09 November 2004 <br /> AGE-NC Project No. 04-1224 <br /> Page 4 of 6 <br /> • Total petroleum hydrocarbons quantified as gasoline (TPH-g) in accordance with EPA <br /> Method 8015M; and <br /> • Volatile organic compounds,including benzene,toluene,ethylbenzene and xylenes(BTEX), <br /> and methyl tertiary-butyl ether(MTBE) in accordance with EPA Method 8260M. <br /> Laboratory reports for soil and ground water analyses, testing methods, laboratory quality <br /> assurance/quality control (QA/QC) reports, and sample chain of custody documentation will be <br /> presented in a report with findings and recommendations. <br /> 3.3. 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,and <br /> maps will be included in the report. <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 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 a 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 /> hammer to drive soil sampling tools to specified depths. <br /> 4.2. SOIL SAMPLING COLLECTION AND ANALYSIS <br /> Soil borings will be sampled at discreet five-foot intervals using a 1.125" Geoprobe soil sampling <br /> assembly loaded with four six-inch brass sleeves. Upon sample retrieval, the ends of the second <br /> sleeve will be covered with Teflon sheets, capped and sealed with tape. <br /> Advanced GeoEnvironmental,Inc. <br />
