Apex proposes to collect five sidewall soil samples from the,excavation as shown on Figure 3. <br /> The five soil samples will be collected at ten feet bg, which is the soiUgroundwater interface. Two <br /> groundwater samples-will be collected from the excavation also. The groundwater samples will <br /> " be collected after the groundwater is removed from the excavation with the use of a vacuum <br /> truck. Apex will also collect soil stockpile samples (one sample per 50 cubicyards of soil <br /> stockpiled) for analysis. Based on 710 yards, this will be a maximum of 15 stockpile soil samples. <br /> All soil stockpile and excavation samples will be submitted, under chain-of-custody, to a <br /> state-certified,laboratory for analysis of: a) TPH, as gasoline; TPH, as diesel, by modified EPA <br /> j' Method-8015; and b)BTEX and MTBE by EPA Method 8020.' All excavated soil will be <br /> temporarily stockpiled on site, under and on plastic sheeting, pending receipt of the analytical <br /> results." <br /> All groundwater which enters the proposed excavation will be pumped out with the use of a . <br /> vacuum truck. Two groundwater samples will be collected after groundwater recharges into the <br /> excavation. The removed water will then be properly disposed of by a licensed hauler. After the <br /> r. groundwater-is removed from the excavation, two groundwater samples will be collected from the <br /> f groundwater that flows into the excavation. <br /> k. During the proposed excavation, groundwater monitoring well MWA, vapor extraction well <br /> VEW-I,.and air sparge well AS-1- will be removed with the use of the excavator(Figure 2). <br /> REMARKS AND SIGNATURES <br /> The interpretations and/or conclusions contained.in this report represent the professional.opinions <br /> of Apex Envirotech, Inc.
