30 July 2007 AGE -NC Project No. 03-1055 Page 8 of 9 of the chemicals listed in Section 2.4.. The soil in the two remaining sleeves will be visually classified by AGE personnel in accordance with the Unified Soil Classification System (USCS) and field -screened for the presence of volatile organic compounds using an organic vapor meter (OVM) equipped with a photo -ionization detector (PID: Thermo Environmental 580,10.0eV [or equivalent], calibrated to isobutylene). 3.3.2. Direct Push Soil Boring Soil Sample Collection and Analysis Soil samples will be collected from the direct push boreholes at selected depth. Following sample collection, the exposed ends of the leading or other selected sleeve will be labeled with the boring location, depth, time, date and sampler's initials; the appropriately sealed and labeled samples will be placed under ice in a chilled container and will be transported under chain -of -custody to a DHS - certified laboratory for analysis of the chemicals listed in Section 2.4. The soil in the two remaining sleeves will be visually classified by AGE personnel in accordance with the USCS and field - screened for the presence of volatile organic compounds using an OVM equipped with a PID (Thermo Environmental 580, 10.0eV [or equivalent] and calibrated to isobutylene). 3.4. GRAB GROUND WATER SAMPLING AND ANALYSIS Grab ground water samples will be collected from the off-site direct -push soil borings at approximately 10 feet bsg (first encountered ground water). The samples will be collected utilizing a Geoprobc water sampling assembly fitted with a pre -cleaned one -inch diameter 0.01 -inch slotted temporary well screen. The ground water sample will be extracted by lowering a Teflon hose equipped with a ball-valve through the hollow center of the push rods into the screen section. Each ground water sample will be transferred into three Iaboratory-supplied, 40 -milliliter volatile organic analysis vials without sample preservative and one 1 -liter amber glass container without sample preservative. Care will be taken to ensure that visible air bubbles are not present in the vials after filling and capping. Grab ground water sample containers will be labeled with each well designation, date, time, and sampler's initials. After collection, the samples will be properly labeled, placed in a chilled container and transported under chain -of -custody to DHS -certified laboratory for analysis of constituents discussed in Section 2.4.. Laboratory reports for the ground water analyses, testing methods, laboratory QA/QC reports, and sample chain of custody documentation will be presented in a report with findings and recommendations.
