A 7 September 2001 <br /> AGE-NC Project No. 98-0468 <br /> Page.6 of 7 <br /> Four ground water samples will be submitted to California Department of Health Services (DHS)- <br /> certified laboratory to be analyzed for the following constituents: <br /> • Total petroleum hydrocarbons quantified as gasoline and diesel (TPH-g, TPH-d) in <br /> accordance with EPA Method 8015-Modified, <br /> • Volatile aromatic compounds -benzene, toluene, ethylbenzene, and total xylenes (BTEX) <br /> and methyl tertiary butyl ether(MTBE).in.accordance with EPA Method 8020, and <br /> • Oxygenated fuel additives -MTBE,tertiary butyl alcohol.(TBA), di-isopropyl ether(DIPE), <br /> ethyl tertiary butyl,ether(ETBE) and tertiary amyl methyl ether(TAME) in accordance with <br /> EPA Method 8260 Modified. <br /> Laboratory reports for soil analyses, testing methods, laboratory quality assurance/quality control <br /> (QA/QC) reports, and.sample chain of custody documentation will be-presented in a report.with <br /> findings and'recommendations. <br /> 3.3. REPORT PREPARATION <br /> Upon completion of field work and receipt of final laboratory analysis, a reportwill beprepared <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 and applicable recommendations <br /> will be included in the report. The quarterly report will be in a format acceptable to the PHS-EHD <br /> and CVRWQCB, and will be reviewed and signed by a California Registered Geologist. <br /> A.0. FIELD PROCEDURES <br /> All field procedures will be overseen by an AGE representative under the supervision of a California <br /> Registered Geologist. Procedures for the advancement of the soil probe boring, soil sampling, <br /> equipment decontamination, and sample shipment are outlined below. <br /> 4.1 PROBE BORING ADVANCEMENT <br /> The probe borings will be advanced using a van-mounted Geoprobe 5400 direct-push probing unit <br /> equipped with 1.25-inch probing rods. The Geoprobe advances probe borings using hydraulic <br /> pressure and/or a pneumatic hammer to drive ground water sampling tools to specified depths. <br /> Advanced GeoEnvironmental,Inc. <br />
