Principal aquifers can contribute radium to sources of drinking water under certain geochemical conditions [More info]
Knowledge of the geochemical processes controlling radium occurrence in groundwater may help water-resource managers anticipate and minimize human exposure to this cancer-causing element.
PDF Rare earth elements--End use and recyclability [More info]
Rare earth element use is changing with technology. This report explains how we use them and the prospects for recycling these important commodities.
PDF The future of rare earth elements--will these high-tech industry elements continue in short supply? [More info]
Presentation describing uses of rare earth elements, why they are important, where they occur and are produced, and aspects of the economics of production and consumption with emphasis on sites that might be developed for production.
PDF The principal rare earth elements deposits of the United States-A summary of domestic deposits and a global perspective [More info]
Explains the geologic setting in which these deposits are found, with information about production and the processes used to extract these valuable mineral resources.
PDF A methodology for conducting national-scale alluvial diamond resource potential and production capacity assessments, with a focus on artisanal mining [More info]
Geologic evidence, combined with geographical data and analyized through a geographic information system allows us to compare production statistics with likely resource estimates.
PDF Application of the SPARROW watershed model to describe nutrient sources and transport in the Missouri River Basin [More info]
Maps and diagrams showing how the mathematical model predicts the distribution of various pollutants within a large watershed.
Arsenic in ground water of the United States [More info]
Arsenic is a naturally occurring element in rocks, soils, and the waters in contact with them. It is found in ground water as the result of minerals dissolving from weathered rocks and soils. This site links to data, maps, and more.
PDF Assessing the vulnerability of public-supply wells to contamination: Rio Grande aquifer system in Albuquerque, New Mexico [More info]
Explains the natural and human-affected factors that determine the concentration of contaminants in groundwater, especially where the concentration is different at the surface than at depth, and where pumping varies with time.
PDF Beryllium--important for national defense [More info]
How this element is used, where we get it, and prospects for worldwide supply and demand.
