1 <br /> 5.0 SCOPE OF WORK <br /> 5.1: Scheduling <br /> This task includes scheduling field personnel and equipment, locating underground utilities, <br /> and performing any other necessary field preparation and job start-up activities. <br /> 5.2: Advancing Six Soil Borings <br /> This task includes mobilization to the .site, advancing six soil borings, and collecting soil and <br /> groundwater samples. <br /> Six soil borings will be advanced to :depths of approximately 15 feet by Direct Push <br /> Technology (DPT). The proposed locations of these borings are shown on Figure 2. <br /> Additional borings may need to be completed depending upon field conditions during drilling <br /> in order to complete delineation of soil and groundwater contamination. Drilling will be <br /> conducted by a State-licensed (C57) drilling company. A field geologist will be present to log <br /> all drill cuttings and soil samples. Descriptions of soil types encountered and sample <br /> collection intervals will be recorded on boring logs. Soil samples will be collected at five foot <br /> intervals, field screened with a photo ionization detector. Samples will be collected in 7/8- <br /> inch diameter and 1-foot long brass -tubes using the Diedrich Drill ESP System, a dual-rod <br /> sampling technique which will enable collection of undisturbed soil samples at the desired <br /> depth. The tubes will be immediately sealed at each end using teflon tape and plastic end caps, <br /> labeled, and placed on ice. A temporary casing will be set in the open boring to allow for the <br /> collection of a groundwater sample. One soil sample and one groundwater sample from each <br /> boring will be submitted for laboratory analysis of TPHg and BTEX.. <br /> Samples will be sent using chain-of-custody record to a State-certified laboratory for analysis <br /> of TPHg and BTEX by EPA methods 8015/8020, respectively. Following sample collection, <br /> each boring will be grouted to the ground surface with neat cement using tremie pipe. Any <br /> drill cuttings will be placed in 5-gallon buckets and stored on-site pending laboratory results. <br /> 5.3.- Report_Preparation <br /> A summary report will be prepared for submittal to PHS/EHD. The report will summarize <br /> field and laboratory procedures, contain all analytical data, and include recommendations for <br /> additional investigation, if necessary. <br /> w:195122\wP-GLOV.dm 3 <br /> SMTH <br />
