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 November and December 2022, following groundwater monitoring well development and groundwater-quality sampling, slug tests were completed on each of the groundwater monitoring wells installed in 2022 to (1) determine if the wells were in good hydraulic connection with the aquifer and (2) estimate the hydraulic conductivity of the aquifer at each well. This dataset includes the pressure transducer data from the slug tests and the hydraulic conductivity values estimated by using the Bouwer-Rice method of analysis.", "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.64935ec2d34ef77fcb013921.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_64935ec2d34ef77fcb013921", "keyword": ["Bristow", "Creek County", "Oklahoma", "Superfund", "USGS:64935ec2d34ef77fcb013921", "Wilcox Oil Company", "aquifer characterization", "benzene", "conceptual modeling", "field experiments", "geoscientificInformation", "geospatial analysis", "geospatial datasets", "groundwater flow", "groundwater level", "hydraulic conductivity", "hydraulic properties", "hydrogeologic framework", "hydrogeology", "hydrology", "industrial pollution", "permeability", "petroleum", "scientific interpretation", "slug test", "unconsolidated deposits"], "modified": "2025-06-26T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-96.386954, 35.839404, -96.382605, 35.843136", "theme": ["geospatial"], "title": "Aquifer Hydraulic Properties Data"}
