The soil borings were accomplished using a mobile mounted <br /> drilling rig employing the use of a hollow stem flight auger no less than 3 1/4- <br /> inch 1 d. and 8 718 O.d. <br /> All drilling equipment was thoroughly steam-cleaned before drilling began, to <br /> prevent the introduction of contamination from off site, and between borings to <br /> prevent cross contamination. <br /> The borings were logged under the direct supervision of a registered <br /> professional using the Unified Soil Classification System (Appendix Q. The <br /> color, texture, moisture, plasticity, consistency of the earth materials, pertinent <br /> soil or bedrock characteristics, and any evidence of contamination were noted. <br /> All water-bearing zones and the depths at which they were encountered were <br /> noted on these logs. <br /> All borings were dulled in such a manner as to prevent cross contamination <br /> lip between strata Exploratory soil bonngs within the unsaturated zone were <br />' backfilled with a cement and three percent (3 J) Bentonite mixture <br />
