Condensation from vapor extraction is collected in moisture drop # <br /> out tanks constructed of 12" PVC pipe, before the manifold, to <br /> prevent moisture build up on the vacuum pump filter. All fluids <br /> Iremoved from the condensation traps are placed in the 1000. gallon <br /> "ConVault" . As of December 1, 1992 a total of 22 . 5 gallons of <br /> product and 162 gallons of water have been removed from the <br /> , condensation traps; 0 . 06 gallons product and 30 gallons water ;r <br /> ` from EX-4 , 9 . 18 gallons product and 66 . 93 gallons water from MW- <br /> 10 , and 13 . 23 gallons product and 65 . 09 gallons water from MW2/3 . f ; <br /> ih`hNo fluids have collected in the MW-1 condensation trap. The <br /> V "ConVault" was connected to the vapor recovery manifold on <br /> October 1, 1992 . Table 5 represents the field notes from LTT <br /> , condensate removal and well purging (MW2 and MW3 condensate into ` <br /> the same trap and the condensate removal is represented with MW2 <br /> data) . As of February 25, 1993 LTT has removed 2243 . 5 gallons of <br /> ground water from MW1, MW2 , MW3 , MW8, MW10 and water condensate ° <br /> 'Ffrom traps for MW2&3 , MW10, EX and 26 . 05 gallons of product from . <br /> ; the condensate traps. <br /> Total removal from the individual wells : MWl 275 gallons of <br /> aground water, MW2 557 . 85 gallons of ground water and condensate <br /> ' water and 22 .4 gallons of ,product, MW3 272 gallons of ground <br /> water, MW8 225 gallons of ground water, MW10 570 . 35 gallons of <br /> ground water and condensate water and 26 . 05 gallons of product <br /> ,Land EX 505 . 4 gallons of condensate water and 0 . 06_ gallons of <br /> 5 product . .Total fluids removed as of January 28, 1993 : 1272, <br /> gallons of- ground water and 46 .26 gallons of product . <br /> €i <br /> ,t <br /> 5 . 0 SUMMARY <br /> y Presently there is no floating product on the ground water or <br /> with the condensate recovered from the vapor extraction moisture ;F <br /> dropouts . <br /> On February 24, 1993 , a sample of the water being treated by air <br /> stripping inside the "ConVault" was obtained for certified <br /> laboratory analysis, before dumping approximately 1287 gallons of k <br /> this water to the City of Stockton' s sanitary sewer, see Table 4 <br /> P and Appendix A. <br /> j <br /> 3 As of March 11, 1993 , a total of 17670 gallons of gasoline range E <br /> hydrocarbons have been removed from the soil and ground water <br /> beneath this site.
