LABORATORY ANALYSIS <br /> Selected soil and groundwater samples Will-be analyzed for TPH-g, BTE&X and methyl tertiary, <br /> butyl ether (MTBE) in.accordance with-EPA methods.8015m/5030,. 8020/602 and 8020/602, <br /> respectively. Laboratory reports of both soil and ground water analysis,testing methods, laboratory <br /> quality assurance/quality control (QA/QC)reports, and sample chain of custody documentation will <br /> be presented in a report 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 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. Probe boring locations will bemarked at least 72 hours in advance for an Underground <br /> Service Alert (USA) check of underground utilities or.pipes. <br /> 4. Advance soil probe boring_s using a van-mounted Geoprobe equipped with a 1.125-inch. <br /> diameter probe rods and a 1.125--inch diameter soil sampler. Probing borings will be <br /> advanced to depths of approximately 40 to 45 feet bsg.,; Probe boring locations are illustrated <br /> 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 1.125-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 he Unified.Soil Classification System. <br />
