potential for ASR zones and confining units. This task will occur simultaneously with development of the hydrogeologic literature search. Following this task, three (3) large-diameter exploratory wells will be permitted and installed to better assess hydrogeologic characteristics, evaluate hydraulic capacity, and result in selection of the target ASR storage zone.
  • Will the pilot projects be adequate to develop a regional conceptual model suitable for translation into the numerical model that is intended to provide a preliminary assessment of regional effects of the ASR system?

Recognizing the importance of an understanding of regional issues, and the budget limitations of the pilot projects, USACE/SFWMD are now proposing to allocate funds to conduct a Regional Study in parallel with the pilot projects. The scope of the Regional Study is not yet defined, but will be refined based on CROGEE comments. The scope of the Regional Study will include development of a conceptual model from several sources including:

    1. Hydrogeologic literature search

    2. Automation of 30 FAS wells to assist in model calibration

    3. Hydrogeologic data from the 3 new monitor wells noted above

    4. Hydrogeologic data from the 3 new large-diameter exploratory wells

We believe these data are sufficient to develop a regional numerical model, but are aware that one can always make an argument that more data are needed.

  • If the pilot projects will not provide all of the necessary information to characterize the regional framework and to allow development of a numerical model, what other studies will be going on in parallel to provide the necessary information?

  • What information is available, or what analysis has been done, to estimate changes to the regional flow system due to the aggregate head-buildup and drawdown associated with the proposed projects?

No analysis has been conducted to date. Anecdotal data from existing FAS and ASR Wellfields (Town of Jupiter, Cocoa, Peace River) indicate that intense pressure build-up and drawdown has not occurred. We will document these and other data during the plan formulation process. Ultimately, the proposed regional modeling effort will best allow us to address this question.

  • How did selection of the proposed locations for exploratory wells, pilot ASR wells and monitor wells relate to locations that are likely to provide the necessary constraints for characterizing the regional framework?

The proposed sites for the 3 exploratory wells (i.e., at the confluence of the Caloosahatchee, Kissimmee, and St. Lucie Rivers with Lake Okeechobee) were selected for two primary reasons. First, these sites are known to possess a great amount of water availability. Of course, we know that Lake Okeechobee has available water, but conversations with Lake experts indicate that
