Soluble <br /> Threshold Limit Concentration may additionally be analyzed for metals. <br /> • Dioxin and Furan by EPA Method E1613 and SW8290. <br /> Laboratory reports for analyses, testing methods, laboratory quality assurance/quality <br /> control (QA/QC) reports, and sample chain-of-custody documentation will be presented <br /> in a report with the findings and recommendations. <br /> FILEDPROCEDURES <br /> All field procedures will be overseen by an AGE representative working under the <br /> supervision of a California Professional Geologist. Procedures for advancing soil probe <br /> borings, collection and analysis of soil and water samples, equipment decontamination <br /> and sample handling are presented below. <br /> SOIL BORING ADVANCEMENT <br /> Soil borings will be advanced using a van-mounted Geoprobe 5400 direct-push probing <br /> unit or equivalent AMS Powerprobe 9600 probing unit equipped with 1.25-inch probing <br /> rods. The Geoprobe advances soil probe borings using a hydraulic hammer to drive soil <br /> Advanced GeoCnvironmental,Inc. <br />
