3 1 Flow Rate <br /> During the constant rate test the flow rate was controlled by the methods discussed in Section <br /> 1 1 The average flow rate during the 1,000 minutes of the test was 8 817 GPM <br /> 32 Drawdown Data <br /> Water level monitoring was conducted between about 15 00 on November 01, 2001 and 10 10 <br /> on November 02, 2001 The pumping well, EW-1, and five observation wells (MW-2, AS-1, <br /> MW-4, MW-3, and MW-6) experienced drawdown in response to the test All of the listed <br /> observation wells expenenced an interpretable response <br /> Semilogarithnuc (semi-log) and double loganthmsc (log-log) graphs of drawdown versus <br /> elapsed tune since the pump was started are presented in Figure Al through A6 in Attachment A <br /> for the extraction well(Figure Al) and the observation wells (Figure A2 MW-2, Figure A3, AS- <br /> 1, Figure A4, MW-4, Figure A5, MW-3, and Figure A6, MW-6) The drawdown data collected <br /> during the constant rate pump test and corresponding elapsed tune is included as Tables Al and <br /> A2 <br /> 40 CONSTANT RATE TEST INTERPRETATION <br /> 4 1 Saturated Thickness <br /> The first encountered water bearing formation beneath 574 West Grant Line Road exists in an <br /> unconfined condition The aquifer thickness is assumed to 12 58 feet, the saturated thickness at <br /> well EW-1 Phis aquifer thickness is assumed to apply at all five observation wells from which <br /> interpretable data was obtained The apparent thickness of the saturated materials varies from <br /> day to day depending on the depth to the top o1 the saturated materials <br /> H 2OGEOI.
