Geosyntec® consultants • Groundwater samples will be collected using the low-flow pump and transferred into sample containers prepared by the analytical laboratory; and, • Sample containers.will be sealed, labeled, and then placed in a cooler with ice for transport to the laboratory. A blind duplicate sample will be collected from one well. One equipment blank will be collected during each day of groundwater sampling. Trip blanks consisting of organic- free, deionized water will be prepared by the laboratory and will accompany the sample containers during transport to, during, and after sampling. The trip blank sample bottles will not be opened. Groundwater and QA/QC samples will be handled under standard chain of custody procedures and will be analyzed for toluene by EPA Method 8260. .Purged water will be contained in drums, labeled, and remain at the facility, pending appropriate disposal. 2.3.6 Disposition of Waste Materials There will be some decontamination water generated during field work in addition to the purge water and soil cuttings. Before leaving the Site, Geosyntec will collect a composite sample of the purge water and decontamination water and a composite sample of the soil cuttings for waste classification. Following classification, the waste will be disposed of at an appropriate off.-site facility. 2.4 Task 4—Reporting and Recommendations for Follow-up Work Geosyntec will evaluate the data collected during Tasks 1, 2, and 3 and prepare a report documenting the work completed and summarizing the results for submittal to the RWQCB. The report will include CPT and MIP logs for each boring, well construction logs, analytical results, and summary tables and figures including one or more geologic cross-sections for the investigation area. Based on the results, conclusions and recommendations for future work will be made, as warranted. Final Work Plan.doc 13 27 June 2012
