    • Summary tables for the approximate inland extent of saltwater intrusion at the base of the Biscayne aquifer in 2022, Miami-Dade County, Florida

    Metadata Updated: January 7, 2026

    Tables were created to summarize well information, maximum chloride concentrations and specific conductance data sourced from Florida Keys Aqueduct Authority (FKAA), Florida Power and Light Company (FPL), MacVicar Consulting Inc., and the U.S. Geological Survey (USGS) during 2022. The summary tables here provide the information used to create the 1,000-mg/L isochlor in ArcGIS Pro. A table listing the USGS sites used to develop a regression between chloride concentration and specific conductance is also included in this release.
