2.1.1 Hand Auger Soil Sampling <br /> At each boring location, soil samples will be collected at depths of 2.5 and 5 feet bgs <br /> using a hand auger sampler lined with a 6-inch acrylic liner. Following soil sample <br /> collection, the liner will be removed from the hand-auger, the ends will be capped with <br /> plastic end caps, and the capped liner will be placed in an iced cooler. In addition, a <br /> portion of soil cuttings from just above each sample interval will be field screened with a <br /> photo ionization detector(PID) for the presence of volatile organic compounds(VOCs). <br /> Following field screenings, the acrylic liner from each sample will be uncapped and <br /> representative samples for gasoline range petroleum hydrocarbons (TPH-g) and gasoline <br /> range VOCs will be collected using a laboratory-supplied United States Environmental <br /> Protection Agency (USEPA) Method SW5035 field extraction kit. The liner will be <br /> recapped for submittal to the laboratory for diesel range petroleum hydrocarbon (TPH-d) <br /> and polynuclear aromatic hydrocarbons(PAHs)and, as required,total lead analysis. <br /> 2.1.2 Direct-push Soil Sampling <br /> Following completion of hand-auger sample collection, each boring will be advanced <br /> from 5 feet bgs to 10 feet bgs utilizing direct-push drilling techniques. In each boring, <br /> soil samples will be collected continuously using acrylic liners installed within the <br /> direct-push boring rods. Upon retrieval from the boring, the acrylic liners containing the <br /> soil samples will be cut into approximately two foot sections, labeled with the depth <br /> interval. A portion of each section will be immediately field-screened using a PID for the <br /> presence of VOCs. The PID will be calibrated to 100 ppm isobutylene (volatile <br /> hydrocarbons). PID results will be recorded in the site field logbook. Following field <br /> screening, the ends of each section will be capped with plastic end caps and placed in an <br /> iced cooler. <br /> The soil samples from 0.5 to 1 foot above the soil/water interface (7.5 to 10 feet bgs) <br /> from each direct-push boring will be submitted for laboratory analysis. Upon <br /> determining the appropriate sample interval based on soil saturation, the acrylic liner <br /> from 0.5 to 1 foot above the soil/water interface will be cut to approximately one foot in <br /> length, and representative samples for gasoline TPH-g and gasoline range VOCs will be <br /> collected using a laboratory-supplied USEPA Method SW5035 field extraction kit. The <br /> liner will be recapped for submittal to the laboratory for TPH-d and PAHs. <br /> 2.2 Hollow-Stem Auger Boring/Well Installation <br /> A California P.G. or a geologist working under the direct supervision of a California P.G. <br /> will direct a licensed California well installer, to advance up to 16 hollow-stem auger soil <br /> borings for the installation of monitoring wells (Figure 3). The wells will be installed <br /> Sampling and Analysis Plan-Final 5/18/2012 <br /> 2-2 <br />
