<br />The late-time flow data shown in Figure A-15 gives a good straight line fit. <br />Analysis of the straight line fit yields a transmissivity value of 1500 gal/day/ft <br />for well CF-1 completed in the 20 mile sandstone. Discharge rates ranged from 13.41 <br />gallons per minute gpm) to 11.56 gpm throughout the 250 minutes the well was <br />allowed to flow. This would indicate, along with the high transmissivity value, <br />that the 20 mile sandstone near well GF-1 produces very well. Permeability of the <br />20 mile aquifer near well GF-1 was roughly 20 ft/day. <br />A-2.11 GF-2 TEST <br />Well GF-2 was pump tested on September 10, 1986. Water levels were monitored <br />while a discharge of .33 gpm was maintained for 3 hours. Table A-14 presents the <br />~ aquifer-test data collected during the pump test on well GF-2. <br />A straight line through the late-time data point and corresponding earlier <br />data that also aligns well yields a transmissivity of 3 gal/day/ft see Figure <br />A-16). This transmissivity value is thought to be representative of the U Complex <br />aquifer in which well GF-2 is completed. A permeability of 0.10 ft/day was <br />calculated using the 3 gal/day/ft transmissivity value. <br />A-2.12 GF-4 TEST <br />A single well pump test was conducted on well GF-4 on September 9, 1986. <br />Water-level data was collected during the early time of the test. A discharge rate <br />of 2.7 gpm was maintained, resulting in 45 feet of drawdown 16 minutes into the <br />test. Aquifer-test data collected during the pump test on well GF-4 is presented in <br />u <br />A-a (f~~lBSc® fEB 13'87 <br />
