� 9 <br /> m <br /> Osie <br /> 2.3 Analysis of Samples <br /> Two soil and five grab-groundwater samples were submitted for analysis to McCampbell <br /> Analytical Inc. (MAI)of Pittsburg, California. In addition, five soil vapor samples were submitted <br /> for analysis to Torrent Laboratory, Inc. (Torrent)of Milpitas, California. Both MAI and Torrent are <br /> State of California-certified analytical laboratories. The analytical program included the following <br /> United States Environmental Protection Agency(USEPA) Methods as summarized below: <br /> IDENTIFIED RECs SOIL BORINGS PROPOSED ANALYSES <br /> 1 Soil Sample(13V-2 @ 27.5') <br /> Historical On-site VOCs: USEPA Method 8260B <br /> Filling/Service Station TPH Multiscan: USEPA Method 8015M <br /> (3 and 3'/z West Harding BV-1 and BV-2 <br /> Way/1501 North Center 2 Grab-Groundwater Samples(1 sample from each <br /> Street) boring) <br /> VOCs: USEPA Method 8260B <br /> TPH Multiscan: USEPA Method 8015M <br /> 1 Grab-Groundwater Sample <br /> Southeast Adjoining VOCs: USEPA Method 8260B <br /> Filling Station BV-3 TPH Multiscan: USEPA Method 8015M <br /> (16 East Harding Way) <br /> 1 Soil Sample(13V-4 @ 27.5') <br /> VOCs: USEPA Method 8260B <br /> Southwestern and TPH Multiscan: USEPA Method 8015M <br /> Upgradient Adjoining BV-4 through BV-6 2 Grab-Groundwater Samples(13V-4&BV-5) <br /> Dry Cleaner <br /> (48 West Harding Way) VOCs: USEPA Method 8260B <br /> 5 Soil Vapor Samples(13V-4, BV-5,&BV-6) <br /> VOCs: USEPA Method TO-15 <br /> Historic Nearby BV-3 through BV-6 See analyses described above <br /> Properties <br /> (1)USEPA=United States Environmental Protection Agency <br /> (2)TPH=Total petroleum hydrocarbons <br /> (3)VOCs=Volatile organic compounds <br /> A soil vapor sample at BV-6-5' could not be analyzed as a sufficient volume of sample was not <br /> obtained due to the low-flow sampling conditions encountered at that soil vapor sample location. <br /> Also, BV-6 was terminated at a total depth of 12 feet bgs and no groundwater was encountered at <br /> this depth; therefore, the proposed grab-groundwater sample at this location could not be <br /> collected. <br /> 6 Project Number 99008-008321.03 <br />
