GRAB GROUND WATER SAMPLE COLLECTION AND ANALYSIS <br /> Grab ground water samples will be collected if ground water is encountered during the boring <br /> process using a Geoprobe water sampling assembly. Samples will be collected into 40-m1 volatile <br /> organic analysis (VOA) vials and 1-liter amber bottles as appropriate for the required analyses. <br /> Ground water sample collection procedures are presented in Section 4.1.2. Ground water samples <br /> will be analyzed by a DHS-certified laboratory for: <br /> • TPH-d by EPA Method 8015 Modified; <br /> • BTEX and MTBE by EPA Method 8020. <br /> Laboratory reports for ground water analyses, testing methods, laboratory quality 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 /> 3.4. REPORT PREPARATION <br /> Upon completion of field work and receipt of final laboratory analysis, a report will be prepared <br /> presenting the findings of the investigation. The report will include a description of the work <br /> performed and results of the sampling and analysis. Conclusions, applicable recommendations,maps <br /> and cross-sections will be included in the report. The report will be in a format acceptable to the <br /> PHS-EHD, and will be reviewed and signed by a California Registered Geologist. <br /> 4.0. FIELD PROCEDURES <br /> All field procedures will be overseen by an AGE representative under the supervision of a California <br /> Registered Geologist.
