U.S. Geological Survey, Greater Everglades Science Initiative (Place-Based Studies)
Fiscal Year 2003 Project Summary Report
Project Start Date: October 1, 1999 Project End Date: September 30, 2005
Web Sites: sofia.usgs.gov
Location (Subregions, Counties, Park or Refuge): Southern Florida (including and south of Charlotte, Glades, Okeechobee, and St. Lucie Counties)
Funding Source: USGS's Greater Everglades Science Initiative (PBS)
Project Personnel: Student
Supporting Organizations: U.S. Army Corp of Engineers and South Florida Water Management District
Associated / Linked Projects: CERP ASR Regional "Preliminary Hydrogeologic Framework"; PBS/CERP ASR Coordination Activity; and CERP ASR Regional "Geochemistry Data and Literature Search and Review"
Overview & Objective(s): Aquifer storage and recovery (ASR) has been described as "the storage of water in a suitable aquifer through a well during times when water is available, and recovery of the water from the same well during times when it is needed". Water can be stored in aquifers with poor water quality. Precedence for ASR in southern Florida has been set by wells constructed at over 30 ASR sites, mostly by local municipalities or counties in coastal areas. The Upper Floridan aquifer is the aquifer of interest to the Comprehensive Everglades Restoration Plan (CERP) and is the aquifer being used at 22 out of 27 sites. This aquifer is brackish to saline in south Florida, which can have a large impact on the recovery of the fresh or potable water recharged and stored.
The objectives of this study are to: (1) inventory and assess the strengths and weaknesses of available hydrogeologic, hydraulic, hydrochemical, well construction, and cycle test information at existing ASR sites, (2) conduct a critical review of hydrogeology on a site-by-site basis and relate to existing regional hydrogeology frameworks, (3) identify hydrogeologic, design, and management factors which locally or regionally constrain the efficient storage and recovery of fresh water within the Upper Floridan aquifer, and (4) conduct a comparative analysis of the performance of all ASR sites having adequate data.
Status: This six-year study is divided into two phases, the first of which was two years long. The first phase laid the groundwork for data inventory, review, and analysis, and the second will allow for collection of additional data as it becomes available, expand the delineation of the hydrogeologic framework at each site, and perform a more complete comparative analysis of ASR sites. The study is in the second phase. Data collection and inventory is continuing.
Recent & Planned Products: The major products from this study will be two USGS Water-Resources Investigation Reports, one for each phase. The first of these, "Inventory and review of aquifer storage and recovery in southern Florida", WRIR 02-4036, was published in May 2002. The second report will be a WRIR to be published in FY05.
Relevance to Greater Everglades Restoration Information Needs: Aquifer storage and recovery (ASR) in south Florida is proposed on a large scale in CERP as a cost-effective water-supply alternative that can help meet needs of agri-cultural, municipal, and recreational users while providing the water critical for Everglades ecosystem restoration. In CERP plans have been made to utilize ASR on an unprecedented scale. Results of this study will help the managers of the CERP program in locating, designing, constructing, and cycle testing ASR wells. These results will help establish a standard cycle testing protocol that can be used to measure the performance of individual CERP wells or clusters of wells.
