    <descript>
      <abstract>The Wilcox Oil Company Superfund site (hereinafter referred to as “the site”) was formerly an oil refinery in northeast of Bristow in Creek County, Oklahoma. 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 “contaminants”) were measured in a local shallow perched groundwater system within the alluvium (hereinafter referred to as the “alluvial aquifer”) 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.

Twenty new groundwater monitoring wells were installed at the site by the U.S. Geological Survey in October 2022, to collect groundwater-level altitude measurements and groundwater-quality samples within the alluvial aquifer, thus supplementing the existing data from older groundwater monitoring wells and piezometers at the site. An electrical conductivity log and a soil core were collected at each location where a groundwater monitoring well was installed to better understand and correlate observations in the subsurface and more accurately determine contamination zones.</abstract>
      <purpose>Electrical conductivity log and soil-core data were used to evaluate selected attributes of the hydrogeologic framework of the shallow groundwater system including the geospatial extents of hydrogeologic units, bed orientations, hydrogeologic unit thicknesses, and their outcrop and subcrop locations in the study area.</purpose>

        <procdesc>Electrical conductivity (EC) is the relative ability of earth material to transmit a current. As discussed in Teeple (2017, p. 6), “The electrical properties of soil and rock are determined by water content, porosity, clay content, and conductivity (reciprocal of electrical resistivity) of the pore water (Lucius and others, 2007).***Electrical changes detected within the subsurface also reflect changes that occur within the hydrogeology.” Prior to installing a groundwater monitoring well, a borehole EC log was collected by using direct-push technology (DPT) whereby a machine is used to push sampling tools, instruments, and sensors into the subsurface without the need for a rotary drill to remove the soil (Kejr, Inc., 2023a). Typically, DPT machines rely on static weight and percussive energy to help advance the tool (Kejr, Inc., 2023a). A 1.5-inch diameter Geoprobe EC sensor (Kejr, Inc., 2023b) is at the tip of the DPT drive-head device and uses an array of four electrodes (two transmitter [Tx] electrodes and two receiver [Rx] electrodes) to measure EC of the soil in millisiemens per meter as it is pushed into the subsurface (Teeple, 2017). A known current was transmitted into the subsurface through the Tx electrodes, and the resulting electrical potential was measured as a voltage change between the two Rx electrodes (Teeple, 2017). Using the known current, the measured voltage values, and the geometric factor dependent on the array, a conductivity value was calculated by using Ohm’s law (Teeple, 2017). For this study, EC values were typically lower in coarse-grained sediments such as sand or gravel than in fine-grained sediments such as clay and silt or sediment contaminated with previously refined or stored products at the site. EC logs were terminated at a depth of 20 feet (ft) or at the depth of refusal as a result of encountering either well-lithified sandstones or hard, dense clay or mudstone units (EA Engineering, Science, and Technology, Inc., PBC, 2020). Depth of refusal was defined as the point at which the hammer or other tool used to drill the borehole failed to advance the borehole as additional blows were applied by the tool to the rock being removed (Minnesota Pollution Control Agency, 2023). The encountered sandstones or mudstone units are generally related to the sandstones and mudstones of the Barnsdall Formation (Stanley, 2017), and therefore, the depth of refusal is interpreted as the depth to the top of the Barnsdall Formation. The total depth of 20 ft was selected because the focus of this study was the shallow perched groundwater system within the alluvium, and the depth to groundwater was typically no more than 15 ft; the intent was to have at least a 5-ft screen interval below the top of the groundwater table. Data were not collected or were unusable because of issues with the EC probe at wells USGS-12, USGS-19, and USGS-23.</procdesc>

        <procdesc>Directly adjacent to the electrical conductivity borehole, a 1.5-inch diameter soil core was collected to the same depth, if possible. The variability of consolidated sediments resulted in varying depths of penetration even if the tool was moved just a few feet; depths typically varied between the EC borehole and adjacent soil core by about 0.5 to 1 ft, but greater differences sometimes occurred. The soil core was segmented into lithologic units wherein each segment that was discernable from the unit above and below was individually described for color, grain size, and sorting by using field charts based on methods outlined in Wentworth (1922), Shepard (1954), Compton (1962), Schlee (1973), Folk (1980), Munsell Color Co., Inc. (1992), and Poppe and others (2005). The soil-core descriptions were described on site and then later digitized to a machine-readable text file.

A photoionization detector (PID) was used to monitor the presence of volatile organic compounds (VOCs) during groundwater monitoring well installation. VOC off-gassing was monitored throughout the drilling and soil-core description processes. The VOC concentration values detected were used to determine the severity of contamination at each location where a groundwater monitoring well was installed at the site. The PID was used only to detect general VOCs, so the presence of specific VOCs was not determined during groundwater monitoring well installation. The VOC concentration and saturation was noted in the soil-core description. Once a groundwater monitoring well was installed, the soil core was disposed of properly, as it contained contaminants from the subsurface alluvium.</procdesc>

        <procdesc>After collecting the soil core, the Geoprobe direct-push technology drilling system was used to install the groundwater monitoring well; each groundwater monitoring well was installed by directly pushing a 3.25-inch (in.) outer diameter rod with an expendable point down the same hole where the soil core was collected. After reaching the desired depth, the prepacked screens (Kejr, Inc., 2023c) and 1.5-in. polyvinyl chloride (PVC) risers were placed inside the 3.25-in. rod, with the screens placed at an optimal depth for groundwater sampling. The prepacked screens were made of slotted PVC wrapped in sand and stainless-steel mesh (Kejr, Inc., 2023c). The outer diameter of the screens is 2.5 in. with an inner diameter of 1.5 in. (Kejr, Inc. 2023c). The prepacked screens were secured in the borehole with 20/40 mesh sand (more than 90 percent of the sand grains by weight are between 0.85 and 0.425 millimeter) (Zheng and Tannant, 2016). Annular sealing was completed by using sodium bentonite pellets (0.25- to 0.75-in. size) starting from about 0.5 feet (ft) above the top of the screen to about 2 ft below land surface. The surface seal was completed with concrete from land surface to a depth of about 2 ft below land surface. A 3 by 3-ft square concrete pad was installed flush with land surface at each groundwater monitoring well having a thickness of about 4 in. Well construction information was noted in the field and then later digitized to a machine-readable text file. Each groundwater monitoring well was geospatially referenced with coordinates collected from a real-time kinematic (RTK) Global Positioning System (GPS) receiver.</procdesc>

The binary (DAT and T01) files are proprietary files generated by the Trimble GPS data collection hardware that need the ConvertToRinex software to convert them into ACSII files. The resulting converted ASCII files (22G, 22N, and 22O) are in Receiver Independent Exchange (RINEX) version 2.11 format. More information on the RINEX format is found in the RINEX211.txt file. The first 8 digits of the filename represents a naming convention given to the file by the RTK GPS receiver followed by an underscore and the identifier for the well where the data were collected where hyphens are represented as underscores.</enttypd>
