A JUNE 16, 1991 The "Cyclo Purge" was repaired and rejuvenation of the two 110 ' gallon carbon scrubs occurred on June 16, 1991 and vapor extraction commenced at 4:30 pm on .Tune 17, 1991, into the two 110 gallon carbon scrubs placed in series. JUNE 20, 1991 ` At 8:30 am, carbon #1 (110 gl #2996) was taken off line and two of r the "Cameron-Yakima" re3uvenated 85 gallon carbons scrubs (#1043 and #3044) were placed in parallel behind carbon #2 (110 gl #2995) . Low pressure injection of ambient air was started into wells MW2, 14W4, EX and P1. To augment subsurface circulation towards vapor extraction wells MW1, MW5 and P3, see Figure 6D. JUNE 24, 1991 Vacuum extraction occurring from wells MW1, MW5 and P3, with ambient air injection into wells MW2, MW4, P1 and EX. After the pumps the following carbons were in series; #1 110 gallon 2995, #2 85 gallon R1043, #3 85 gallon R1044 and #4 85 gallon R1045. JUNE 27, 1991 CF " erg " a di c �: a 1 C ( s o wl 0 At this time one 85 ga�o`n�` ( ) e also removed from the system and rejuvenated using the "Cyclo Purge". Carbon #R1043 was then placed in the number one position and a fresh carbon #R1041 was placed in series behind it. Vapor extraction was continued from MW1, MW5 and P3 with ambient air injection into wells MW2, MW4, P1 and EX, see Figure 6E. JULY 1, 1991 Carbon canisters R1043 and 81041 were placed in parallel after the pumps and exhausted into the 2 rejuvenated 110 gallon cansisters that were placed in series 02995 and #2996. Vacuum extraction from wells MW1, MW3 and P3 with ambient air injection into wells MW2, MW4, EX and P1. Prior to leaving the site, one 83 gallon carbon (#1044) was put on the of exhaust #2996. JULY 8, 1991 Manifest 3 85 gallon carbon scrubs (R1041, R1043 and R1045) along with the two 110 gallon carbons scrubs (2995 and 2996) to Cameron- Yakima for rejuvenation using Exceltrans, see Appendix 0.
