discharge test produced only 2 feet of drawdown The 2 gpm flow rate produced more than 8 feet of <br /> drawdown, which dewatered the well A flow rate of 1 5 gpm was selected for the constant-discharge <br /> test <br /> Constant-Discharge Test Procedures <br /> The constant-discharge tests were performed in two on-site wells RW-1A and MW-2 The <br /> constant-discharge test for Well RW-IA was performed on October 29, 1997 and the constant- <br /> discharge test for MW-2 was performed on October 30, 1997 <br /> The procedures for the constant-discharge test were the same as the step-discharge test procedures <br /> except that the flow rate remained constant for the entire test The duration of each constant- <br /> discharge tests was 360 minutes (6 hours) Transducers and dataloggers were used to collect ground <br /> water level measurements in the pumping wells and also in three nearby ground water monitoring <br /> wells during each test Manual water level measurements were also collected in all site monitoring <br /> wells during the test with an electronic water level indicator <br /> After pumping for 360 minutes the pump was shut off and the dataloggers were reset to monitor the <br /> water level change in the pumping well as the well recovered to static water level This recovery data <br /> was used to calculate the transmissivity and hydraulic conductivity of the aquifer in the vicinity of <br /> each well <br /> Constant-Discharge Test Findings <br /> Well RW-IA Well RW-IA was pumped at a flow rate of 15 gpm for 360 minutes during the <br /> constant-discharge test This flow rate produced a drawdown in RW-IA of approximately 9 feet <br /> below static water level after 15 minutes of pumping Drawdown gradually increased during the test <br /> and reached a maximum of approximately 10 5 feet below static water level at 360 minutes of <br /> pumping <br /> During the constant-discharge test, drawdown due to pumping in RWAA was noted in monitoring <br /> wells MW-2, MW-3, MW-4, MW-5, and MW-8 Negligible water level change was observed in Wells <br /> MW-6 and MW-7 Wells MW-9 through MW-13 had not been installed yet and therefore were not <br /> monitored during aquifer testing <br /> The greatest drawdown was observed in MW-5, which is the closest well to RW-IA MW-5 is located <br /> 27 feet from RW-IA and had a maximum drawdown during the constant-discharge test of 0 80 feet <br /> Well MW-3 had a maximum drawdown of 0 6 feet and is located 70 feet from RW-IA Well MW-8, <br /> located 97 feet from RW-IA had a maximum drawdown of 0 35 feet Well MW-4 had a maximum <br /> 240-0783 8 <br />
