r <br />' 31 October 2005 <br /> AGE-NC Project No. 95-0106 <br /> • Pae 3 of 4. <br /> No additional'analytes'were detected at or above laboratory reporting limits-in wells MW-1 and , ; <br /> MW-4. No analytes were detected at or above laboratory reporting limits in wells MW-2, MW;-3, f <br /> MW-5,.MW-6.(upper), MW-6 (lower) and MW-7...Analytical results'of ground water samples are <br /> summarized in Table 21- The laboratory.report (CTEL-Project No: CT214-0506110),.quality <br />' assurance/quality control (QA/QQ reports and chain of custody forms are included in-Appendix C. <br /> ''Documents confirming the upload 6f laboratory electronic deliverable format(EDF)file's and depth <br /> 1 to water measurements to GeoTracker are included as Appendix D. . . a ,• ,. <br /> 4.0. SUMMARY AND CONCLUSIONS <br /> The following conclusions were drawn from the results of the site investigation:, <br /> • The ground Ovate ow direction was generally north on 10 June 2005, at gradients ranging <br /> ' between 0.016 and 0.006 ftlft.Ground water'elevatioris decreased slightly,but continue <br /> Ito flow in a northwesterly to northerly.direction. <br /> • TPH-g was detected in ground water samples'from monitoring wells MW-1 and MW-4; <br /> located down=gradient from the former UST excavation.Concentrations of dissolved TPH-g. <br /> I decreased this quarter in well MW-l; but decreased in well MW-4. <br /> .J.y BTEX compounds were detected in the ground water samples collected from MW-1•and 1 <br /> t S� MW-4. <br /> • 1;2-DCA was not detected in the ground water samples this quarter. . j <br /> •` MTBE was-not detected'in the water samples collectedfrom,the site for the fW consecutive <br /> quarter. ; <br /> r <br /> 5A. -RECOMMENDATIONSf <br /> Based on,this'andprevious site investigatioris, AGE recommends continued quarterly monitoririg <br /> of the well network. The third,quarter 2005 monitoring event was performed in September.2005.' <br /> G.O.. : LI'MITATIONS' 7 <br /> Our professional services were performed using that degree of care and skill ordinarily exercised by <br /> environmental consultants practicing in this or similar localities. The findings were based upon <br /> analytical 'results provided by an.independent laboratory..:Evaluations of the hydrogeologic <br /> conditionsat the site for the .purpose of this investigation are'made from a limited number:of <br /> Advaneed'GeoEnvironmentel,Inc.. <br />
