Drummed water will be labeled with the source of the water to help ensure <br /> appropriate disposal based on contamination levels. <br /> 11.0 SOIL SAMPLING PROTOCOL <br /> 11.1 Sample Collection During Drilling Activities <br /> A proposal will be submitted to the lead regulatory authority with proposed <br /> bonng/sampling locations The exact location and number of borings at each site will <br /> be determined in the field by the Project Geologist/Engineer. <br /> Prior to arriving at the sample site, the drill ng/augers will be steam cleaned and all <br /> ' sample equipment will be cleaned. Cleaning will be conducted on-site on all sampling <br /> equipment between each sample interval <br /> Soil samples will be obtained using a California modified split-spoon sampler containing <br /> three 6-inch long, 2-inch diameter brass tubes The sampler will be driven 18-inches <br /> ahead of the hollow stem auger by a 140-pound hammer with a 30-inch drop M <br /> accordance with American Society for Testing and Materials (ASTM) Methods D 1586- <br /> 84 for split barrel sampling of soil and D 1587-83 for thin-walled tube sampling of soils. <br /> ' The blows required to drive the sampler each 6-inch interval will be recorded on the <br /> boring log The sampler will be removed from the boring and opened to reveal the brass <br /> QAQC10n FNi. <br /> 9 <br />
