12 November 2010 AGE-NC Project No. 907-1587 Page 5 of 7 samples collected from the wells MW-1A, MW-113 and MW-213 at a maximum concentration of 13,000 pg/I. Additionally, TAME was detected in monitoring well MW-1A at a concentration of 8.9 pg/I; benzene was detected in wells MW-1A, MW-113, MW-2B and MW-3B at a maximum concentration of 410 pg/I; toluene was detected in wells MW-1A, MW-1 B and MW-213 at a maximum concentration of 43 pg/I; ethylbenzene was detected in wells MW-1A and MW-1B at a maximum concentration of 1,700 pg/I; and xylene was detected in wells MW-1A, MW-16, MW-2B and MW-3B at a maximum concentration of 971 pg/I. Other petroleum products or additives were not detected above laboratory reporting limits in any additionally analyzed soil or ground water samples collected during the July,August or October environmental events at the site. Analytical results of soil and ground water samples collected during the third and fourth quarters of 2010 are summarized in Table 1 and Table 2, respectively. The laboratory report (CTEL Project No. CT214-1008004, 1008075 and 1010063), chain of custody forms and the laboratory quality assurance/quality control(QA/QC)reports are included in Appendix F. Confirmation for the submitted laboratory electronic deliverable format (EDF) files to GeoTracker are 3308030128, 5607401549, 7796494483. 3.3 GROUND WATER ELEVATION, FLOW DIRECTION AND GRADIENT Ground water elevation, flow direction, and gradient were determined from field data collected on 08 October 2010. Hydrocarbon-impact to ground water was quantified by laboratory analytical data. At the time of the October 2010 sampling event: Hydrogeoloqic Zone HU1: 20 to 40 feet bsq Depth to ground water in the shallow ground water interval (20 to 40 feet bsg) was found at 20.28 feet (MW-1 A) below the top of the well casing (btoc). Ground water elevation at the water table was at 7.90 feet below North American Vertical Datum (NAVD88). Hydrogeoloqic Zone HU2: 55 to 60 feet bsq • Depths to ground water ranged between 21.92 feet (MW-1 B) below the tops of the well casings(btoc)and 23.00 feet(MW-3B) btoc(Table 1). Ground water elevations at the site ranged between 9.49 feet (MW-7) below North American Vertical Datum (NAVD88) and 10.95 feet (MW-4B) below NAVD88. • Utilizing site wells MW-1 B through MW-4B, ground water flow direction was inferred to be flowing north-northeast at an approximate hydraulic gradient of 0.01 foot per Advanced CeoEnvironmental,Inc.
