i <br /> i M4PiGEPS GESIGNEPS'WNStRTRNTS <br /> Groundwater samples were collected from locations SB-1,,SB-2, and SB-3 from a Hydropunch <br /> Isampling device. The Hydropunch tip was pushed throughi the hollow stem auger to a depth of <br /> 70 feet b s. The Hydropunch was then retracted so that 3,feet of screen was exposed from 67 <br /> gP <br /> feet to 70 feet bgs. The groundwater sample was collected with a stainless steel bailer. <br /> Groundwater samples were collected in laboratory supplied sample bottles, placed in plastic <br /> sealable bags, placed in an insulated cooler on ice, and bogged on a chain of custody form. <br /> Samples for Volatile organic analysis were checked for air bubbles. Samples were delivered by <br /> the field geologist to American Environmental Network in Pleasant Hill, California for analysis. <br /> 2.3 ANALYTICAL METHODS <br /> Soil samples'l were submitted for analysis of TPH-G (Method 8015m) and benzene, toluene, <br /> ethylbenzene'# and total xylenes (BTEX, Method 8020). <br /> The groundwater sample collected at SB-1 was submitted for analysis of TPH-G (Method <br /> 8015m), oil and grease (Method 5520 B&F), BTEX (Method 8020), chlorinated hydrocarbons i <br /> (Method 8010), LUFT metals (Method 6010), polychlorinated biphenyls (PCBs, Method 8080), <br /> and for gasoline oxygenates (Method 8260). The gasoline oxygenates included t-butanol (TBA), <br /> methyl-t-butyl ether (MTBE), di-isopropyl ether (RIPE),,Iethyl-t-butyl ether (ETBE), and t- <br /> �r amylmethyl ether (TAME). Groundwater samples collected!;from SB-2 and SB-3 were submitted f <br /> for analysis of TPH-G (Method 8015m) and BTEX (Method 8020). <br /> Ir <br /> k <br /> 1 <br /> 1 <br /> 7 Nm.1997 <br /> L:\....\PEPBOYS\WESTLN.REP <br />
