02 June 2006 <br /> AGE-NC Project No. 06-1434 <br /> Page 3 of 4 <br /> laboratory for one or more the following constituents: <br /> • Total petroleum hydrocarbons quantified as gasoline (TPH-g) and diesel (TPH-d) in <br /> accordance with EPA Method 8015M; <br /> • Benzene, toluene, ethylbenzene and xylenes (BTEX), and volatile organic compounds <br /> (VOCs) in accordance with EPA Method 826013; and <br /> • LUFT Metals Cadmium,Chromium,Zinc,Lead and Nickel in accordance with EPA Method <br /> 200.8 <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 /> 4.3. REPORT PREPARATION <br /> Upon completion of field work and receipt of final laboratory analyses, 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 /> 5.0. FIELD PROCEDURES <br /> All field procedures will be overseen by an AGE representative under the supervision of a California <br /> Professional Geologist. Procedures for the advancement of borings, soil sampling, equipment <br /> decontamination and sample shipment are outlined below. <br /> 5.1. 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 /> 5.2. SOIL SAMPLE COLLECTION AND ANALYSIS <br /> At a minimum,soil borings will be sampled at discreet five-foot intervals using a 1.5-inch Geoprobe <br /> Advanced GeoEnvironmentel,Inc. <br />
