LABORATORY ANALYSIS _ <br /> Selected soil and ground water samples will be analyzed for TPH-g and BTE&X in accordance with <br /> EPA methods 8015m/5030 and 8020/602, respectively. Laboratory reports of both soil and round <br /> and <br /> water analyses, testing methods, laboratory quality assurance/quality control (QA/QC) reports, <br /> sample chain of custody documentation will be presented in a report with the findings and <br /> recommendations. <br /> 4.0. PROCEDURES <br /> 4.1.. COLLECTION OF SOIL AND GROUND WATER SAMPLES <br /> For the collection of soil and ground water samples, the following procedures will be performed: <br /> 1. Prepare a site health and safety plan in accordance with Occupational Safety and Health <br /> Guidance Manual for Hazardous Waste Site Activities (Prepared by National Institute for <br /> Occupational Safety and Health Administration, U.S. Coast Guard and U.S. Environmental <br /> Protection Agency, 1985). <br /> 2. Notify the PHS-EhD 48 hours prior to commencement of any work, while securing proper <br /> city/county soil boring permits. <br /> 3. Probing locations will be marked at least 72 hours in advance for an Underground Service <br /> Alert (USA) check of underground utilities or pipes. <br /> 4. Install six probings, using a van-mounted Geoprobe equipped with a 1.125-inch diameter <br /> probe rods and a 1.5-inch diameter soil sampler. Probings will be advanced to depths of <br /> approximately 35 to 40 feet. Probing locations are illustrated on Figure 2. <br /> 5. Decontaminate sampling equipment in an Alconox solution and rinse twice with water prior <br /> to each sampling run. <br /> 6. Obtain discrete soil samples at five foot intervals using a Geoprobe soil sampling assembly <br /> loaded with four pre-cleaned l.125-inch by 6-inch brass sleeves. <br /> 7. Preserve soil in the second brass sleeve by covering both ends with Teflon sheets, capping, <br /> and sealing with tape. Label and log samples on a chain-of-custody form. <br /> 8. Screen soil sample duplicates for the presence of volatile organics using a photo-ionization <br /> detector (PID) pre-calibrated to isobutylene. <br /> 9. Log borings in accordance with the Unified Soil Classification System. <br />
