1 ' Libbey Owens Ford Co. Site Investigation August 23, 1996 Page-2- Approximately 15 cubic yards of soil were excavated during the investigation (Figure 3, ' Appendix A). Condor screened the excavated soil using an organic vapor analyzer-(photo ionization detector - PID). PID readings ranged from 5 to 80 parts per million (ppm). The soil was jogged ' according to the Unified Soil Classification System. From the ground surface to a depth of approximately 8 feet below the ground surface (bgs), the soil type was silty, fine grained sand. From ' 8 feet bgs to 'approximately 12 feet bgs the soil was well sorted, fine to very fine grained sand. The. excavation was terminated at 13 feet bgs. .All soil excavated during the fieldwork had a strong diesel odor. The excavated soil was placed in steel bins lined with plastic sheeting. The excavated soil was ' subsequently transported to Forward Landfill of Manteca, California, for disposal. ' 2.2 Sampling ' Soil samples were collected from the sidewalls of the excavation at 5 feet, 8 feet and 11.5 feet bgs for chemical analyses. Duplicate samples were collected at 8 feet and 11.5 feet for potential geotechnical testing. The soil samples were collected using a hand held, rod mounted, soil sampler fitted with a clean brass liner. Each soil sample was retained, undisturbed, in the brass liners. The liners were sealed at the ends with Teflon tape, capped, wrapped with duct tape, and labeled. The ' samples were placed in a cooler chilled with ice and delivered within 24 hours of collection, under chain-of-custody procedures, to GeoAnalyticai Laboratories in Modesto, California. The duplicate ' samples collected at 8 feet and 11.5 feet bgs are retained at Condor for geotechnical testing, if needed. ' Following the soil sampling, diesel product slowly entered the bottom of the excavation at approximately 12 feet bgs. A bailer sample was collected .for field inspection. At least I foot of idiesel product (dyed red) was observed at the bottom of the excavation. No groundwater interface was noted. Upon completion of the soil.removal and sampling, the excavation was left open and surrounded with barricades and safety tape. On July 25, 1996, a Condor representative collected a diesel product sample from the excavation for water content analyses. The product surface was located at a depth of approximately 9 ' feet bgs. The product thickness could not be determined since no groundwater interface was noted. Based on the field observations, it appeared that at least 2 feet of diesel product was present at the ' bottom of the excavation. A clean, disposable, bailer was lowered into the excavation and a product CONDOR
