46, <br /> t <br /> Two soil samples were collected from each boring at shallow depths of-61.to 9 feet bgs, and deeper <br /> depths of 21.5 to 26.5 feet bgs. Soil samples were submitted to Argon Mobile Labs in Ceres, <br /> t <br /> -t California (Certification No. 1873) using chain of custody documentation. The samples were <br /> analyzed for total petroleum hydrocarbons.as gasoline (TPHg) and benzene, toluene, ethylbenzene <br /> and xylenes (BTEX) by EPA methods 8,015.(modified) and 8020, respectively. Analytical results <br /> for soil are contained in Table 1. <br /> Monitoring Well Construction <br /> On July 18, 1995, the three soil borings (B 1, `B2 and 133) "were completed as groundwater <br /> monitoring wells MW-1, MW-2, MW-3, respectively (Figure 2). Work was performed by <br /> Spectrum Exploration, Inc. Well construction materials consisted of 2-inch inside diameter PVC <br /> well screen and casing. A 0.010-inch well screen,slot and #2/12 mesh sand pack were used. Well <br /> MWI was screened from 5 to 22 feet bgs. Wells MW2 and MW3 were screened from 5 to 25 <br /> h`J feet bgs.• A bentonite clay plug and neat cement were-used to seal the wells"in accordance with <br /> California Well Standards (December 1981). To protect the integrity of the wells, a water-tight <br /> U <br /> well plug and locking utility box was installed on each well, and a water-tight wellhead was <br /> concreted over each well. Construction details are shown on the well logs provided in Appendix <br /> Groundwater Monitoring and Sampling <br /> On Jul 21 1995 the relative elevation of the tops of the wellheads for wells MW-1 MW-2 and <br /> July P _ <br /> MW-3 were surveyed, and the depths to water in the wells were measured-to evaluate the <br /> 1 - <br /> _ N:195122\PAR.doc <br /> 3 SKTH <br />
