12 April 1996 <br /> AGE-NC Project No. 95-0137 <br /> Page 3 of 6 <br /> 3.3. LABORATORY ANALYSIS <br /> Selected soil and ground water samples will be analyzed for TPH-g, TPH-d and BTE&X in <br /> accordance with EPA methods 801515030, 8015/5030 and 80201602, respectively. Laboratory <br /> reports of both soil and ground water analyses, testing methods, laboratory duality assurance/quality <br /> control(QA/QC) reports, and sample chain of custody documentation will be presented in a report <br /> with the findings and 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 performer.: <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 Institut-, 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. Boring locations will be marred at least 48 hours in advance for an Underground Service <br /> Alert (USA) check of underground utilities or pipes, <br /> 4. Advance five probings using a van-mounted Geoprobe equipped with a 1.125-inch diameter <br /> probe rods. Probings will be advanced to depths of 20 to 25 feet bsg. Probing locations are <br /> 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 10, 15 and 20 feet bsg, using a Geoprobe soil sampler <br /> assembly loaded vvith pre-cleaned 1.125-inch by 6-inch brass sleeves. Selected probings may <br /> be continuously sampled. <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. Store the samples under ice and transport the samples in a chilled container to a State- <br /> certified laboratory for analysis. <br /> 9. Screen soil sample duplicates for the presence of volatile organics using a photo-ionization <br /> detector (PID) pyre-calibrated to isobutylene. <br />
