Figure 1 presents the location of well <br /> • W-2. The 2-mch diameter polyvinyl chloride (PVC) cased monitoring well was destroyed <br /> because of an obstruction within the well at approximately 58 feet below ground surface (bgs) <br /> and replaced with a 4-mch diameter PVC cased well by Turner Explorations (California C-57 <br /> License Number 602720) of Rancho Cordova, California. Procedures for the destruction and <br /> replacement of the well followed procedures described in the work plan for the project, dated <br /> March 22, 1994. The work plan was reviewed and approved by San Joaquin County <br /> Environmental Health Division. <br /> Monitoring Well Construction The final well construction of the monitoring well included 20 <br /> feet of 0.020 slotted schedule 40 casing and 59 feet of blank schedule 40 casing. The total depth <br /> of the well is approximately 81 feet. A 24-foot sand pack extends from the bottom of the <br /> borehole to approximately 57 feet bgs. A 3-foot bentonite seal separates a cement grout, which <br /> extends to the surface, and the sand pack. <br /> Stockpiled soil was classified for disposal by Dillard Environmental Services (Dillard) of Byron, <br /> California and then transported from the facility by Dillard to BFI Landfill, a Class-III landfill, <br /> in Livermore, California. <br /> This report was prepared in accordance with the standards of the environmental consulting industry at the time it was <br /> prepared It should not be relied upon by parties other than those for whom it was prepared,and then only to the extent <br /> of the scope of work which was authorized.
