Analysis of trends in water-quality data for water conservation area 3A, the Everglades, Florida
Rainfall and water-quality data bases from the South Florida Water Management District were used to evaluate water quality trends at 10 locations near or in Water Conservation Area 3A in The Everglades. The Seasonal Kendall test was applied to specific conductance, orthophosphate-phosphorus, nitrate-nitrogen, total Kjeldahl nitrogen, and total nitrogen regression residuals for the period 1978-82.

Simulation of tidal flow and circulation patterns in the Loxahatchee River Estuary, southeastern Florida
Results of a two-dimensional, vertically averaged, computer simulation model of the Loxahatchee River estuary show that under typical low freshwater inflow and vertically well mixed conditions, water circulation is dominated by freshwater inflow rather than by tidal influence. The model can simulate tidal flow and circulation in the Loxahatchee River estuary under typical low freshwater inflow and

Effluent migration from septic tank systems in two different lithologies, Broward County, Florida
Two septic tank test sites, one in sand and one in limestone, in Broward County, Florida, were analyzed for effluent migration. Groundwater from shallow wells, both in background areas and hydraulically down-gradient of the septic tank system, was sampled during a 16-month period from April 1983 through August 1984. Water quality indicators were used to determine the effluent affected zone near th

Chemical characteristics of water in the surficial aquifer system, Dade County, Florida
Geohydrologic test drilling was conducted throughout Dade County to describe the chemical characteristics of water from geohydrologic units in the surficial aquifer system. Water quality analysis of samples collected from the test wells completed in central Dade County indicates that the Biscayne aquifer (unit A), the upper clastic unit of the Tamiami Formation (unit B), and parts of a limestone,

Estimated water use in St. Croix, U.S. Virgin Islands, October 1983-September 1985
St. Croix is the largest of the U.S. Virgin Islands, with a land area of 82 square miles. The island is located about 60 miles east-southeast of Puerto Rico and about 40 miles south of St. Thomas and St. John (fig. 1). St. Croix has experienced a dramatic increase in its population over the last 25 years, growing from about 15,000 inhabitants in 1960 to about 54,000 in 1985 (personal communication

Use of borehole neutron logs to estimate moisture content in the unsaturated zone of an alluvial aquifer
he neutron borehole logging tool was calibrated for the determination of moisture content in theunsaturated zone of an alluvial aquifer. A continuous core sample was collected to a depth of 15 ft from the unsaturated zone.Moisture content and other soil properties were determined by standard soil-laboratory techniques. The neutron logs profile was correlated to moisture content. The first correlat

Estimating ground-water influx to a portion of the Rio Grande de Manati River basin in Puerto Rico through the measurement of 222Rn
Water has become a critical commodity in the Caribbean Region. In spite of a relative abundance of rainfall even on the smaller islands, the region is faced with severe seasonal shortages as well as increasing water quality problems. The supply of thewater needs in the area will become even more critical as economic development accelerates and the population continues to increase. The development

Water-quality data for the ground-water network in eastern Broward County, Florida, 1983-84
During 1983-84, ground water from 63 wells located at 31 sites throughout, eastern Broward County, Florida, was sampled and analyzed to determine baseline water-quality conditions. The physical and chemical parameters analyzed included field measurements (pH and temperature), physical characteristics (color, turbidity, and specific conductance), major inorganic ions, nutrients (nitrogen, phosphoru

Hydrogeologic framework of the Floridan aquifer system in Florida and in parts of Georgia, Alabama, and South Carolina
The Floridan aquifer system of the Southeastern United States is comprised of a thick sequence of carbonate rocks that are mostly of Paleocene to early Miocene age and that are hydraulically connected in varying degrees. The aquifer system consists of a single vertically continuous permeable unit updip and of two major permeable zones (the Upper and Lower Floridan aquifers) separated by one of sev

Chemical effects of highway runoff on the surficial aquifer, Broward County, Florida
In many areas of Broward County, swales are commonly designed to accept stormwater runoff from highways. Two sites adjacent to heavily traveled highways were studied to determine if stormwater percolating through unsaturated sand underlying the swales may affect the quality of water in the Biscayne aquifer. Concentrations of selected chemicals common in highway runoff were measured in swale stormw
