The U.S. Geological Survey (USGS), in cooperation with Miami-Dade County, mapped the approximate inland extent of saltwater intrusion in eastern Miami-Dade County in 2018. This approximation required acquisition and compilation of relevant data collected by the organizations: Florida Department of Environmental Protection (FDEP), Florida Keys Aqueduct Authority (FKAA), Florida Power & Light Company (FPL), MacVicar Consulting Inc., Miami-Dade County Regulatory and Economic Resources (MD-RER), the South Florida Water Management District (SFWMD), and the USGS. Data from the selected monitoring wells were entered into a geographic information system (GIS) for analysis and mapping. The approximate saltwater interface is represented by the 1,000-mg/L isochlor at the base of the Biscayne aquifer. The word "approximate" is used because the spatial distribution of monitoring wells is generally insufficient to create a precise representation.

Map of the approximate inland extent of saltwater at the base of the Biscayne aquifer in Miami-Dade County, Florida, 2018
The inland extent of saltwater at the base of the Biscayne aquifer in eastern Miami-Dade County, Florida, was mapped in 2011, and it was mapped in the Model Land Area in 2016. The saltwater interface has continued to move inland in some areas and is now near several active well fields. An updated approximation of the inland extent of saltwater has been created by using data collected during March - Connect
