The dataset represents the DBHYDRO Monitoring Stations in Southern Florida.All locations are monitoring station at which SFWMD, United States Geological Survey (USGS), United States Army Corps of Engineers (USACE), or another cooperating agency as indicated in the data set, are monitoring, or have monitored environmental parameters. This inventory of locations and activities is based on the contents of the SFWMD DBHYDRO corporate environmental database. Activity types include flow, rainfall, stage (water level), weather, well, or water quality. The water quality activities are further sub-divided into categories of convenience.This data set is derived from the database view in the DBHYDRO database dmdbase.all_stations_activity_kml_vw. This DBHYDRO view consolidates the information from 16 underlying relational database tables, some of which are recreated nightly to summarize information for ready-retrieval. The business rules of 1) what parameters constitute what activity types, 2) what parameters constitute what activity sub-types, and 3) what determines active and inactive status are thus maintained at the origin of the data.The environmental monitoring application is designed to allow customers to find where and what we monitor and to provide access to time series data archived for those locations. This application supports our water quality, applied sciences, regulation, and permitting business.

An aquifer test (or a pumping test) is conducted to evaluate an aquifer by "stimulating" the aquifer through constant pumping, and observing the aquifer's "response" (drawdown) in observation wells. Aquifer testing is a common tool that hydrogeologists use to characterize a system of aquifers, aquitards and flow system boundaries https://en.wikipedia.org/wiki/Aquifer_test. At SFWMD, APT data is used to assist the regulatory permit review and water supply planning processes. The feature class is created thru ETL nighthly using the Oracle wrep database view: DMDBASE.WELL_APT_TEST_INFO_VW.

The information provided in this dataset is categorized/symbolized as either 1) the depth range to which a well or borehole has been drilled or 2) the aquifer or activity status of monitor wells having attached time series data. Only the locations of well/borehole stations currently registered in the SFWMD DBHYDRO database are available for viewing through this mapping application. The inventory of stations in DBHYDRO include wells installed and boreholes drilled by or on behalf of the SFWMD, United States Geological Survey (USGS), United States Army Corps of Engineers (USACE), state, county and local government agencies, regulated utilities, and oil & gas companies for various purposes. NOTE: This data-set was compiled for the purpose of aiding groundwater resource evaluations.Many of the wells/boreholes owned and/or operated by SFWMD or other entities are included in DBHYDRO, but it is not, and should not be viewed as a comprehensive well inventory. The web layer is created daily using an Extract-Transform-Load (ETL) on the SFWMD wrep Oracle database view “DMDBASE.WELL_MAP_ROLLUP_VW” which itself consolidates information from multiple database tables to produce the map view. The web layer symbolized by the monitoring status and depth range can be customized by filtering on specific attributes. Fields for attributes include, but are not limited to: water supply planning region, county, watershed, water management district, agency, purpose, status (active or inactive), aquifer system or specific aquifer within a system. Each well location is linked to its corresponding station in DBHYDRO from which a variety of data and information on a well can be obtained. These data and information include water level and water quality time series monitoring data, depth, well construction, hydrostratigraphy, lithology, geophysical logs, hydraulic characteristics, and technical reports.The following fields are available for filtering:- Station: The DBHYDRO database station name associated with the well.- Agency: The agency primarily responsible for the monitoring data (The agency to whom data is most recently attributed)- Aquifer: The specific aquifer monitored if applicable- Aq_System: The more general aquifer system monitored if applicable- Depth Drilled: The depth to which the borehole was drilled.

These data are a compillation of data from multiple sources including South Florida Water Management District (SFWMD) DBhydro web database, United States Environment Protection Agency Regional, Environmental Monitoring and Assessment (REMAP), Everglades Soil Mapping (ESM), and Florida Coastal Everglades Long Term Ecological Research (FCE-LTER). The matrix of these data were compiled for soil, surface water, floc, and plants where the nutrients are counted for total phosphorus, total carbon, and bulk density. When downloading the data from DBhydro, only regularly collected samples (SAMP) were included these data. As per DBhydro metadata, the regular samples were collected monthly by grab method throughout the year from 2004 to 2016 for SFWMD monitoring stations across the EPA. All flagged and field quality controlled values were excluded to avoid the duplication of data. In order to maintain the quality assurance/ quality control (QA/QC) the method detection limit for water TP was fixed at 2 µg/L by the SFWMD. This data set were used to assess the decadal trend of TP concentration in surface water and soil in EPA. Available data from 2004 to 2014 was collected for soils and from 2004 to 2016 for water to understand a decade of trends. Both Geographic Information System (GIS) and statistical data analysis were applied to determine changes in water quality and soil chemistry. These data are the basis for Shishir Sarker's Master's thesis.

The Picayune Strand Restoration Project (PSRP) monitoring effort is supplemented with meteorological data from one active weather station (Southern Golden Gate Estates), as well as four active and three inactive rainfall stations located throughout the project area and near vicinity. Data for these stations are available in DBHYDRO; the current dataset includes DBKEY links for daily mean or sum values primarily recorded with Campbell Scientific Measurement and Control Dataloggers. Two older, inactive stations recorded data with Belfort Rain Gauges: Fakahatchee Strand and East Golden Gate Estates. Copeland Tower station historically recorded data via standard rain can, and currently utilizes a tipping bucket. Additional data for the majority of stations are accessible in DBHYDRO with other DBKEYS; these data include breakpoint, daily maximum, and daily minimum values recorded with either Campbell Datalogger, Belfort Rain Gauge, or NRG rain gauge augmented with radar-based rainfall data. Two of the inactive stations were operated by the Florida Forestry Service: Copeland Tower (rain can) and Miles City Tower. All active stations are operated and maintained by SFWMD staff.

This groundwater monitoring project will evaluate potential effects resulting from the Picayune Strand Restoration Project (PSRP) before, during and after restoration of the historic hydrologic regime. In 1999, the SFWMD began continuous real-time monitoring of two Lucky Lake freshwater wells located just south of I-75 in Southern Golden Gate Estates (SGGE). During 2003-4, the SFWMD began monitoring 23 SGGE freshwater wells located throughout the PSRP north of Tamiami Trail. Three additional SGGE estuarine wells were installed below Tamiami Trail in the Ten Thousand Islands National Wildlife Refuge (TTINWR) and Fakahatchee Strand Preserve State Park (FSPSP) coastal marshes in 2006. The 28 wells are located in east-west bands across the project area and into adjacent lands being hydrologically affected by the PSRP canal system. Well sites are also distributed throughout different vegetative habitats to assess whether a suitable hydrology will be restored to the major types of pre-development plant communities. Each well provides data to document surface and surficial aquifer water levels and hydroperiods. The estuarine wells also record salinity, water temperature and specific conductivity. Well data is sent to the SFWMD DBHYDRO database at 15-minute intervals; the current dataset includes DBKEY links for daily mean values recorded with Campbell Scientific Measurement and Control Dataloggers. Additional breakpoint data for these wells are accessible in DBHYDRO with other DBKEYS. This monitoring began during baseline monitoring for the project and will be continued, at a minimum, through the year 2050. The well data is analyzed annually to determine water level stages and hydroperiods. These results will be used to assess the effects of the project on the inland plant and animal communities, allowing identification of potential project modifications needed to further improve restoration benefits.

Chloride data used in the approximation of the 250 mg/L isochlors for the east coast and west coasts of Florida for surface water and the water table, surficial, Lower Tamiami, Sandstone, and Mid-Hawthorn aquifers. Well and chloride data were obtained from USGS and SFWMD records. The isochlor is based on the maximum chloride value for the period of March/April/May 2024. Chloride and well data from the SFWMD have been furnished by Permittees and have not been validated. Chloride and well data from the USGS are available via https://waterdata.usgs.gov/nwis and may also be available in the District’s DBHYDRO database https://my.sfwmd.gov/dbhydroplsql/show_dbkey_info.main_menu. The 250 mg/L isochlors for the east and west coasts are compiled in a separate line feature class called, "Merged Isochlor, 2024".

This is a merged set of Isochlor line features into single feature class compiled from the original series of individual 2024 isochlor data layers. Approximate 250 mg/L isochlor for Broward, Palm Beach, Martin, St. Lucie, Lee and Collier Counties. Well and chloride data were obtained from USGS and SFWMD records. The line marks an approximation of the farthest inland extent of the saltwater interface as defined by the 250 mg/L chloride concentration and/or the farthest inland extent of saline surface water. The isochlor is based on the maximum chloride value for the period of March/April/May 2024, with minor exceptions (denoted by an * at the end of the well table at the bottom of the published maps).Chloride and well data from the SFWMD have been furnished by Permittees and have not been validated. Chloride and well data from the USGS are available via https://waterdata.usgs.gov/nwis and may also be available in the District’s DBHYDRO database https://my.sfwmd.gov/dbhydroplsql/show_dbkey_info.main_menu.The chloride wells used for this project are compiled in a separate point feature class called, "Chloride Concentration Control Points, 2024".
