30 March 2009 <br />AGE -NC Project No. 07-1569 <br />Page 3 of 4 <br />methyl tertiary -butyl ether (MTBE), and 1,2-dichloroethane (1,2 -DCA), in accordance with <br />EPA Method 8260B. <br />Prior to use, all sampling tools for sample collection were thoroughly rinsed with clean water after <br />being washed with a solution of Alconox. All probing rods were cleaned prior to advancement at <br />each probe boring location. <br />Following grab ground water sample collection, each borehole was permanently sealed to prevent <br />the vertical migration of contaminants. Under EHD oversight, the boreholes were backfilled with <br />a mixture of Portland cement slurry and bentonite, from total depth to surface grade. <br />FINDINGS <br />Petroleum hydrocarbons and volatile organic compounds were not reported, at or above laboratory <br />detection limits, in any of the ground water samples analyzed. Analytical results are summarized in <br />Table 1. A copy of the CTEL laboratory report (CTEL Project No. CT214-0903001), QA/QC report <br />and chain of custody form are included in Appendix C. <br />Based on the findings presented in this report, AGE concludes that there are no petroleum - <br />hydrocarbon impacts to ground water as a result of utilizing the site for glass disposal. No further <br />environmental assessment is required. <br />LIMITATIONS <br />AGE's professional services were performed using the degree of care and skill ordinarily exercised <br />by environmental consultants practicing in this or similar localities. The findings were based <br />primarily upon analytical results provided by an independent laboratory. Evaluations of the <br />geologic/hydrogeologic conditions at the site for the purpose of this investigation were made from <br />Advanced GeoEnvironmental, Inc. <br />11 <br />
