Geosyntec <br /> CO1V,t 11', <br /> The sequence of swabbing/bailing, airlifting, and pumping will be repeated until the field staff, <br /> under the supervision of a California Licensed Professional Geologist, determines the well has <br /> been adequately developed based on stabilization of the specific capacity and groundwater <br /> quality parameters. <br /> Well development water will be stored in a series of water tanks adjacent to the extraction wells. <br /> The water will be transported from the water tanks to the on-site treatment system via vacuum <br /> truck for treatment and disposal. <br /> 5.2.2 Hydraulic Testing and Analysis <br /> Following development, step-drawdown tests will be conducted at EW-18A, EW-1813, and <br /> EW-19. During each test, water levels will be monitored with transducers in the extraction well <br /> and in monitoring wells within approximately 2,000 feet of the extraction well. The observations <br /> of hydraulic response will be used to estimate the extraction well efficiency and yield, including <br /> specific capacity, to estimate the aquifer properties and capture, and to evaluate the extraction <br /> flowrates for operation of EW-18A, EW-1813, and EW-19. <br /> 5.2.2.1 Transducer Deployment and Retrieval <br /> Pressure transducers will be installed in observation points as described below in Table 2 and <br /> shown in Figure 2. <br /> Table 2: Proposed Observation Wells <br /> Test Well Observation Point Monitoring Well Estimated Distance <br /> (screen interval) Transducers Screen Interval from Extraction <br /> Well**(feet) <br /> PW12-078 65-72 11440 <br /> PW16-083 75-80 1,730 <br /> PW21-087 79-84 1,620 <br /> EW-18A PW26-086 69-79 1,230 <br /> (70-95 feet bgs) <br /> PW30-080 70-90 120 <br /> PW31-080 70-90 1,130 <br /> PW33-085 70-85 1,740 <br /> PWO1-129 121-126 440 <br /> PW 12-139 131-136 1,440 <br /> PW 16-146 138-143 1,730 <br /> PW21-155 147-152 1,620 <br /> PW26-154 137-147 1,230 <br /> EW-18B PW30-130 120-140 120 <br /> (110-185 feet bgs) PW30-180 170-190 120 <br /> PW31-130 120-140 1,130 <br /> PW31-180 170-190 11130 <br /> PW33-125 115-125 1,740 <br /> PW 34-160 140-160 1,590 <br /> P W 35-140 120-140 1,100 <br /> Extraction Well Installation Work Plan 7 November 30,2018 <br />
