26 February 1998 <br /> AGE-NC Project No. 97-0394 <br /> Page 2 of 4 <br /> 3.0. SCOPE OF WORK <br /> 3.1. PROBING AND SAMPLING <br /> A subsurface investigation at the site is necessary to investigate if an unauthorized release of <br /> petroleum hydrocarbons or chlorinated chemicals related to the possible former use of underground <br /> storage tank(s) (USTs)at the site and possible releases from chemical storage area and on oil/water <br /> separator adjacent to the property. The scope of work is to advance five (5) soil probe borings, <br /> utilizing direct push technology (DPT). Probe borings will be advanced to depths of approximately <br /> 15 to 25 feet below surface grade (bsg), using direct push technology (DPT). Proposed probe boring <br /> locations are illustrated in Figure 2. <br /> Soil samples will be collected at five-foot intervals using a Geoprobe sampler and four brass sleeves. <br /> Upon sample retrieval, the second brass sleeve will be removed from the sampler. The ends of the <br /> sleeve will be immediately covered with Teflon tape or aluminum sheets, capped and sealed with <br /> tape. Each sample will be placed in a chilled container for transportation to a state-certified <br /> laboratory. Each sample sleeve will be labeled with the following: boring location,depth,time,date <br /> and sampler's initials. After collection, samples will be stored in a chilled container and transported <br /> to a state-certified laboratory. <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 Geoprobe rods are cleaned prior to advancement <br /> in each probing location. <br /> 3.3. LABORATORY ANALYSIS <br /> Selected soil samples will be analyzed by the following EPA methods for the specified analytes and <br /> compounds: <br /> • EPA Method 8015 M for total petroleum hydrocarbons quantified as gasoline(TPH-g),EPA <br /> Method 8020 for volatile aromatic compounds (benzene, toluene, ethyl-benzene and total <br /> xylenes: BTE&X), <br /> • EPA Method 8010 for halogenated volatile organic hydrocarbons, <br /> • EPA Method 9040 for soil pH, <br /> Advanced GeoEnvironmental,Inc. <br />
