These line features produced by the USGS represent an approximate inland extent of the saltwater interface along South Florida's East Coast over time. The approximate saltwater interface lines in Miami-Dade County are represented by the 1,000-mg/L isochlor at the base of the Biscayne Aquifer. |

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>These line features produced by the USGS represent an approximate inland extent of the saltwater interface along South Florida's East Coast over time. The approximate saltwater interface lines in Miami-Dade County are represented by the 1,000-mg/L isochlor at the base of the Biscayne Aquifer. These datasets were originally obtained from the USGS and then merged into a single feature class to combine the years dating back to 1904. In a separate effort, the SFWMD develops maps documenting the inland extent of the saltwater interface as defined by the 250 milligrams per liter (mg/L) chloride concentration in groundwater. This effort is done every 5 years for the East Coast and West Coast Aquifers excluding the Biscayne Aquifer in Miami-Dade. Those datasets are found in separeate feature classes for each year to date: Merged Isochlor 2009, Merged Isochlor 2014, and Merged Isochlor 2019. </SPAN></P><P><SPAN>Chloride and well data from the USGS are available via </SPAN><A href="https://waterdata.usgs.gov/nwis."><SPAN>https://waterdata.usgs.gov/nwis.</SPAN></A></P></DIV></DIV></DIV> |
