I <br />' 26 March 2001 <br /> • AGE-NC Project No 95-0130 <br /> Page 2 of 5 <br /> 2 2 GROUND WATER SAMPLING <br /> Following well purging, ground water levels In monitoring wells MW-1 through MW-5, VW-1B, <br />' VW-1C, VW-2A and VW-3A were allowed to achieve a minimum of 80 percent recharge prior to <br /> sample collection Ground water samples were collected from the purged wells utilizing new, <br /> disposable polyethylene bailers and three 40-m1 EPA-approved VOA vials containing 0 5 ml 18% <br />' hydrochloric acid as a sample preservative Care was taken to ensure that visible air bubbles were <br /> not present in the vials after filling and capping Ground water sample containers were labeled with <br /> the well designation, date, time, and sampler's initials <br /> 2 3 LABORATORY ANALYSIS OF GROUND WATER SAMPLES <br />' Each ground water sample was logged on a chain-of-custody form, placed in a chilled container and <br /> transported to a California Department of Health Services (DHS)-certified laboratory for analysis <br /> I for <br /> • • Total petroleum hydrocarbons quantified as gasoline (TPH-g ) by EPA Methods 5030/8015 <br /> Modified and 3550/8015 Modified, <br /> • Volatile aromatic compounds - benzene, toluene, ethylbenzene and xylene (BTEX) and <br /> methyl-tertiary butyl ether (MTBE) by EPA Method 8020, <br /> • Fuel oxygenated compounds -methanol, ethanol, tertiary butanol (TBA), di-isopropyl ether <br /> (DIPE), ethyl tert butyl ether (ETBE), tert amyl methyl ether(TAME) and MTBE by EPA <br /> Method 8260 Modified, and <br /> • 1,2-dichloroethane (1,2-DCA) and ethylene dlbromide (EBD) by EPA Method 8260 <br /> Modified <br /> 3.0. FINDINGS <br />' Ground water elevation, flow direction and gradient were determined from field data collected on <br /> 27 October 2000, the contaminant impact to ground water was assessed from the ground water <br /> laboratory data <br /> 3 1 RELATIVE GROUND WATER ELEVATION AND GRADIENT <br /> IThe depths to ground water in wells MW-1 through MW-5, VW-1B, VW-1C, VW-2A and VW-3A <br /> were measured between 38 39 and 39 61 feet below the tops of well casings, ground water elevations <br /> Advanced GeoEnvironmental,Inc <br />
