observation wells to depths of approximately 60 feet bgs. Groundwater samples will be collected <br /> from the four deep SVE wells. These four deep SVE wells will investigate the deeper portion of the <br /> vadose zone at the LNC site. It is anticipated that approximately four to eight additional 2-inch <br /> diameter Schedule 40 PVC SVE wells will be drilled to a depth of about 25 feet bgs at the LNC site <br /> to investigate the shallow vadose zone at the LNC site. <br /> In addition to the above described effort, a single groundwater monitoring well will be installed <br /> immediately downgradient of the LNC site in order to monitor groundwater conditions within the <br /> first water bearing zone. This well will be drilled and completed to a depth of 60 feet bgs. <br /> The shallow and deep SVE wells will be used for SVE pilot testing. If significant water is produced <br /> during the SVE pilot test from the deep wells completed in the groundwater table then these wells <br /> will be backfilled with sand in the wellbore to a depth of approximately five feet above the <br /> groundwater surface. At that point the wells will be used only to extract soil vapor from the deeper <br /> zones. <br /> (3)Soil gas and groundwater laboratory analysis for volatile organic compounds. <br /> (4)Investigation derived waste disposal. <br /> (5)Data evaluation and reporting. <br /> (6) Site Characterization Report and Remediation Feasibility Study. <br /> In addition, a Soil Vapor Extraction(SVE)Pilot Test Workplan has been prepared and is presented <br /> within this Workplan. The SVE Pilot Test Workplan is designed to obtain sufficient information <br /> to determine if a full-scale SVE soil remediation system is technically viable and warranted. <br /> Main\D:\Cnvironmenla1\LNC\\101 52007,wpd 3 <br />
