i t 29 May 2002 AGE-NC Project No. 02-0912 Page 2 of 4 DRILLING AND SAMPLE COLLECTION On 17 May 2002, three soil probe borings (P-1 through P-3) were advanced at the site as part of assessment activities.The area proposed for a fourth probe boring was not accessible;an access alley was blocked by non-operational equipment. The field work was conducted as outlined in the AGE- prepared,Phase II Site Assessment Work Plan, dated 30 April 2002. Soil probe borings P-1 through P-3 were advanced utilizing a truck-mounted Geoprobe 5400, equipped with 1.125-inch diameter probe rods with an attached 2.15-inch diameter soil sampler, using "direct push" technology. The three borings were advanced vertically to depths of 30 feet below surface grade (bsg) for collection of soil samples and grab ground water samples. Soil samples were collected at 5-foot intervals beginning at 10 feet bsg to total depth of each boring. Each sample was collected utilizing a 1.125-inch Geoprobe soil sampling assembly loaded with four six-inch brass sleeves.After collection,the ends of the second brass sleeve were covered with Teflon sheets,capped and sealed with tape. The sleeve was labeled with soil probe boring location,depth, time,date and sampler's initials and then placed in a chilled container.Afterwards,the soil from one of the three remaining sleeves was field-screened for the presence of volatile organic compounds using an organic vapor meter(OVM). Grab ground water samples were collected from probe borings P-1 through P-3 using a temporary PVC screen. The probe rods were advanced to a depth approximately four feet below the inferred water table(approximately 30 feet bsg).The hollow-steel rod assembly was pulled up approximately 4 feet,and a screened casing was inserted into the saturated zone.Ground water was allowed to enter the casing, and samples were retrieved using a modified PVC tubing bailer. Sufficient sample was collected to fill three 40-m1 EPA-approved VOA vials containing 0.5 ml 18%hydrochloric acid as a preservative. The ground water sample containers were labeled with probe boring designation, date, time, and samplers initials and then placed in a chilled container. Following soil and ground water sample collection, all probe-boring locations were backfilled to surface grade with Portland cement. EQUIPMENT DECONTAMINATION Prior to sample collection, Geoprobe soil sampling equipment was thoroughly rinsed with clean water after being washed with a solution of Alconox. Geoprobe rods were thoroughly cleaned prior to soil probe boring advancement. Advanced GeoEnviron mental,Inc.
