08 January 1996 <br /> AGE-NC Project No, 95-0105 <br /> Page 3 of 6 <br /> AGE will advance probings to depths of approximately S feet below ground surface (bsg) using direct <br /> push technology (DPT). Proposed probing locations are illustrated in Figure 2. <br /> Soil samples will be collected continuously using a Geoprobe sampler and four brass sleeves. Upon <br /> sample retrieval, the second brass sleeve will be removed from the sampler. The ends of the sleeve <br /> will be immediately covered with Teflon tape or aluminum sheets, capped and sealed with tape. Each <br /> sample will be 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 /> Grab ground water samples will be collected from at least four of the probings. Ground :rater <br /> samples will be collected using a Geoprobe water sampling assembly. After collection, samples will <br /> be stored in a chilled container, under ice and transported to a State-certified laboratory. <br /> 3.2. INSTALLATION OF GROUND WATER MONITORING WELLS <br /> Presently, no monitoring wells at the site are immediately down-gradient of the former UST <br /> excavation. The PHS-EHD is requiring the installation of at least one down-gradient monitoring well <br /> at the site. The Iocation(s) and number of wells to be installed will be based upon the results of the <br /> probing investigation. Upon determination of the locations and number of wells, an addendum will <br /> be completed depicting proposed locations for the wells. <br /> 3.3. EQUMMENT 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 /> 3.4. LABORATORY ANALYSIS <br /> r <br /> Selected soil and ground water samples will be analyzed for TPH-g and BTE&X in accordance with <br /> EPA methods 8015/5030 and 80201602, respectively. Laboratory reports of both soil and ground <br /> water analyses, testing methods, laboratory quality assurance/quality control (QA/QC) reports, and <br /> sample chain of custody documentation will be presented in a report with the findings and <br /> recommendations. <br />
