13 August 1997 <br /> AGE-NC Project No. 96-0264 <br /> Page 2 of 4 <br /> 4.0. SCOPE OF WORK <br /> 4.1. PROBING AND SAMPLING <br /> AGE proposes to advance a minimum of six soil probe borings at the site. The subsurface <br /> investigation at the site is necessary to determine if soil and/or ground water at the site has been <br /> impacted by hydrocarbons. \0 :,-,O�A 6-41G <br /> Probe borings will be advanced to depths of approximately 15 feet below surface grade (bsg) using <br /> direct push technology(DPT). Four probe boring will be advanced near the oil water separator and <br /> two probe borings will be established west and east of the edges of the surface water evaporation <br /> pond on the site. All probe borings will be advanced using a Geoprobe probing unit equipped with <br /> 1.25-inch probe rods. The proposed probe boring locations are illustrated in Figure 2. <br /> Soil samples will be collected at five-foot intervals, beginning at five feet bsg using a Geoprobe <br /> sampler and associated six inch by 1.125 inch diameter brass sleeves. Upon sample retrieval, the <br /> second brass sleeve will be preserved. The ends of the sleeve will be immediately covered with <br /> Teflon tape or aluminum sheets,capped and sealed with tape. Each soil sample will be labeled with <br /> the following: boring location, depth,time, date and sampler's initials. After collection, samples will <br /> be stored in a chilled container, under ice and transported to a State-certified laboratory. <br /> 4.2. EQUIPMENT DECONTAMINATION <br /> All sampling tools used for sample collection will be thoroughly rinsed with clean water after <br /> washing with a solution of Alconox. All Geoprobe rods are cleaned prior to advancement in each <br /> probing location. <br /> 4.3. LABORATORY ANALYSIS <br /> Selected soil samples will be analyzed for total petroleum hydrocarbons(TPH-all),volatile aromatic <br /> hydrocarbons(benzene,toluene, ethylbenzene and total xylenes: BTE&X) and methyl tertiary butyl <br /> ether(MTBE) in accordance with EPA methods 8015/5030, 820/602 and 8020/602, respectively. <br /> Laboratory reports of soil analysis, testing methods, laboratory quality assurance/quality control <br /> (QA/QC) reports, and sample chain-of-custody documentation will be presented in a report with the <br /> findings and recommendations. <br /> Advanced GeoEnN ironmental,Inc. <br /> r.: <br />
