11 August 2008 <br />AGE -NC Project No. 07-1569 <br />Page 3 of 5 <br />reports, were included in the AGE -prepared Glass Limits Soil Excavation Report, dated 07 March <br />2008. <br />3.0. SCOPE OF WORK <br />AGE proposes to advance four soil borings in the former glass disposal area for collection of grab <br />ground water samples. The investigation will include the following tasks: <br />• Permitting and pre -field work activities; <br />• Grab ground water and/or soil sample collection and analysis; <br />• Report preparation <br />The site assessment tasks are discussed below. <br />3.1. PRE -FIELD WORK TASKS <br />A health and safety plan will be prepared in accordance with the Occupational Safety and Health <br />Guidance Manual for Hazardous Waste Site Activities (National Institute for Occupational Safety <br />and Health Administration, U.S. Coast Guard and U.S. Environmental Protection Agency, 1985). <br />Prior to mobilization, the area of excavation will be clearly marked, and a utility clearance obtained <br />through Underground Service Alert. <br />3.2. GRAB GROUND WATER SAMPLE COLLECTION AND ANALYSIS <br />AGE proposes to advance four soil probe borings using direct push technology in the former glass <br />disposal area. The borings will be advanced to approximately 20 feet bsg. A grab ground water <br />sample will be collected from each boring using a Geoprobe water sampling assembly. Samples will <br />be collected into respective 40-m1 volatile organic analysis (VOA) vials, and 1 -liter amber bottles <br />as appropriate for the required analyses, both without preservative; ground water sample collection <br />procedures are presented in Section 4.1. Ground water samples may be analyzed by a State of <br />California Department of Public Health (CDPH)-certified laboratory for some or all of the following <br />consituents: <br />• Total petroleum hydrocarbons quantified as gasoline (TPH-g), total petroleum hydrocarbons <br />as diesel (TPH-d) in accordance with EPA Method 8015M; and <br />• Volatile organic compounds, including benzene, toluene, ethylbenzene, and xylenes (BTEX), <br />Advanced GeoEnvironmentai, Inc. <br />
