~. <br />~? <br />Table A-4, After airlifting well GB-5 on September 10, 1486, for approximately 70 <br />minutes, recovery of the water Ievel in the well was monitored fdr 75 minutes before <br />a water sample was bailed for quality analysis. Table A-5 presents aquifer-test <br />data for well GB-5. <br />Figure A-4 presents the recovery data for well GB-5. A straight line fit of <br />the recovery data yields a transmissivity value of 595 gal/day/ft for the HI aquifer <br />near well GB-5. This value is thought to be somewhat high. The recovery plot <br />indicates that the water levels will recover prior to a t/t' of one. The early <br />recovery of well GB-5 may have been caused by some recharge from a source other than <br />the HI aquifer which could result in a higher than actual transmissivity value. <br />Permeability was calculated to be 1.22 ft/day. <br />• A-2.4 GC-1 TEST <br />Well GC-1 was airlifted on September 18, 1985 to produce water from the H seam <br />aquifer. Recovery of the water level in well GC-1 was monitored after airlifting <br />had stopped. Table A-5 presents the aquifer-test data for well GC-1. <br />A plot of the recovery data for well GC-1 is presented in Figure A-5. The <br />recovery data gives a good straight line fit. Using the Theis Recovery method, a <br />value of 3.2 gal/day/ft for transmissivity of the H aquifer near well GC-1 is <br />obtained. Permeability of the aquifer here is thought to be 0.01 ft/day, <br />A-2.5 CC-2 TEST <br />We11 GC-2 was airlifted on September 22, 1985 and water level was monitored <br />• <br />A-s ~E1flSED FEB 13'87 <br />
