24 HOUR CONSTANT RATE PUMP TEST RWIB <br /> In order to determine the aquifer properties of the lower sand (B Zone) a constant rate pump test <br /> will be performed from RW I B The pump will be placed in RW I B and water will be pumped for <br /> 24 hours at a rate that will not convert the well from confined to unconfined conditions as prelected <br /> from the earlier step drawdown test <br /> Downhole pressure transducers will be used to collect drawdown information from PZ I A, PZ I B, <br /> PZ2A, PZ2B MW i, RW 1 A, and RW 1 B Depth to water in the other surrounding wells will be <br /> measured periodically with the depth to water meter and recorded The results of the test will be <br /> evaluated by developing both distance drawdown and drawdown over time graphs for the wells <br /> Of particular interest in this test will be the early data, which should show the arrival of the <br /> drawdown cone at each of the wells Also of interest will be the drawdown patterns in the upper <br /> zone These patterns should, if the clay forms a significant aquitard, produce a drawdown cone <br /> centered on MW 1 as the groundwater flows between the two sands <br /> TEST TO DETERMINE TIGHTNESS OF SEALS MW6A, MW6B, <br /> In order to determine if there is commumcation between the two groundwater zones due to the <br /> presence of MW6B, a short test will be performed in MW6A The pump will be placed in MW6A <br /> and water will be pumped from the well at the pump's maximum capacity <br /> Downhole pressure transducers will be used to collect drawdown information from MW6A, <br /> andMW6B <br /> Of particular interest in this test vAll be the timing of the arrival of observable drawdown in <br /> MW6B, which will be indicative of the leakage between the two sands <br /> TEST TO DETERMINE TIGHTNESS OF SEALS MW7A, MW7B <br /> In order to detcnnine of there is communication between the two groundwater zones due to the <br /> presence of MW7B, a short test will be performed in MW7A The pump will be placed in MW&A <br /> and water will be pumped from the well at the pump's maximum capacity <br /> Downhole pressure transducers will be used to collect drawdown information from MW7A, <br /> andM W 7B <br /> Of particular interest in this test will be the timing of the arrival of observable drawdown in <br /> MW7B, which will be indicative of the Ieakage between the two sands <br /> 4 <br /> Rev Pump Test Plan- 10/11/02 <br />
