G 4 I � 14 May 2003 AGE-NC Project No 01-0865 Page 2 of 5 disconnected,the power supply cord for the extraction pump Approximately 2,650 gallons of water were extracted from EW-2 during the eight-hour test - r 2 1 1 Pump Test Results ' During the variable rate pumping test (4 to 6 gpm), the maximum ground water drawn-down in extraction well EW-2 was observed to be 7 98 feet after 465 minutes of pumping operation utilizing ' water meter data Maximum draw-down was observed in the observation wells as follows • EW-2 (extraction well) at 7 98 feet after 465 minutes of pumping operation, ' • MW-2(located 15 feet toward the west-southwest)at 196 feet after 465 minutes of pumping operation I • MW-7(located 18 feet toward the west-southwest)at 0 43 feet after 465 minutes ofpumping ' operation • MW-1 (located 66 feet toward the east-southeast)at 0 23 feet after 450 minutes of pumping '. operation, • AS-1 (located 15 feet toward the south-southwest)at 0 21 feet after 465 minutes of pumping ' operation, • MW-3 (located 67 feet toward the southwest) at 0 11 feet after 450 minutes of pumping operation, and I _ • MW-5 (located 84 feet toward the east-northeast) at 0 05 feet after 465 minutes of pumping operation , The maximum ground water draw-downs in observation wells MW-1,MW-2 and MW-3 versus the ' distance ofthese wells from the extraction point were graphed on semi-logarithmic paper(Appendix B), these wells were screened at approximately the same depth as well EW-2'and 'were used to - calculate hydrologic properties Wells-,MW-5,,MW-7 and-AS-1 were screened-at different depths, ' and their hydrologic properties may be different A graph of draw-down versus,time for extraction well EW-2 and observation wells MW-1,MW-2 ' and MW-3 are included in Appendix C ' E 1 I !
