Description
This study will evaluate the potential for ASR operation in the Avon Park Formation, which is not the injection zone
typically used for ASR in the southern and central areas of the District. Investigators from the University of South
Florida Geology Department will conduct a detailed mineralogical and chemical investigation of the Avon Park
Formation that will culminate in an ASR operation model. Compounds that are regulated by primary and secondary
drinking water standards will be considered, with an initial focus on arsenic and its identified source, pyrite. Major
tasks of the study will include: descriptions of existing cores; sample collection; chemical analysis and interpretation of
cores; collection and analysis of Avon Park Formation groundwater; and modeling a range of ASR scenarios using the
collected data.
Benefits
Water supply continues to be a critical issue in the SWUCA, and this study compliments the District's water supply
planning efforts. This project will enable the District and local governments to make knowledgeable decisions about
future investment in ASR.
Costs
Six Basin Boards have been asked to participate in funding this project at a level of $12,000 each in FY2007 and
$12,000 each in FY2008.
Additional Information
ASR is an important water supply option that is integral to water resources management in the SWUCA. Because of
the significant benefit to future water supply that ASR can provide, the District has funded several ASR projects and
investigative studies to further develop this technology. Over the past several years, there have been growing
concerns about the quality of water retrieved from the current injection zone, the Suwannee Limestone. Elevated
arsenic concentrations have been consistently discovered in injectate that is stored and recovered from the Suwannee
Limestone. The results of this study will be an important tool that can be used to evaluate future ASR development in
the SWUCA.
