r 16 March 2005 AGE-NC Project No. 97-0343 ' Page 2 of 3 • Total petroleum hydrocarbons quantified as gasoline (TPH-g) and as diesel (TPH-d) in accordance with EPA Method 8015 Modified; and • Benzene, toluene, ethylbenzene, and total xylenes (BTEX) and the fuel additives methyl- tertiary butyl ether (MTBE), di-isopropyl ether (DIPE), ethyl tertiary-butyl ether (ETBE), tertiary-amyl methyl ether (TAME), tertiary butyl alcohol (TBA), 1,2-dichloroethane (1,2-DCA), and 1,2-dibromoethane (EDB) in accordance with EPA Method 8260B. 1 ' 3.0. FINDINGS Ground water elevation in monitoring well MW-8 was determined from field data collected on ' 23 December 2004.Flow direction and gradient were unable to be determined because wells MW-1 through MW-7 were dry. The contaminant impact to ground water was quantified from laboratory analytical data. 1 3.1. GROUNDWATER GRADIENT AND FLOW DIRECTION At the time of the December 2004 sampling event, depth to ground water in well MW-8 was ' 62.61 feet below the top of the well casing; ground water elevation was calculated to be 34.55 feet below mean sea level (MSL), ground water level remained relatively stable between this and the previous quarterly monitoring event(Table 1). 1 3.2. ANALYTICAL RESULTS OF GROUND WATER SAMPLES No petroleum hydrocarbons were detected in the ground water sample from well MW-8. I The analytical results of the water sample collected in December 2004 are summarized in Table 2. The laboratory report (CTEL Project No. CT214-0412212), quality assurance/quality control (QA/QC)report,and chain of custody form are included in Appendix C. Documents confirming the ' upload of laboratory electronic deliverable format (EDF) files and depth to ground water measurements to GeoTracker are included in Appendix D. 4.0. SUMMARY AND CONCLUSIONS IBased on the data collected from the site, AGE finds: • Advanced GeoEnvironmental,Inc.
