Hydrogeologic Investigation Of The Floridan Aquifer System PDF Download

The Kissimmee Basin Water Supply Plan (KBWSP, 2000) was the first look at the long-term water use conditions for areas in the South Florida Water Management District (SFWMD) located north of Lake Okeechobee. The findings of the KBWSP suggest that the groundwater supplies in Osceola County area may not be sufficient to meet the 2020 (1-in-10 drought year) water supply needs. The continued use of the upper Floridan Aquifer System (FAS) may affect wetlands, reduce spring flow, and possibly be a factor in the formation of sinkholes in this area. However, these conclusions are predicated on a limited amount of geologic and hydrologic information in this region. In particular, information regarding the lower Floridan aquifer is very limited. The highest ranked recommendation of the KBWSP is to gather additional hydrogeologic information on the FAS to better resolve the uncertainty of future water use affects. These wells will supply information needed to characterize the water supply potential of the FAS and for use in development of a ground water flow model, which will support future planning and regulatory decisions. This report documents the results of three Floridan aquifer wells constructed and tested under the direction of the SFWMD. The Intercession City site was selected to augment existing hydrogeologic data and to provide broad, spatial coverage within the Kissimmee Basin planning area.
