• �W vtga • <br /> a <br /> San Joaquin County ® Page 5 <br /> Environmental Health Department <br /> June 9,2008 Project Number 99008-008073.03 <br /> the soil sample collected from approximately five feet bgs for TPH and VOC analyses. Soil samples will <br /> be analyzed on standard turn around time. If no groundwater is encountered, a second soil sample will <br /> be submitted for laboratory analysis from each boring from a deeper interval. <br /> Grab-Groundwater Samples—(Three) <br /> • VOCs by Method 82608 <br /> • TPH quantified as gasoline(TPH-g) by Method 8015M —3 grab-groundwater samples <br /> • Extractable TPH quantified as diesel (TPH-d) and motor oil (TPH-mo) by Method 8015M using <br /> silica gel cleanup (SGCU)—3 grab-groundwater samples <br /> Soil Vapor Samples—(Three) <br /> • VOCs by Method 82606 or TO-15 <br /> • Methane by ASTM Method D-1946 <br /> Task 4: Reporting <br /> Bureau Veritas will prepare a report documenting the findings based on the data collected from the <br /> subject property. Sample results will be compared to USEPA Region IX Preliminary Remediation Goals <br /> (PRGs), and/or California Human Health Screening Levels (CHSSLs), where appropriate. The report will <br /> describe the results of the subsurface investigation and provide recommendations. The report will include <br /> a boring location map(to scale), boring logs, a table summarizing the analytical data, and copies of the <br /> laboratory reports. Bureau Veritas will provide a copy of the final report to EDH. <br /> 3.0 SCHEDULE <br /> The proposed schedule for this project is outlined as follows: <br /> NUMBER OF BUSINESS DAYS <br /> ACTIVITY FROM AUTHORIZATION <br /> USA Site and Preliminary Field Visit, and Drilling Permit Application Submittal ..........................3-5 <br /> Mobilize to the Subject Property and Complete Onsite Sampling............................................10-15 <br /> Receive Laboratory Results(24-hour turn-around time) ..........................................................16-22 <br /> CompleteReport.......................................................................................................................30-35 <br /> SAESTROJECTSt3Chimp[991(15-16)\2008W8073 StocktcnThase 2/080947 Wkplan SJCo.doc <br />
