The soil samples were hand delivered <br />' under chain-of-custody procedures to GeoAnalytical Laboratories <br /> in Modesto, California, for analyses . <br /> I <br /> 3.0 OVER-EXCAVATION <br />' Following the collection of soil samples beneath the tanks, <br /> Pit 1 was over--excavated in an attempt to remove the observed <br />' petroleum stained soil (Figure 3, Appendix A, Over-Excavation - <br />' Pit 1) . Mary Maese of the San Joaquin County Environmental <br /> Health Department was on site to observe the over-excavation and <br />' direct soil sampling. Glen White of Condor monitored the over- <br /> excavation and collected soil samples as directed by the County <br /> representative. <br />' The sidewalls of the tank excavation1 Pit <br /> { ) were extended <br />' outward approximately 3 feet laterally and the floor was <br /> excavated to a depth of approximately 17 feet below the ground <br />' surface. A patch of grey petroleum stained soil remained on the <br />' north sidewall from the 6 foot depth to a depth of approximately <br /> 11 feet below the ground surface. No petroleum staining or odors <br />' were noted in the soil on the remaining sidewalls or floor of the <br /> excavation. Additional excavation to the north could not be <br />' conducted at that time due to the proximity of the concrete <br /> driveway and pump island. <br /> I <br /> CONDOR <br />
