Aquifer garage and restoration (ASR) is a method in which water is recharged via wells to an aquifer and extracted for helpful use at a few later time from an analogous wells. ASR is proposed as an incredible water garage part within the entire Everglades recovery Plan (CERP), constructed together via the U.S. military Corps of Engineers (USACE) and the South Florida Water administration District (SFWMD). The plan could use the higher Floridan aquifer (UFA) to shop up to 1.7 billion gallons in keeping with day (gpd) (6.3 million m3/day) of extra floor water and shallow groundwater in the course of rainy sessions for restoration in the course of seasonal or longer-term dry classes, utilizing approximately 333 wells. ASR represents approximately one-fifth of the whole predicted fee of the CERP.
Aquifer garage and restoration within the entire Everglades recovery Plan examines pilot undertaking from the point of view of adaptive overview, i.e., the level to which the pilot tasks will give a contribution to approach knowing which may increase layout and implementation of recovery undertaking parts. This record is a critique of the pilot tasks and similar studies.

Will the pilot studies provide the necessary data on rock properties for this analysis? If not, what additional studies are planned to fill the gaps? Cores will be obtained from the overlying confining units and from the ASR storage zone for laboratory analysis and determination of petrophysical properties. • Will a regional scale flow model of ASR system operation be adequate to predict local pressure buildups in the vicinity of injection wells for the purpose of evaluating fracture potential?
The CROGEE recommends that ecotoxicological studies, including long-term bioassays conducted at the field scale, be undertaken during the period of the pilot program to evaluate the ecological impacts of water quality changes resulting from broad use of ASR water to supplement inflows to the Everglades during droughts. Water recharged to ASR wells will come primarily from Lake Okeechobee and other impoundments. The source waters and surrounding lands can and should be managed to minimize the occurrence of pathogens in the water being pumped down the wells.
3. Advantages and disadvantages of using short or long open intervals in ASR wells. Short intervals may simplify aquifer management and minimize in-well circulation, but may limit recharge rates. 4. Design of monitoring wells to allow monitoring of "bubble" evolution, to evaluate potential leakage across confining units, and to assess well interference effects for pilot clusters. 5. Availability of models to simulate site-scale processes for comparison with monitoring data collected during cycle testing.
