surface to the final depth of 190 ft bgs was characterized as unconsolidated fine to medium sand, silt, and sand/silt/clay mixtures. The lithologic log of the exploratory ' boring for well MW-449D is included in Appendix B. No lithologic log was recorded for the boring drilled for well MW-449S because the lithology did not markedly vary from the lithology characterized at the MW-449D boring ' approximately 10 feet away. 5.2 Boring for Well MW-450D ' The boring for well MW-450D was drilled on June 25, 2012. The diameter of the borehole was 10-7/8 inches. The lithology encountered from ground surface to the ' final depth of 192 ft bgs was characterized as unconsolidated fine to medium sand, silt, and sand/silt/clay mixtures. The lithologic log of the exploratory boring for well MW-450D is included in Appendix B. No lithologic log was recorded for the boring drilled for well MW-450S because the lithology did not markedly vary from the lithology characterized at the MW-450D boring approximately 10 feet away. 6.0 Geophysical Logs Welenco (California Contractor's License 722373) of Bakersfield, California was retained to run electrical geophysical logs in the boreholes drilled for wells MW-449D and MW-450D. Each electrical geophysical log included 16-inch normal and 64-inch normal electrical resistivity(ohm-meters), spontaneous potential (millivolts), single-point resistance (ohms), and focused guard (ohm-meters) logs. Natural gamma ray(api) and ' temperature(°F) logs were also conducted in each borehole. Prior to running the geophysical logs, the drilling mud in each borehole was thinned by circulating potable water through the drill pipe and into each borehole. Copies of the electrical geophysical logs are included in Appendix C. 61 MW-449D Exploratory Boring ' The electrical geophysical log was used in conjunction with the lithologic log of the MW-449D exploratory boring to identify the permeable zones of the intermediate zone and to design the screen intervals for wells MW-449S and MW-449D. The 16- inch normal, 64-inch normal, focused guard and single-point resistivity logs indicated lenses of fine to medium sand interbedded with sandy silt and clay. The thicknesses of the fine to medium sand lenses in the intermediate zone ranged from ' approximately 4 feet to 8 feet. The fine to medium sand characterized from 130 to 150 ft bgs in the lithologic log ' corresponded with a peak resistivity of 36 ohm-meters measured on the focused guard log at 143 ft bgs (Figure 3). The screen interval for well MW-449S was designed from 139 to 154 ft bgs to include the sand lenses in that interval. The fine to medium sand characterized at 170 ft bgs in the lithologic log corresponded with the peak resistivity of 77 ohm-meters measured on the focused ' guard log at 175 ft bgs. The screen interval for well MW-449D was designed from 165 to 180 ft bgs to include the sand lenses characterized in that interval.
