Application of Thermal Imagery and Aerial Photography to Hydrologic Studies of Karst Terrane in Missouri

Description: From abstract: Planning waste-disposal facilities and impoundments is complicated by karst carbonate terrane in the Ozarks. Thermal imagery (8-13 micrometer wavelength) and color infrared photography aid in identifying losing streams, sinkholes and hydrologic conditions encouraging collapse. Imagery and photography were acquired in Greene and Reynold Counties, Mo., in March 1972 and June 1973. Differences in thermal levels correlating with losing and gaining reaches of Logan Creek valley, Reyno… more

Buried Aquifers in the Brooten-Belgrade and Lake Emily Areas, West-Central Minnesota -- Factors Related to Developing Water for Irrigation

Description: Purpose and scope: The purpose of this report is to determine, as far as possible, the occurrence of buried aquifers and to describe their hydrologic characteristics and water-yielding capability. The evaluation is based mainly on 44 test holes drilled specifically for this investigation. These test holes are too widely spaced to correlate individual aquifers. Such correlation must await more detailed closely spaced test drilling. Forty-two test holes were drilled in the Brooten-Belgrade area; … more

Carnotite Resources of San Miguel Bench, Montrose County, Colorado

Description: Abstract: San Miguel bench includes about 4 square miles in the southern part of T. 48 N., R. 17 W., New Mexico principal meridian, Montrose County, Colorado. Production of carnotite ore from the area has been about 15, 000 short tons having an estimated average graderof 0. 31 percent U3O8,and 1. 6 percent V2 05 Nearly all of the carnotite deposits occur in a single-continuous sandstone bed near the top of the Salt Wash member of the Jurassic Morrison formation. These deposits consist chiefly o… more

Chattanooga Shale Investigations Along the Sequatchie Anticline of Tennessee and Alabama

Description: From abstract: "In 1953 the Chattanooga shale in the Sequatchie anticline was tested for its uranium content by seven diamond drill cores. Concurrent with the drilling, geologic field work was done to determine the distribution, thickness, and structural setting of the shale." The report contains information regarding location and drainage, geology, the drilling program, subdivisions of the Sequatchie anticline, and unpublished reports.

Chattanooga shale investigations along the Sequatchie anticline of Tennessee and Alabama

Description: "The results of an investigation of the Chattanooga shale along the Sequatchie anticline of Tennessee and Alabama are summarized in this report. The project was of an exploratory nature designed to 1) obtain fresh core samples from areas where analyses of outcrop samples showed uranium contents as high or higher than those of the Youngs Bend area in DeKalb County, Tenn.; 2) learn more about the distribution and thickness of the shale in those areas and, if necessary, do some geologic mapping; 3… more

Chemical and Biological Quality of Selected Lakes in Ohio--1976 and 1977

Description: From abstract: "Twenty-eight Ohio lakes (fourteen per year) were sampled by the U.S. Geological Survey and Ohio Environmental Protection Agency for water-quality characteristics during the spring and summer of 1976 and 1977." It contains maps, graphs, and tables.

Chemical and Physical Characteristics of Precipitation at selected Sites in Florida

Description: From abstract: This report critically reviews historical precipitation data collected by the U.S. Geological Survey and concludes that the while the data "may reflect local atmospheric quality conditions they likely do not define baseline conditions from a regional perspective." It contains maps, graphs, and tables.

Digital Model Simulation of the Glacial-Outwash Aquifer at Dayton, Ohio

Description: From introduction: The specific purpose of the digital model study was to develop a better understanding of the aquifer system and to show how it responds to various pumping stresses. The scope of the study was to develop a single-transmissive-layer model that could be used to evaluate the effects proposed ground-water development schemes would have on water levels.

Distribution of Nitrate in the Unsaturated Zone, Highland-East Highlands Area, San Bernardino County, California

Description: From abstract: "This study was made to describe the distribution of inorganic nitrogen and other chemical constituents and nitrogen-using bacteria in the unsaturated zone, to relate nitrogen occurrences, in a general way, to present and historical land use, and to attempt to predict nitrogen concentrations in ground water after recharge" within the Highland-East Highlands area of San Bernardino County, California. It includes maps, graphs, and tables.
