03 November 2000 <br /> AGE-NC Project No 98-0511 <br /> Page 2 of 3 <br />' hydrochloric acid as a sample preservative After collection, the samples were properly labeled, <br /> placed in a chilled container and transported under chain-of-custody to McCambell Analytical <br /> Laboratories, Inc , and were analyzed for <br />' • Total petroleum hydrocarbons quantified as gasoline (TPH-g) in accordance with EPA <br /> p Y <br />' Methods 5030 and 8015m, <br /> • Volatile aromatic hydrocarbons benzene, toluene, ethylbenzene and total xylenes (BTEX) <br /> with methyl tertiary-butyl ether(MTBE) in accordance with EPA Method 60218020, and <br />' Fuel oxygenates di-isopropyl ether (DIPE), ethyl tertiary-butyl ether (ETBE), MTBE, <br /> tertiary-amyl methyl ether (TAME) and tertiary butanol (TBA) in accordance with EPA <br />' Method 8260 Modified <br />' 3.0. FINDINGS <br /> Ground water elevation and flow direction were calculated from field data, hydrocarbon-impact to <br />' ground water was inferred from laboratory analysis of the ground water samples <br />' 3 1 GROUND WATER GRADIENT AND FLOW DIRECTION <br />' The elevation of ground water in each well was calculated by subtracting the depth to ground water <br /> from the surveyed casing elevations (Table 1) Depths to ground water ranged from 13 64 feet to <br /> 14 07 feet below the tops of the well casings Ground water elevations at the site ranged from 4 25 <br />' feet in MW-3 to 4 59 feet in MW-2 relative to mean sea level The ground water gradient was <br /> calculated to be 0 0036 ft/ft directed N 45'W <br />' 3 2 ANALYTICAL RESULTS OF WATER SAMPLES <br />' TPH-g and the four BTEX compounds were detected in the ground water sample collected from <br /> MW-1 at concentrations of 11,000 micrograms per liter (ggd), 460 �ig/l, 550 µg/1, 340 gg/1 and <br /> 2,000 gg/l, respectively TPH-g was detected in the ground water sample collected from MW-3 at <br />' a concentration of 57 µg/l <br /> MTBE was detected by EPA Method 8020 in the ground water sample collected from MW-3 at a <br />' concentration of 20 µg/1 MTBE was detected by EPA Method 8260 in the ground water samples <br /> collected from MW-3 at a concentrations of 22 gg/l No other fuel oxygenated compounds were <br />' detected above laboratory reporting limits <br /> Advanced GeoEnvironmentai,Inc <br />
