Libbey Owens Ford Co. <br /> Geoprobe Investigation Work Plan <br /> November 5, 1996 <br /> Page-4- <br /> groundwater sample is reached, the sample chamber will be opened by pulling back on the body of the <br /> ' sampler, exposing the screen. When the screen is full, a small diameter polyethylene tube will be <br /> Iowered into the push rod and a groundwater sample will be pumped to the ground surface using a <br /> ' peristaltic pump. The sample tubing will be replaced with new tubing prior to sampling each <br /> borehole. <br /> The groundwater samples will be gently collected from the pump discharge. The samples will <br /> be inspected for free product, petroleum odor, and sheen. Each sample will consist of two (2) 40-m1 <br /> ' glass volatile organic analyses (VOA) vials, and one (1) 1-liter amber glass bottle. The sample <br /> containers will be sealed, labeled, and placed in a cooler chilled with ice for delivery under chain-of- <br /> custody procedures to GeoAnalytical Laboratories, in Modesto, California for analyses. <br /> t2.3 Chemical Analysis <br /> The soil and groundwater samples retained for chemical analysis will be analyzed for benzene, <br /> itoluene, ethyl benzene, and total xylenes (BTEX) by EPA Method 8020 (602 for water), and for total <br /> extractable petroleum hydrocarbons quantified as diesel, kerosene, and motor oil (TEPH) by Method <br /> ' 3550/LUFT (3510 for water). The analytical methods and analytical detection limits are presented <br /> below in Table 1. <br /> TABLE 1 <br /> Analytical Methods <br /> CONSTITUENT METHOD DETECTION LIMIT <br /> Soil <br /> BTEX 8020 5.0 µg/kg (BTEX) <br /> ' TEPH 3550/LUFT 5.0 mg/kg (diesel) <br /> 5.0 mg/kg(kerosene) <br /> 50.0 mg/kg (motor oil) <br /> ' Groundwater <br /> BTEX 602 0.3 µg/1 (BTB) <br /> 0.6 µg11 (X) <br /> ' TEPH 3510/LUFT 0.05 mg/i (diesel) <br /> 0.05 mg/1 (kerosene) <br /> 0.5 (motor oil) <br /> 1 <br /> 1 <br /> ' �� CONDOR <br />
