loop <br /> i . Site preparation will include well permit application and utility <br /> clearance . Monitoring well installation permits will be obtained <br /> from the SJC-EHD. SJC-EHD will be notified a minimum of 48 hours <br /> before monitoring well and hydropunch installation begins . The <br /> proposed boring and well locations will be screened using a <br /> magnetometer to assess the potential presence of underground <br /> �# utilities . Underground Services Alert-, will also be contacted to <br /> assist in utility locating activities prior to initiation of <br /> investigation activities . <br /> '. Boring SB-1 will be located adjacent to the conveyor and shredder <br /> machine; boring SB-2 will be located at the southwest corner of <br /> the two adjoining warehouses ; and boring SB-3 will be located <br /> adjacent to the UST excavation. Additionally, three groundwater <br /> samples will be collected from the three monitoring wells _ Well <br /> MW-1 will be located at the northern perimeter of the Site; well <br /> MW-2 will be located adjacent to and south of the UST excavation; <br /> and well MW-3 will be located at the eastern perimeter of the <br /> Site . The approximate locations of the borings and monitoring <br /> wells are shown in Figure 3 . <br /> 4.1 Borings <br /> Soil samples will be collected from borings SB-1, SB-2 , and SB-3 . <br /> Grab groundwater samples will be collected from borings SB-1 and <br /> SB-2 using a hydropunch. <br /> Soil samples will be collected from the borings by driving a <br /> California-type split spoon drive sampler ahead of the hollow- <br /> stem augers . Soil samples will be collected, starting from the <br /> existing ground surface, at every 5 feet, at any lithologic <br /> changes and areas of obvious contamination. A minimum of two <br /> soil samples will be collected at 5-foot intervals beneath areas <br /> of obvious contamination to establish the vertical extent of the <br /> impacted sediments . The soil samples will also be screened using <br /> a portable photoionization detector (PID) . <br /> Hollow diameter steel casing containing a perforated PVC screen <br /> at the bottom of the casing will be advanced approximately 2 feet <br /> below the first permeable zone . The casing will then be <br /> retracted approximately 4 feet to allow infiltration of <br /> groundwater. Grab groundwater samples will be collected by <br /> lowering a Teflon bailer through the hollow casing. Samples will <br /> be transferred into 1-liter amber glass jars . A field blank <br /> sample and duplicate will also be collected for quality control <br /> purposes . The samples will be stored in a chilled cooler for <br /> delivery to the laboratory. Strict chain-of-custody protocols <br /> will be followed in all phases of sample handling. <br /> 3 <br />
