From introduction: The purpose of this study was to determine the distance the tide-driven saline water from the ocean traveled upstream and to define the specific-conductance and chloronity gradients in the lower reaches of the Altamaha, Satilla, and St. Marys Rivers during the high spring tide and low-flow event.

From introduction: The purpose of this report is (1) to describe the geology, hydrology, and quality of water of Manatee County and (2) to evaluate the availability of surface and ground water for development. The report provides Manatee County, the Southwest Florida Water Management District, and the Florida Department of Natural Resources with a data base and an evaluation of the water resources of the area so that water-quality and water-resource problems and water-management and regulatory needs can be adequately defined and documented.

Partial abstract: "This report reviews the scope of a research effort initiated in 1974 at the U.S. Army Engineer Waterways Experiment Station with the objectives of (a) assessing the state of the art in geophysical cavity detection and delineation methodology and (b) developing new methods and improving or adapting old methods for application to cavity detection and delineation." This report discusses the geography, topography, site drilling tests, magnetic and microgravimetric surveys, and other information about the Medfor Cave site in Florida.

This report presents survey results designed to find chloride concentrations in the Floridan aquifer, the main source of freshwater for southwest Florida. It contains maps, graphs, and tables.

From introduction: The study is part of a continuing cooperative program with the Southwest Florida Water Management District to define and describe characteristics of the aquifer. Aquifer characteristics determined from the study will provide data necessary for regulatory agencies to more efficiently manage water supply and development. The study area includes 10 counties and parts of 6 other counties within the District.

Abstract: The Pinellas County landfill site is on a flat, coastal area characterized by a nearsurface water table. Part of the site is subject to tidal flooding; altitudes within the study area range from 8 to 12 feet above sea level. Three geohydrologic units underlie the landfill site. In descending order, these are: a surficial aquifer about 19 feet thick composed of sand and shell, a confining bed about 35 feet thick composed of marl and clay, and the Floridan aquifer composed of limestone. Landfill operations have not altered surface-water quality. Although leachate movement downward into the Floridan _aquifer is not indicated, vertical movement through the confining bed is about 0.005 foot per year. The rate of lateral movement of ground-water away from the site is about 1.2 feet per year; . however, the rate of movement along the boundary from the oldest section of the landfill through the surficial aquifer is about 20 feet per year. Peaks in concentration of selected chemical parameters and flow-rate analysis of water from trenches indicate the possibility of intermittent release of leachate from the landfill.

From introduction: This report explains how landfills can affect ground-water resources in a coastal environment. The report defines solid waste and briefly describes the four common methods for its disposal. The landfill method used in coastal west-central Florida is described in detail. It also presents hydrologic and geologic factors to be considered when locating landfills in a coastal environment and describes how to plan a water-quality monitoring program at a landfill site. Examples from other studies of the impact of landfills on ground water in coastal areas of west-central Florida are included.

Abstract: This report contains data and statistics on low-flow frequency for 254 stream-gagins stations on Florida streams and canals. The selected stations have 10 or more years of continuous record. A site description, a 10-year hydrograph, and a table of flow duration are presented for each station. A computed monthly 7-day, 10-year low flow is presented for stations when flow is not significantly altered by dams, increased or decreased significantly by diversion, or influence by tides.

From purpose and scope: In 1980, the U.S. Geological Survey, in cooperation with the Southwest Florida Water Management District, initiated an investigation to appraise the ground-water resources of coastal parts of Citrus, Hernando, and Levy Counties that are within the Southwest Florida Water Management District and to provide information necessary for the use and protection of the resource.

From purpose and scope: This report presents those results of the investigation which pertain to the hydrogeology and availability and quality of water from the sand-and-gravel aquifer. It discusses the hydrogeologic characteristics, hydraulic properties, potential yield, and water quality of the aquifer.

From purpose and scope: The U.S. Geological Survey, in cooperation with Lee County, conducted an investigation of the river in 1976-79. This investigation was planned to provide a broader base if information than heretofore available on the freshwater resources of the Caloosahatchee River basin, and in particular to provide information on water-quality conditions with emphasis on nutrients and algal growth. In addition to data collected during 1976-79, some earlier data collected by the U.S. Geological Survey were included to evaluate annual variation and trends.

From introduction: This report documents the results of the 1980 Florida water assessment made by personnel of the five Water Management Districts in a joint effort with U.S. Geological Survey personnel. The study was made as part of a statewide cooperative program with the Florida Department of Environmental Regulation, Northwest Florida Water Management District, St. Johns River Water Management District, South Florida Water Management District, Southwest Florida Water Management District, and the Suwannee River Management District.

From introduction: This report reviews descriptive background information of the Kings Bay area and presents data on currents, salinity, temperature, turbidity, suspended sediment, phytoplankton, and on the chemical and physical characteristics of bottom sediments. Water, salt, and suspended-sediment discharges are computed for consecutive ebbtides and floodtides that occurred during the November investigation.

From introduction: This report is part of a three-site assessment of water-quality conditions in areas of solid-waste disposal in Dade County. It is primarily intended to furnish county water planners and managers with specific water-quality information regarding the quality of landfill leachate, along with generalized observations on the quality impact on contiguous water resources due to leachate encroachment.

From purpose and scope: The primary purpose of the investigation was to measure both the concentrations and loads of selected water-quality parameters in runoff from the bridge surface during storms.

From purpose and scope: This prospectus report presents no original investigative results, but relies upon those of studies documented separately for the preparation of synopses of diverse topics related to cyclic injection and recovery of freshwater in that part of south Florida underlain by saline artesian aquifers. The report is intended to aid the U.S. Army Corps of Engineers and other water managers by addressing fundamental issues...

Abstract: The U.S. Geological Survey maintains a quality-assurance program based on the analysis of reference samples for its two water-analysis laboratories located in Atlanta, Georgia, and Denver, Colorado. Reference samples containing inorganic constituents are prepared at the U.S. Geological Survey's Ocala, Florida office and disguised as routine samples, and sent daily to each laboratory through other U.S. Geological Survey offices. The results are permanently stored in the National Water Data Storage and Retrieval System (WATSTORE), the U.S. Geological Survey's data base for all water data. These data are analyzed statistically for precision and bias. The results of these statistical analyses are presented for data collected during the 1981 calendar year. In addition, one sample containing known concentrations chlorophyll a were analyzed in both laboratories, and these results also are presented.

"The purpose of this report is to explain potentiometric surface maps and their value in assessing the resource, particularly during drought conditions. It is intended to convey a lay understanding of the process by which gains or losses of freshwater storage in the aquifer are determined."
