ARCADIS GERAGHTY&MILLER <br /> 5. RESULTS <br />' 5.1 MONITORING WELL INSTALLATION <br /> Boring NP-1 was advanced, with soil samples taken, to a total depth of 119 feet bgs <br />' and is the deepest boring advanced to date within the Site property boundaries The well <br /> completion was planned and installed as a nested well completion Three 1-inch diameter, <br />' Schedule 40 PVC wells were completed in the boring NP-1-22 is a screened from 22 tome' <br /> feet bgs NP-1-65 is screened from 65 to 75 ft bgs NP-1-i 11 is screened from 111 to 116 ft <br /> bgs The well completion for NP-1 relative to the Site stratigraphy is illustrated in Figure 5-1 <br /> Boring NP-2 was advanced, with soil samples taken, to a total depth of 123 5 feet bgs <br /> and is the deepest boring advanced to date relevant to the Site NP-2 was advanced on the <br /> opposite side of California Street from the Site The well completion was planned and installed <br /> as a nested well completion Three 1-inch diameter, Schedule 40 PVC wells were completed <br />' in the bonng NP-2-22 is screened from 22 to 47 feet bgs NP-2-60 is screened from 60 to 70 <br /> feet bgs NP-2-116 is screened from 116 to 121 feet bgs The well completion for NP-2 <br />' relative to the Site stratigraphy is illustrated in Figure 5-1 <br /> Boring logs, well completion details, and diagrams for installed well nests NP-1 and <br /> NP-2 are shown m Appendix C <br />' <br /> 5.2 SITE SUBSURFACE STRATIGRAPHY <br />' The USCS textural classification of soils encountered m soil borings NP-1 and NP-2 is <br /> illustrated in Figure 5-1, along with the nested well completions Boring NP-1, terminated at <br /> 119 feet bgs, is the deepest boring advanced within Site property boundaries to date <br /> Previously, the deepest boring on Site (U-2) had been advanced to 60 feet bgs The soils <br /> encountered m boring NP-1 between ground surface and 60 feet bgs was generally consistent <br /> 21 <br />
