Adams dated September 18, 1992, regarding the request of the Department of Planning and Natural Resources (DPNR) assistance for the temporary shut-down of active supply wells in the Tutu area during the aquifer pumping tests. Geraghty & Miller has determined that the only supply wells that may influence the aquifer pumping tests are the Four Winds Plaza Wells (Four Winds I, Four Winds n, Four Winds IE). Geraghty & Miller has made arrangements with Four Winds Plaza to shut down their supply wells during the aquifer testing. It is our understanding that other supply wells that would potentially impact our pumping tests (i.e., the Tillett and Eglin Wells) are not currently active. Therefore, it will not be necessary for the DPNR to contact any supply well owners. In addition, the aquifer pumping test schedule (attached) has been revised which includes an extension of the November 2, 1992 pumping test from 24 hours to 72 hours, as required by the U.S. Environmental Protection Agency (USEPA).
