ANALYTICAL RESULTS OF GRAB GROUND WATER SAMPLES <br /> ' One grab ground water sample was collected from boring CPT-1 at a depth of 88 feet bsg and two <br /> ' grab ground water samples were collected from boring CPT-2 at depths of 95 feet and 115 feet bsg. <br /> No petroleum hydrocarbon constituents were detected at or above laboratory reporting limits. <br /> ' Analytical results for the CPT grab ground water samples are summarized in Table 1.The laboratory <br /> report(CTEL Project No. CT214-0611174),quality assurance and quality control(QA/QC)reports, <br /> and chain of custody forms are included in Appendix E. <br /> 5.3. ANALYTICAL RESULTS OF SOIL SAMPLES <br /> ' A total oftwenty-one soil samples collected from boring CPT-2 and from monitoring and vapor well <br /> pilot soil borings MW5, VWI, VW3, and VW6. <br /> 1 MTBE was detected in soil samples VW1-35, VW145, and VWI-60 at concentrations of <br /> 0.042 milligrams per kilogram(mg/kg),0.21 mg/kg,and 0.39 mg/kg,respectively.Ethylbenzene was <br /> ' detected in soil sample VW6-50 at a concentration of 0.016 mg/kg. <br /> No additional petroleum hydrocarbon constituents were detected at or above laboratory detection <br /> ' limits in the soil samples analyzed.Analytical results of the soil samples are summarized in Table 2. <br /> The laboratory reports (CTEL Project Nos. CT214-011174, -0612137, and -0612151), QA/QC <br /> ' reports, and chain of custody forms are included in Appendix F. <br /> 6.0. SOIL VAPOR EXTRACTION PILOT TESTS <br /> On 26 December 2006,an 8-hour pilot testwas conducted using shallow-screened vapor well VW-2, <br /> ' screened from 15 feet to 30 feet bsg, as the extraction well. On 27 December 2006, an abbreviated <br /> pilot test was conducted using deep-screened vapor wells, screened from 45 feet to 60 feet bsg, as <br /> the extraction wells. <br /> 6.1. SHALLOW WELL SVE PILOT TEST <br /> ' On 26 December 2006, an 8-hour SVE pilot test was conducted at the site using shallow-screened <br /> vapor well VW-2, screened from 15 feet to 30 feet bsg, as the extraction well. The pilot test was <br /> ' performed to provide SVE data for the proper design of a soil remediation system. The test was <br /> conducted using a Fuji regenerative 150 standard cubic feet/minute (scfm) blower powered by a <br /> ' Advanced GeoEnvironmental,Inc. <br /> 1 <br />
