From introduction: In this study on raw material sources of uranium the Southern Interstate Nuclear Board has catalogued all known occurrences of uranium and some references to thorium in a 17-state area (P1. 1). These occurrences have been evaluated as potential sources of uranium by the State Geological Surveys and the consultant group of SINB. Favorability guides have been applied to the known occurrences and recommendations have been made for future action by the states involved, federal agencies, or by industry. State recommendations are included in state-by-state summaries. The state reports were written either by personnel of the State Geological Surveys or were abstracted from State geological survey data by members of the consultant group...The purpose of this study was to compile information on and systematically assess uranium and other radioactive occurrences in the region. The SINB undertook the project because of its statutory, interstate capability as an extension of government in each of the 17 states, an arrangement that lends itself effectively to this cooperative undertaking.

Abstract: The three lakes investigated gain water- from adjoining water-table aquifer and lose water to Floridan aquifer by downward leakage. Net seepage (net exchange of water between lake and aquifers) can be estimated by equation S = AX + BY, where S is net seepage, X represents hydraulic gradient between lake and water-table aquifer, A is lumped parameter representing effect of hydaulic conductivity and cross-sectional area of materials in flow section of water-table aquifer, Y is head difference between lake level and potentiometric surface of Floridan aquifer, and B is lumped parameter representing effect of hydraulic conductivity, area, and thickness of materials between lake bottom and Floridan aquifer. If values of S, X, and Y are available for two contrasting water-level conditions, coefficients A and B are determinable by solution of two simultaneous equations. If the relation between lake- and ground-water level is same on all sides of the lake with regard to each aquifer and if X and Y are truly representative of these relations, then X and Y terms of equation provide valid estimates of inflow to lake from water-table aquifer and outflow from lake to Floridan aquifer.

From purpose and scope: The purpose of this investigation is to evaluate, through electrical analog model simulation, the effects of two specific water-management proposals in Dade County. Proposal one is the installation of a secondary control on Snake Creek Canal and proposal two is the forward pumping scheme.

From introduction: This report describes some basic principles of hydrology as they apply to Martin County. The major land features of the county are described first, then the hydrologic cycle and the county's surface-water and ground-water resource. Specific problems associated with population growth and the county's development, such as saltwater intrusion and water use, are sited and sections have been included in the report to deal with these problems.

From purpose and scope: The purpose of this report is to describe the development and calibration of a regional digital model of the Floridian aquifer in the Tampa Bay area. This model can be used to provide regional analyses of the effects of present and proposed pumping from the Floridian aquifer.

Report and geological survey. This report is on the effects of the domestic secondary-treated effluent used for irrigation of pastures near Lakeland, Florida. Includes a number of maps, tables, and other figures.

From introduction: For the purpose of this evaluation, which is qualitative, and which is based on an arbitrary numerical ranking of the thickness and hydraulic conductivity of the different materials involved, the intent was to include only the relatively pure sand beds, which would most readily store and transmit appreciable quantities of water and the clay beds, which would most effectively retard the downward movement of water to the Floridian aquifer.

This evaluation presents a proposal to drill more new wells away from the Atlantic Coast to avoid saltwater intrusion problems in the existing freshwater wells. It contains figures and maps.

This report presents results of a model evaluation for four estuaries in Pasco, Citrus, and Pinellas counties, Florida. It includes graphs, tables, and graphs.

This is a map of the southwest Florida aquifer.

From purpose and scope: The purpose of this investigation is to document the types of aquatic benthic organisms found within the Everglades and to determine the extent to which the chemical and physical character of surface water and bottom materials affect their distribution and community structure.

Abstract: Extensive water withdrawal from Floridian aquifer in the urban Tampa Bay area has induced leakage from the overlying surficial aquifer adversely effecting the water table and lake levels. Artificial recharge could reduce the impact of these adverse effects. Four experiments were conducted to investigate possible recharge alternatives; sinkhole recharge, water-spreading, connector wells, and subsurface-tile drainage to a deep well. Experiments indicate that all four methods can be effective. However, the sinkhole recharge experiment moved the greatest potential for draining the surficial aquifer. Combinations of the four methods could be used where potential exists for downward movement of water and sufficient unsaturated aquifer for water storage.

Abstract: Virtually all treated public water supplies sampled in Florida meet the National Inter-Primary and Proposed Secondary Drinking Water Regulations. These findings are based on a water-quality reconnaissance of 129 treated public supplies throughout the State during the period November 1977 through February 1978. While primary drinking water regulation exceedences were infrequent , lead, selenium, and gross alpha radioactivity in a very few water supplies were above established maximum contaminant levels. Additionally , the secondary drinking water regulation parameters--dissolved solids, chloride, sulfate, iron, color, and pH--were occasionally detected in excess of the proposed Federal regulations. The secondary regulations, however, pertain mainly to the aesthetic quality of drinking water and not directly to public health aspects.

From introduction: The purpose of this report is to show how hydrology and geology are applied in evaluating landfill sites in west-central Florida, and to illustrate a land disposal method of handling solid waste.

Purpose and scope: This reports presents the results of a 2-year investigation by the U.S. Geological Survey, in cooperation with the city of St. Petersburg, to evaluate geohydrologic conditions at a landfill in a coastal area. The report defines and describes the geologic and geohydrologic units underlying the landfill, and examines the controls these units exert on the flow and quality of surface and ground water in the area. The study increases the understanding of the geohydrologic aspects of landfill operations and will be helpful in the selection of future landfill sites in similar coastal areas.

Abstract: Ground water in the Myakka River basin area is obtained from a water-table aquifer and from five zones in an artesian aquifer. Wells in the water-table aquifer yield generally less- than 50 gal/min and dissolved solids concentration is less than 500 mg/1 except in coastal areas and the peninsula southwest of the Myakka River estuary. Wells in the Venice area that tap zone. 1 usually yield less than 30 gal/min. The quality of the water is good except in the peninsula area. Zone 2 is the most highly developed aquifer in the heavily populated coastal areas. Wells yield as much as 200 gal/min. In most areas, water is of acceptable quality.Wells that tap zone 3 yield as much as 500 gal/min. Fluoride concentration ranges from 1 to 3.5 mg/1. Zone 4 yields as much as 1,500 gal/min to large diameter wells. Except in the extreme northeastern part of the area water from zone 4 usually contains high concentrations of fluoride and sulfate. Zone 5 is the most productive aquifer in the area, but dissolved solids concentrations usually are too high for public supply except in the extreme northeast.Surface water derived from natural drainage is of good quality except for …
