1 <br /> sand placement to eliminate bridging & voids Fill depths will <br />' be monitored constantly as the auger flights are slowly with- <br /> drawn When sand fill has stabilized, (a minimum of 2 ' above the <br /> top of the slots, ) a bentonite seal will be placed, and the <br /> annular space filled to the surface with a cement/bentonite <br />' slurry. Refer to PLATE II for a schematic of the proposed well <br /> completion. <br />' 9 . Each well will be fitted with a precast Christy-type box, <br /> with the PVC extending into the box far enough to allow placement <br /> of a locking casing cover The casing & box will be thoroughly <br />' grouted into place to ensure the integrity of the seal <br /> 10 Within 18-24 after completion, each well will be developed <br /> by use of a hard rubber cup or suitable device . Purge fluids <br />' will be placed in suitably marked sealed containers & stored on <br /> location pending results of laboratory analyzes <br />' 11 As soon as practical after development, each well will be <br /> purged, water levels determined, and water samples taken per <br /> standard San Joaquin County EHD field protocol . <br /> 12 Wellhead elevations & distances between wells will be <br /> determined by a licensed surveyor. <br />' After receipt and analysis of all of the data, a report will be <br /> prepared and submitted to the San Joaquin County EHD staff for <br /> review & comment . <br />' Pending written approval of this workplan, we will begin <br /> soliciting bids from qualified vendors . When all the required <br /> documents have been received, we will prepare a package for <br />' client to submit to the State Cleanup Fund staff for pre-approval <br /> of the work. When the expenditure of those funds has been <br /> approved, we will proceed with scheduling the work We will keep <br />' your o ?nter <br /> i formed of the status of this project . <br /> L� <br />' Wm & AssociatesR��OFe ru , 199& �cc • ntine <br />' MLIN1�UNfER <br /> i��9-7 <br />' * N4 860 <br /> sTq� <br /> OF CALIFo��P <br /> 7 <br />
