November 7, 1986 AGS 8691-3 <br /> Beacon Service Station #1-502 - Lodi, California <br /> During drilling, soil samples were collected at intervals of five <br /> feet or less, using a modified California split spoon sampler <br /> equipped with laboratory-cleaned brass sleeves. Samples were <br /> collected by advancing the boring to a point immediately above <br /> the sampling depth, then driving the sampler into the native soil <br /> through the hollow center of the auger, The sampler was then <br /> driven 18 inches with a standard 140 pound hammer dropped 30 <br /> inches. <br /> The number of blows required to drive the sampler each successive <br /> six inches was counted and recorded to give an indication of soil <br /> consistency. Boring Logs for the holes drilled during this <br /> investigation are presented in Plates P-5 through P-10. Soil <br /> samples collected for possible chemical analyses were sealed with <br /> aluminum foil, plastic caps, and air-tight tape. They were <br /> immediately labeled and then placed in iced storage for transport <br /> to the analytical laboratory. <br /> Drill cuttings were placed in fifteen appropriately lined D.O.T. <br /> 17H 55-gallon capacity drums, which were sealed and left on site. <br /> These drums remain the responsibility of Beacon Oil Company. <br /> Applied GeoSystems can, with the authorization of Beacon Oil <br /> Company, arrange for the transport and disposal of the soil. <br /> 4 <br /> A,vv/ied GeoSystems <br />
