------------- <br /> Subsurface Environmental Investigation <br /> Abandoned Lerner service Station, <br /> Lodi Californiatmber 21,, 1988 <br /> AGS 38055-1 <br /> analysis by lowering approximately half the length of a Teflon <br /> #w bailer past the interface. The bailer was retrieved, and the <br /> water sample was examined for floating product, sheen, or other <br /> subjective evidence of hydrocarbon contamination. . Ob.vious ` <br /> moderate product odor <br /> and a slight sheen were detected. After <br /> 6N? <br /> subjective analyses, the monitoring well was developed by surge- <br /> blocking. <br /> On August 29, 198&, a geologist from Applied GeoSystems visited <br /> the site to measure the depth to water in the monitoring well, <br /> subjectively analyze the ground water in the well, and purge and <br /> sample the well. Subjective evidence showed a slight sheen of <br /> gasoline on the ground water. The initial depth to ground water <br /> L was 40.38 feet below the ground surface. A ground-water sample <br /> was collected from the air-fluid interface, as described above, <br /> examination of thy_ water revealed a slight sheen and obvious <br /> strong product odor. After.` subjective analysis,Y the monitoring <br /> well was purged of approximately55 <br /> gallons using a electric <br /> submersible pump. All water purged from the moni*oring well was <br /> placed-in the Department of Transportation 55-gallon drum and <br /> remains the resp <br /> onsibilit ►.' of RAMCON and 'the site::.owner.. <br /> J1 . <br /> - <br /> After the well was purged; a ground-water sample was ccllected by <br /> lowering a clean Teflo:,' bailer.approximately z feet pa t the air <br /> la ` : <br /> A,017/r'-pc l GggoSVst&MS _ <br />
