~• <br />A-1.0 INTRODUCTION <br />Operational and pre-mining wells were pump tested during monitoring or after <br />well installation by Hydro-Engineering (HYDRO). Water quality samples were <br />collected from each well. Single well pumping tests were conducted on moat wells. <br />Wells GC-3, GP-3, GP-6 and COY had multi-well pumping tests conducted using wells <br />GC-3A, GC-36, GP-3A, GP-6A, COY-A, and COY-B as observation wells, respectively. <br />Each pump test will be discussed in the fallowing sections. Aquifer-test data <br />and plots of the drawdown, recovery or flow data are included for the respective <br />wells that were analyzed. Table 2.7-21b will present the summary of aquifer <br />properties .+ Section A-3.0 of this appendix presents the aquifer test theory used to <br />a analyze these tests <br />A-2.0 GA-2 TEST <br />A single well recovery test was conducted on well GA-2 September 17, 1985. <br />Well GA-2 was airlifted for approximately 100 minutes. The recovery of the well was <br />monitored to yield the aquifer-test data presented in Table A-1. The Theis Recovery <br />Method was applied [o the plot of residual drawdown versus time since pumping <br />started divided by time since pumping stopped (t/t') to obtain a transmissivity of <br />30 gal/day/ft in Figure A-1. The Theis Recovery method is discussed in Section <br />A-3.0, Part A of Appendix V, Aquifer-Test Theory. <br />The plot of recovery data for well GA-2 shows that recovery would not be <br />complete at t/t' of one as theory indicated. This causes the resulting <br />• <br />A-1 REVISED FEB 13 '87 <br />
