I i pump in RW1A The water will be pumped through carbon to the sanitary sewer under vanance from the Stockton sewer district This test will be carred out for a period of eight hours Dunng the test, the pump rate will be increased an steps, starting at one gallon per minute As the drawdown in the well reaches equilibrium, the pump rate will be increased an one gallon per minute increments Down hole pressure transducers will be used to collect drawdown information from MW6A, N4W6B, RW 1 A, and RW 1B The top of water will be sounded an the other wells periodically with the depth to water meter and the fame and measurement will be recorded The results of the test will be evaluated by developing both distance drawdown and drawdown over time graphs for the wells STEP DRAWDOWN TEST RWO1E In order to get some idea of the practicality of de-watering the B-Zone a Step Drawdown test will be performed in RW1B The test will be performed by placing a vanable speed Grundfos pump in RW1B The water will be pumped through carbon to the sanitary sewer under variance from the Stockton sewer district This test will be carried out for a penod of eight hours During the test, the pump rate will be increased in steps, starting at one gallon per minute As the drawdown in the well reaches equnlabnum,the pump rate will be increased in one gallon per minute increments Down hole pressure transducers will be used to collect drawdown information from MW6A, MW6B, RW 1 A, and RW 1 B Depth to water an the other surrounding wells wall be measured periodically with the depth to water meter and recorded The results of the test will be evaluated by developing both distance drawdown and drawdown over time graphs for the wells 24 HOUR CONSTANT RATE PUMP TEST MW6A In order to determine the aquifer properties of the upper sand (A Zone) a constant rate pump test will be performed from MW6A The pump will be placed in MW6A and water will be pumped from the well at a rate that will not convert the well from confined to unconfined conditions Down hole pressure transducers will be used to collect drawdown information from MW6A, MW6B, RW 1 A, and RW 1 B Depth to water an the other surrounding wells will be measured periodically with the depth to water meter and recorded The results of the test will be evaluated by developing both distance drawdown and drawdown over time graphs for the wells Of particular interest in thus test will be the timing of the observable drawdown to MW6B, which will be indicative of the leakage between the two sands 24 HOUR CONSTANT RATE PUMP TEST MW6B • In order to determine the aquifer properties of the B-Zone sand a constant rate pump test will be performed from MW6B The pump will be placed in MW6B and water will be pumped from the well at five gallons per minute 3 Rev Pump Test Plan-Appendix A, 1110102
