R603 UPDATE-11 11/19/92 exchanger malfunctioned and the incinerator shut down due to low temperature. The unit remained off until it was replaced on August 18 , 1992 with a new unit. At the present (November 17 , 1992) the REMOX units have operated for a total of 5388 hours out of a total of 8821 . 5 hours ( 61% ) . The new replacement unit has operated 1386 hours out of 2174 .5 hours (64% ) , removing and destroying 39542 pounds of gasoline range hydrocarbons. Since replacing the unit on August 18, 1992, the REMOX has removed/destroyed 13703 pounds or 9 . 9 pounds per operational hour, see Tables 2 and 3 and Appendix B-Air Monitoring Reports. Condensation from vapor extraction is being collected in moisture drop out tanks constructed of 12" PVC pipe, prior to the manifold, to prevent moisture build up on the vacuum pump filter. All fluids removed from the condensation traps are placed into the 1000 gallon "ConVault" within the treatment compound. As of November 17 , 1992, a total of 10 . 27 gallons of product and 111 . 59 gallons of water have been removed from the condensation traps; 0 .06 gallons product and 18 . 73 gallons water from EX411 , 3 . 98 gallons product and 53 . 13 gallons water from MW-10 , and 6 . 23 gallons product and 39 . 73 gallons water from MW2/3 . No flu-ids have collected in the MW-1 condensation trap. The ConVault was hooked into the vapor recovery manifold on October 1, 1992. At this time there is no floating product on the stored water surface within the ConVault. Observations made on October 8 , 1992, showed that the floating product had been removed by the vacuum placed onto the ConVault. A water sample was then obtained and analyzed thru WEGE ' s non certified laboratory and showed the stored water had 30 . 5 Mg/L gasoline range hydrocarbons (TFH) , 0 . 994 Mg/L benzene, 9 . 679 Mg/L toluene, and 23 . 96 Mg/L xylenes. Another water sample was obtained of the Convault water on October 13, 1992, and again analyzed by WEGE, non certified. Tne water was dramatically reduced an hydrocarbons and showed the following concentrations: TFH 7 . 78 Mg/L, benzene 0 . 125 Mg/L, toluene 2. 953 Mg/L and xylenes 7 . 362 Mg/L. " ^ Tib ' 1 92 }^}3i Of 6377 .24 gallons of gasoline A Oi November 1 , , , 3 ��.. g y range hydrocarbons have been removed from the soil and ground water beneath this site with the condensation traps recovery, including previously removed floating product ( 40 . 25 gallons) and vapor extraction-destruction of hydrocarbons ( 39542 pounds/6 . 25 = 6326 . 72 gallons) . No chlor-Lilar-ed solveRts have been detected in chromatogram comparisons; le. 1 , 2 , -D-ichloroethane (DCE) - retention time 2 . 079 minutes, Trichloroethylene (TCE) - retention time 3 . 023 minutes and Tetrachloroethylene (PCE) - retention time 3 . 75 minutes.
