Fred Clark/Reynoso Concrete Construction Company Report -2- S-2, were collected from the stockpiled material at random locations (Figure 2) . The overburden material which. had been removed from the excavation was left on site adjacent to the excavation awaiting analytical results. Soil samples were collected in six-inch brass tubes. Both ends of the tubes were covered with aluminum foil, and capped with polyethylene caps. The samples were sealed in zip-lock bags and immediately placed in a cooler containing crushed ice. The samples were transported the same day under strict chain-of-custody to American Environmental Laboratory, a California Department of Health Services (DHS) certified laboratory. LABORATORY ANALYTICAL RESULTS Samples P-1, 2-E, 2-W, SP-1, and SP-2 were analyzed for total petroleum hydrocarbons as gasoline (TPH-G) , for benzene, toluene, ethylbenzene, and xylene (BTEX) by EPA methods 5030/Modified 8015, and 8020, for total lead, and for ethylene dibromide (EDB) . Samples P-1, SP-1 and SP-2 were also analyzed for total petroleum hydrocarbons as diesel (TPH-D) and total petroleum hydrocarbons as waste oil (TPH-WO) . Sample # 1 was analyzed for TPH-D and BTEX. Copies of the chain-of-custody forms and the analytical data sheets are included with this report. Table 1 shows the results of the laboratory analysis.
