water level in the pumping well (EW-1) and observation well MW-5 were monitored with 10-PSI ' transducers and monitoring well P-1 was monitored with a 25-PSI transducer connected to the same data logger Observation wells P-3 and P-5 were monitored using 10-PSI transducers and ' monitoring well P-2 was monitored with a 15-PSI transducer connected to the same data logger ' A pedestnan tripped over the wire from observation well P-2 early in the test breaking one of the ' wires in the cable The P-2 transducer signal was lost The change m impedance resulting from the broken wire also affected the data from the other two transducers connected to this data ' logger The overlying water column pressure recorded by the transducer in the pumping well was elevated by the downward thrust on the water flowing toward the pump, resulting in a relative elevation of the water level recorded compared to the hand measured depths to water The transducer in observation well MW-5 recorded the combined pressure of the submersion in a two phase liquid (water overlain by a floating hydrocarbon layer) Since most of the useable data was obscured or lost, all of the transducer collected data was refected in favor of the manually collected data 20 STEP DRAWDOWN TEST A four step, step drawdown test was performed on August 17, 2000 The four steps were conducted at mean flow rates as maintained by DOLE' Flow Regulators of the indicated nominal flow rates The following table lists the nominal flow rate, the mean flow rate, the end of step drawdown, and the duration for each step of the step drawdown test Where the sum of two nominal flow rates are indicated, two DOLE valves were in use IStep Nominal Mean Drawdown Step Flow Rate Flow Rate (Ft } Duration (GPM) (GPM) (minutes) 1 05 049 048 30 2 10 1 02 1 17 35 3 05 + 10 144 245 50 4 1 5 1 73 321 45 H2 0 GE 0 L A GROUND WATER CONSULTANCY
