(QA/QC) reports, and-sample chain of custody documentation will Abe presented in a report with <br /> findings and recommendations. <br /> 3.3. GROUND WATER SAMPLE COLLECTION AND ANALYSIS <br /> # <br /> During the soil assessment field activities a p <br /> �. g ground water sample will be collected from the soil <br /> boring and ,submitted for laboratory analysis. Ground water sample collection procedures are <br /> presented in Section 4.2. <br /> Groundwater samples will be analyzed by"a State of California DHS-certified laboratory for the <br /> ( following constituents: - <br /> • TPH-g and TPH=d by EPA Method 8015 Modified/5030 and 8015 Modified/3550, <br /> respectively; <br /> • BTEX.and MTBE by EPA Method 8020;" <br /> • Oxygenating compounds including MTBE, TBA, DIPE, ETBE, 'TAME, ethanol and <br /> methanol by EPA Method 8260; and <br /> 1,2-DCA and EDB by EPA Method 8260. <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 /> t 3.4. MONITORING WELL INSTALLATION AND SAMPLING <br /> If the results of the initial soil and ground water assessment activities indicate significant petroleum <br /> hydrocarbon impact to ground water;up to three ground water monitoring wells will be installed at <br /> la. the site. Prior to installation of ground water monitoring wells;proposed locations for monitoring <br /> . i wells will be submitted to the PHS-EHD for approval. The proposed monitoring wells will provide <br /> Advanced GeoEnvironmental,Inc. <br /> ...fart <br />
