Work Plan—Soil Boring Installation Page 2 <br /> Boudanes Property <br /> Project 422.2 <br /> February 19, 2004 <br /> 2.1.1 Geo-Probe Soil Borings <br /> The two Geo-Probe soil borings will be advanced to a depth sufficient to <br /> penetrate the surface of groundwater. This is estimated to lie at a depth of <br /> about 15 feet below grade. The borings, designated S13-1 & SB-2 will be located <br /> at locations shown on the attached site map. <br /> Soil samples will be collected at 5-foot intervals in each boring and at the base of <br /> each boring. A groundwater sample will also be collected from the base of each <br /> boring. <br /> The soil borings will be drilled using 1.5" outside diameter Geo-Probe drilling <br /> equipment owned and operated by V & W Drilling (C-57 License #720904). The <br /> borings will be advanced to a total depth of about 15 to 20 feet below grade. <br /> Upon reaching total depth in each boring and collecting a final soil and <br /> groundwater sample, the boring will be filled to grade with neat cement. <br /> The Geo-Probe is a truck mounted drilling system that uses direct push <br /> methodology to collect soil and groundwater samples. Four foot long by 1.5 inch <br /> diameter stainless steel rods are pushed or hammered into the ground using a <br /> hydraulic ram or the hydraulically actuated hammer mounted on the ram. Soil <br /> samples are collected using a 4-foot long by 1.5 inch inside diameter drive <br /> sampler lined with a plastic sample sleeve. <br /> 2.1.2 Geology <br /> A detailed log will be made of each boring. The information to be noted include <br /> such data as sample depths, soil / sediment type and description (color, texture, <br /> composition, hardness, moisture content, and post-depositional changes that <br /> have occurred in the sediments), and horizons of detectable contamination <br /> (detected by field methods). <br /> 2.2 Soil Sampling and Analyses <br /> The soil sample collection procedure will be as follows. Upon retrieval, the end <br /> of each plastic sample tube removed from the coring device and possibly <br /> submitted for laboratory analysis will be sealed with Teflon sheets, capped with <br /> plastic end caps, secured with tape, labeled and placed in a cooler at 4° Celsius. <br /> It is not expected that any soil samples will be submitted for laboratory analysis. <br /> The will, however be retained in Geo-Phase Environmental Inc.'s sample <br /> refrigerator pending the results of groundwater sample analysis. <br /> All sampling equipment will be thoroughly cleaned before and between uses. <br /> Any drilling steam-clean water will be containerized in appropriate DOT <br /> 2937 Veneman Avenue, Suite B240 Geo-Phase Environmental Inc.
