Ground water samples <br /> to be analyzed for TPH-g, BTEX and fuel additives will be collected into 40-m1 volatile organic <br /> analysis (VOA) vials which may contain 0.5-m1 of hydrochloric acid as preservative. Following <br /> collection,the samples will be placed on ice and kept in a cooler until delivered to the laboratory for <br /> analysis.Chain-of-custody protocols will be used to document sample custody transfer from the field <br /> to the analytical laboratory. A chain-of-custody form will accompany the samples. _ <br /> 3.5. EQUIPMENT DECONTAMINATIONIWASTE MANAGEMENT <br /> All sampling tools used for sample collection, except for disposable bailers, will be thoroughly <br /> rinsed with clean water after being washed with a solution of Alconox. All down-hole drilling <br /> equipment will be pressure washed prior to starting each boring. Cuttings generated during drilling <br /> and rinseate generated during drilling and ground water sampling activities will be containerized in <br /> properly labeled DOT-approved 55-gallon drums,and stored on-site in an area lacking public access. <br /> Disposal alternatives will be evaluated based on results of soil and water analysis. <br /> Advanced GeoEnvironmental,Inc. <br />
