Report presenting accounts of testing saline water conversion and the economics thereof. This report covers the fifteenth and sixteenth Development Runs, which evaluated the following: the performance of the plant's double-fluted tube bundle and titanium tube bundle; the condensate handling-restrictions in the 5 effect module; a sump to sump brine transfer system modification; porcelain spray nozzles; enhanced surface tubes; and an oxygen scavenging system.

From Introduction: "The Sixth Annual Report presents a wide variety of information findings and recommendations concerning the Multiple-Effect VTE evaporation method of desalination. The included data are derived from the results obtained from operation, maintenance, and development studies conducted for the the U.S. Department of the Interior, Office of Saline Water, at Freeport, Texas. Not only are the technical, logistical, and economical evaluations for the Fiscal Year 1967 operations presented herein, but also the process and mechanical development program results as related to the process in particular, and desalination in general."

From introduction: "Report on the biological survey of Texas conducted over a number of years through collection of information and specimens. Focus on life zones and their subdivisions and on the mammals and reptiles of the state."

Abstract: Removal of water, oil, and gas from the subsurface in Harris and Galveston Counties, Texas, has caused a decline in fluid pressures, which in turn has resulted in subsidence of the land surface. Subsidence of the land surface at Seabrook is due principally to the removal of water. Significant subsidence of the land surface probably began after 1920, and a minimum of about 3.3 feet (1.0 m) and a maximum of about 4.3 feet (1.3 m) of subsidence had occurred at Seabrook by 1973. Probable future subsidence was calculated by two different methods for each of two different loading situations. In the first loading situation, case I, the artesian heads in the Alta Lorna Sand (Rose, 1943) and Evangeline aquifer would continue to decline at the respective rates of 8 feet (2.4 m) per year and 7 feet (2.1 m) per year until 1980 and then cease. In the second loading situation, case II, the artesian heads in the Alta Lorna Sand and Evangeline aquifer would continue to decline at rates of 8 and 7 feet (2.4 and 2.1 m) per year until 1990 and then cease.

Abstract: Removal of water, oil, and gas from the subsurface in Harris and Galveston Counties has caused declines in fluid pressures, which in turn have resulted in subsidence of the land surface. Subsidence of the land surface at Moses Lake is due principally to the removal of ground water in adjacent areas. Significant subsidence of the land surface at Moses Lake began after 1900, and as much as 1.8 feet (0.55 meters) of subsidence had occurred in the area by 1973. Probable future subsidence was calculated by two methods for two loading situations. In the first loading situation, case 1, the artesian head in the middle Chicot aquifer, in the Alta Lorna Sand (Rose, 1943), and in the Evangeline aquifer would continue to decline at respective rates of 1, 3, and 3 feet (0.3, 0.9, and 0.9 meters) per year until 1980 and then cease. In the second loading situation, case 2, the artesian head in the middle Chicot aquifer, in the Alta Lorna Sand, and in the Evangeline aquifer would continue to decline at respective rates of 1, 3, and 3 feet (0.3, 0.9, and 0.9 meters) per year until 1990 and then cease.

The objective of this project was to identify and delineated units and (or) facies that are favorable for uranium in the Upper Pennsylvanian and Lower Permian strata of north-central Texas and southwestern Oklahoma. Mapping of depositional systems in the subsurface was the main emphasis of the study.

From abstract: This report presents the results of a subsurface investigation of the Upper Eocene through Pliocene Series of the Rio Grande Embayment in the Gulf Coastal Plain of South Texas. The study was conducted for the Resource Division, Grand Junction Office, United Stated Atomic Energy Commission.

From objective and plan: The airborne data gathered were reduced using ground-based computer facilities to give the basic uranium, thorium and potassium equivalent gamma radiation intensities, ratios of these intensities, aircraft altitude above the earth's surface, total gamma ray and earth's magnetic field intensity, correlated as a function of geologic units indicated from available geologic maps. Results of analyses of these field data are presented as profile plots of the gamma radiation and earth's magnetic field.
