Geraghty & Miller, Inc. , _ M _. I. R. County Comm. - 4 - 12 Dec 79 will be conducted in the region above the Floridan Aquifer to detect the presence or absence of this aquifer. Geraghty & Miller, Inc., has equipment to prepare these logs and will provide the services. In the Floridan Aquifer, more extensive logging is necessary and the drilling contractor will provide geophysical services. Among the logs that will be required in the Floridan Aquifer are electric, gamma, temperature, caliper, flow meter, and fluid conductivity logs. The hydro - geologist will coordinate between Geraghty & Miller, the Joint Venture, and the drilling contractor so that logging and any other special testing procedures are completed on schedule. Upon the completion of drilling, Geraghty & Miller, Inc., will assist the contractor in the performance of pumping tests. At least one controlled pumping test of approximately 72 hours' duration will be conducted on the test -production well. This test will be designed so that the hydrologic characteristics of the Floridan Aquifer will be established. Factors to be evaluated will be transmissivity, storage, vertical leakance, and the potential for upconing. Knowledge of these charac- teristics will serve as the basis for evaluating the impacts of the proposed diversion aid determining optimum well yields. Additional capacity tests and flow tests may be performed on the test -production well and observation well. Geraghty & Miller personnel will direct the contractor in the test proce- dures, collect water -level and water -quality data during the tests, and determine the testing periods. Water samples collec- ted from the monitoring tube and from the pumped discharge dur- ing the test will be forwarded to a chemical laboratory for analysis. Task 4 -- Analysis of Data and Preparation of Reports Indian River County will receive monthly progress reports dur- ing this program. Upon the completion of testing, Geraghty & Miller, Inc., will analyze the data collected during the well inventory, and the drilling and testing program, and prepare a final report of the investigation. The report will describe the steps taken during the drilling and testing program, and present the pertinent data collected during the well inventory. Geologic and hydrologic conditions in the taxing district and surrounding area will be described. Based on the program results, recommendations of well -field design, well construction, DEC 1.9 1979 800x 2- PACE37
