i~ <br />yield were calculated to be 15.8 ft/day and .02, respectively. <br />Using the Theis equation with [he log-log plot of the drawdown data in Figure <br />A-11, a transmissivity of 7100 gal/day/ft was obtained. Permeability and specific <br />yield were calculated to be 14.6 ft/day and .004, respectively. The transmissivity <br />found using Theis' equation agrees well with that found with Jacob's method. <br />A transmissivity and permeability of 5000 gal/day/ft and 20 ft/day, <br />i <br />• <br />respectively, are thought to be most representative of the Flume alluvial aquifer <br />near well GC-3. A specific yield of 0.05 also is thought to be representative of <br />the aquifer at this site. <br />A-2.7 GD-2 TEST <br />Well GD-2 is a flowing well completed in the R seam aquifer. A constant head <br />test on well GD-2 was conducted September 10, 1986. The pressure head of the well <br />was measured before initiating discharge. The discharge rate was then measured <br />throughout the test. Aquifer-test data for well GD-2 is presented in Table A-10. <br />A straight line fit of the data in Figure A-12 yields a transmissivity value <br /> <br />of 2240 gal/day/ft for well GD-2. Section A-3 .0, Part A of Appendix V explains the <br />Constant Head theory for aquifer tests used to analyze the data for well GD-2. <br />Permeability was not calculated because the thickness of the aquifer was not known. <br />Well GD-2 is a good producer and yields a high transmissivity value thought to be <br />representative of the R aquifer just down-dip of the QR mine area. <br />A-e REVISED FER 13 '87 <br />
