithostratigraphy", "petroleum", "scientific interpretation", "stratigraphic thickness", "unconsolidated deposits", "visualization methods"], "modified": "2026-03-20T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-96.388300, 35.838600, -96.380000, 35.845200", "theme": ["geospatial"], "title": "Hydrogeologic Framework Data: Combined Resistivity and Sand Dominant Group Data"}
