Date Issued:

Summary:
The purpose of this report is to present the analysis of the hydrogeology and its effect on the potential for saltwater intrusion. Water quality and water levels have been monitored at two coastal well sites and are compared with tidal fluctuations. The comparisons in the report pertain to lag times and dampening effects as a result of the environmental characteristics between the wells and the gulf. Also described, as a result of data collection at the well sites, are analyses supporting flow in the zone of transition based on equations in Hubbert. The report also describes the models that were developed to simulate ground-water flow and the transport of solute in the ground-water flow system. Solute-transport model results are presented that show the position of the freshwater-saltwater interface based on nonunique sets of hydraulic conditions used as input data for the model simulations. The study area consists of two coastal sites: (1) Aripeka in Hernando County, 40 miles northwest of Tampa ; and (2) Rubonia in Manatee County, 25 miles south of Tampa. Each site has a focal point that consists of a ROMP well completed to the base of the Upper Floridan aquifer. Each ROMP well was tested to determine the hydraulic characteristics of the aquifer, logged to determine borehole characteristics and the nature of the freshwater-saltwater transition zone, and finished with several piezometers open to separate zones.
