excavations and from soil stockpiles in compliance with City of Lodi and Lodi Fire Department <br /> requirements. A total of seven soil samples were collected at the site;two from below the former gasoline <br /> L tank,two below the former diesel fuel tank,and three from the excavation soil stockpiles. A summary of <br /> the soil sampling program is presented in the following sections. <br /> 3.3.1 Former Underground Tanks <br /> Two soil samples (Tl-1@14'and Tl-2@14')were collected below the former underground diesel fuel tank <br /> and two soil samples(T2-1@14'and T2-2@14')were collected below the former underground gasoline tank. <br /> All four soil samples were collected in native soil at depths of approximately 14 feet below the ground <br /> surface (approximately two feet below the bottom of the former tanks). The location of each sample is <br /> shown in Figure 2. <br /> Each soil sample was collected using the backhoe bucket. Each soil sample was collected near the teeth of <br /> the backhoe bucket by driving a six-inch brass sample ring into native soil within the bucket. Each soil <br /> sample was properly sealed, labeled, and immediately placed in an ice-chest containing ice for transport. <br /> The soil samples were delivered under proper chain-of-custody to a certified independent analytical <br /> laboratory. <br /> During the underground storage tank closure soil sampling program, Blaes Environmental noted that the <br /> native soil in the excavation was clayey silty sand from the ground surface to a depth of approximately 14 <br /> feet below the ground surface. Groundwater was not encountered in the excavation at the time of the tank <br /> closure program. However,the soil was very moist from the recent heavy rain in the area. <br /> 3.3.2 Soil Stockpiles <br /> Two soil samples (SP-1 and SP-2) were collected from the soil stockpiles associated with the gasoline <br /> excavation. One soil sample(SP-3)was collected from the soil stockpile associated with the diesel fuel tank. <br /> Each soil sample was collected from a representative location within each stockpile. The soil samples were <br /> properly sealed, labeled, and immediately placed in an ice-chest containing ice for transport. The soil <br /> samples were delivered under chain-of-custody to a certified independent analytical laboratory. <br /> 3.4 LABORATORY ANALYSIS <br /> The soil samples collected from the site were transported the day of collection to Columbia Analytical,Inc. <br /> in Canoga Park,California. The soil samples collected from below the former underground tanks and from <br /> 5 <br />
