I Stockton Taxi Cab /Sunland Gasoline <br /> • 2085 East Fremont Street <br /> Stockton, California <br /> ' Report of Findings: <br /> Lateral and Vertical Extent of Soil and Groundwater Contamination <br /> 1.0 Project Identification <br /> On December 15, 1998, Sunland Gasoline had two (2) underground storage tanks <br /> j (UST's) removed by Advanced GeoEnvironmental, Inc. Petroleum hydrocarbon, volatile <br /> aromatics, and oxygenate contamination was encountered in the shallow subsurface <br /> located in the vicinity of the former UST, product piping, and dispenser locations. The <br /> purpose of this investigation is to characterize the lateral and vertical extent of the <br /> contaminated media(soil and groundwater) and to determine the risk to human health and <br /> the environment posed by the subject site. <br /> 2.0 Site Location and History <br /> Sunland Gasoline is located in a commercial area in the city of Stockton, an incorporated <br /> area of San Joaquin County, California (Figures 1 and 2).

Upon removal of the UST's, soil samples were <br /> collected to determine the presence or absence of petroleum hydrocarbons, Benzene, <br /> iToluene, Ethyl Benzene, Xylene (BTEX), fuel oxygenates including di-isopropyl ether <br /> (RIPE), ethyl tertiary butyl ether (ETBE), tertiary amyl methyl ether (TAME), tertiary- <br /> butyl alcohol (TBA), and methyl tertiary butyl ether (MTBE), and lead. A total of fifteen <br /> (15) soil samples were collected from this site under the direction of the San Joaquin <br /> County Public Health Services-Environmental Health Division (PHS-EHD). <br /> ' On December 15; 1998, a total of seven (7) soil samples were collected from beneath the <br /> former UST locations and from the stockpiled soil, by a representative of Alpha <br /> Analytical Laboratories, Inc. (AAL). Four (4) soil samples were collected beneath the <br /> north and south ends of UST No. 1 and UST No. 2 at depths of approximately 16 feet <br /> • below surface grade. Three soil samples were collected from the stockpiled soil removed <br />
