4.0 SCOPE OF WORK <br /> We propose to conduct the simulated test by pumping GT-10 for up to four hours. A <br /> submersible variable-flow groundwater pump will be lowered into the well, and an in-line <br /> flow meter will be used to set the pumping rate at 3 gpm. The extracted water will be <br /> pumped into a temporary holding tank for later disposal.will be performed. <br /> Although the model predicts that no response would be felt in the Riverbank Aquifer, <br /> transducers will be lowered into GT-1, GT-5, and GT-6 as well as into GT-10. Both GT-5 <br /> and GT-6 are screened from 50-75 feet, and may therefore feel some effect from the <br /> pumping. The transducers will be connected to a datalogger for automatic recording of the <br /> drawdown. <br /> Based on the 3 gpm pumping rate and 4-hour test duration, we estimate that approximately <br /> 750 gallons of water will be extracted. This water will be stored in a 1,000-gallon Baker <br /> tank for later disposal. <br /> The drawdown data will be graphed against time using standard methods to determine the <br /> coefficient of transmissivity(T),hydraulic conductivity(K),and coefficient of storage(S). <br /> These data will then be used to revise the present geologic model and perform <br /> VisualModflow® simulations of potential remedial designs to design a cost-effective <br /> groundwater pump-and-treat system. After the simulations have been completed, <br /> Upgradient will prepare a report and corrective action plan. <br />
