PID readings and soil classifications were recorded on <br /> boring logs, provided in Appendix A. <br /> EQUIPMENT DECONTAMINATION <br /> Prior to sample collection, soil sampling equipment was thoroughly rinsed with clean water <br /> after being washed with a solution of Alconox. Direct-push rods and hand-augers were <br /> thoroughly cleaned prior to soil probe boring advancement. <br /> BORING ABANDONMENT <br /> Following soil sample collection, each boring was permanently sealed to prevent vertical <br /> migration of potential contaminants. Soil borings were abandoned by backfilling with <br /> portland cement from the total depth to surface grade. <br /> FINDINGS <br /> Organic vapors were not detected in any samples collected using the PID. Furthermore, <br /> no petroleum hydrocarbon-like odors were noted in any of the samples collected. Boring <br /> logs for borings B1 through B6 are provided in Appendix A. <br /> Target analytes were not reported in any of the analyzed soil samples at or above <br /> laboratory reporting limits. The laboratory report (CTEL Project No. CT214-1202004), <br /> quality assurance and quality control (QA/QC) report, and chain of custody forms are <br /> included in Appendix B. <br /> CONCLUSIONS <br /> Based on the data collected from soil borings B1 through B6, AGE concludes there is no <br /> significant VOC-impact to soil in the areas of investigation, including the former UST area <br /> (B1 through B3), beneath Warehouse 4 (B4 and 135), and the area near the storm <br /> collection drain outside of Warehouse 4 (136). AGE has no recommendations for additional <br /> investigations at the subject property. <br /> Advanced GeoEnvironmental,Inc. <br />
