19 September 2003 <br /> AGE-NC Project No. 03-1043 <br /> Page 2 of 4 <br /> DRILLING AND SAMPLE COLLECTION <br /> On 07 August 2003, four soil probe borings (B-5, B-6, B-7, and B-8) were advanced at-the site as <br /> part of assessment activities. Proposed borings B-1 and B-4 were not completed at this time due to <br /> the geoprobe encountering refusal at approximately.45' below surface grade (bsg) in proposed <br /> borings B-1 and B-2. On 05 September 2003 AGE returned to the site and collected ground water <br /> samples from borings B-1 and B-2 utilizing a CME-75HT drill rig equipped with 8.25 inch hollow <br /> stem augers. AGE chose the completed boring locations in order to collect a representative sample <br /> of the subj ect property's subsurface.The field work was conducted as outlined in the AGE prepared, <br /> Phase 11 Site Assessment Work.Plan and Phase II Site Assessment Work Plan Addendum, dated 17 <br /> June 2003 and 18 August2003, respectively. <br /> Soil probe borings B-5,B-6,B-7,and B-8 were advanced utilizing a truck-mounted Geoprobe 5400, <br /> equipped with 1.125-inch diameter probe rods with an attached 2.15-inch diameter soil sampler, <br /> using "direct push" technology. The three borings'were advanced vertically to depths of 25 feet <br /> below surface grade (bsg) for collection of soil samples. <br /> Soil samples were collected at 5-foot intervals beginning at 5 feet bsg to the total depth of each <br /> boring. Each sample was collected utilizing a 1.125-inch Geoprobe soil sampling assembly loaded <br /> with four six-inch brass sleeves. After collection,the ends of the second brass sleeve were covered <br /> with Teflon sheets, capped and sealed with tape. The sleeve was labeled with soil probe boring <br /> location, depth, time, date and sampler's initials and then placed in a chilled container. In addition <br /> to the above sample preperation, a soil sample from one of the three remaining sleeves was field- <br /> screened for the presence of volatile organic compounds using an photo ionization detector(PID). <br /> Soil probe borings B-1 and B-2 were advanced utilizing a CME-75HT drill rig, utilizing 8.25-inch <br /> diameter hollow-stem augers to advance borings B-1 and B-2.The drill rig and two-man crew were <br /> supplied by Cascade Drilling. Auger returns generated by drilling were stockpiled onsite. <br /> Ground water samples were collected from each boring using a dedicated disposable plastic bailer. <br /> Sufficient sample was collected to fill three 40-m1 EPA-approved volatile organic analysis(VOA)vials <br /> containing 0.5 ml 18% hydrochloric acid as a preservative, one 1 liter amber bottle without <br /> preservative, and two 500-m1 poly containers without perservative. The ground .water sample <br /> containers were labeled with probe boring designation,date,time,and samplers initials and then placed <br /> in a chilled container. <br /> Following soil and ground water sample collection, all probe-boring locations were backfilled to <br /> surface grade with Portland cement. <br /> Advanced QoEnviro3nmentai Inc. <br />
