' 20 June 2006 AGE-NC Project No. 01-0839 Page 5 of 8 ' of the second sleeve will be covered with Teflon sheets, capped, and sealed with tape. Appropriately sealed and labeled samples will be placed in a chilled container and transported under chain of custody procedures to a DHS-certified laboratory for analysis for the constituents listed in Section 2.2.. Each sample sleeve will be labeled with the boring designation,depth,time,date,and sampler's initials. Soil encountered in the borings will be visually classified by an AGE geologist in ' accordance with the Unified Soil Classification System(USCS). Additionally, soil samples will be field-screened for the presence of volatile organic compounds using an organic vapor meter(OVM), equipped with photo-ionization detector(PID). Soil sample descriptions and OVM readings will be recorded on a log for each boring. 3.1.2. Grab Ground Water Sample Collection and Analysis One grab ground water sample will be collected from the proposed soil boring. The boring will be ' advanced to the top of the ground water table, as identified by collection of a saturated soil sample, to collect a grab ground water sample. Once ground water has been encountered, samples will be collected with a Hydropunch water sampling assembly; a 2-inch diameter polyvinylchloride(PVC) ' casing with a 5-foot long, 0.010-inch slotted well screen at the lower end will be temporarily installed in the borehole and a grab ground water sample will be collected by lowering a Teflon, ' disposable bailer through the hollow center of the auger rods into the screened section. Ground water samples will be transferred into laboratory-supplied,40-milliliter(ml)volatile organic analysis (VOA) vials containing 0.5 ml 18% hydrochloric acid solution as a sample preservative. Following collection, the samples will be appropriately labeled, placed in a chilled container, and transported under chain of custody procedures to a DHS-certified laboratory for analysis for the constituents listed in Section 2.2.. 3.2. WELL INSTALLATION PROCEDURES Utilizing a CME-75HT truck-mounted, hollow-stem drill rig equipped with 8.25-inch diameter ' hollow-stem augers,the monitoring well pilot soil boring will be advanced to a depth of 80 feet bsg and the SVE well pilot soil borings will be advanced to depths of 30 feet and 60 feet bsg.Relatively undisturbed soil samples will be collected from each soil boring at 5-foot intervals using a California modified split-spoon sampler fitted with 2-inch diameter, 6-inch long brass sleeves.Upon removal from the sampler,the sample sleeves will be separated with a knife.The exposed ends of the second sleeve will be covered with Teflon sheets,capped,and sealed with tape. Soils sampled in the borings ' will be visually classified by an AGE geologist in accordance with the USCS. Additionally, soil samples will be field screened for the presence of volatile organic compounds using an OVM equipped with a photo-ionization detector PID. Soil sample descriptions and PID readings will be Advanced GeoEnvironmental,Inc.
