UMTRA Project Water Sampling and Analysis Plan, Riverton, Wyoming (open access)

UMTRA Project Water Sampling and Analysis Plan, Riverton, Wyoming

Surface remediation was completed at the former uranium mill site in Riverton, Wyoming, in 1990. Residual radioactive materials (contaminated soil and debris) were removed and disposed of at Union Carbide Corporation`s (Umetco) nearby Gas Hills Title 2 facility. Ground water in the surficial and semiconfined aquifers (known collectively as the `uppermost aquifer`) below the former mill and tailings site has been contaminated. No contamination has been detected in the deeper, confined sandstone aquifer. The contaminant plume extends off site to the south and east. The plume is constrained by surface wetlands and small streams to the east and west of the site and by the Little Wind River to the south. Fifteen monitor wells installed in 1993 were sampled to better define the contaminant plume and to provide additional water quality data for the baseline risk assessment. Samples also were collected from domestic wells in response to a request by the Wyoming Department of Environmental Quality in January 1994. No contamination attributable to the former uranium milling operations have ever been detected in any of the domestic wells used for potable supplies.

Surface remedial action is complete at the Spook Uranium Mill Tailings Remedial Action Project site in Wyoming. Based on an evaluation of site characterization data, the US Nuclear Regulatory Commission, US Department of Energy, and state of Wyoming have concurred in the determination that a program to monitor ground water is not required because ground water in the uppermost aquifer is Class 3 (limited use) (40 CFR 192.21(g)(1993)).

Lithologic Studies of Fine-Grained Upper Cretaceous Sedimentary Rocks of the Black Hills Region (open access)

Lithologic Studies of Fine-Grained Upper Cretaceous Sedimentary Rocks of the Black Hills Region

More than nine-tenths of the Upper Cretaceous rocks in northeastern Wyoming are fine-grained shales, mudstones, and calcareous marls. A comparative study of the mineralogy, chemical and mechanical composition, density and porosity, fissility, and lamination of samples of these rocks discloses several relations that throw light on the geologic history and structural deformation of the region, and perhaps on its oil and gas possibilities.

Airborne Radiometric Survey of the East Flank of the Big Horn Mountains, Wyoming and Montana (open access)

Airborne Radiometric Survey of the East Flank of the Big Horn Mountains, Wyoming and Montana

Abstract: An airborne radiometric survey of parts of the east flank of the Big Horn Mountains was begun on June 23, and completed on August 27, 1952. An area of approximately 250 square miles was covered, and only two anomalies were found in the entire area. Flight lines were arranged in accordance with the geology of the area, particular attention being given to formations the stratigraphic equivalents of which are known to be uranium bearing in other areas. Two additional zones of radioactivity were found by ground investigation, but assays from both the ground and the airborne discoveries showed no economic uranium deposits.

Lost Creek (Wamsutter) Schroeckingerite Deposit, Sweetwater County, Wyoming

Summary: The Lost Creek schroeckingerite deposit in Sweetwater County, Wyo., has attracted attention in the past both as an occurrence of comparatively rare minerals and more recently as a possible source of uranium ore. During the summer of 1948 a newly-formed company by the name of Uranium, Inc., explored part of the deposit by bulldozer trenching and drilling. under the technical direction of the Minerals Engineering Company of Grand Junction, Colo. Examination of the significant exposures of the schroeckingerite deposit indicated that the uraniferous beds are discontinuous and that their areal distribution is erratic. The overburden has an average thickness of 2.5 feet.

Video Processing of Remote Sensor Data Applied to Uranium Exploration in Wyoming: Final Report (open access)

Video Processing of Remote Sensor Data Applied to Uranium Exploration in Wyoming: Final Report

From introduction: This study is a comprehensive investigation of altered sandstone associated with uranium deposits near Pumpkin Buttes in the Powder River Basin of Wyoming, and the detection of such alteration using remote sensing technology. The purpose of this study is two-fold: 1) to develop video image processing techniques that will preferentially enhance areas of alteration associated with uranium deposits and enable mapping of these areas, and 2) to investigate the spectral, geochemical, and mineralogical characteristics of altered areas which make them detectable on remote sensor data. Once these video processing techniques have been defined, they may be applied as exploration tools to new areas with similar surface and geological environments. In this way, remote sensing can serve as a valuable tool for uranium exploration.

[Wyoming Uranium Evaluation] Volume 1: A Summary of the Geology and Uranium Potential of Precambrian Conglomerates in Southeastern Wyoming

From deposit: Since 1975 a cooperative effort between the United States Department of Energy, United States Geological Survey, Geological Survey of Wyoming, the Geology Department, University of Wyoming, and various industry groups has resulted in the discovery of a series of uraniumthorium-and gold-bearing conglomerates in Late Archean and Early Proterozoic metasedimentary rocks of southern Wyoming. The mineral deposits were found by applying the time and strata bound model for the origin of uranium-bearing quartz-pebble conglomerates to favorable rock types within a geologic terrane known from prior regional mapping.

From introduction: This volume is presented as a companion to Volume I: The Geology and Uranium Potential of Precambrian Conglomerates in the Medicine Bow Mountains and Sierra Madre of southeastern Wyoming; and to Volume 3: Uranium Assessment for Precambrian Pebble Conglomerates in Southeastern Wyoming. In Volume 1, we summarized the geologic setting and geologic and geochemical characteristics of uranium-bearing conglomerates in Precambrian metasedimentary rocks of southeastern Wyoming. Volume 3 is a geostatistical resource estimate of U and Th in quartz-pebble conglomerates. This volume contains supporting geochemical data, lithologic logs from 48 drill holes in Precambrian rocks of the Medicine Bow Mountains and Sierra Madre, and drill site geologic maps and cross-sections from most of the holes.

[Wyoming Uranium Evaluation] Volume 3: Uranium Assessment for the Precambrian Pebble Conglomerates in Southeastern Wyoming

From introduction: The Geology Department of the University of Wyoming was asked to make a geostatistical assessment of the uranium endowment of these deposits as a part of the World Class core drilling operations of the Bendix Field Engineering Corporation. This study was to include (a) the development of optimum geostatistical methodology for assessing uranium endowment in areas of close drill control (1 mile or less centers) as well as in areas of distant drill control (5 mile centers or more), (.b) the implementation of this methodology in assessing the uranium resources of the pebble conglomerates in southeastern Wyoming, and (c) the determination of the overall geostatistical uncertainty of the resource estimates. In addition, methods were to be studied for projecting the assessments into new areas, including prediction of estimate uncertainty.
