Ground water samples <br /> to be analyzed for TPH-g,BTEX,and fuel additives will be collected into 40-milliliter(ml)volatile <br /> organic analysis (VOA) vials containing 0.5 ml 18% hydrochloric acid solution as a sample <br /> preservative. Following collection, the samples will be placed on ice and kept in a cooler until <br /> delivered to the laboratory for analysis.Chain of custody protocols will be used to document sample <br /> custody transfer from the field to the analytical laboratory.A chain-of-custody form will accompany <br /> the samples. <br /> 4.5. EQUIPMENT DECONTAMINATION/WASTE 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 and rinseate generated <br /> during drilling and ground water sampling activities will be containerized in properly labeled,DOT- <br /> approved 55-gallon drums and stored on-site in an area lacking public access.Disposal alternatives <br /> will be evaluated based on the results of soil and ground water analyses. <br /> 5.0.
