foreman, was used to confirm the locations of the former tanks and pipeline prior to drilling. As agreed to by the SJCPHS, soil samples for analysis of VOCs were collected in the native material beneath the former tank and pipeline excavations at the depths presented below. Boring CE-1 Sample collected from 17 to 17.5 feet below ground surface (bgs) Boring CE-2 Sample collected from 20 to 20.5 feet bgs Boring CE-3 Sample collected from 3.5 to 4 feet bgs Boring CE-4 Sample collected from 18 to 18.5 feet bgs (Note: The sample depths for borings CE-3 and CE-4 were slightly modified from those presented in the June 23, 1995 workplan because of inadequate sample recovery. The changes in sample depths were approved by Mr. Sasson at the time of drilling.) Deeper soil samples from borings CE-1, CE-2, and CE-4 were also collected and retained in case VOCs were reported in the shallower samples itemized above. Because VOCs were not detected in the shallower samples, analysis of the deeper samples was not deemed necessary (see discussion below). Each soil boring was drilled using 6-inch-diameter hollow-stem augers. Soil samples for chemical analysis were collected using a California modified split-spoon sampler fitted with 2- inch-diameter by 6-inch-long brass or stainless steel tubes. These soil samples were retained in the sample tubes which were capped, labeled, sealed in plastic bags, placed in a cooler taw with blue ice, and taken under chain-of-custody to a State-accredited laboratory for analysis of VOCs, including acetone, by USEPA Method 8240. Soil samples for stratigraphic logging purposes were collected at approximately 5-foot intervals, or closer intervals, using standard penetration test and California modified split-spoon samplers. The soil core not retained for chemical analysis was (1) extruded, (2) logged by a California Registered Geologist in accordance with the Unified Soils Classification System, and (3) field screened for the presence of VOCs using a photo-ionization detector (PID). Borings CE-1 , CE-2, and CE-4 were grouted closed upon completion. Boring CE-3 was backfilled with the soil generated from that borehole. All drilling and sampling equipment was steam-cleaned before use to avoid potential cross-contamination. The drill cuttings and liquid produced during this task were containerized, labeled, and stored on site for future disposal pending receipt of the laboratory results. The soil cuttings have since been disposed of at Forward Landfill, along with the excavation spoils. ` The boring logs for CE-1 through CE-4 are included in Appendix A. The certified analytical reports (CARs) and chain-of-custody documentation are included in Appendix B. Table 1 summarizes the analytical results. r CYPRESS Universal-Rundle Corporation Page 4 v
