25 August 1998 <br /> AGE-NC Project No. 98-0481 <br /> Page 6 of 7 <br /> with the findings and recommendations. <br /> 3.4. SAMPLING, REMOVAL, AND DISPOSAL OF SOIL STOCKPILES <br /> During the tank removal activities, several of the soil stockpiles had detectable concentrations of <br /> BTEX, TPH-d, TPH-g, and LUFT metals. Approximately 14 cubic yards of soil were reportedly <br /> impacted. Composite soil samples will be collected from the soil stockpiles that were previously <br /> reported to be impacted with petroleum hydrocarbon compounds. Composite soil samples will be <br /> collected for confirmation analysis and potential waste profiling and will be analyzed for the full list <br /> of analytes presented in Section 3.1. Based on the results of the proposed confirmation soil sample <br /> analysis, disposition of the excavated soil will be determined. <br /> 3.5. 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 and applicable recommendations <br /> will be included in the report. The report will be in a format acceptable to the PHS-EHD and the <br /> CVRWQCB, and will be reviewed and signed by a Califomia 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. Procedures for the advancement of probe borings, soil sampling, ground water <br /> sampling, equipment decontamination and sample shipment are outlined below. <br /> 4.1. PROBE BORING ADVANCEMENT <br /> Probe borings will be advanced using AGE's van-mounted Geoprobe 5400 direct-push probing unit <br /> equipped with 1.25-inch probing rods. The Geoprobe advances soil probe borings using a hydraulic <br /> or pneumatic hammer to drive soil and ground water sampling tools to specified depths. <br /> 4.2. SOIL SAMPLING PROCEDURES <br /> . Soil samples will be collected using Geoprobe push-driven 2-inch diameter discrete and continuous <br /> Advanced GeoEnvironmental,Inc. <br />
