The maximum, and 80th, 90th, and 96th percentiles of the annual maximums of daily water levels recorded at monitoring sites in and near Miami-Dade County, Florida, during the 1974-2009 water years. [≥, greater than or equal to; %, percent; GW, groundwater; NPS, National Park Service; SFWMD, South Florida Water Management District; USGS, U.S. Geological Survey. All data adjusted to the North American Vertical Datum of 1988. Latitude and longitude are in decimal degrees]

Statistical analyses and maps representing mean, high, and low water-level conditions in the surface water and groundwater of Miami-Dade County were made by the U.S. Geological Survey, in cooperation with the Miami-Dade County Department of Regulatory and Economic Resources, to help inform decisions necessary for urban planning and development. Sixteen maps were created that show contours of (1) the mean of daily water levels at each site during October and May for the 2000-2009 water years; (2) the 25th, 50th, and 75th percentiles of the daily water levels at each site during October and May and for all months during 2000-2009; and (3) the differences between mean October and May water levels, as well as the differences...

Statistics of daily water levels recorded during the 1990—2009 water years used to create maps of the water table in Miami-Dade County, Florida. [USGS, U.S. Geological Survey; All data adjusted to the North American Vertical Datum of 1988 (NAVD 88). Latitude and longitude are in decimal degrees. See appendix 8 for index map]

Time series electromagnetic-induction log (TSEMIL) datasets are collected from PVC cased or uncased monitoring wells to evaluate changes in water conductivity over time. TSEMIL datasets consist of a series of individual electromagnetic-induction logs collected at a frequency of months or years that have been compiled into a dataset by eliminating small uniform offsets in bulk conductivity between logs likely caused by minor variations in calibration. At depths where water conductivity is not changing through time, each log is typically within about ±15 mS/m of the median of the dataset at any given depth, which is within the stated repeatability specifications of the probe (Mount Sopris Instrument Co., Inc.,...

Excel table providing the daily water level data from the National Park Service, Everglades National Park, the South Florida Water Management District, and the U.S. Geological Survey during 1974-2009 prior to editing. [All data are in the original vertical datum provided by the collecting organizations (see row titled "Datum"). Data were retrieved from the databases of the National Park Service - Everglades National Park, South Florida Water Management District, and U.S. Geological Survey in July and August 2012. The row titled "Notes" describes the subsequent changes that were made during editing in 2012, such as the elimination of redundant or unusable site files and merging of datasets collected at the same site....

Edited daily water-level data recorded at monitoring sites in and near Miami-Dade County, Florida, during the 1974-2009 water years. [All data have been converted from the original vertical datum to the North American Vertical Datum of 1988 (NAVD 88). The row titled "Notes" describes some of the changes that were made, such as merging of data from the same site and deletion of anomalous data. Latitude and longitude are in decimal degrees. Dates are in month/day/year format.

Description of columns in the ArcGIS point file "Points for Maps" which provides the final statistics used to make the maps of mean daily water levels and maps of the 25th, 50th, and 75th percentiles of daily water levels during 2000–2009 in Miami-Dade County; and maps showing the differences in the statistics of water levels between 1990–1999 and 2000–2009.

The salinity of groundwater at the Florida Power & Light Company (FPL) Turkey Point Nuclear Plant in southeastern Florida is being evaluated. The power plant contains a large cooling canal system with warm water; which has salinities elevated above typical, natural surface water in southeastern Florida, circulating within the canals in the uppermost part the highly permeable karst carbonate Biscayne aquifer. The canal system is a closed system that does not discharge directly to fresh or marine surface water bodies. However, exchange between the canal system and groundwater has been postulated based on existing hydrologic information. A pilot study was conducted to determine if Continuous resistivity profiles could...
