| Purpose | The objective of this contract is to obtain HRMSRP and DC Resistivity profiles as applicable to the sites designated as Sentinel Lakes to characterize the subsurface of each water body. Of special concern is identifying discontinuities in the confining units between surface water and groundwater systems. | ||||||||
| Location | Central Florida Lakes | ||||||||
| Summary | CRP surveys were conducted in 8 lakes: Avalon, Cherry, Helen, Hiawassee, Johns, Louisa, Saunders and Sylvan. Land-based resistivity surveys were conducted in 3 lakes: Colby, Crooked, and Prevatt. | ||||||||
| Info derived | Resistivity techniques will be utilized to obtain information on geologic framework and composition in lakes identified in the project. | ||||||||
