r _ S 18 July 2005 , {M' AGE-NC Project No. 95-0106 I' Page,3-of 4' , F .1,2-DCA was detected at concentration of 2.7 pg/l in the sample collected from well MW-4. No additional analytes were detected at or above,laboratory reporting limits in wells MW-.i and `'MW=4. No analytes-were detected at or"above laboratory reporting limits in well's MW-2; MW_3,, ' MW-5, MW-6 u er MW-6 (lower) and MW77. Analytical results of ground water samples are summarized in Table 2. The laboratory report (CTEL Project No: CT214=0412127), quality assurance/quality control'(QAIQC)reports and chain of custody forms are included in Appendix C. . Documents confirming the upload of laboratory electronic deliverable format(EDF)files and depth' to water measurements to GeoTracker are included in Appendix D. 4:0. '-SUMMARY AND CONCLUSIONS = The followingconclusions were drawn from the,results of the site investigation: , ' J The.,ground water flow direction was generally northward on 16 December 2004,at gradients ranging between 0.003 ft/ft and 0.005 ft/R. Ground water elevations increased slightly but continue to flow in a northerly.direction. f '.� TPH-g was detected in ground water samples from monitoring well 'MW-4, located down-gradient off site from the farmer UST excavation.Concentrations of dissolved-TPH-g ' decreased this quarter to non=detect in well MW-1 while increasing in well MW-4. ,- BTEX compounds were detected in the ground water sample's collected from MW-i and MW-4. ' 1,2-DCA was detected this quarter in the ground water sample collected from well.MW-4. MTBE was not detected in the water samples collected from the site for the third consecutive '• quarter.. 5.0: ' RECOMMENDATIONS :r ' Based ori.this and-previous site investigations, AGE recommends continued quarterly monitoring of the.well network. The first.quarter 2005 monitoring event was performed.in March 2005. ; Advanced Geo Environmental,Inc.
