' 08 June 2002 AGE-NC Project No 98-0433 ' Page 4 of 8 ' After collection,the samples were labeled and placed in a chilled container for transportation under chain-of-custody to McCampbell Analytical Laboratories, a DHS-certified analytical laboratory Each sample was analyzed for ' 0 TPH-g and TPH-d in accordance with EPA Method 8015 Modified, ' a BTEX and MTBE in accordance with EPA Method 8020, and • The oxygenated fuel additives MTBE, TBA, DIPS, ETBE, TAME, ethanol and methanol in accordance with EPA Method 8260 Modified ' In addition, a ground water sample from the on-site domestic drinking water well (DW-1)was also collected and analyzed After the well pump was operated for one minute, a sample was collected from a dedicated sample tap The sample was placed into one 1-liter amber bottle lacking a sample preservative and into three chilled 40-m1 VOA vials containing 0 5 ml hydrochloric acid (18%) as a sample preservative . 3.0 FINDINGS Soil descriptions and ground water elevation and flow direction were determined from field data Hydrocarbon-impact to soil and ground water was inferred from laboratory analysis of the soil and ' ground water samples 3 1 SOIL DESCRIPTIONS Five soil samples were collected'from boring B17 Between 20 and 30 feet bsg, the soil consisted ' of gray and reddish brown,poorly graded fine sand At 35 feet bsg, the soil was identzfled as brown silt with clay The last sample collected, at 40 feet bsg, consisted of brown silty sand 1 3 2 FIELD EVIDENCE OF HYDROCARBON-IMPACTED SOIL ' The OVM detected organic vapor above background in all of the soil sample duplicates,the highest organic vapor concentrations detected were from samples B17-20 and B17-21 at 865 parts per ' million (ppm) and 281 ppm, respectively Additionally, a strong petroleum hydrocarbon-like odor was detected from samples B 17-20 and B 17-21,and a faint hydrocarbon-like odor was detected from sample B17-40 • ' Advanced CeoEnvironmental,Inc I
