• ~ A-2.25 J-1 TEST <br />Table A-28 presents data collected during the single well pump test conducted <br />on well J-1 on September 18, 1985. Water level and discharge rate were monitored <br />throughout the test. <br />Drawdown versus time on a semi-log plot for well J-1 is presenCed in Figure <br />A-32. Drawdowns have been corrected for aquifer thinning effects. Applying Jacob's <br />method to the straight line fit of the early data yields a transmissivity value of <br />1665 gal/day/ft for the alluvium near well J-1. Using this transmissivity, <br />permeability was calculated to be 7.4 ft/day. The value of transmissivity is <br />thought to be representative of the alluvium near well J-1. <br />A-2.26 COY TEST <br />• ~ A multi-well pump test using well COY as a pumping well and well COY-A as an <br />observation well was conducted September 25, 1985. Table A-29 presents the water <br />levels monitored throughout the 100 minutes of pumping. An aquifer thinning <br />correction was applied to the drawdowns for the alluvial aquifer near well COY. <br />Figure A-33 presents the drawdown data for well COY. Using a straight line <br />fit of the data on a semi-log plot, a transmissivity of 950 gal/day/ft is obtained. <br />Permeability was calculated to be 2.4 ft/day using the transmissivity of 950 <br />gal/day/ft. The values are thought to be lower than average transmitting properties <br />for the alluvium near the COY well. <br />Figure A-34 presents the semi-log plot of [he recovery data for alluvial well <br />COY. A straight line fit of the data yields a transmissivity value of 5000 <br />• <br />A-15 ~1~1a~~ F~k~ ~ j t1~ <br />
