Comprehensive Everglades Restoration Plan (CERP)
The overarching objective of the Comprehensive Everglades Restoration Plan (CERP) is to transport sheet flow toward the Everglades National Park (ENP) , in a manner that more closely resembles natural wet-season/dry-season water level changes. Increased surface and groundwater flows in the study area (adjacent to ENP) are managed by water control structures, such as pump stations, gated culverts, and spillways that are planned or exist on maintained canals. These components primarily regulate surface water stage and flow for flood management purposes. However, the underlying groundwater flow component (or seepage) in the Biscayne Aquifer remains poorly understood. Surface-water and groundwater flow are tightly coupled in the Biscayne Aquifer. Therefore, until surface-water and groundwater level, flow rate, and direction are better quantified, it will be difficult to define that factors that result in successful hydrologic restoration (such as improved hydroperiods) for ENP.
L-31N Seepage Management Pilot Project (SMPP)
The purposes of the L-31N Seepage Management Pilot Project (SMPP) are to investigate technologies that can be used to control seepage from Everglades National Park (ENP) , while minimizing impacts to Miami-Dade County's West Well field. Further goals for the Project include assuring regional freshwater flows to Biscayne Bay as well as providing for other existing legal uses.

The SMPP is situated in an area of particularly high transmissivity within the Biscayne Aquifer , where it is desirable to control eastward seepage of groundwater, towards the urban area of Miami-Dade County and to improve water deliveries to the Northeast Shark River Slough within Everglades National Park.
This Project: Biscayne Aquifer Monitoring at L30 & L31
This project will characterize and quantify the changes in the surface water/groundwater hydrogeologic regime before, during, and after emplacement and operation of two major water-control structures adjacent to ENP: 1) a 35-ft deep, 2-mile long seepage cut-off wall currently under construction on the L-31N Levee; and 2) subsequent operational testing of a 500 cfs pump station (S-356) located on L-29 Canal just north of the cut-off wall (Figure 1). This series of tasks essentially defines a field-scale test to evaluate the hydrologic effects and effectiveness of water control structures on groundwater flow in the Biscayne Aquifer.
