R603 UPDATE-13 2/15/93 <br /> hydrocarbons removed from the subsurface, see Tables 2, 3 and 5 <br /> and Appendix A-Air Monitoring Report . <br /> CONDENSATE REMOVAL AND WELL PURGING BY LTT <br /> 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 /> removed 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 <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 . <br /> No fluids have collected in the MW-1 condensation trap . The <br /> "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 January 28, 1993 LTT has removed the following from <br /> the monitor wells and condensate traps in gallons : <br /> ground condensate total water product <br /> water water <br /> MWl 165 0 165 0 <br /> MW2 47 194 7 241 . 7 9 . 2 <br /> MW3 165 W/MW2 W/MW2 W/MW2 <br /> MW8 135 0 135 0 <br /> MW10 43 178 9 221 9 14 6 <br /> EX 0 181 . 95 181 . 95 0 <br /> Total removal from the individual wells, MW1 165 gallons of <br /> ground water, MW2 306 8 gallons of ground water and condensate <br /> water and 22 4 gallons of product, MW3 165 gallons of ground <br /> water, MW8 135 gallons of ground water, MW10 288 8 gallons of <br /> ground water and condensate water and 23 . 8 gallons of product and <br /> EX 212 gallons of condensate water and 0 . 06 gallons of product . <br /> Total fluids removed as of January 28 , 1993 1272 gallons of <br /> ground water and 46 26 gallons of product <br /> Presently there is no floating product on the stored water <br /> surface within the "ConVault" . Observations made on October 8, <br /> 1992, showed that the floating product had been removed by the <br /> Vacuum pia(_e 1 (into 'lle ��ConVaultA water ScLlTlple was tllcii <br /> obtained and analyzed through WEGE' s non certified laboratory and <br /> showed the stored water had 30 5 Mg/L gasoline range hydrocarbons <br /> (TFH) , 0 994 Mg/L benzene, 9 679 Mg/L toluene, and 23 . 96 Mg/L <br /> xylenes . <br /> A water sample was obtained of the "Convault" water on October <br /> 13 , 1992 , and again analyzed by WEGE, non certified. The water <br /> was dramatically reduced in hydrocarbons and showed the following <br /> concentrations TFH 7 78 Mg/L, benzene 0 . 125 Mg/L, toluene 2 953 <br /> PAGE 8 <br />
