11 May 2009 AGE-NC Project No. 09-1692 Page 4 of 6 • Total petroleum hydrocarbons quantified as diesel(TPH-d)in accordance with EPA Method 8015M and • Benzene, toluene, ethylbenzene and xylenes (BTEX) in accordance with EPA Method 8260B. Laboratory reports for soil analyses, testing methods, laboratory quality assurance/quality control (QA/QC) reports, and sample chain of custody documentation will be presented in a report with findings and recommendations. 3.3. REPORT PREPARATION Upon completion of field work and receipt of final laboratory analysis, a report will be prepared presenting the findings of the investigation and signed by a California Professional Geologist. The report will include a description of the work performed and results of the sampling and analysis. Conclusions, applicable recommendations, and maps will be included in the report. 4.0. FIELD PROCEDURES All field procedures will be overseen by an AGE representative under the supervision of a California Professional Geologist.Procedures for the advancement of soil borings,soil sampling,ground water sampling, equipment decontamination and sample shipment are outlined below. 4.1. SOIL BORING ADVANCEMENT a Soil borings will be advanced using a van-mounted Geoprobe 5400 direct-push probing unit equipped with 1.25-inch probing rods or a 1.5-inch Geoprobe macro-core soil sampling assembly. The Geoprobe advances soil borings using a hydraulic hammer to drive soil and ground water sampling tools to specified depths. 4.2. SOIL SAMPLING COLLECTION AND ANALYSIS Soil samples will be collected at approximate 2.5-foot intervals beginning at 2.5 feet bsg using a 1.25-inch Geoprobe soil sampling assembly loaded with four six-inch stainless steel sleeves ora 1.5- inch Geoprobe macro-core soil sampling assembly loaded with four-foot acetate sleeves.
