Robert A. Brooks
1979, Open-File Report 79-1238
This report contains material presented at the Uranium Leach Conference, which was held in Vail, Colo., August 25-27, 1976. The purpose of the presentation was to summarize some important geological concepts to a largely nongeological audience involved in the in situ extraction of uranium from buried uranium ore deposits. The...

Water resources of the Santa Rosa Indian Reservation and vicinity, Riverside County, California
Anthony Buono, W. R. Moyle, Patricia Dana
1979, Open-File Report 79-1172
Additional water for irrigation is needed by the Santa Rosa Indian Reservation, Riverside County, California. Water in the area is derived from precipitation, which averages 12 inches annually, on three subbasins nearly surrounding the 17-square-mile reservation. No ground water flows in from outside the area. A supply well that taps...
An appraisal of pumping effects on the Edgeley Aquifer, La Moure County, North Dakota, as determined by a digital model
M. R. Burkart
1979, Open-File Report 79-748
A finite-difference digital model simulated hydrologic conditions in the Edgeley aquifer, which is an unconfined glacial-drift aquifer. The calibrated model supported the hypothesis that under natural steady-state conditions, recharge is from precipitation and discharge is through evapotranspiration. This hypothesis was further supported by comparing simulated water levels to observed water...
Surface water environment in the area of the San Juan Basin regional uranium study, New Mexico, Colorado, Arizona, and Utah
Mark William Busby
1979, Open-File Report 79-1499
Streamflows in the lowland areas of the San Juan Basin are highly variable, responding to short-duration, high-intensity thunderstorms occurring in the late spring and summer. The thunderstorms can cause floods of large magnitude, but of localized extent. Most streams of the lowlands are ephemeral or intermittent. Streams of the high...

Radioactive springs geochemical data related to uranium exploration: basic data and use of multivariate factor scores
Robert Allen Cadigan, J. Karen Felmlee
1979, Open-File Report 79-1302
Radioactive springs and wells at 33 localities in the States of Colorado, Utah, Arizona, and New Mexico have been studied and sampled to obtain geochemical data to determine whether such data are useful in a uranium exploration program. Most samples were collected from mineral-rich springs probably related to hydrothermal systems...
Biological and microbiological assessment of the upper Chattahoochee River basin, Georgia
Bruce W. Lium, J. K. Stamer, T. A. Ehlke, R.E. Faye, R.N. Cherry
1979, Circular 796
Biological and microbiological studies were conducted by the U.S. Geological Survey as a part of the Intensive River-Quality Assessment studies of the upper Chattahoochee River basin, Georgia. Phytoplankton concentrations in cells per milliliter (cells/mL) were generally higher downstream from Atlanta than upstream. The highest concentrations, mostly blue-green algae, occurred in...

Background information to accompany folio of geologic, mineral resource, geochemical, aeromagnetic, and gravity maps of the Hillsboro and San Lorenzo quadrangles, Sierra and Grant Counties, New Mexico, with sections on geochemistry and geophysics
David Carl Hedlund, K. C. Watts, Henry V. Alminas, Jeffrey C. Wynn
1979, Circular 808
The Hillsboro and San Lorenzo 15-minute quadrangles of southwestern New Mexico have been mapped at a 1:48,000 scale and selected mineralized areas within these quadrangles have been mapped in greater detail. This area of about 550 mi2 (1,424 km2) is within the southern part of the Black Range and includes...
Introduction to monitoring dynamic environmental phenomena of the world using satellite data collection systems, 1978
William Douglas Carter, Richard W. Paulson
1979, Circular 803
The rapid development of satellite technology, especially in the area of radio transmission and imaging systems, makes it possible to monitor dynamic surface phenomena of the Earth in considerable detail. The monitoring systems that have been developed are compatible with standard monitoring systems such as snow, stream, and rain gages;...
