GERAGHTY & MILLER, INC g <br /> The soil boring will be installed by Precision Sampling, Inc. (Precision). The Precision <br /> ' sampling ng utilizes a hydraulic hammer to drive the hollow, cylindrical EnviroCoreTM <br /> sampling rods into the ground to collect continuous soil cores Two nested sampling rods are <br /> ' driven simultaneously the small-diameter inner sampling rods are used to obtain and retrieve <br /> the soil cores, and the larger-diameter outer rods serve as temporary drive casings This equip- <br /> ment provides a technique for collecting soil samples below the water table while mmunizing <br /> tthe potential for cross-contamination from groundwater encountered in the boring. <br /> Soil samples collected using the EnviroCoreTM stainless steel sleeves will be sealed, <br /> placed on ice, and transported to Sequoia Analytical, Inc. (Sequoia), along with appropriate <br /> tchain-of-custody documentation All of the soil samples will be analyzed for TPH as gasoline <br /> (USEPA Method 801.5, modified) and BTEX with MTBE (USEPA Method 8020,modified) <br /> ' <br /> Project No. RC0309 010 <br />
