from 18 to 19.5 feet b s, the approximate depth of first encountered ground water. <br /> Appendix B contains the field borehole log for each soil boring. <br /> The soil cores and cuttings from each borehole were logged by an on-site geologist in <br /> accordance with the procedures of the American Society for Testing and Materials D 2488. <br /> In addition, approximately 50 grams of soil were collected from each sampling interval, <br /> L <br /> placed in a resealable plastic bag, and screened in the field for volatile organic compounds <br /> using a PID. PID readings are recorded on the boring logs. <br /> No visual soil staining or PID readings above background were noted at any of the borings. <br /> 3.2. Soil Sample Collection and Analysis <br /> Soil samples for potential laboratory analysis were collected from each soil boring using a <br /> brass-sleeve-lined, California-modified, split-spoon sampler; at approximate 5-foot intervals <br /> beginning at 2 to 5 feet bgs and extending to the total borehole depth. Following sample <br /> collection, the brass-sleeve containing the soil sample for laboratory analysis was <br /> immediately withdrawn from the sampler and sealed with Teflon® sheets and tight-fitting, <br /> [� plastic end caps. The soil samples were then labeled with a unique sample number, date, <br /> ir time of collection, initials of collector, and Terranext project number. Each soil sample was <br /> then placed in an insulated chest containing ice and delivered (along with chain-of-custody <br /> documentation) to Quanterra Environmental Services (Quanterra), located in West <br /> Sacramento, California for analysis. <br /> Select soil samples were analyzed for TPH-D, TPH-G, benzene, toluene, ethylbenzene and <br /> xylenes (BTEX), phenols and 17 California Assessment Manual (CAM) metals. <br /> Additionally, selected samples were submitted to the laboratory and placed on "hold" for <br /> 809-001.rpt./04-18-97/u/keydata/reports 6 <br /> TerraNext <br /> h <br />
