sufficiently driven into the soil profile so as to allow no headspace in the brass liner. <br /> Following retrieval, both ends of the brass liner will be covered with Teflon, securely capped <br /> with polyethylene end caps, labeled, and placed in an ice chest containing Blue Ice and kept <br /> at 4' C for transportation to the analytical laboratory for chemical analysis. <br /> If soil samples cannot be safely collected from the excavation, soil samples will be collected <br /> using the backhoe. Immediately upon removal of the tank, a backhoe bucket of native soil <br /> from each sample location will be taken. After filling the backhoe shovel from the desired <br /> location in the bottom of the excavation, a large solid chunk of soil will be chosen for sample <br /> collection. Using a hand trowel, approximately 6 inches of soil will be rapidly scraped away <br /> from the surface of the soil. Soil samples will then be collected as previously described. <br /> Water samples will be collected using a disposable bottom-entry polyethylene bailer. The <br /> collected sample will be transferred into a 40-milliliter VOA vial with as little aeration as <br /> possible, and allowing no headspace in the vial. A Teflon septum inside the vial's cap will be <br /> used ti seal the vial. The collected sample will be labeled and placed in an ice chest <br /> maintained at 4° C for transport to the analytical laboratory for chemical analyses. <br /> All samples collected will be labeled with the sample identifier, location, sampler's name, <br /> time and date of sample collection, and analyses requested using a black indelible marking <br /> pen. All samples collected will be recorded on a Sample Management/Chain-of-Custody <br /> form which will track the sample from time of collection to delivery at the analytical <br /> laboratory. All information recorded on the Sample Management/Chain-of-Custody form <br /> will be entered in ink. <br /> page 17 <br />
