24 December 2014 <br />AGE Project No. 14-3154 <br />Page 5 of 7 <br /> <br />Advanced GeoEnvironmental Inc. <br /> <br /> <br />Fifteen soil samples were analyzed for CAM 17 metals. Analytical results for the CAM <br />17 analysis detected concentrations of arsenic as high as 2.4 milligrams per kilogram <br />(mg/kg), Chromium as high as 7.5 mg/kg, Cobalt as high as 11 mg/kg, Copper as high <br />as 21 mg/kg, Lead as high 6.4 mg/kg, Nickel as high as 12 mg/kg, Vanadium as high as <br />36 mg/kg and Zinc as high as 78 mg/kg from all soil samples. <br /> <br />Additional analytes of concern were non-detect. <br /> <br />Analytical results of soil samples are summarized in the soil laboratory report (CTEL <br />Project No. CT214-1412043 and 1412058, quality assurance and quality control <br />(QA/QC) reports, and chain of custody forms are included in Appendix B. <br /> <br /> <br />3.3. ANALYTICAL RESULTS OF GROUNDWATER SAMPLES <br /> <br />A total of five (5) groundwater samples were collected from borings AB1 through AB7 <br />and four (4) from collected from borings AB8 through AB16 and submitted for analysis <br />for the constituents for fuel oils (diesel range compounds) and were non-detect for fuel <br />range hydrocarbons. Five groundwater samples were additionally analyzed from <br />borings AB1 through AB7 for fuel oils (diesel range compounds) and were non-detect <br />for fuel range hydrocarbons. <br /> <br />Four groundwater samples were collected from borings AB8 through AB16 and <br />submitted for analysis for the constituents for CAM 17 metals. Analytical results for the <br />CAM 17 analysis detected concentrations of chromium as high as 0.014 milligrams per <br />liter (mg/L), Copper as high as 0.018 mg/L, Nickel as high as 0.018 mg/L, Vanadium as <br />high as 0.073 mg/L and Zinc as high as 0.049 mg/L from all grab groundwater samples. <br /> <br />Target analytes for volatile organic compounds were not detected in any of the <br />groundwater samples collected during the December 2014 investigation. Additional <br />analytes of concern were non-detect. <br /> <br />Analytical results of groundwater samples are summarized in the groundwater <br />laboratory report (CTEL Project No. CT214-1412043 and 1412058), quality assurance <br />and quality control (QA/QC) reports, and chain of custody forms are included in <br />Appendix B. <br /> <br /> <br />4.0. SUMMARY/CONCLUSIONS <br /> <br />The results of the December 2014 assessment with soil and groundwater sampling are <br />as follows: <br /> <br /> A total of twenty-one (21) soil borings were advanced at the site: eleven to 10
