31 August 2000 <br /> AGE Project No 96-0232 <br /> Page 11 of 25 <br /> Draw-down versus tune for well MW-1 was plotted on semi-loganthlmc scale graph paper for stages <br /> 1, 2 and 3 of the pump test, utilizing the Jacob straight-line method,the transmissivity for each stage <br /> of the pump test was determined (Appendix A) Ground water levels in wells MW-2, MW-4 and <br /> MW-6A did not appear to be influenced during the pump test <br /> During the first stage of the pump test(pump rate at 4 3 GPM), ground water was drawn below the <br /> pressure transducer in MW-1 after 19 minutes of pumpmg operation No measurable draw-down was <br /> observed from wells MW-2 (Iocated 120 feet towards the east), MW-4 (located 95 feet towards the <br /> north) or MW-6A (located 75 feet towards the south) during the first stage of the pump test A <br /> transmissivity value from well MW-1 was calculated at 135 gal/day-ft <br /> During the second stage of the pump test (pump rate at 3 5 GPM), the greatest ground water draw- <br /> down was observed at 6 91 feet after 11 minutes of pumping operation Due to an equipment <br /> malfunction, the test was terminated after 11 minutes of operation No measurable draw-down was <br /> observed from wells MW-2, MW-4 or MW-6A during the second stage of the pump test A <br /> transmissivity value from well MW-1 was calculated at 349 gal/day-ft <br /> During the third stage of the pump test (pump rate at 3 GPM), the greatest ground water draw-down <br /> was observed at 4 42 feet after 125 minutes of pumping operation Due to an equipment malfunction, <br /> the test was terminated after 125 minutes of operation No measurable draw-down was observed <br />' from wells MW-2, MW-4 or MW-6A during the third stage of the pump test A transmissivity value <br /> from well MW-1 was calculated at 932 gal/day-ft <br /> Pump test results are summarized in Table 1, pump <br /> test calculations, plots of draw-down vs time <br /> and copies of draw-down logs are contained in Appendix A <br />' 32 FIRST ZONE AQUIFER PUMP TESTS, 20 AND 24 JULY 2000 <br /> I The first stage of constant rate ground water pump testing consisted of extracting ground water <br /> utilizing a Grundfos Redi-Flo pump from EW-2 in the First Zone Aquifer at a rate of 4 0 GPM, the <br /> second stage consisted of extracting ground water at a rate of 6 6 GPM, the third stage consisted of <br />' extracting ground water at a rate of 10 GPM <br /> The first stage pump test (4 GPM) consisted of extracting ground water from well EW-2 utilizing <br />' a 2-inch diameter submersible Grundfos Redi-flo pump and was terminated after 90-minutes of <br /> pumping when the pump malfunctioned by over-heating The second stage pump test(6 6 GPM)was <br /> initiated by extracting ground water from well EW-2 for 600 minutes utilizing a 4-inch diameter <br />' submersible Grundfos Redl-flo pump, the test was terminated after 600 minutes of ground water <br /> extraction because the 5,900-gallon Baker tank was at full capacity The third stage pump test (10 <br />' GPM) consisted of extracting ground water from well EW-2 utilizing the 4-inch diameter <br /> Advanced GeoEnvlronmental,Inc <br /> 1 <br />
