operations, and subsequent to drilling additional boreholes, the drill rig, tools, augers and <br /> any other downhole tools or equipment was thoroughly steam cleaned to prevent borehole <br /> cross contamination. Soil samples were collected using a California modified split-spoon <br /> sampler fitted with two 6 inch by 2 inch O.D. brass liners and two 3 inch by 2 inch O.D. <br /> aluminum liners. Soil samples were collected by removing the auger string and driving the <br /> California modified split spoon sampler and rod with a sledge hammer. The samples were <br /> then labeled, logged on a chain-of-custody/sample management form, put in a Zip-loc <br /> plastic storage bag, placed in an ice chest with Blue Ice, and kept cool for transport to <br /> AEMC's state certified laboratory for analyses. The contents of the remaining tubes were <br /> checked for odor and discoloration, and extruded and logged for changes in soil lithology. <br /> Soil samples were analyzed for Total Petroleum Hydrocarbons (TPH—[diesel range]), <br /> Benzene, Touluene, Xylene, and Ethylbenzene (BTXE), and Total Recoverable <br /> Petroleum Hydrocarbons (TRPH). Table 2 (pages 15-16) presents a summary of the <br /> analytical results. <br /> «ate m m zs Page 14 <br />
