Trends and Fluctuations in the Potentiometric Surface of the Floridian Aquifer, West-Central Florida 1961-80

Description: From introduction: This report describes the long-term and short-term trends and fluctuations of the potentiometric surface of the Floridan aquifer. Data shown include: (1) annual rainfall and departure from average rainfall at St. Leo and Arcadia from 1961 through 1980, and hydrographs of selected wells; and (2) maps that show change in the potentiometric surface of the Floridan aquifer from January 1964 to May 1969, from May 1969 to May 1975, from May 1975 to may 1980, from September 1975 to … more

Hydrologic Relations Between Lakes and Aquifers in a Recharge Area near Orlando, Florida

Description: 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 diff… more

Ground-Water Resources of Coastal Citrus, Hernando and Southwestern Levy Counties, Florida

Description: 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.

Aquifer Test Results, Green Swamp Area, Florida

Description: From abstract: "An aquifer test conducted in the Green Swamp area December 15-16, 1975 was designed to stress the uppermost part of the Flordian aquifer so that the leakage characteristics of the overlying confining bed could determined." This report includes those results.

Analog-Model Simulations for Secondary Canal Controls and Forward Pumping Water-Management Schemes in Southeast Florida

Description: 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.

Water-Resources Setting, Martin County, Florida

Description: 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.

A Digital Model of the Floridian Aquifer, North of Tampa, Florida

Description: 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.

Relation Between Freshwater Flow and Salinity Distributions in the Alafia River, Bullfrog Creek, and Hillsborough Bay, Florida

Description: From analysis: "Data on streamflow, tide stage, specific conductance, and chloride concentrations were collected in the Alafia River and Bullfrog Creek to describe the salinity and physical characteristics of the saltwater wedge." It contains maps, graphs, and tables.

Potential for Downward Leakage to the Floridan Aquifer, Green Swamp Area, Central Florida

Description: 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.

Analysis of Selected Benthic Communities in the Florida Everglades with Reference to Their Physical and Chemical Environment

Description: 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.

Experimental Study of Artificial Recharge Alternatives in Northwest Hillsborough County, Florida

Description: 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 effe… more

Chemical, Physical, and Radiological Quality of Selected Public Water Supplies in Florida, November 1977-February 1978

Description: 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 c… more
