Ground water samples <br />' for BTEX, TPH-g, VOCs, and oxygenates analyses will be collected into 40-m1 VOA vials . <br /> containing 0.5-m1 of hydrochloric acid as preservative. Samples for.TPH-mo analysis will be <br /> collected into unpreserved 1-liter amber glass containers. Following collection the samples will be <br /> ' placed on ice and kept in a cooler until delivered to the laboratory for analysis. Chain-of-custody <br /> protocols will be used to document sample custody transfer from the field to the analytical <br /> laboratory. A-chain-of-custo dy form will accompany the samples. <br /> ' 3.7. EQUIPMENT DECONTAMINATION <br /> All sampling tools used for sample collection will be thoroughly rinsed with clean water after being <br /> ' washed with a solution of Alconox. All probing rods will be cleaned prior to advancement at each <br /> probe boring location. Hollow-stem augers will be steam-cleaned prior to each boring. <br /> 3.8. BORING ABANDONMENT <br /> ' All soil borings not completed as monitoring wells will be permanently sealed to prevent vertical <br /> migration of contaminants. Soil borings shall be abandoned by backfilling with bentonite or cement- <br /> bentonite slurry from the total depth to surface grade. <br /> 1 <br /> a <br /> Advanced CeoEnvironmental,Inc. <br />
