S E C O R - ---. __ - <br /> 2.2.5 Groundwater Sample Collection and Analysis <br /> After well development, groundwater samples will be collected and submitted under <br /> chain-of-custody (COC) documentation to Kiff Analytical, a state certified laboratory located in <br /> Davis, California and will be analyzed for the following: <br /> • TPHd and TPHo by Environmental Protection Agency (EPA) Method 8015M <br /> • TPHg; benzene, toluene, ethylbenzene, and total xylenes (BTEX compounds); fuel <br /> oxygenates (MtBE, di-isopropyl ether [DIPE], ethyl tertiary butyl ether [EtBE], TBA, <br /> tertiary amyl methyl ether [TAME], methanol, and ethanol); and volatile organic <br /> compounds (VOCs) by EPA Method 82608 <br /> • Semi-volatile organic compounds (SVOCs) by EPA Method 8270C <br /> • Dissolved metals by EPA 6000/7000 Series (during first and third quarters only per <br /> requirements outlined in the MRP (No. R5-2004-0820) <br /> Based on the timing of well installation and development activities, the groundwater samples <br /> may be collected during the routine quarterly monitoring and sampling event for the Site. <br /> 2.2.6 Well Surveying and EDF Upload <br /> Upon completion of well construction, the wells will be surveyed by a licensed surveyor to a <br /> local benchmark relative to mean sea level. In order to comply with the State of California <br /> Water Resources Control Board location requirements, the latitude and longitude (degree, <br /> minutes, seconds) location of each well will also be surveyed. Survey data including elevation, <br /> longitude, and latitude will be included in information uploaded to the state GeoTracker <br /> database. <br /> 2.2.7 Soil and Water Disposal <br /> All investigation derived waste (IDW), including soil cuttings and purge water from well <br /> installation and development will be stored on-site in Department of Transportation-approved <br /> 55-gallon drums and/or roll off bins pending the results of chemical analyses. Analytical results <br /> will be used for waste profiling and disposal. After profiling, IDW will be transported and <br /> disposed at an appropriate disposal facility. <br /> Field and laboratory procedures are presented as Appendix B. <br /> Additional Deep Zone Assessment Work Plan.final.doc <br /> Tidewater Stockton <br /> March 14,2008 <br /> 6 <br />
