19 December 2011 <br /> AGE-NC Project No. 11-2006 <br /> Page 3 of 5 <br /> sampling tools to specified depths. <br /> SOIL SAMPLE COLLECTION AND ANALYSIS <br /> Soil samples will be collected at discreet five-foot intervals using a 1.25- or 2-inch <br /> Geoprobe®soil sampling assembly loaded with four six-inch stainless steel sleeves. Upon <br /> sample retrieval, the ends of the second sleeve will be covered with Teflon® sheets, <br /> capped and sealed with tape. <br /> Appropriately sealed and labeled samples will be placed in a chilled container under ice <br /> and transported under chain-of-custody procedure to a CDPH-certified laboratory for <br /> analysis of TPH-all and VOCs. Each sample sleeve will be labeled with the boring <br /> designation, depth, time, date and sampler's initials. Additionally, soil sample duplicates <br /> will be field-screened for the presence of volatile organic compounds using an organic <br /> vapor meter (OVM), equipped with photo-ionization detector (PID). <br /> GRAB GROUND WATER SAMPLE COLLECTION AND ANALYSIS <br /> For the collection of grab ground water samples, the soil boring will be advanced to the top <br /> of the ground water table as identified by collection of a saturated soil sample. Once <br /> ground water has been encountered, a Geoprobe®push-driven water sampling device will <br /> be advanced approximately four feet into the water-bearing zone. Grab ground water <br /> sample will be collected using a Geoprobe®water sampling assemblyfitted with fitted with <br /> a new PVC one-half inch diameter 0.010-inch slotted temporary well screen. The ground <br /> water sample will be extracted using inertial action by lowering Teflon®tubing through the <br /> hollow center of the push rods into the screen section. <br /> Each ground water sample is collected into four laboratory supplied 40-ml volatile organic <br /> analysis (VOA) vials and one laboratory supplied 1-liter amber bottle, both without <br /> preservative. Following collection, appropriately sealed and labeled samples will be placed <br /> in a chilled container under ice and transported under chain-of-custody procedure to a <br /> CDPH-certified laboratory for analysis of TPH-all and VOCs. Each sample container will <br /> be labeled with the boring designation, time, date and sampler's initials. <br /> SOIL VAPOR SAMPLE COLLECTION AND ANALYSIS <br /> Soil borings V1 and V2 will be advanced to a depth of 5 feet bsg using a van or truck- <br /> mounted direct push drilling rig equipped with 1.25-inch, stainless steel, hollow probing <br /> rods. The hollow probing rods will be advanced using the drill rig's hydraulic drive-feed to <br /> Advanced GeoEnvironmen[al,Inc. <br />
