i <br /> Proposed Work Plan November 4 , 1988 <br /> U.S.A. Petroleum Station No. 65 , Lodi, California AGS 87050-3 <br /> degree of hydrocarbon contamination in the downgradient <br /> direction. All monitoring wells will be located at least 10 feet <br /> from any property lines. If monitoring wells are located less <br /> than 50 feet from any sewer lines, water will be collected and <br /> analyzed for fecal coliform bacteria as specified by San Joaquin <br /> County regulations. <br /> SOIL BORING AND SAMPLING <br /> Applied GeoSystems will contact Underground Services Alert to <br /> identify public utility lines at the site before we begin <br /> drilling. The soil borings will be drilled using a Mobile B-61, <br /> or similar, drill rig with 8-inch continuous flight, hollow stem <br /> augers. The auger flights will be steam-cleaned prior to use to <br /> minimize the possibility of downhole or crosshole contamination. <br /> The drilling will be performed under the guidance of a field <br /> geologist, and the earth materials in the baring will be logged <br /> as drilled. <br /> During drilling, soil samples will be collected at 5-foot <br /> intervals using a California-modified split-spoon sampler <br /> equipped with clean brass sleeves. Samples will be collected by <br /> advancing the boring to a point immediately above the sampling <br /> 7 <br /> Applied GeoSystems <br />
