This report uses log analysis methods to analyze and compare "geologic and hydrologic data obtained from well tests and core studies," focusing specifically on the Edwards aquifer in Texas. It contains maps, tables, and figures.

This report examines the annual recharge to the Edwards Aquifer in San Antonio, Texas and how to collect annual recharge data. It includes maps and tables.

From introduction: This report presents the results of a preliminary study of the uranium favorability of lower and middle Eocene rocks in the Wilcox and Claiborne Groups in the Texas Gulf Coastal Plain. The project began October 1, 1976, and was completed March 1, 1977, by personnel of Bendix Field Engineering Corporation (BFEC) under the auspices of the U.S. Energy Research and Development Administration (ERDA).

From abstract: Results of a reconnaissance geochemical survey of the San Antonio Quadrangle , Texas are reported. Field and laboratory data are presented for 781 groundwater samples 541 stream sediment samples, and 331 stream water samples.

Abstract: Results of a reconnaissance geochemical survey of the Sherman Quadrangle, Texas; Oklahoma are reported. Field and laboratory data are presented for 718 groundwater and 715 stream sediment samples. Statistical and areal distributions of uranium and possible uranium related variables are displayed. A generalized geologic map of the survey area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed.

From abstract: Results of a reconnaissance geochemical survey of the Plainview Quadrangle, Texas are reported. Field and laboratory data are presented for 969 groundwater samples and 571 stream sediment samples.

From abstract: Results of a reconnaissance geochemical survey of the Emory Peak Quadrangle, Texas are reported. Field and laboratory data are presented for 193 groundwater samples and 491 stream sediment samples. Statistical and areal distributions of uranium and other possible uranium-related variables are displayed. A generalized geologic map of the survey area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed.

From abstract: Results of a reconnaissance geochemical survey of the Presidio Quadrangle, Texas are reported. Field and laboratory data are presented for 79 groundwater samples and 105 stream sediment samples. Statistical and areal distributions of uranium and possible uranium-related variables are displayed. A generalized geologic map of the survey area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed.

Data collected as part of the hydrogeological and stream sediment reconnaissance for the Sherman NTMS quadrangle including laboratory data on well water and stream sediments as well as field data.

Supplementary data containing geologic maps and analysis reports of the Wilcox and Claiborne Groups to accompany a report on uranium favorability in Texas.

This report summarizes the investigations of soil properties, aquatic biota, and wildlife held in the marshland and upland communities on dredged material behind a sandbag dike at Bolivar Peninsula, Galveston Bay, Texas.

The information provided in this report follows the investigations of the use of dredged material islands made by colonial nesting seabirds and wading birds in Texas initiated in October 1976.

From preface: "This report presents a summary of results of a 2.5-year field investigation (March 1975 to November 1977) of the feasibility and impact of developing marsh and upland habitat on dredged material at a site located at Bolivar Peninsula, Galveston Bay, Texas. The report summarizes baseline information derived before habitat development operations and results of post-development operations."
