Morita Brothers Service Stat <br />N <br />2 NW"• January 23, 1992 <br />and associated product pipelines. The tanks were removed under San Joaquin County <br />Department of Health Services Permit No. 1061. <br />Crisp Construction contracted with Earth Systems Environmental to provide an <br />environmental technician to collect soil samples at the direction of Ms. Eleanor <br />Ratcliff with the San Joaquin County Department of Environmental Health Services. <br />3.0 SOIL SAMPLING <br />Three soil samples (PN -1, PS -2, and PC -3) were collected from beneath the <br />former product pipeline at a depth of 3 feet below surface grade (Figure 2). PN -1 and <br />PC -3 were also positioned to be adjacent to the dispensers on the dispenser island. <br />Two soil samples (TK -1N and TK -1S) were collected from beneath the north and south <br />ends of the former 5,000 gallon underground leaded gasoline storage tank at a depth <br />of 12 feet below the surface grade, respectively. Two soil samples (TK -2N and TK -2S) <br />were collected from beneath the north and south ends of the former 5,000 gallon <br />underground unleaded gasoline storage tank at a depth of 12 feet below the surface <br />grade, respectively. Two soil samples (TK -3N and TK -3S) were collected from beneath <br />the north and south ends of the former 2,000 gallon underground premium unleaded <br />gasoline storage tank at a depth of 12 feet below the surface grade, respectively. One <br />soil sample (TK -4) was collected from beneath the former 500 gallon underground <br />waste oil tank at a depth of 9 feet below surface grade. Two soil samples (SPE -1 and <br />SPE -2) were collected from within the eastern excavation stockpile at 3 feet below the <br />surface of the stockpile. One soil sample (SPW) was collected from within the western <br />excavation stockpile at 3 feet below the surface of the stockpile. The samples were <br />collected from a backhoe bucket immediately after soil excavation and stored in a 2" <br />brass tube, sealed with a teflon liner and end cap. The samples were then labeled, <br />handled and transported according to the United States Environmental Protection <br />Agency (USEPA) protocol to a State of California Department of Health Services <br />(DOHS) certified laboratory. Sample identification and chain -of -custody procedures <br />were utilized for the samples to ensure sample integrity and to document sample <br />possession from the time of collection to its ultimate destination. The sample label <br />identified the job number, sampler, date and time of collection and sample number <br />unique to the sample. <br />EB -8101-1 9201-EO81.RPT <br />
