This report represents an evaluation of depleted uranium (DU) introduced into the environment at the Aberdeen Proving Grounds (APG), Maryland and Yuma Proving Grounds (YPG) Arizona. This was a cooperative project between the Environmental Sciences and Statistical Analyses Groups at LANL and with the Department of Fishery and Wildlife Biology at Colorado State University. The project represents a unique approach to assessing the environmental impact of DU in two dissimilar ecosystems. Ecological exposure models were created for each ecosystem and sensitivity/uncertainty analyses were conducted to identify exposure pathways which were most influential in the fate and transport of DU in the environment. Research included field sampling, field exposure experiment, and laboratory experiments. The first section addresses DU at the APG site. Chapter topics include bioenergetics-based food web model; field exposure experiments; bioconcentration by phytoplankton and the toxicity of U to zooplankton; physical processes governing the desorption of uranium from sediment to water; transfer of uranium from sediment to benthic invertebrates; spead of adsorpion by benthic invertebrates; uptake of uranium by fish. The final section of the report addresses DU at the YPG site. Chapters include the following information: Du transport processes and pathway model; field studies of performance of exposure …

Interview with William Creacy concerning his experiences before, during and after his employment in the Civilian Conservation Corps during the Great Depression. Creacy worked at camps in Elephant Butte, Arizona (Company 855); Tucson, Arizona; Grand Lake, Colorado; and Yuma, Arizona.

Footage of an AH-1W SuperCobra weapons test. The film covers test flights 266A and 266B and features tests of the TOW missile launcher and the AIM-9 Sidewinder missile. No sound.

Purpose and scope: The purpose of this study was to develop a method for estimating the amount of subsurface return flow to the Colorado River in the Yuma area. This report presents a method that permits an approximate accounting of ground-water return flow from each side of the Colorado River in Yuma reach. The method presented in this report was developed specifically for application in the Yuma area. The validity of the assumptions inherent in the method was evaluated on the basis of the local hydrologic system. The applicability of the method to other hydrologic systems is not addressed in this report.

Purpose and scope: The purpose of this study was to develop a method for estimating the amount of subsurface return flow to the Colorado River in the Yuma area. This report presents a method that will permit an accounting of ground-water return flows from each side of the Colorado River in the Yuma reach. The estimates of return flow can be used by water-management agencies in determining return-flow credits for the States of Arizona and California.

From abstract: This drilling project in northwestern Arizona consisted of 18 holes drilled to depths ranging from 1,341 to 5,491 feet (409 to 1,673 meters). The holes were sited to determine the lateral extent of the uranium-bearing, paludal/lacustrine strata of the Anderson Mine in Date Creek basin and to obtain additional data to improve the resource estimates for the Date Creek and Big Sandy basins.

Supplementary data containing geophysical logs to accompany a geologic report on drilling in the Western Prescott and Williams Quadrangles.

One hot spring and 33 wells drilled in the county discharge water at temperatures sufficient for direct-use geothermal applications such as process heat and space heating and cooling. Currently, one industry within the county has been identified which may be able to use geothermal energy for its process heat requirements. Also, a computer simulation model was used to predict geothermal energy on line as a function of time under both private and city-owned utility development of the resource.

From summary: The objective of the project was to obtain subsurface data that would permit a more accurate estimate to be made of the uranium potential in the Tertiary basins within the project area.
