KLEINEELDER &ASSOCIATES <br /> i <br /> 3 SCOPE OF STORK - <br /> 3.1 DRILLING OF SOIL BORINGS <br /> Three soil borings will be drilled using a truck mounted drill rig <br /> equipped with 8--inch hollow stem augers. During the drilling, an <br /> experienced environmental geologist will classify the subsurface soils, <br /> collect soil samples, and log the boreholes. <br /> To minimize cross--contamination all augers and associated equipment will <br /> be steam cleaned prior to the drilling of each borehole, The sampling <br /> equipment will be cleaned with a trisodium phosphate wash and a distilled <br /> water rinse prior to the collection of each soil sample. <br /> Drill cuttings from boring operations will be placed on plastic and stock <br /> piled on site. Final disposition of drill cuttings is the sole <br /> responsibility of the client. <br /> 3.2 SOIL SAMPLING PROCEDURES <br /> Soil samples will be collected for future chemical analysis if requested <br /> and to complete a lithologic log. Samples will be collected at five foot <br /> intervals starting at a depth of five feet below the ground surface down <br /> to just above the ground water table. <br /> Soil samples will be collected by advancing the boring to a point <br /> immediately above the sampling depth and then driving a Modified <br /> California Sampler lined with three brass tubes into the undisturbed <br /> soil. The sampler will then be removed from the bottom of the boring and <br /> the bottom (third) tube sealed with aluminum foil and tight fitting <br /> _ - <br /> plastic - caps. The -sealed......tube...-will ...be..immediately stored in an iced <br /> cooler. The soil samples will be retained under chain—of-custody in <br /> secured refrigerated storage for future reference or analysis. <br /> 3fi-87-1037 <br /> 3 <br />
