I ' 31 March 2004 AGE-NC Project No 03-1077 ' Page 3 of 7 I pushed to the specified depth, then the tip was withdrawn to expose a core barrel fitted with two six- inch long stainless steel sleeves, and the soil sampler was pushed down again to retrieve a 1-foot soil sample Soil samples were preserved by covering both ends of the bottom stainless steel sleeve with I Teflon sheets, capping, and sealing with tape Each sample sleeve was labeled with soil probe boring location, depth, time, date and sampler's initials and placed in a chilled container Soil-sample duplicates from the top sleeve were visually described on boring logs in accordance with the Unified Soil Classification System(USCS) Boring logs are included as Appendix B I2 2 2 Groundwater Sample Collection I Groundwater samples were collected from specified depth intervals (zones) based on the acquired CPT-lrthology data indicating favorable conditions for sampling A HydroPunch sampling tool was pushed into the specified zone, then withdrawn approximately four feet to expose an inlet screen, the interior of the sampling tool filled with water and a 1-inch outer diameter(O D ) stainless steel bailer was lowered and utilized to extract a groundwater sample IGroundwater samples were collected from CPT boring locations at the following intervals • CPT-2 was sampled between 65 and 70 feet bsg, between 82 and 86 feet bsg, between 94 and I98 feet bsg, and between 106 feet and 110 feet bsg, • CPT-3 was sampled between 65 and 69 feet bsg, between 80 and 84 feet,between 96 and 100 ' feet bsg, and between 110 and 114 feet bsg, and • CPT-4 was sampled between 65 and 70 feet bsg,between 80 and 84 feet, and between 107 and 111 feet bsg I The groundwater samples collected in the intervals between 65 and 70 feet bsg, 95 and 100 feet bsg and I below 105 feet bsg were from permeable sand zones as specified in the EHD work plan approval letter of 30 May 2003,the samples collected in the interval between 80 and 85 feet bsg were from an interval of possibly low-permeability clay, silty clay/clayey silt and silt which may have been a barrier to vertical migration of contaminants Each water sample was transferred into 40-m1 VOA vials containing 0 5 ml 18%hydrochloric acrd as I a sample preservative After collection, the samples were properly labeled and placed in a chilled container I 2 2 3 Equipment Decontanunation and Boring Abandonment IAdvanced CeoEnvironmental,Inc
