GEOMsaTRIX <br /> holding containers on site After monitoring well installation and development are complete, <br />' the location and elevation of the well wiII be surveyed by a licensed land surveyor <br />' 2.2 GROUNDWATER SAMPLING <br /> Groundwater samples will be collected initially from the newly installed monitoring well and <br />' then will be incorporated into the regular monitoring round for the three previously-installed <br /> monitoring wells at this site Prior to sampling each well, the presence of free-floating PHC <br /> product will be assessed using a clear Teflon or acrylic bailer The water level will then be <br />' obtained using an electroiuc sounder Subsequently, at least three casing volumes will be <br /> purged from the well Field parameters will be measured periodically during purging, and <br />' samples will be collected when parameters reach relatively constant values A clean, decon- <br /> tammated, Teflon or acrylic bailer will be used to collect the water sample for laboratory <br />' analysis <br /> Groundwater samples will be preserved and transported under chain-of-custody procedures to <br />' Precision Enviro-Tech, a California ELAP-certified laboratory, for PHC analysis The samples <br /> will be analyzed for BTEX using EPA Method 8260 and for TPH-g using EPA Method 8015m <br /> 2.3 TECHNICAL REPORT <br />' Upon completion of the field investigation and laboratory testing, a technical report will be <br /> prepared documenting the field activities and summarizing the results of the exploration boring <br />' and monitoring well sampling The report will include figures depicting the exploration boring <br /> and monitoring well locations, existing site features, and groundwater gradient It will also <br /> include tabulated analytical results, hthologic and well construction logs, and copies of permits <br /> obtained for the work <br /> 2.4 HEALTH AND SAFETY <br /> The Health and Safety plan for this subsurface investigation is contained in Ross (1999), <br /> Appendix A A copy of this plan will be available on site during the field work This plan is <br /> not intended for use by other contractor's personnel involved with this work <br />' 3.0 SCHEDULE <br /> It is estimated that the proposed scope of work can be completed within about 8 to 10 weeks <br /> following approval of this plan, depending upon drilling subcontractor availability <br /> I\PROIECl16437 00016437 Wk Pln Site 3 doc 7 <br />
