Corrective Action Plan <br /> Montgomery Ward Auto Service Center, Stockton, CA <br />' inch tubing was inserted through the 1-inch pipe such that the tubing extended from the top <br /> of the blank casing to 1 foot below the packer The complete 1-inch assembly was inserted <br /> inside the 2-inch casing of VEW-113 such that the packer was located at 64 ft bgs Oust <br /> above the lowest screened interval) and the 318-inch tubing extended 1 foot below the <br />' packer At ground level, the 318-inch tubing can be connected to a air sparging unit <br /> In addition to the well screens in the vadose zone, wells VEW-3, VEW-4 and VEW-5 are <br /> also screened across the top of the ground water table (between 40 and 50 feet bgs) to <br /> allow monitoring ground water conditions (e g dissolved oxygen level and contaminant <br /> concentration) around sparging well VEW-1B <br /> ExistingSoil oil Vapor Probes <br /> The location of all existing soil vapor probes are shown in Figure 12 Construction details <br />' for all soil vapor probes are provided in Table 9 and Appendix B The probes were <br /> constructed to allow monitoring at specific distances away from the main nested extraction. <br /> wells (VEW lA and VEW-1B and VEW-2 and VEW-213) and at specific depths below <br />' ground surface Probes SP-1 and SP-7 were completed as nested dual probes at depths of <br /> 20 feet bgs (SP-1A and SP-7A) and 35 feet bgs (SP-113 and SP-7B ) The other probes <br /> (SP-2 to SP-6) were all completed at a single depth of 25 feet bgs The relative distance of <br /> each probe from the two main vapor extraction system wells, and the depth of the probe <br /> below ground surface, are as follows <br /> PROBE DISTANCE (FT) DISTANCE (FT) <br /> NUMBER FROM VEW-lA FROM VEW-113 DEPTH (FT) <br /> SP-1A 25 20 20 <br /> SP-113 25 20 35 <br />' SP-2 14 14 25 <br /> SP-3 35 35 25 <br /> SP-4 36 41 25 <br />' SP-5 112 112 25 <br /> SP-6 102 100 25 <br /> SP-7A 60 60 20 <br />' SP-713 60 60 35 <br /> SP-8 40 43 35 <br /> PROBE DISTANCE (FT) DISTANCE (FT) <br />' NUMBER FROM VEW-2 FROM VEW-2B DEPTH (FT) <br /> SP-IA 101 99 20 <br /> SPAB 103 101 35 <br /> SP-2 79 77 25 <br /> SP-3 126 124 25 <br /> SP-4 93 92 25 <br />' SP-5 20 24 25 <br /> SP-6 43 40 25 <br /> SP-7A 32 30 20 <br /> SP-7B 33 30 35 <br /> SP-8 60 60 35 <br /> Protect No 1232 - 23 - <br />' SMI WORT)1232CAP <br />
