12 February 1996 <br /> AGE-NC Project No. 95-0112 <br /> Page 2 of 3 <br /> approximately 25 feet east of MW-1. Proposed boring locations are illustrated on Figure 2. <br /> Each boring will be advanced utilizing a truck mounted, hollow stem drill rig and 8.25-inch hollow- <br /> stem augers. Soil samples will be collected at five-foot intervals beginning at 10 feet bsg using a <br /> California split-spoon sampler and brass sleeves. The sampler will be driven by dropping a 140- <br /> pound weight from a height of 30 inches. The number of blows required to drive each 6-inch length <br /> of the sampler (blow counts) are to be recorded on the boring logs by an AGE star geologist. <br /> Upon sample retrieval, the middle brass sleeve will be removed from the sampler. The ends of the <br /> sleeve will be immediately covered with Teflon sheets, sealed with plastic end caps, secured with tape- <br /> and <br /> apeand immediately placed in a chilled container for transportation to a State-certified laboratory. Each <br /> sample sleeve will be labeled with the following: boring location, depth, time, date and sampler's <br /> initials. <br /> 3.2. EQUIPMENT DECONTAMINATION <br /> All sampling tools and brass sleeves used for sample collection will be thoroughly rinsed with clean <br /> water after washing with a solution of Alconox. All hollow stem augers are steam-cleaned prior to <br /> advancement in each borehole. <br /> 3.3. LABORATORY ANALYSIS <br /> Selected soil samples will be analyzed for total petroleum hydrocarbons quantified as gasoline (TPH- <br /> g) and volatile aromatics (benzene, toluene, ethyl benzene, and xylenes: BTE&X) in accordance with <br /> EPA methods 8015m and 8020, respectively. Laboratory reports of both soil and ground water <br /> analyses, testing methods, laboratory quality assurance/quality control (Q:,��QC) reports, and sample <br /> chain of custody documentation will be presented in a report with the findings and recommendations. <br /> 4.0. PROCEDURES <br /> 4.1. DRILLING AND SAMPLING <br /> The following procedures will be performed for the drilling of each soil boring, <br /> L Notify the PHS-EHD at least 48 hours prior to the commencement of any work. <br /> 2. Drill each soil boring at the site to a depth of approximately 60 feet using a truck-mounted <br /> drill rig equipped with hollow-stem augers. Proposed boring locations are illustrated on <br />
