I <br /> t <br />' Project No 58080-06-01C <br /> August 31, 1994 <br />' Soil Vanor Survey Results <br /> Soil vapor collection was unsuccessful at depths of 35 and 43 feet bgs in probe location SVS-1 <br />' due to low subsurface vapor flow rates In addition, refusal conditions were encountered at <br />' a depth of 43 feet in SVS-1 Due to the relatively low flow rates and refusal conditions <br /> encountered in SVS-1, subsequent soil vapor probes were driven to target depths between 8 <br />' and 28 feet bgs <br />' A total of 15 soil vapor samples were collected from probe locations SVS-1A through SVS-9 <br />' The soil vapor samples were analyzed for TPHg and BTEX The results of the laboratory <br /> tests indicated nondetectable concentrations of the target compounds for soil vapor samples <br /> wcollected from probe locations SVS-1A, SVS-3, SVS-4 and SVS-7 Relatively low TPI-Ig <br />' concentrations of 2 and 3 parts per million by volume (ppmv) were reported for soil vapor <br /> samples collected between depths of 10 and 17 feet bgs from probe locations SVS-2, SVS-5, <br />' SVS-6, SVS-8 and SVS-9 A TPH concentration of 36 ppmv was reported for a soil vapor <br />' sample collected at a depth of 23 feet bgs from probe location SVS-8 A summary of the soil <br /> vapor survey results and field log prepared by TEG are presented in Appendix D <br /> 1 <br /> - 24 - <br />
