SCOPE OF WORK <br /> AGE proposes to collect soil and grab ground water samples to determine if petroleum hydrocarbon- <br /> impacted soil and/or ground water is present beneath the site. The preliminary site assessment will <br /> include the following tasks: <br /> • Permitting and pre-field work activities; <br /> • Soil and grab ground water sample collection and analysis; and <br /> • Report preparation <br /> 3.1. PRE-FIELD WORK TASKS <br /> An updated health and safety plan will be prepared in accordance with Occupational Safety and <br /> Health Guidance Manual for Hazardous Waste Site Activities (National Institute for Occupational <br /> Safety and Health Administration, U.S. Coast Guard and U.S. Environmental Protection Agency, <br /> 1985). Prior to mobilization, the boring location will be clearly marked and a utility clearance <br /> obtained through Underground Service Alert. <br /> 3.2. SOIL AND GRAB GROUND WATER SAMPLE COLLECTION AND ANALYSIS <br /> AGE proposes to advance one soil probe boring using direct push technology in the north end of the <br /> former UST area to assess the vertical extent of petroleum hydrocarbon-impacted soil and potential <br /> hydrocarbon impact to ground water at the site. The boring will be advanced to a depth of 60 feet <br /> below surface grade (bsg) or until "first" ground water is encountered; the proposed probe boring <br /> location may be modified due to field observations. As the boring is advanced,'soil samples will be <br /> collected at 5-foot intervals beginning at 5 feet bsg and extending to the total depth of the probe <br /> boring. <br /> The proposed probe boring location is illustrated on Figure 2.Field procedures for the advancement <br /> of the boring and collection of soil and grab ground water samples are presented in Sections 4.1., <br /> 4.2., and 4.3., respectively. <br /> Selected soil and grab ground water samples from the probe boring will be submitted for laboratory <br /> analysis by a DHS-certified laboratory for one or more the following constituents: <br /> + TPH-g, TPH-d, and TPH-ho in accordance with EPA Method 8015M; and <br /> Advanced GeoEnvironmental,Inc. <br />
