27 November 2001 AGE-NC Project No. 01-0856 Page 4 of 5 • Total petroleum hydrocarbons as gasoline(TPH-g),diesel(TPH-d),and motor oil(TPH-mo) by EPA Method 8015 Modified; • Volatile organic compounds by EPA Method 8260; • LUFT metals, including Zn,Cu, Ni, Cr and Pb in accordance with EPA Method 6010; and • PNAs by EPA Method 8270. 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. 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. The report will be in a format acceptable to the PHS-EHD and the CVRWQCB, and will be reviewed and signed by a California Registered Geologist. 4.0. FIELD PROCEDURES All field procedures will be overseen byan AGE representative under the supervision of a California Registered Geologist. Procedures for the advancement of borings, soil sampling, equipment decontamination and sample shipment are outlined below. 4.1. PROBE BORING ADVANCEMENT Probe borings will be advanced using a van-mounted Geoprobe 5400 direct-push probing unit equipped with 1.125-inch probing rods.The Geoprobe advances borings using a hydraulic hammer to drive soil sampling tools to specified depths. 4.2. SOIL SAMPLING COLLECTION AND ANALYSIS Soil probe borings will be sampled at discreet five-foot intervals beginning at five feet bsg using a 1.25' Geoprobe soil sampling assembly loaded with four six-inch brass sleeves. Upon sample retrieval,the ends of the selected sleeve will be covered with Teflon sheets, capped and sealed with Advanced GeoEnvironmental,Inc.
