INTRODUCTION <br /> At the request of Ms.Mable Keir,Advanced GeoEnvironmental,Inc(AGE)has prepared this work <br /> plan for installation of ground water monitoring wells at 1601 Turnpike Road, Stockton,California <br /> (site). The location of the site is illustrated on Figure 1. A plan of the site is illustrated on Figure 2. <br /> This work plan is prepared in accordance with PHS-EHD and Central Valley Regional Water Quality <br /> Control Board(CVRWQCB) guidelines for the investigation of underground storage tanks (UST) <br /> sites. This work plan provides a description of the scope of work and procedures for the installation <br /> of three ground water monitoring wells. <br /> Background information is summarized in Appendix A. Previous ground water monitoring well <br /> installations are documented in AGE's Quarterly Report-4"Quarter 2004, dated 20 January 2005, <br /> and were conducted according to the Revised Work Plan, Monitoring Well Installation dated 16 <br /> August 2004, prepared by Kleinfelder Incorporated. <br /> 2.0. SCOPE OF WORK <br /> The lateral and vertical extent of hydrocarbon-impacted ground water has not been defined at the <br /> site. AGE proposes the following scope of work to further delineate the impacted ground water: <br /> • Permitting and pre-field work activities; <br /> • Pilot soil boring and sample collection; <br /> • Monitoring well installation and development; <br /> • Ground water sample collection; <br /> • Preparation of a report of findings. <br /> 2.1. PERMITTING AND PRE-FIELD WORK ACTIVITIES <br /> Applicable site assessment permits will be obtained from the PHS-EHD. In addition, an update to <br /> the health and safety plan presently on-file will be prepared in accordance with Occupational Safety <br /> and Health Guidance Manual for Hazardous Waste Site Activities (National Institute for <br /> Occupational Safety and Health Administration, U.S. Coast Guard and U.S. Environmental <br /> Protection Agency, 1985). Prior to mobilization, each monitoring well location will be clearly <br /> marked and a utility clearance obtained through Underground Service Alert. <br /> Advanced GeoEuvironmental,Inc. <br />
