, k , 14 September 2004 . AGE-NC Project No 96-0235 Page 3;of 8 . r diameter (O D ) stainless steel bailer was lowered and utilized to extract a ground water sample Ground water samples were collected from dedicated bonngs at the following Intervals , r� CPT-01 was sampled between 77 and 81 feet bsg and between 93 5'and 97 5 feet bsg, , • CPT-02 was sampled between 114 and 118 feet bsg and between 137 and 141 feet bsg, • CPT-03 was sampled between 50 and 54 feet bsg, 74 and 78 feet bsg, 133 and 137 feet bsg and 176 and 180 feet bsg, t w • CPT-04 was sampled between 80 and 84 feet bsg and 166 and 170 feet bsg, and • � Soil boring CHB-01 was sampled between 78 and 82 feet bsg 22 ANALYTICAL METHODS Grab ground water samples were transported to Cal Tech Environmental Laboratories (CTEL), a DHS-certified laboratory, for analysis Samples were analyzed for E • • Total petroleum hydrocarbons quantified as gasoline (TPH-g) and as diesel (TPH-d) in accordance with EPA Method 8015M, • Benzene,toluene, ethylbenzene and total xylenes (BTEX) in accordance with EPA Method 8260B, i J J Fuel additives including - di-isopropyl ether (DIPE), ethyl tertiary-butyl ether (ETBE), methyl tertiary-butyl ether (MTBE), tertiary-amyl methyl ether (TAME) tertiary-butyl alcohol (TBA), ethanol, methanol, 1,2-dibromoethane (EDB) and 1,2-dichloroethane (1,2- DCA) in accordance with EPA Method 8260B Ground water sample CPT-01193 5-97 5 was not arialyzed for,TPH-d, adequate sample volume to fill a 1-liter amber bottle could not be obtained from the boring _ I , 3.0 FINDINGS , Soil stratigraphy was determined from field data collected,during the June 2004 investigations, supplemented with boring logs recorded during previous investigations The contaminant Impact to - F , ground water was 'assessed from the laboratory analytical data collected during June 2004 investigations Advanced GeoEnviron mental,Inc i
