' Stockton Plating Inc. <br /> Soil & Groundwater Investigation <br /> . April 19, 1996 <br /> Page - 13 - <br />' collected from SPT on March 2, 1994 . The direction of the <br /> groundwater gradient is shown in Figure 8 of this report. <br /> I <br />' 7.0 SUMMARY, CONCLUSIONS AND RECOMMENDATIONS <br /> 7.1 Investigation Summary <br />' Laboratory analyses of the soil samples collected from MW3 <br /> indicate low levels of gasoline contamination at depths of 20, 30 <br />' and 45 feet below the ground surface. No TEPH, TPH-G or BTEX <br />' were detected at or above the reported laboratory detection <br /> limits in the soil samples analyzed from MW1 or MW2 . <br /> During the drilling of the monitor wells, a distinctive <br /> olive-brown to grey-green discoloration in the soil was <br /> encountered at a depth of approximately 25 feet and extending to <br />' the bottom of each borehole. In MW3, the odor of gasoline was <br />' encountered at a depth of approximately 20 feet and septic- <br /> petroleum odors were present from approximately 25 feet to the <br />' bottom of the borehole. Strong septic odors were encountered in <br /> the soils from MW1 and MW2 at a depth of 40 feet to the bottom of <br />' each borehole. <br /> I <br /> Organic vapors were detected in soil samples collected from <br />' MW1, MW2, and MW3 during field screening using a PID (see <br /> Geological Logs, Appendix A) . The PID measurements for soil <br /> samples collected from MW1 and MW2 revealed no organic vapors in <br /> �� CONDOR <br />
