Chloride Data, 2009 (updated July 2015)

Chloride data used in the approximation of the 250 mg/L isochlors for the east coast and west coasts, water table, Biscayne, surficial, Lower Tamimai, Sandstone, and Mid-Hawthorn aquifers. 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. The isochlor is based on the average of available chloride values for the period of April/May 2009. 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 waterdata.usgs.gov/nwis.
