..r <br /> 12 December 1995 <br /> AGE-NC Project No. 95-0184 <br /> Page 3 of 6 <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 will be steam-cleaned prior <br /> to advancement in each borehole. <br /> 3.3. LABORATORY ANALYSIS <br /> Selected soil and ground water samples will be analyzed for total petroleum hydrocarbons quantified <br /> as gasoline and diesel (TPH-g and TPH-d) and volatile aromatics (benzene, toluene, ethylbenzene, <br /> and xylenes: BTE&JQ in accordance with EPA methods 8015/5030 and 8020/602, respectively. <br /> Additionally, several samples will undergo physicochemical and microbiological analysis to determine <br /> bioremediation feasibility. <br /> Laboratory reports of both soil and ground water analyses, testing methods, laboratory quality <br /> assurance/quality control (QA/QC) reports, and sample chain-of-custody documentation will be <br /> 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 borings and well completion: <br /> 1. Notify the PHS/EHD 48 hours prior to the commencement of any work. <br /> 2. Drill ten soil borings at the site. All borings will be drilled using a truck-mounted drill rig <br /> equipped with hollow-stem augers. Proposed boring locations are depicted on Figure 2. <br /> 3. Boring VW-1 will be drilled near the southeast corner of tank A and advanced to a depth of <br /> approximately 55 feet. Boring VW-2 will be placed approximately 8 feet northeast of MW-2 <br /> and advanced to a depth of approximately 55 feet. Boring VW-3 drilled approximately 20 feet <br /> east of tank A, drilled at a 30° angle toward the north and advanced to a vertical depth of <br /> approximately 55 feet. Boring VW-4 will be drilled approximately 7 feet south of MW-1, <br /> drilled at a 30° angle toward the east and advanced to a depth of approximately 55 feet. <br /> 4. Boring MW-5 will be drilled in the sidewalk 20 feet northwest of tank A and advanced to a <br /> depth of approximately 62 feet. Boring MW-6 will be drilled inside the building at 308 North <br /> Grant Street approximately 20 feet north of tank B and advanced to a depth of approximately <br /> 62 feet. <br />
